MULTI-TOUCH CONTROL:

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.

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!

## TC-11 Reviews in United States

### ***** "Very truly"
Very truly just what I need in my adventurous life love the sound of this synth
-- Speller Littlewing, 2024-10-17

### ****- "Please interface with the outside world!"
This is a very cool concept but having no midi or ableton sync limits it’s use.
Also being able to import samples and waveforms would make this a monster app.
-- Samsjamz, 2023-11-11

### ***** "Coolest app on the app store"
This app isn't just a great synth, it's a great example of what an iOS app can be!
-- ryfar, 2023-08-02

### ***** "Esteem Boosting!"
I feel like an artistic savant while playing it!
-- kk100, 2022-05-12

### ***** "Just Brilliant"
It's hard to describe how well designed this instrumental piece of art is ...
Beautiful Depth ...  just need to figure out how to implement it 😃
-- El Gennaro, 2022-02-20

### ***** "Having a blast"
Just discovered the 4 patches at once. Way cool.
-- MN.Mike, 2021-03-17

### ***** "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.
Dave
-- Hamachi chop chop, 2020-01-27

### ***** "Playful and inspiring"
Nice work to the devs!
-- mike-tucker, 2020-01-19

### ***** "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!
-- (iOSTRAKON), 2019-10-04

### ***** "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.
-- therealriverrat, 2018-11-25

### ****- "Amazing app, but could be even more amazing."
I just started using iPad synths along with other hardware and plugin based synths, and this one is a stand out. Amazing. My only issue with it is that it could even be a bit more useful if it would integrate with the rest of my studio via MIDI. By that I mean, accepting a MIDI clock sync from my DAW and other note and CC information so that I could send it a sequence while I’m using the interface to manipulate the other parameters in real time. Also, if it spit out MIDI note and CC info so that performances could be recorded, edited and then played back... again, a pro feature but would really take this thing to the next level and make it a must have in any electronic music production studio.
-- zerocrossing, 2018-02-24

### ***** "Holy sh**"
Quite possibly the most interesting iOS synth available. Every penny is worth it.
-- crsko, 2018-02-19

### ***** "Great App-Nothing else like it!"
Also really loving the AudioShare update. Screw AudioCopy; life is too short to deal with its hassles.
-- Ben Efitofadoubt, 2017-05-10

### ***** "Fantastic Synth / Soundscape app !"
Still learning what can be done with it ... So far, it, I have found is fantastic for evolving (you control) Ambient atmospherics
-- AshFallenBrightly, 2017-01-10

### ***** "Excellent Synth"
One of my favorite ways to make music!
-- Hang 2, 2016-10-09

### ***** "Insanely great!"
I just love this! An intuitive, beautiful instrument
-- tbeckett, 2016-06-08

### ***** "Feature Full Update"
One of the few music apps that actually takes advantage of your device's touch surface and sensors rather than rehashing some analog instrument. The sound quality is superb. You can build your own patches or use one of the many excellent patches in the app. It plays well with others including IAA and Audiobus. Works on phones now too.

Being able to have multiple patches to play at the same time really makes me want to finger my surfaces.
-- polarpaul, 2016-06-08

### ***** "A uniquely iPad experience"
TC-11 takes full advantage of the touch surface of the iPad, and does things no other iOS synth can do.

A powerhouse of a synth, with depth rarely seen elsewhere, it's a must if you've got the guts to tackle it.

The 2.0 updates have made programming much more user-friendly.
-- Sean Garland, 2016-05-02

### ***** "Insanely fun And useful"
This synth is unique and fun to play.
-- Hydra vein, 2016-04-15

### ***** "learning"
Once this synth app "clicks" and you realize what you have in front of you, it just might be your new god.
-- myelectron, 2016-02-26
