2HP MIDI-Expander
TRS-A MIDI in just 2 HP, for the case that ran out of room a while ago.
A small alternative to the Midi-IO Expander, with the same MIDI functionality minus the gamepad port. TRS-A jacks carry the signal rather than 5-pin DIN, with adapter cables included so it still connects to standard MIDI gear.
The third jack can be set as a second MIDI output or as a thru port, whichever a given rig needs more.
- MIDI in and out over TRS-A.
- Third jack: second output or thru, configurable.
- Same MIDI functionality as the Midi-IO Expander, without the gamepad port.
- 3 TRS-A to 5-pin DIN adapter cables included.
Not a standalone product — it works only with the NerdSEQ.
A TRS-A to TRS-B adapter is available separately in the shop.
