+ | |||
+ | The Axe-Fx III has two expression pedal or switch inputs. An expression pedal should have a linear resistance taper, max resistance of 10-100 kOhm, and requires a TRS-to-TRS cable. The pedal must be calibrated before use (I/O > Pedal). | ||
+ | |||
+ | An external switch can be a momentary or latching one, and uses a TS-to-TS cable. Use I/O > Pedal to let the hardware know what type of external switch you're connecting, and to calibrate connected pedals. | ||
+ | |||
+ | The Owner's Manual contains tutorials about connecting, calibrating and configuring a pedal, either connected directly to the device, or via another controller. | ||
+ | |||
+ | Unlike the previous generation of hardware, the Axe-Fx III now allows selecting a pedal or switch directly as a modifier source (without assigning it to an external controller first). | ||
+ | |||
+ | The [[FC-6 and FC-12]] controllers also allow connecting expression pedals and switches. These are configured in the Setup > Foot Controllers menu. [http://wiki.fractalaudio.com/axefx2/index.php?title=FC-6_and_FC-12 More information.] | ||

+ | |||
+ | Axe-Fx III Owner's Manual: | ||
+ | <blockquote>"TRS” stands for TIP-RING-SLEEVE and describes the configuration of a 1/4" end plug or jack with three connectors. Normal guitar cables are “TS” (Tip-Sleeve) since they lack the ring required for a third contact. Expression pedals require TRS cables because full control voltage is transmitted to them on one contact (the tip), while less than full voltage is returned to on another (the ring) so the host device is able to sense and utilize the pedal position. The third contact (sleeve) is connected to ground."</blockquote> | ||
+ | |||
+ | ==Setting up a global volume pedal== | ||
+ | |||
+ | This is covered in the Owner's Manual. | ||
+ | |||
+ | Note: the FX8 lets you specify the exact position of the volume control. | ||
+ | |||
+ | =When the pedal is not connected= | ||
+ | |||
+ | When a pedal is not connected, the device needs to know what value to use. Disconnecting a Volume pedal should not mute the device, for example. The desired initial value can be selected in the MIDI menu, through External Controller Initial Value. | ||
+ | |||
+ | Note: this applies only to pedals that have been assigned to an external controller through an "external controller", so not to pedals that are directly connected to the device. | ||
+ | |||
+ | ==Overrule the bypass state of effect blocks with an external switch== | ||
+ | |||
+ | You can use an external switch to set the bypass state of an effect block and maintain that state when switching presets. | ||
+ | # Connect the switch to a PEDAL jack. | ||
+ | # Assign that PEDAL to an External Controller. | ||
+ | # Assign the Bypass Mode parameter of the effect to that External Controller (modifier menu: Source). Repeat this in each preset which you want to control. | ||
+ | # Now the switch will control the effect's engaged/bypass state, regardless of the effect's stored state, and stay in sync. | ||
+ | |||
+ | ==Using a pedal to control the wet level of effects== | ||
+ | |||
+ | You can use an expression pedal to control the overall "wetness" (effect level of multiple/all effect blocks): | ||
+ | # Connect and calibrate your expression pedal. | ||
+ | # In I/O set one of the EXTERNAL controllers to "PDL" (let's use EXT1 in this example) | ||
+ | # Create your preset with the reverb and delay at their most extreme (wet) settings. | ||
+ | # Open the DELAY block for editing. | ||
+ | # Select the INPUT GAIN parameter and press ENTER to show the MODIFIER screen. | ||
+ | # Set the SOURCE of the modifier to EXT1. Press EXIT 2x to return to the grid. | ||
+ | # Select the REVERB block and repeat steps 4, 5, and 6. | ||
+ | # Save the preset. | ||
+ | # The pedal will now blend between full wet and full dry. [http://forum.fractalaudio.com/floor-controllers-midi-cc-questions/38163-controlling-effect-wetness-using-expression-pedal.html#post522146 source] | ||

+ | |||
+ | ==Let a single pedal control different effects== | ||
+ | |||
+ | Method 1 (i.e. control either Wah or Whammy): | ||
+ | # Insert a Wah block. | ||
+ | # Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to to the main row. | ||
+ | # In the Modifier menu of BOTH effects (Wah: Frequency; Pitch: Control): set Source to External 1. Enable Auto-engage. | ||
+ | # Add a Mixer block to the main row, just after Wah and Pitch. | ||
