About the FM3

Introduction

Product announcement:

Meet the New FM3 Amp Modeler/FX Processor

Now you can get Fractal Audio’s industry-leading amp and cab modeling, plus a suite of stompbox and studio effects, a powerful foot controller, 4×4 USB audio — and more — all in a compact, rugged, all-in-one, floor unit designed for the studio or stage.

Legendary Amp Modeling and Speaker Simulation plus a Suite of Incredible Stompbox and Studio Effects

The FM3 features our latest ARES Amp Modeling—a technology developed by Fractal Audio for the award-winning Axe-Fx III. It captures the sound — and the equally important feel — of real tube amps, with 265+ models offering an impressive range of clean tones, elusive “edge of breakup”, and everything from warm, touch-sensitive overdrive to face-melting modern distortion.

The FM3 also includes the entire speaker cab impulse response (“IR”) collection from the Axe-Fx III, with a stunning 2,200+ “Factory” choices and 1,024 “User” locations to store custom sounds from free or commercial producers.

As a multi-effects unit, the FM3 truly excels. It includes a superb selection of Fractal Audio’s state-of-the-art effect algorithms. All of the essentials and many exciting innovations are on board: dazzling drive pedals, dozens of delays, reverbs, compressors, EQs, phasers, flangers and other modulation effects, a looper, and much more.

Impressive USB Audio Capabilities — Playback, Record, Re-Amp

With a USB connection to a Mac or PC, the FM3 works as an extremely high quality 4×4 audio interface for playback, recording, and re-amping. This lets the FM3 double as the hub of a portable recording studio.

USB channels are mapped for maximum ease of use. For example, to record the processed stereo output of the FM3, just record inputs 1 and 2 in the computer. Computer inputs 3 and 4 can be used to capture a DI, or to record input 2 L+R in stereo.

Computer playback is also easy and flexible. For studio work, you can mix a project and the FM3 to a single pair of connected monitors and transmit a separate DI to the FM3 for re-amping. For live performances, you can route the stereo FM3 and stereo backing tracks to different stereo outputs.

USB also allows 2-way communication between the FM3 and its companion software applications, FM3-Edit and Fractal-Bot.

A Rugged Floor Unit

The FM3 is housed in a durable steel chassis with protective endcaps designed to withstand the rigors of touring.

Three onboard footswitches – each with variable-color LED ring and mini LCD display — provide both tap and hold functions, which can be customized to do different things on eight different switch “layouts.” The new “Views” feature multiplies the power of layouts, in effect creating a virtual 12-button controller with a 3-button footprint.

In addition, a FASLINK II port allows the FM3 to be connected with up to two Fractal Audio FC-12 or FC-6 foot controllers, providing an exciting array of extended control options.

While designed as a floor unit, the FM3 features an intuitive hands-on interface with the same full-color display and familiar, easy-to-use front panel controls found on the Axe-Fx III.

The unit is powered by a 3-Core “Griffin” DSP with one ARM and two SHARC+ cores providing superior power in a compact format. A dedicated graphics processor allows the main DSPs to be focused on critical audio tasks

Platform

"The Axe-Fx III, FM3 and the other products in development all use the "Ares" architecture. This is a portable client-server architecture that allows easy porting of effects and models between hardware platforms. When we ported the Axe-Fx III models to the FM3 it involved nothing more than copying the file. We created the Ares architecture three years ago and all new products use it. It's a comprehensive hardware and software paradigm that allows any number of clients to communicate with a DSP server. The architecture supports multiple DSP cores. Clients can be located on the same core, a different core on the same IC, a different IC on the same board or on completely different hardware, i.e. an editor running on a PC or a foot controller. For example on the FM3 the UI is a client running on the ARM core. The Ares architecture is even processor agnostic. The Axe-Fx III uses TI DSPs while the FM3 uses Analog Devices. The Ares architecture was a huge undertaking with the ultimate goal of faster product development and easy synchronization of multiple product lines. It allows me to work on algorithms and new models and the engineers can then easily port those to the other products." source

Manufacturing

"There's only so much heat you can dissipate in a small chassis. Add to that the requirement for harsh environments (outside, on a hot day in direct sun) and you have to be careful. There actually is a fan in the unit but it's controlled by a thermostat and under normal conditions it doesn't run. Reliability is paramount in a product like this. You can't have it shutting down during a performance." source
"The main board is roughly the size of the base and is filled with components." source
"While the audio path isn't identical to an Axe-Fx III the quality of the path and components is comparable." source
(Does the FM3 offer same or better audio path quality (converters-secret sauce-noise) compared to Ax8?) "Better." source

Processing

The FM3 is powered by a 3-Core “Griffin” DSP with one ARM and two SHARC+ cores providing superior power in a compact format. The dedicated graphics processor allows the main DSPs to be focused on critical audio tasks. Cab modeling runs in an accelerator. Amp modeling runs on the 2nd core DSP.

