midiphy MatriX - Mechanical Grid
A Canvas for your Sequences

Two bidirectional MIDI ports and a dedicated button to switch between them.

Dedicated navigation joystick for moving selections, scrolling through clips/sequences and more!

High-performance STM32F4 MCU using RTOS as a software base for a responsive and fluid user experience.

Full midiphy SEQ v4+ and MIDIbox SEQ v4 support - compatible with existing BLM 16x16+X protocol.