+ | # Edit Mixer: enter the Modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to another external controller (which will be attached to an IA-switch to switch between Wah and Whammy). Set Start Value to 100% and End Value to 0. | ||
+ | # Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%. | ||
+ | # Program an IA switch to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy. | ||
+ | # That's all. Moving the pedal should activate both the Wah and the Pitch block. But thanks to the Mixer block you'll only hear one of these effects. If you're hearing the Wah and the Whammy effects simultaneously, you need to press the IA-switch to get the Mixer block to work | ||
+ | |||
+ | Method 2 (i.e. control Volume and Wah): (source: Bakerman) | ||
+ | # Place a Volume block on the grid. | ||
+ | # Assign an IA switch to an external controller's CC. | ||
+ | # Assign another external controller the Wah and Volume control knobs. | ||
+ | # Set the first external controller as a Bypass modifier for both blocks and reverse the slope of one (start 100, end 0). | ||
+ | # Now the IA switch will toggle between Wah/Volume and the pedal will control both. | ||
+ | |||
+ | Method 3 (use scenes to switch the pedal to another effect, i.e. Wah, Whammy and Volume): | ||
+ | # Put Wah and Pitch and Volume in one column (parallel). | ||
+ | # Assign an external controller (pedal) to the effects. Set to Auto-Engage in Wah and Pitch. | ||
+ | # In Wah and Pitch turn down Level in the block's Y state. | ||
+ | # Scene 1 is for Wah. Set Wah to X, set Pitch to Y, bypass Volume. | ||
+ | # Scene 1 is for Whammy. Set Wah to Y, set Pitch to Y, bypass Volume. | ||
+ | # Scene 3 is for Volume. Set Wah to Y, set Pitch to Y, engage Volume. | ||
+ | # To make this work with effcts without X/Y support, [http://forum.fractalaudio.com/axe-fx-ii-wish-list/77285-ring-mod-x-y.html#post954149 use a scene controller]. | ||
+ | |||
+ | ==Controlling multiple effects simultaneously with a pedal or switch== | ||
+ | |||
+ | It's possible to use your expression pedal for multiple purposes while staying in the same preset. Suppose you have one expression pedal and you want it to use as a wah as well as a Whammy, without switching presets: | ||
+ | # Insert a Wah block. | ||
+ | # Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to to the main row. | ||
+ | # In the Modifier menu of BOTH effects (Wah: Frequency parameter; Pitch: Control parameter): set Source to the External controller that's attached to your expression pedal. Set auto-engage to Fast, Medium or Slow. | ||
+ | # Add a Mixer block to the main row, just after Wah and Pitch. | ||
+ | # Editing the Mixer: enter the Modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to the external controller that is or will be attached to an IA-switch (which switches between Wah and Whammy). Set Start Value to 100% and End Value to 0. | ||
+ | # Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%. | ||
+ | # Program an IA-switch on your MIDI controller to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy. | ||

+ | |||
+ | The PEDAL jack lets you use a single switch to switch presets. This works fine if you have just a few presets to switch between.

Remote control of Fractal Audio's processors
Fractal Audio's hardware processors can be remotely controlled in the following ways:
- Software (through MIDI / MIDI-over-USB)
- Directly connected expression pedals, and latching or momentary switches (through TS / TRS cables)
- MIDI
- Fractal Audio's MFC-101 and FC controllers (through MIDI, Ethernet, EtherCON or FASLINK), including connected pedals and switches
- Onboard switches on the AX8 and FX8
The possibilities depend on the processor. More information:
- AX8
- FX8
- EV-1 and EV-2 pedals
- FC controllers
- FASLINK
- MIDI
- Software editors
- RJM Mastermind GT, FAMC Liquid Foot+
- FracPad
- Control Switches (see below)
- USB connections and audio
- Connecting and setting levels
- AxeForLemur (see below)
Controlling other devices with a Fractal Audio processor
Fractal Audio's hardware processors can control other devices through MIDI. The FX8 also provides relays to control other gear.
See:
Control Switches
A Control Switch is a switch on an AX8 or an FC controller that is assigned as a source in a parameter's modifier menu.
A Control Switch lets you e.g. assign a function in the Amp block, like Input Boost, directly to an onboard switch.
The state of a Control Switch is saved per scene.
AX8: the AX8 has two Control Switches, which can be assigned globally or per-preset like any other footswitch block from the main Footswitch (“FS”) page.
