Expander · 6 HP
Midi-IO Expander
MIDI in and out for the NerdSEQ, plus a Sega Genesis gamepad port for driving the sequencer from a D-pad instead of the front panel.
The standard way to get MIDI onto the NerdSEQ bus: a MIDI in and a MIDI out, for sequencing external gear or recording MIDI in from a keyboard or controller. The gamepad port doubles as a second way to navigate and edit — start, stop, cursor and note entry — for anyone who would rather use thumbs than the six front-panel buttons.
- MIDI in and MIDI out.
- MIDI recording, straight into a pattern.
- Sega Genesis gamepad port for navigation and note entry.
- Polyphonic sequencing over several channels.
Not a standalone product — it works only with the NerdSEQ.
