| − | ==About MIDI System Exclusive (SysEx) messages==
| + | If you're a MIDI expert, you can use SysEx messages (MIDI System Exclusive) to control Fractal Audio devices. |
| − | * If you're a MIDI expert, you can use SysEx messages (MIDI System Exclusive) to control the Axe-Fx II.
| |
| − | * To learn more about MIDI, read [http://en.wikipedia.org/wiki/MIDI this article].

| | | | |
| − | ==SysEx messages for Ultra==
| + | [http://electronicmusic.wikia.com/wiki/System_exclusive Learn more about SysEx] |
| − | * Ultra-specific SysEx information has been accurately acquired and organized by forum member GM Arts: [http://www.gmarts.org/html/axefx_ultra_sysex_1005.html here].
| |
| − | * Information about SysEx commands for retrieving Preset/Effect bypass states is [http://forum.fractalaudio.com/other-midi-controllers/39161-using-sysex-recall-present-effect-bypass-status-info-available.html here].

| − | ==SysEx messages for Axe-Fx II==
| + | [http://forum.fractalaudio.com/threads/sysex-0x02-midi_get_parameter.123480/ Discussion about Fractal Audio's SysEx implementation] |
| − | * Many Axe-Fx II SysEx messages are similar to Standard/Ultra messages documented [http://wiki.fractalaudio.com/index.php?title=Axe-Fx_SysEx_Documentation here].
| |
| − | * Model ID is 3.
| |
| − | * All messages must be sent with checksums.
| |
| − | * Responses for some key messages are different. Information about SysEx commands for retrieving Preset names and Preset/Effect bypass states is [http://forum.fractalaudio.com/other-midi-controllers/44824-what-sysex-message-get_preset_name-axe2.html here].
| |
| − | * All Axe-Fx II SysEx messages have the same header as follows:

| − | ==Calculating the SysEx checksum for the Axe-FX II==
| |
| − | * As mentioned above, the Axe-FX II units require a checksum to be added to the end of the SysEx string that is sent to it (before the terminating F7 byte) as a verification step.
| |
| − | * In order to calculate the checksum, you basically have to XOR every byte from the start of the SysEx message, up to the character BEFORE the terminating F7 byte. For example, to send the following SysEx message (to fetch a preset name):
| |
| − | | |
| − | F0 00 01 74 03 0F F7
| |
| − | | |
| − | We would have to XOR all the byte values from the starting 'F0' to the '0F' which is the second last byte:
| |
| − | | |
| − | 0xF0 ^ 0x00 ^ 0x01 ^ 0x74 ^ 0x03 ^ 0x0F = '''0x89'''
| |
| − | | |
| − | Then, we would need to strip the leftmost bit from the result (by ANDing it to 0x7F):
| |
| − | | |
| − | 0x89 && 0x7F = '''0x09'''
| |
| − | | |
| − | And, we add this byte (actually, a septet now) to the end of the SysEx string, BEFORE the terminating F7:
| |
| − | | |
| − | F0 00 01 74 03 0F '''09''' F7
| |
| − | | |
| − | Obviously, in a 'static' SysEx message like above, you do not have to recalculate the checksum each time as it will always be '09' as the rest of the message does not change, but if you are sending a SysEx string to change a parameter value etc. then you will have to calculate the checksum on the fly as byte values towards the end of the SysEx string will be different each time.
| |
| − | | |
| − | ==Obtaining Parameter Values via SysEx Messages==
| |
| − | | |
| − | The old Standard/Ultra devices used to store the parameter values on *most* knobs as 0-254. This was split into two bytes, XX YY where XX was the lowest 4 bits of the value, and YY was the highest 4 bits. Pretty simple.
| |
| − | | |
| − | The new Axe-II now has more granular control over *most* knobs, with the values going from 0-65534. This requires a full 16 bits to store. The problem is that the MIDI specifications means you can only transmit values using 7 bits as the highest bit of each byte must be a zero.
| |
| − | | |
| − | To get around this, the Axe-II uses THREE bytes to transmit the values XX YY ZZ where XX is the lowest 7 bits of the data, YY is the 8th to the 14th bit of the data, and ZZ is the remaining top two bits of the data.
| |
| − | | |
| − | So, if you had the value 52421 on a knob, then this would be represented by the 16 bits: 1100110011000101
| |
| − | | |
| − | If you split this into segments of length 2/7/7 to store in ZZ/YY/XX: 11 0011001 1000101
| |
| − | | |
| − | So XX gets the last segment: 01000101
| |
| − | And YY gets the middle segment: 00011001
| |
| − | And ZZ gets the first segment: 00000011
| |
| − | | |
| − | You will also have to back-calculate the respective knob values to the 16 bit values. For example, a knob that goes from 0 - 10, 0 would of course be 0, but 10 would be 65534. From there, you would work out that 5 is 32767 and 7 would be about 45871 etc.