To set up a Control Switch footswitch:
- On the Footswitch (“FS”) page, use the NAV and A knobs to assign CS1 or CS2 to footswitch 1 – 8.
- Add a modifier to the desired effect parameter, setting “CTRL SW1” or "CTRL SW2” as the source.
- Adjust the modifier to work as desired.
To set initial values for a Control Switch:
- From the main FOOTSWITCH (“FS”) page of the AX8, page right to the CONFIG page.
- Select the CONTROLLERS option and press <ENTER>.
- Page to the CONTROL SWITCH (“CTRL SW”) page.
- Set the initial value of each switch for each scene to either “ON” or “OFF”.
Axe-Fx III: there are 6 Control Switches. Their states are stored per scene: On, Off, or LAST. Default is Off. The "per scene" settings can be accessed from the CS PER SCENE page in the Controllers menu.
Expression pedals and external switches
Number of onboard jacks for expression pedals or switches
- Axe-Fx III: 2.
- Axe-Fx II Mark I/II: 1.
- Axe-Fx II XL/XL+: 2.
- FX8: 4.
- AX8: 2.
Modifiers and external controllers
Pedals and switches can be connected directly to certain functions, or be assigned to an external controller which operates as a source of a modifier parameter. Read more about modifiers and external controllers.
AX8 and FX8
The jacks are meant to connect expression pedals such as the Fractal Audio EV-1 and/or external switches.
An expression pedal should have a linear resistance taper, max resistance of 10 kOhm to 100 kOhm, and requires a TRS-to-TRS cable. The pedal must be calibrated before use (I/O > PEDAL).
An external switch can be a momentary or latching one, and uses a TS-to-TS cable.
Use the I/O > PEDAL menu to let the hardware know what type of external switch you're connecting:
- when a latching (aka "toggle") switch is connected, set TYPE to “LATCHING”.
- when a momentary switch (such as a sustain pedal) is connected, you have two options:
- set TYPE to “MOMENTARY” and the device will recognize alternate stomps as ON and OFF, creating a “virtual” latching footswitch.
- set TYPE to “CONTINUOUS” if you want the switch to turn on when you press, and off when you release it.
"The Pedal inputs are not configured to handle two switches". source
"The FX8 pedal assignments are always global." source
"Pedals are always running. If nothing is plugged in there is a pull-up resistor that pulls the pedal value to 100%." source
The FX8 also has provides relay outputs which can be used to switch amp channels and such. Read this.
Axe-Fx III
The Axe-Fx III has two expression pedal or switch inputs. An expression pedal should have a linear resistance taper, max resistance of 10-100 kOhm, and requires a TRS-to-TRS cable. The pedal must be calibrated before use (I/O > Pedal).
An external switch can be a momentary or latching one, and uses a TS-to-TS cable. Use I/O > Pedal to let the hardware know what type of external switch you're connecting, and to calibrate connected pedals.
The Owner's Manual contains tutorials about connecting, calibrating and configuring a pedal, either connected directly to the device, or via another controller.
Unlike the previous generation of hardware, the Axe-Fx III now allows selecting a pedal or switch directly as a modifier source (without assigning it to an external controller first).
The FC-6 and FC-12 controllers also allow connecting expression pedals and switches. These are configured in the Setup > Foot Controllers menu. More information.
Axe-Fx II
The Mark I and II models have a single PEDAL jack. The XL and XL+ have two. An external switch can be a momentary or latching one, and uses either a TS or TRS cable.
Use the I/O > PEDAL menu to let the hardware know what type of external switch you're connecting:
- when a latching (aka "toggle") switch is connected, set TYPE to “LATCHING”.
- when a momentary switch (such as a sustain pedal) is connected, you have two options:
- set TYPE to “MOMENTARY” and the device will recognize alternate stomps as ON and OFF, creating a “virtual” latching footswitch.
- set TYPE to “CONTINUOUS” if you want the switch to turn on when you press, and off when you release it.
MFC-101
Read this: MFC-101.
What are TRS and TS cables
Axe-Fx III Owner's Manual:
"TRS” stands for TIP-RING-SLEEVE and describes the configuration of a 1/4" end plug or jack with three connectors. Normal guitar cables are “TS” (Tip-Sleeve) since they lack the ring required for a third contact. Expression pedals require TRS cables because full control voltage is transmitted to them on one contact (the tip), while less than full voltage is returned to on another (the ring) so the host device is able to sense and utilize the pedal position. The third contact (sleeve) is connected to ground."
