Current release: v0.1.0 Alpha
Hardware MIDI Companion for Android and Windows
A lightweight companion application for hardware MIDI setups, featuring a visual transport monitor, drum pattern generator and melody composer.
GrooVoid was originally built as a simple visual MIDI transport for my own DAW-less hardware setup. As the project evolved, it grew into a companion application featuring a drum pattern generator, melody composer and several MIDI utilities.
- Visual MIDI Clock Transport
- Beat / Bar / Phrase Visualizer
- Drum Pattern Generator
- Melody Composer
- MIDI Monitor
- Standard MIDI IN / OUT
- Android
- Windows
GrooVoid communicates using standard MIDI messages.
Although it was originally developed around an Elektron Syntakt acting as the master clock, it should work with virtually any MIDI-compatible hardware or software.
Recommended platforms:
- Android tablets
- Windows
The application has been tested with my own hardware setup (Elektron Syntakt, Digitakt II, Behringer Edge, Spice and Pro-800), but should work with virtually any device supporting standard MIDI messages.
