Axon 2 is a drum synth driven by artificial intelligence. (Well, "intelligence" might be a strong word. Artificial something-or-other.) An experimental instrument, Axon uses a modified artificial neural network as a sequencer, and features seven FM-based percussion voices, that are really a single 18-operator FM voice.

If that sounds weird, you ain't seen nothing yet. It is surprisingly intuitive once you get the knack of it, and is capable of all-new, complex rhythms that repeat in surprising ways. It often gets referenced as a "random sequence generator," but there is nothing random in Axon; it is entirely determinative.

The sequencer features seven "neurons" that trigger a voice and send a pulse when they have received a predetermined number of pulses. You can wire the output of any neuron to the input of any other (with built-in loop detection to prevent runaway feedback), and in this manner pre-program the artificial neural network without having to go through a "learning" phase.

The seven individual drum voices, each triggered by its attendant neuron, are 2-operator FM voices in a configuration to best make percussion sounds, with additional FM and AM busses that all voices send to and receive from. Each voice has a HPF, distortion circuit, and white noise generator to provide a full range of percussion-oriented voicing individually, while interacting with each other in new and unique ways.


• Artificial Neural Network sequencer features seven neurons, and is easily programmed to create strange new repeating rhythms.

• Seven FM percussion voices that also buss together to create a single monolithic complex percussion synthesizer.

• Full mixer with pan, level, mute, and solo on each voice.

• Built-in stereo delay with X/Y pad control over feedback and filter frequency, for live playability.

• MIDI input, including Bluetooth MIDI, for driving Axon from DAW and hardware sequencers, and Virtual MIDI Output (standalone only) for driving other software with the Axon sequencer.

• Inter-App Audio, including transport synchronization, in standalone mode.

• Internal transport for non-synchronized playback.

• Resizable vector-based user interface.

• Drawn reciprocation dingle arm to reduce sinusoidal depleneration.

• XML-based cross-platform, human-readable preset system, with copy/paste, for easy transferring of your own presets and third-party offerings.

Please Note: This application will work fine on an iPad Mini, but the user interface may be difficult to use due to the size.

What's New

Version 2.0.7

MIDI output of the standalone version has been rewritten to deal with the "MIDI Out Bug" often talked about. As far as we can tell, it is now fine. Also, the MIDI out has been changed so that the MIDI note triggered by the voice reflects the pitch setting of that voice. i.e. if the Axon voice 1 pitch setting is A sharp 1, the MIDI note it triggers will be A sharp 1.

Very unique idm glitch drums

Oceans in space

Amazing fm synthesis that is very different to me in the way it unifies all the synth drum tones magically somehow. Something about the 1 osc mainframe brain or network? The sounds can be so strange yet clear and trippy. It reminds me of 'different drummer app', in that it seems so deep and unique with a life all its own. This sick drum synth app and their other (pure synth) app 'phosphor' have solidified their brilliance. I this company and can sense their rather mad hatter time warping sensibilities. Axon technology seems to be based on a psyonic Crystalized core fragment spinning percussively inside with non-organically digitalized fractal sound frames. Then you realize that there is midi working well and you are on the moon.

Too difficult....


This is probably the most unintuitive and difficult drum app I’ve ever bought. If there’s any app that should come with a manual, this one should but it doesn’t. I’ve spent over an hour trying to produce more than one sound and still don’t know where this app is coming from. Aside from the included presets , I find this app a complete killer of creativity, making music just should not be this difficult. I have ever iOS app Audio Damage put out, but this is a major killjoy for me. Sorry, but I would not recommend this app to anyone.


doug funnie

Is the only Audio Damage app that has been plagued by consistent problems. The MIDI was fixed, but AU in AUM and apeMatrix crashes within 15 seconds of start time, and using the IAA ...well it just goes haywire when trying to program sounds.

It's a lot of fun, but beware functionality on this one. Very unlike the company to put out faulty stuff.