Setting up a global volume pedal
This is covered in the Owner's Manual.
Note: the FX8 lets you specify the exact position of the volume control.
When the pedal is not connected
When a pedal is not connected, the device needs to know what value to use. Disconnecting a Volume pedal should not mute the device, for example. The desired initial value can be selected in the MIDI menu, through External Controller Initial Value.
Note: this applies only to pedals that have been assigned to an external controller through an "external controller", so not to pedals that are directly connected to the device.
Overrule the bypass state of effect blocks with an external switch
You can use an external switch to set the bypass state of an effect block and maintain that state when switching presets.
- Connect the switch to a PEDAL jack.
- Assign that PEDAL to an External Controller.
- Assign the Bypass Mode parameter of the effect to that External Controller (modifier menu: Source). Repeat this in each preset which you want to control.
- Now the switch will control the effect's engaged/bypass state, regardless of the effect's stored state, and stay in sync.
Using a pedal to control the wet level of effects
You can use an expression pedal to control the overall "wetness" (effect level of multiple/all effect blocks):
- Connect and calibrate your expression pedal.
- In I/O set one of the EXTERNAL controllers to "PDL" (let's use EXT1 in this example)
- Create your preset with the reverb and delay at their most extreme (wet) settings.
- Open the DELAY block for editing.
- Select the INPUT GAIN parameter and press ENTER to show the MODIFIER screen.
- Set the SOURCE of the modifier to EXT1. Press EXIT 2x to return to the grid.
- Select the REVERB block and repeat steps 4, 5, and 6.
- Save the preset.
- The pedal will now blend between full wet and full dry. source
Using a pedal to morph between clean and dirty tones
Tutorial by Cooper Carter for G66.
Let a single pedal control different effects
Method 1 (i.e. control either Wah or Whammy):
- Insert a Wah block.
- Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to to the main row.
- In the Modifier menu of BOTH effects (Wah: Frequency; Pitch: Control): set Source to External 1. Enable Auto-engage.
- Add a Mixer block to the main row, just after Wah and Pitch.
- Edit Mixer: enter the Modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to another external controller (which will be attached to an IA-switch to switch between Wah and Whammy). Set Start Value to 100% and End Value to 0.
- Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%.
- Program an IA switch to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy.
- That's all. Moving the pedal should activate both the Wah and the Pitch block. But thanks to the Mixer block you'll only hear one of these effects. If you're hearing the Wah and the Whammy effects simultaneously, you need to press the IA-switch to get the Mixer block to work
Method 2 (i.e. control Volume and Wah): (source: Bakerman)
- Place a Volume block on the grid.
- Assign an IA switch to an external controller's CC.
- Assign another external controller the Wah and Volume control knobs.
- Set the first external controller as a Bypass modifier for both blocks and reverse the slope of one (start 100, end 0).
- Now the IA switch will toggle between Wah/Volume and the pedal will control both.
Method 3 (use scenes to switch the pedal to another effect, i.e. Wah, Whammy and Volume):
- Put Wah and Pitch and Volume in one column (parallel).
- Assign an external controller (pedal) to the effects. Set to Auto-Engage in Wah and Pitch.
- In Wah and Pitch turn down Level in the block's Y state.
- Scene 1 is for Wah. Set Wah to X, set Pitch to Y, bypass Volume.
- Scene 1 is for Whammy. Set Wah to Y, set Pitch to Y, bypass Volume.
- Scene 3 is for Volume. Set Wah to Y, set Pitch to Y, engage Volume.
- To make this work with effcts without X/Y support, use a scene controller.
Controlling multiple effects simultaneously with a pedal or switch
It's possible to use your expression pedal for multiple purposes while staying in the same preset. Suppose you have one expression pedal and you want it to use as a wah as well as a Whammy, without switching presets:
- Insert a Wah block.
- Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to to the main row.
- In the Modifier menu of BOTH effects (Wah: Frequency parameter; Pitch: Control parameter): set Source to the External controller that's attached to your expression pedal. Set auto-engage to Fast, Medium or Slow.
- Add a Mixer block to the main row, just after Wah and Pitch.
- Editing the Mixer: enter the Modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to the external controller that is or will be attached to an IA-switch (which switches between Wah and Whammy). Set Start Value to 100% and End Value to 0.
- Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%.
- Program an IA-switch on your MIDI controller to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy.
