Developer Jose Gonzalez, creator of the miniMO 8-bit synthesizer, let us know that he’s released an add-on kit that turns the miniMO synthesizer into the midiMO MIDI sequencer.

He calls it ‘the smallest and cheapest sequencer on the market today.’

miniMO is based on a MIDI sequencer app that you load to the midiMO module. It lets you use the module as a pattern sequencer.

In addition to the app, Gonzalez has introduced an accessory kit that turns the miniMO into a standalone, MIDI-out capable device:

• A female MIDI adapter to connect miniMO to any device with a MIDI Input
• A three-pronged jumper to power both miniMO and the MIDI adapter from the internal battery
• A custom 3D-printed enclosure with flexible outer cover
• Two laminated faceplates: one generic, one with custom markings for the sequencer (shown in the picture)
• A Davies-1900h clone knob with brass insert and set screw
