Ununseptium Warehouse Eurotron Delay - Eurorack Modified Korg Monotron Delay


Published on Nov 14, 2014 Unun Septium

"Korg Monotron Delay 'Eurofied' and sequenced by a Verbos Voltage Multistage, processing a Roland TR-626"


via Ununseptium Warehouse where you'll find additional pics & build notes.

"It's not a difficult mod, but not everything does exactly what you'd think it might. I added inputs for 'Pitch', 'Gate', Filter Cut Off and LFO rate plus an output for the Oscillator. I also converted the annoying stereo aux in and headphones out into regular mono so they connect easily to other modules or other mono outboard gear. The final thing was to change the power supply from battery to 5V Eurorack.

'Pitch' and 'Gate' have inverted commas for good reason. Although there's a solder pad on the pcb marked 'Pitch', it doesn't really allow the oscillator pitch to be controlled by 1V/Oct CV, as one might expect. There's probably some elaborate way of making this happen, but that's clearly beyond my ken. However, I did find it responded to the volts coming out of my home made Velleman LED sequencer. I can't really say I know what it's doing, but it does something and that's enough to warrant giving it its own jack socket. 'Gate', on the other hand, does more than it promises. Sending CV to this, from the MiniBrute keyboard or the Verbos Voltage MultiStage, gives a response from the oscillator pitch and its gate. It doesn't really track in any meaningful musical sense, but using a sequencer or arpeggiator means simple melodic patterns can be created."