- This is it. Moving the pedal should activate both the Wah and the Pitch block. But thanks to the Mixer block you'll only hear one of these effects. To bypass the effect hold the pedal in toe-down position. If you're hearing the Wah and the Whammy effects simultaneously, you need to press the IA-switch to get the Mixer block to work.
You don't have to use a Mixer block (available on the Axe-Fx only). Here's how, or or read this for another solution:
- Do the same as above but leave out the Mixer block.
- Set Bypass mode of one block to Thru and the other block to Mute.
- Assign an External controller (attached to a switch) to the Balance parameter in each block. Set Start Value to 100% and End Value to 0 in one block, andvice versa in the other.
- Set Input Select in Drive and Amp blocks after Wah and Pitch to Left or Right, instead of Sum L+R.

The PEDAL jack lets you use a single switch to switch presets. This works fine if you have just a few presets to switch between. The Axe-Fx III, II XL(+), AX8 and FX8 have more than one PEDAL jack. You can assign one to increment presets and the other to decrement presets. You can use a PEDAL jack to switch scenes, see Scenes.
Axe-Fx II, AX8 and FX8:
- Connect a single (pref. momentary) switch to the rear.
- Set it to Momentary in I/O.
- Set PRESET INCR to ON.
- Set the range of presets that the switch can switch between through the Start/End parameter. Or set these to the same preset, to recall a specific preset.
Axe-Fx III:
This is configured in the Global Controllers menu.
Engage or bypass an effect
The PEDAL jack can be used to connect a switch to engage or bypass a specific effect. In I/O assign the effect block's CC to PEDAL.
Switch an effect between X/Y or switch channels
The PEDAL jack can be used to connect a switch and change an effect between X and Y or between channels. In I/O assign the effect block's X/Y CC or channel to PEDAL.
Troubleshooting
Zipper noise
If moving the expression pedal creates choppy sounds or zipper noise, increase the Damping parameter in the Modifier menu. source
Checking the ADC levels of the pedal ports
The Axe-Fx III lets you to check the ADC (Analog-to-Digital Converter) levels of the pedal ports (Utility menu).

AxeForLemur
AxeForLemur is a Lemur Template designed by David Sorlien to control the Axe-Fx. The Template runs on the Lemur APP by Liine, and connects wirelessly through a logical midi connection to the AxeFx.
This page is intended for users and developers of this template.
Usage
AxeForLemur is a JZML script, licensed by Creative Commons to be a non-commercial, free to use script. The script runs on IOS and Android devices with the Lemur Application from Liine. The Lemur Application communicates with the Axe-Fx either through direct MIDI connection, or through Wifi to a Host Computer, that is connected either through USB or MIDI to the Axe-Fx.
To configure an IOS/Android Patch Editor for the AxeFx:
- Purchase the Lemur App ( $20-$35 ) and install it on your Tablet or iPAD.
- Go to the Liine Website and register yourself as a user, then download, the Lemur Editor and Daemon Software.
- Connect your Tablet to your computer's IP network. Verify IP address, and ping your tablet to verify.
- Start the Lemur App on your Tablet or IPad.
- Download an AxeForLemur.jzml script. Current version is 3.08.
- On your PC run the LemurEditor and load the AxeForLemur.jzml script, Click Connect to send the script to your Tablet or IPAD.
- You should see the AxeForLemur Script on your IPAD, on the Default AMP page.
- If your AxeFx is connected to your PC/MAC through a USB cable, run the LIINE LEMUR DAEMON on your machine. This DEAMON will provide an IP Socket on the Network for MIDI and OSC communications from the IPAD to any MIDI devices on your PC/MAC.
- Within Lemur on your Tablet Open the Settings drop down list and select "More Settings...", Setup Midi Targets, From: and To:. You may need tap Add Target. You should see a list of network computers, with MIDI devices high lit. Choose AxeFx from the computer that is running the LEMUR DAEMON, for both "From: and "To:. If no devices show up, please verify the IPAD is connected to the IP network, and that the Lemur Daemon is running, and the AxeFX is turned on, and it is connected with USB or MIDI cable.
- On the Preset Select page of the AxeForLemur script, configure the midi settings to match your setup. Example, Column-A should Device should be set to AxeFxII or AxeFxXL+ etc, midi channel to '1' to match your MIDI settings, and Lemur target set to the Target within the Lemur Menu.
- Test by Tapping the Preset Up/Down.
- Troubleshooting can be a bit challenging and might require a bit of system debug and tweaking.
