Filtatron is a realtime audio filter and effects engine.

Use sound from sound sources:
- Line/microphone input
- Sampler
- Built-in oscillator

Import any song on your iDevice into the Sampler.

Run a sound through a virtual version of the famous Moog filter with a little (or a lot) of filter modulation, delay, and overdrive to create your own musical statement.

Multi-touch X-Y pads provide highly tweakable performance control for live use.

NEW: Switch Pad to "Pitch Lock" mode to play chromatic scales.


OSCILLATOR – A high-resolution, alias-free DSP oscillator with sawtooth and square waveforms, adjustable frequency from 0.3 Hz to 2kHz.

FX MODULES – Amp provides warm, smooth overdrive with feedback control. Delay can be modulated by its own LFO (with rate and depth controls) and delay time is smoothly interpolated for analog-style delay time tweaks.

LFO – Five waveforms: sine, ramp, sawtooth, square, sample & hold, with crossfade and morph between adjacent LFO shapes.

ENVELOPE FOLLOWER – Uses the volume envelope of sound inputs to sweep the filter, with controls for amount and speed.

PRESETS - Filtatron comes loaded with edgy presets to kick-start your sound.

RECORD AND PLAYBACK – All audio processed in stereo, 16bit, 44.1kHz resolution. Filtatron will record samples up to 10MB.

FILE SHARING – Easily move audio files back and forth between the Filtatron and your computer. Built-in email function allows sharing presets with your Filtatron bandmates. Samples can also directly be shared on SoundCloud.

MIDI MAPPING - Almost every parameter can be controlled over MIDI. Use hardware controllers or external sequencers to control Filtatron remotely. Check the MIDI menu on the 'About' page.

Life’s a rough mix, filter it!

Still love it


Yes like others I got this way back when. Yes it’s still an awesome tool and has a lot of ability to make otherworldly sounds from my silly little iPhone. I do wish I could plug in a midi keyboard to control the loops like Animoog, but the real use here is of course with the x-y pads.



just needed a simple filter, doesn’t let me take the lfo out waste of money. also when the filter of the mix is on it kills the highs of the mix, the filter is also very weak. was using this through my dj mixer with an irig.

Let me preface this minirant by saying I have owned three '80s-era Moog synths. My comments are these: 1) There is a learning curve with using an analog (in this case modeling) synth. Due to the wide range of control the Moog people give the users of their products, it is possible to have settings which are silent or very quiet, or just don't sound very pleasing. Be patient with this, as it takes some time to find the sweet spots. 2) For those who complained about the expense of this app, consider this: up to this point you couldn't even buy a t-shirt with the Moog logo on it for $5. Moog ownership has been a cost-restrictive elite club for enthusiasts up until last week. I cannot believe they are selling this much wonderful Moog sound for that price. I have paid a bit more for much lesser apps. And have not paid less that $600 for even an "entry-level" Moog that needed repair. This is a steal, has the X-Y pads, you are able to run other sounds through the filters and modulate them, it has a built-in delay, oodles of controls, and some pretty good patches to start you off. Yes, a keyboard would be a nice upgrade, but for $5 this is by far the best synth for Iphone/Ipod and sounds better than many dedicated synthesizers. Unbelievable!
