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. TC-Data takes the multi-touch controllers from TC-11 and opens them up to any external software.

The JAX DYNAMICS : Compressor is a single band dynamics audio processor and supports different stereo operation modi (like independent stereo, linked stereo, independent mid/side and linked mid/side processing) and has a parallel processing option (mix) too. The JAX Compressor is a dynamics processor in AudioUnit (AUv3) format. The audio unit itself (an app extension) is embedded into a small demo app. This is required for app distribution on Apple platforms. Installing the app will make the audio unit available for system wide usage with audio unit hosts (music apps), which support loading 3rd party app extensions in AUv3 format. There is a manual for our Dynamics Series Basic located at : https://audio.digitster.com/jax-dynamics-compressor A basic demonstration video for the dynamics series can be seen here : https://youtu.be/hOwM1t6jYes?si=gqlpp6oQRXtUuj8V This app is truly 'universal', meaning, unit is available for : - MacOS (Silicon) - iOS (iPhone) - iPadOS (iPads) - visionOS (Apple Vision Pro) Please note, that AudioUnits (AUv3) require a dedicated supporting host application to perform.

Verdict
The clearest difference is price: JAX DYNAMICS at $4.99 against TC's $19.99. JAX DYNAMICS also leads on review sentiment (100% vs 89%) and iOS requirement (14.0 vs 16.0). TC's advantage is rating (4.6 vs 3.7) and ratings volume (14 vs 3). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
TC costs $19.99 and JAX DYNAMICS $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
TC holds the better App Store score, 4.6 against 3.7. Both are backed by a comparable volume of ratings — 14 and 3 respectively. Written reviews complicate that: 89% of TC's written reviews are positive against 100% of JAX DYNAMICS's, so the app with the better star average is not the one people write more warmly about.
TC ships an update every 5 weeks, JAX DYNAMICS every 2 months. Both last shipped on October 24, 2026.