Design
Design background into key elements of the AxeToLemur script:
Axe For Lemur is a comprehensive Lemur script based in Quasi XML, Objector based C-Script with out pre-processor, structures, pointers etc. The Script is object based, and exists in the JazzInterface tab object AxeForLemur. Global references exist in this scope.
Design Initialization
Design Device Selection
The preset page (AxeForLemur/dlgProgChange/T1) Contains a Matrix of Midi settings for up to 4 target devices.
For each 'Target Device' The user can select and increment/decrement (cTargets/padUpDn) the following (cTargets/swSettings):
- Type : { AxeFx, AxeFx II, Gen Midi, No Bank, Eclipse } = aUser.cMidi.devtypes[ ]
- Display Offset : { 0 or 1 } = aUser.cMidi.dispoffset[ ]
- MIDI Channel : { 1 .. 16} = aUser.cMidi.chans[ ]
- Lemur Target : { 0.. 3 } = aUser.cMidi.targets[ ]
The user can select one of A,B,C, or D target devices; only one is active at a time.
The objective is to integrate AxeFxXL and AxeFxXL+ into the list of supported Device Types.
Since this template was last updated by David Sorlien, two new AxeFx devices have been created. The XL and XL+ have more or less the same SysEx protocols as the AxeFx ( subject to change ), but have New SysEx device ID codes. The following is a break down of work required to make AxeForLemur support other Fractal Audio Devices.
Essentially the T1/cTargets/swSettings is a 4 x 4 Switch matrix. Pressing a button will provide a 0..16 button index within the T1/cTargets/swSettings/x variable. Pressing one of the T1/cTargets/padUpDn will cause the selected T1/cTargets/swSettings/x indexed value to be Incremented/decremented. The padUpDn/tap() changesbutton matrix.
Add two more values to devtypes
change: aUser.cMidi.devtypes[a] = clamp(aUser.cMidi.devtypes[a]+1, 0, 4); aUser.cMidi.devtypes[a] = clamp(aUser.cMidi.devtypes[a]-1, 0, 4); to: aUser.cMidi.devtypes[a] = clamp(aUser.cMidi.devtypes[a]+1, 0, 6); aUser.cMidi.devtypes[a] = clamp(aUser.cMidi.devtypes[a]-1, 0, 6);
Add two more strings to button objet lablels
swSettings/updatelabels() for(i=0;i<4;i++){ if(aUser.cMidi.devtypes[i]==0) a[i] = 'AxeFX'; else if(aUser.cMidi.devtypes[i]==1) a[i] = 'AxeFX II'; else if(aUser.cMidi.devtypes[i]==2) a[i] = 'Gen MIDI'; else if(aUser.cMidi.devtypes[i]==3) a[i] = 'No Bank'; else if(aUser.cMidi.devtypes[i]==4) a[i] = 'Eclpse'; else if(aUser.cMidi.devtypes[i]==5) a[i] = 'AxeXL'; else if(aUser.cMidi.devtypes[i]==6) a[i] = 'AxeXL+'; }
Change Device ID's within SysEx messages to include devie ids { 6 and 7 }
<SCRIPT name="IsAxeSysex(msg)" .. if(msg[0]==0 && msg[1]==1 && msg[2]==0x74 && ( msg[3]<=3 || msg[3]==6 || msg[3]==7 ) ... else if(msg[3]==3) st = 'Axe-FX II'; else if(msg[3]==6) st = 'Axe-FX XL'; else if(msg[3]==7) st = 'Axe-FX XL+';
and change all hard coded device id's "0x74,3" with "0x74,6" or "0x74,7" in
SendSetParam(b, p, v) SendGetParam(b, p) SendGetPresetName() SendGetBypState() SendGetPresetNumber() SendLooperMonEn(en) SendGetSceneState() SendSetModifier(b, p, m, v) SendGetModifier(b, p, m) SendPlaceEffect(b, pos, flag) SendConnectEffect(p1, p2, f) SendSetPresetName(name) SynthMidiNoteOnIn(MIDI_ARGS) SendSavePatch(program, bank) SendGetCabName(cabnum)
It makes sense to define a class variable like cV.DevID, and make sure it is set on startup by the AxeFx device ID selected by the A,B,C,D device selector.
