SQ-3P - Eurorack MIDI step sequencer

The SQ-3P is a MIDI step sequencer inspired by the sequencers in the Roland JX-3P and SH-101. I use the Arduino platform for it.

This is the module version of the prototype

This is the prototype housed in a simple case

The final system will consist of the main module and one or two connector modules

left the in/out/thru module, right sequencer module. The simple in/out/thru module might be available also in a version with 3.5mm sockets


the maximum combination: in/thru module, three sequencer modules, triple out module. You can control up to three main modules from one input (=one keyboard); all sockets are available as DIN and as 3.5mm jack.

I also wrote a first draft of an owners manual.
