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.