Design Modifiers
Modifiers provide a means to dynamically change a subset of the block parameters with automatic, and external functions. The AxeToLemur Script has a partial implementation of Modifiers. The AxeToLemur.pdf describes 'double tapping' the intended modify-able' control to enable modifier, but this doesn't appear to be within the implementation.
Within the 'control's bps[] array, for hw==0, element at index==6 is the Modifier number, if this value is >= 0, then the control should have modify-able values. This applies to 'bps' of sliders, custom buttons, muxed-sliders. If the 'control's bps[8] is set to 1, then there is an active modifier on the control.
It is assumed that 'double tapping' the 'Zoom' button will enable a RED "MOD" feature on the Zoom button. cS.DoubleTap() captures double tap event. This sets cV.dbltapzoom[2] = 1; A parameter that is 'Modify-able' has a Green 'txt' value.
As of 3.08, the repainting logic within the APP did not support GREEN 'txt' labels.
cS.psmxfdr(obj, p, p, m, t), and cS.psmxcb(obj,b,p,m,t) used to set/map a 'muxed fader' to an AxeFx control. This function also sets the colour of the text of a control
Notes:
ResetModifierText(..), called when changing pages in Lemur, to clear out cV.modlistlast
(cV.rState==5) modifiers are being queried SendGetModifier(..)
(cV.rState==6) modifiers are being queried SendGetModifier(mbps[hw], mbps[hw+6], a[i]); response in HandleModifierValMsg(msg), calls UpdateModifier(b, p, m, v);
(cV.rState==7) modifiers are being reset SendSetModifier(..)
buildModCtlList() saves cV.modlist[] to cV.modlistlast[], iterates through all objects in cMain. To find build a cV.modlist[] of modifyable parameters within objects that 1. contain a bps[], 2. are in a visible block, 3. the block is active in the preset, the bps[6] is >= 0. cV.dbltapzoom[] is filled with same array of objects
cS.DoubleTap() appears to be implemented to open a Modifier Dialog: dlgModifiers.showme(1); but it is not called within the Script. This function will trigger a 'DoEveryFrame' midi query of the Modifier setting.
3.09 TODO List:
1. confirm all modifier indexes on Fractal Parameters
2. call cS.DoubleTap() when Zoom == MOD and a modifyable control is Tapped.
3. verify control's txt value is rendered RED when control modified control is active (previously engaged, polled through DoEveryFrame())

Objects
Major AxeForLemur Objects:
aUser
User specific settings, like favorite presets, midi channel. These can be persistent if the user re-saves the script after mondifications are made through the script itself. Global midi CC's are stored in gen1.cc*
Querying : set to 1 during referesh, most likely to prevent re-triggering
aUser.cMidi.gen2 :: MIDI CC # numbers for different MIDI CC parameters
..scenescc[0] : MIDI CC # number for 'scene select'
cMain
User interface for Axe-Fx blocks.
cMain contains UI design and configuration for each Block (pair) Tab within AxeForLemur script
IntState3(..) macro, configures button labels within the UI interface. Typically these buttons are for Block instance selection, but some are for selecting other aspects of each' block Tab.
Each AxeForLemur Block Tab contains multiple containers, one for each UI element. These containers more or less contain a symetrical set of attributes, functions and UI controls that allow for support from a common set of functions (else where in the code).
Each UI Element contains: bps: Midi / UI control structure ctl: the lemur screen object x : Primary value for this control z : ??? txt: A screen description of the parameter. Example ('volume') txtval: text object on screen to describe the object parameter value. Example (0..127) Optional: cbDlg: a pop up dialog object x : value for the selected value of the dialog tap(..) : function called to initialize the dialog
When a control changes a 'magic' must be called to send the ctl's value to the bps[..] defined midi destination
cS
Common Scripting Object.
Common Script Object Container
addRefreshParam( b, p) : Adds a parameter to one of:

Development Tools
firstobject XML Editor Application. This is a light weight free XML editor that doesnt get confused by the Lemur script. The Editor has a good dual view ( one view is an XML object tree, the other side is the pure text. Using F7 allows you to sync between the two.
KDIFF3 http://kdiff3.sourceforge.net Since the AxeForLemur is a large monolithic text file, having a good DIFF tool allows you to see the changes LemurEditor and text editors have applied to your file. The LemurEditor does some strange things to this template when it is edited, the preference is to make clean edits with FirstObject Editor, and not use the Lemur Editor directly, as it has a habit of changing many unintended parameters throughout the script.
SVN or Git are good tools to manage progressive changes to the script.