"The processing power of an FM-3 is roughly the same as an AX-8." source
"It's not nearly as powerful as an Axe-Fx III but it's a cool little unit." source
"The FM3 is not as powerful as an Axe-Fx III. The Axe-Fx III has at least four times the processing power." source
"Uses an SC587. The SHARC+ core has essentially the same MFLOPs as the SHARC. The overall processing power is greater than an AX-8 because of the ARM which offloads all the housekeeping stuff, USB, etc." source
”The FM3's CPU utilization meters are normalized so that 100% represents the amount of the CPU that can be allocated to audio processing. So you can go right up to 100%. However, if you ever cross 100% things will get shut off without your consent so you still need to be careful.” source
(comparing the amp modeling to the Axe-Fx III) "They are the same quality. Certain features were removed to allow the algorithms to run including the bias tremolo, input dynamics processing, and several other inauthentic enhancements." source
"We removed all the superfluous stuff (bias tremolo, dynamic presence/depth, etc.) in order to get the core amp modeling to run on the slower processor." source
"The Axe-Fx III contains various algorithms that allow you to enhance the amp modeling that don't exist on a real amp. I.e. dynamic presence/depth, input dynamic processing, etc. These were removed to allow the core amp modeling to run on the lower-powered processor." source
(Cab block runs on CPU accelerator) "It's a CPU accelerator thing. A second Cab block would use a lot more than 3%." source
"FM3 CPU is normalized so it's tricky to get an apples to apples meter comparison with A3 for that reason among others." source
"FM3 has an additional core to handle UI/Midi/Footcontoller stuff so that freed up some CPU. Additionally a bunch of little optimizations you find while working in the code for a long time. 1% here, 1% there adds up." source
"(...) The DSP power makes it the second most powerful amp modeling product on the market behind only the Axe-Fx III. Adding another DSP would increase the price substantially. The increase would be more than the price of just the DSP since larger power supplies would be required, etc. This would price the unit above our target price." source
"The FM3 DSP is three cores and also supports floating-point, has dual DDR3 memory busses, hardware FFT and FIR accelerators, etc."source

"The USB outputs (IN Endpoints) are Output 1 L/R, Instrument In and Input 2 Left." source
"The USB-A connector is for a FLASH drive to import/ export presets. However it’s currently not working yet." source
“The USB-A port can be whatever we want but it requires writing drivers (or buying them and hooking them into the OS). If the demand is great enough we can look into these things. Peripheral drivers are a lot easier than host drivers and USB-A is host.” source
(Can it be controlled with a regular MIDI pedal) "Of course." source
"The MIDI runs at 5V."

Effects list

Click on the image below:

FM3 effects.jpg

"Due to the lesser processing power there are fewer instances of many effects, i.e. two instead of four. Channel counts are the same." source
"Only one amp block. (...) It does not have all of the Axe-Fx III effects but has the most important ones (no vocoder, etc.)." source
"We could potentially do two amp blocks but at reduced quality and I don't want to do that. Part of the problem with other modelers is that they don't oversample enough (and use single-precision in places where you need double-precision). Then you get complaints of artifacts and ear fatigue and all the other things associated with inadequate sample rate and word length. The vast majority of users only use one amp block so we wanted to make something with one very high quality "Ares" amp block." source
(Cab block runs on CPU accelerator) "It's a CPU accelerator thing. A second Cab block would use a lot more than 3%." source
(comparing the amp modeling to the Axe-Fx III) "They are the same quality. Certain features were removed to allow the algorithms to run including the bias tremolo, input dynamics processing, and several other inauthentic enhancements." source

Onboard switches

FM3-switches.png

Three onboard footswitches – each with variable-color LED ring and mini LCD display — provide both tap and hold functions, which can be customized to do stuff, using switch layouts and views, globally or pre-preset.

The switches can be programmed to:

  • switch presets
  • switch scenes
  • switch channels
  • switch layouts and views
  • turn effects on/off
  • perform utility tasks
  • etc.

For more information about the Tap and Hold functions, read this: Tap and Hold functions on FC controllers

External switches

The FM3 allows dual-button switches to be connected to each of its pedal ports.

These external switches can perform the same tasks as the onboard switches.

"Supports 2 pedals/switches." source
"You can plug in dual button footswitches into the pedal inputs." source
"External switches can do anything the "local" switches can." source
"Any button can be assigned to activate the tuner. source

Adding an FC controller

The FM3 can be expanded with up to two FC controllers.

FM-FC.png

"You can hook an FC-6/12 to it. So for small gigs/rehearsals use the FM-3 alone. For larger gigs connect an FC (or two)." source
"If anyone is curious the thought process was this:
  1. FM3 alone for rehearsals, small gigs.
  2. FM3 plus FC6/12 for larger gigs.
  3. Axe-Fx III plus FC6/12 for MSG. (Madison Square Garden)
Since the FC6/12 are "thin clients" you can exchange them with the Axe-Fx III and FM3 without having to do any programming." source
"FASLINK powers the first FC. FC setup is same as Axe-Fx III." source
