Arduino based Midi Trigger box for analog synths

I usually control my volca and the Mother32 via midi and create sequences using Bitwig studio or Sonic Pi but I wanted to use the build in sequencers to create a more hands-on feeling and simplify loop creation while jamming but haven't found a satisfying what to synchronize the sequencers to each other and to my computer

I considered buying a bastl klick - but I would need several of them to control different synths at different clock-rates and I would have to sacrifice several audio outs to control them.

So I build a midi-trigger system using an arduino that allows me to send trigger signals to 4 devices using midi note-on signals. Now I can run the sequencers of my devices at different clock rates allowing me to use longer or shorter sequences or create different rhythms by sending trigger signals with different note lengths to the DFAM. Sort of like a clock-divider on steroids combined with a sequenceable trigger pulse.
