There are no on-screen knobs, keys, or sliders to fiddle with; all synthesis is driven by your multi-touch performance. Touch relationships like distances / angles / timings perform all the controller functions. It's just you and the full screen multi-touch performance area.

EVERY synthesis parameter can be controlled by ANY multi-touch controller. The patch possibilities are limitless!


Use the iPad's accelerometer, gyroscope, and even the compass to attack your synthesis patch! Tilt and move the iPad to change any filter, effect, or module. You can create real vibrato by moving the iPad during performance, or change the speed of a sequencer by tilting forward and backward!


TC-11 has 8 voice polyphony for full, real-time synthesis. The audio engine has been highly optimized to deliver crisp, responsive performance. Choose from 22 oscillator waveforms, 3 oscillator types, 3 filter types, 4 unique effects, amplitude modulation, and panning control.

Fully programmable AHDSR, LFO, and sequencer modules make TC-11 the most capable iOS synthesizer in the world.

Use TC-11 in your band during live performances. Add TC-11 into your laptop orchestra. Experiment and create with the next evolution of synthesizer control!

The best iOS synth for me!

I have been playing synthesizers since 1975, lots of hardware and software ones.
TC-11 is by far, my favorite on the iPad.

It takes full advantage of all the iPad’s unique capabilities.
With the different play screen options, that use multitouch, and directional/motion sensors to control the various synthesis parameters, there is nothing else like it.

Along with the unique user interface, it has the best synth engine to use with it.

To get the most out of it, read the comprehensive user guide, that you can download from inside the app, or from the developers website.

It comes with a lot of great presets, that make a wide variety of sounds, so you can start enjoying it right away.
Working good with my original iPad Air, and my 12.9” iPad Pro.

Without a doubt, the best money I ever spent on an iPad synth app.

Thanks very much Kevin, and please keep it current, with updates as long as you can.
Best wishes.

Amazing! Just one thing.

I just got this app and absolutely love it! It’s so much fun to play and sounds amazing. There is just one thing that is missing though, the ability to record motions. I really believe that feature would bring it up to the next level.


Love the noise but....

Experiencing a lot of crashes within AUM after the 13.1 update. Working on iPad Air 2. Hope to see this fixed soon, thanks!
