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!

Holy sh**


Quite possibly the most interesting iOS synth available. Every penny is worth it.



Audiobus! I have been using synthesizers for over 20 years. Both analog and digital. This app is great sounding with more depth than anything in the app store. It looks cool when playing with it. With that being said, this app is confusing. It is not as easy as most apps. I own 100 music creation and sequencing apps and this is among the hardest to really dig into. It is worth the time if you want to learn it. This is an incredible sound making machine. Easily the best sounding synth app there is.
The developer of this app is top notch and quite happy to hear from users. I have emailed him just to say how happy I am with this synth. He truly seems happy to hear from people. He seems like the type of person who would love to hang out with musicians just to see what they can do with his app.
I purchased this app on Christmas Day 2011. It is now July 22, 2012. You could easily say the honeymoon is over. I have grown sick of so many sound creation toys in way less time than this.
This app is the real deal people.



If you're looking for a fine synth that blends nicely and fits the mold of typical synth apps in terms of sound and function? Then look elsewhere! TC-11 is anything but typical. You're probably not going to play conventional melodies on this synth, or look to play exact chords, or attempt to duplicate performances. This is a synth with a different agenda in mind. It focuses on expression and is quite nuanced in how the player is touching and holding the ipad. It's truly an ipad instrument vs. a synth adapted to the ipad. TC-11 makes use of the entire screen as its playing area. It seems that if you're into more avant garde electronic music, or experimental music of any sort than this synth is what you're looking for. The sounds are spectacular, and many stand out in a mix for their unusual changing timbers, which is good for transitions. Not many sounds on this synth are for blending. You will want to get this synth if you're making more unusual music, or want to be inspired by a new approach to the app screen.
