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.

Descent is a real-time granular effect that captures incoming audio, breaks it into tiny grains, and scatters them across time and pitch. The result: everything from subtle thickening and rhythmic delays to vast frozen soundscapes and shimmering pitch-shifted clouds. GRANULAR ENGINE Control up to 50 simultaneous grains with independent settings for duration, overlap, and envelope shape. Play grains forward, reverse, or randomly mixed for tape-style effects, reverse swells, and glitchy textures. PITCH SHIFTING WITH QUANTIZATION Transpose from -24 to +24 semitones. Lock pitch shifts to specific intervals—octaves, fifths, or any chromatic combination—for harmonically correct shimmer and transposition effects. SIX-AXIS RANDOMIZATION Independently randomize pitch, pan, position, amplitude, duration, and grain count. Dial in subtle organic movement or push into complete textural chaos. DIFFUSION AND FEEDBACK High-feedback mode with a diffusion control transforms delays into lush, reverb-like washes that never get harsh or run away from you. TEMPO SYNC Lock grain timing to your session's tempo or let textures evolve freely in untethered mode. 35 FACTORY PRESETS Covering shimmers, delays, reverbs, pitch effects, and experimental sound design. Cross-platform XML presets are compatible across all Audio Damage plugin formats and operating systems. SOUND DESIGN IDEAS Add subtle depth with a few long grains and minimal randomization Create rhythmic delays with short, quantized grains at high feedback Build infinite sustain pads by freezing audio with high grain count and overlap Craft shimmer effects by quantizing pitch to octaves and fifths Transform vocals into ethereal textures with diffusion and wide panning AUv3 compatible. Runs standalone or hosted in AUM, ApeMatrix, Audiobus, Cubasis, GarageBand, and other AUv3 hosts on iOS 13 or newer. From Audio Damage—making creative software for discerning musicians since 2002.

ReceptionRating · Positive reviews · Number of ratings

Descent Granulator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: TC has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of TC's written reviews are positive against 0% of Descent Granulator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TC ships an update every 5 weeks, Descent Granulator every 2 months. The most recent releases landed on October 2, 2026 and October 14, 2026 respectively.
