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!

DEVICE MOTION CONTROL:

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!

SYNTHESIS:

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.

### 2/5 — Currently Not Working

*2026-02-13*

Since the update crashes out upon opening.

### 1/5 — Still crashing

*2026-02-13*

UHG

### 5/5 — the only ipad synth

*2026-02-08*

I have spent years trying synthesizer apps on iPad. The vast majority of them are just terrible, because they don’t actually use the iPads’ strengths. Instead, they are content to reproduce on the screen, the dials and sliders and keys of physical synthesizer, creating a frustrating user experience

TC 11 is in a different dimension. It rethinks how to lay out the controls of the synthesizer from the perspective of a touchscreen it’s a beautiful and thoroughly deep experience.

### 3/5 — Great program but broken!

*2026-01-22*

Every time I open it up, it crashes. Black screen for a moment and then completely disappears. Please fix.

### 5/5 — This App Is Unbelievably Brilliant ⭐️

*2026-01-09*

For years I have wondered how did the band Ozric Tentacles create those lush electronic sounds….. I need wonder no more, those sounds are here in abundance, although not the original source, but 99% near enough.
This has to be my best purchase on the App Store. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

### 5/5 — Magnificent Sound App!

*2026-01-07*

This app is easily in the top 10 iOS audio apps ever. Probably the single most innovative and creative use of a touch screen for audio use since the advent of touch screens. Not only that, but the sound quality is phenomenal!

### 5/5 — Jewel of an app

*2026-01-05*

I can’t believe I’ve not really looked at this before. It properly utilises the iPad touchscreen format. I would put it alongside Samplr and Gestrument (for example) in this regard. It’s possible to make a remarkable range of sounds that will be very usable as tonal instruments, soundscapes, percussion and fx. Hats off to the developer!

### 5/5 — Please add new presets

*2025-08-08*

Please update : 
New sounds packs
Auv3
More controls on panel synth ..
Больше хочется контроля на панели синтезатора 
Новых звуков новых наборов и новых расширений 
plus Sequencer 
Thanks by your works!!

### 5/5 — Very truly

*2024-10-17*

Very truly just what I need in my adventurous life love the sound of this synth

### 5/5 — Der Wahnsinn für elektronische und „neue Musik „

*2024-01-17*

Die Klangästhetik von diesem Synthesizer ist unglaublich. Jeder kann den Spielen. Man kann in Improvisation einbauen, da man die Tonart leicht festlegen kann. Ein echter Gewinn Gerät und die Welt der Musik.
