TC-Data is a MIDI and OSC (Open Sound Control) controller that sends messages to other apps and hardware. The app has over 300 multi-touch and device motion controllers and triggers which can be assigned to any MIDI or OSC message output. TC-Data is not a synthesizer, but it is designed to control them, plus any other MIDI or OSC software. With TC-Data, you create your own interface to send the gestures and touch motions you choose. There are no sliders, knobs, or buttons. TC-Data directly connects your touch movements to the outputs you program. Create MIDI notes, CC, pitch bend, patch change, and aftertouch messages with totally unique multi-touch controllers. Or send values directly to your program of choice via OSC, where you can build your own project using TC-Data as the front-end. Features • MIDI over Bluetooth (Mac) • Inter-app control via CoreMIDI • OSC over Wi-Fi (Mac) • Support for external MIDI interfaces • MIDI input passthrough • Virtual MIDI output • Fully assignable touch controllers • Gyroscope and accelerometer motion control • 300+ controllers and triggers • 14-bit MIDI CC support TC-Data is based on TC-11, an all-in-one multi-touch synthesizer.

Holding the simplicity of a rare 1978 instrument and carrying its raw heritage to you, it turns your device into a pocket beat making companion. I believe that designing a pure interface, simply displaying your machine without any distraction, was the best way to reflect the spirit of the period it was born. Characteristics : - 8 Original high quality double-samples - 16 preset patterns - 3 Selective instrument deletion modes - Commutable « Spacedrum » instrument - Full machine state auto-save - Background audio playback enabled - Audiobus V3 - InterApp audio Bonuses accessible in your device settings : - Additionnal LED display for the tempo and the volume - Pattern selection LED indicators - Alternative « Rock » drum kit with integrated effects - Built-in intruments effects : « Stereo pan » and « Jungle tune » - Built-in audio effects : « Equalizer » and « Distortion » - Built-in global effects : « Delay » and « Reverb » - Mute any instrument I hope you will enjoy it as much as I love it ;-)

Verdict
The clearest difference is review sentiment: TC at 89% against DRM's 38%. TC also leads on rating (4.6 vs 3.7) and update cadence (every 5 weeks vs every 7 months). DRM's advantage is price ($0.99 vs $19.99) and iOS requirement (12.0 vs 16.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
