miniMO 8-bit synth becomes midiMO mini sequencer
miniMO is a tiny box containing a very affordable 8-bit modular synth built around the ATtiny85 processor. Developer Jose Gonzalez has just released a software update and accessory kit to turn it into probably the world’s smallest MIDI sequencer – the midiMO.

The original miniMO was built as a completely open source project. So open source in fact that you can download the case designs and 3D print it yourself. And then pick up the components at a local electronics store and load the open source software. If you prefer the easy option then a kit with a pre-programmed processor will set you back just over 12 whole Euros.

The MIDI Sequencer software release reprograms the processor to act as a MIDI step sequencer. Apparently it’s easy to add steps and do some real-time transposition and tempo control. You can configure scales, mess around with intervals and octaves, take control of playback direction and note length. It even generates a random sequence on startup, or I guess you can keep power cycling it until it comes up with something you like.
Along with the software you’ll need the MIDI Out Accessory Set which includes a MIDI socket that wires into the headers on the miniMO. At nearly €15 the accessory set cost more than the miniMO kit but without it not a lot is going to happen.

You could pick up a pack of 3 miniMO’s and really start having some fun for around €60. Sounds like a great holiday project to me.
