7-channel MIDI Trigger Board designed for controlling relays, lights, drums, solenoids, and other 5V trigger-based devices from MIDI equipment.

This module converts MIDI note messages into seven independent 5V trigger outputs corresponding to notes A–G. Ideal for interactive installations, DIY electronic instruments, lighting control, percussion triggering, and experimental MIDI projects.

Use a MIDI keyboard, sequencer, drum machine, or DAW to trigger external hardware directly. For example, control multiple spotlights from a MIDI controller keyboard or trigger external percussion circuits from a sequencer.
