Open Source Multi-effects MIDI Pedal

US Custom modifier to buy or build yourself      22/08/25

Sometimes you need to move your MIDI, and without a DAW to convert the data - you might need a custom solution. Here's one from Romagnetics who built a MIDI modifying pedal which allows him to change the tempo, the MIDI channel, the velocity, and the notes from the on-board controls. All effects can be toggled independently and configured via the onboard screen and encoder.

Here's more... 

The Romagnetics Midynamite is a compact, battery-powered MIDI multi-effects pedal with three physical MIDI DIN 5-pin connectors and USB MIDI device support. It can function as a standalone pedal or as a USB MIDI interface for a computer.


You can buy the completed unit yourself for $249 here or dig out the goodies for yourself on his GitHub page. I'd be tempted to stick an Arpeggiator and MIDI echo on there myself!
