"It’s basically one of the takes on Boss DR-55, authentically made in Japan. as far as I’m aware - these were sold as diy kits back in 80s, but functionally are identical to Boss DR-55, sound is also the same/almost the same.

please, NOTE, it’s been modified to be powered from … eurorack offset voltage.

power now is on minijack socket. you just take an offset from eurorack system, and plug it in to power the drum machine, directly, using eurorack patch cable. it will take any voltage from approx. 5v up to 12v.

it also has analogue clock output, and cymbal trigger output, so will sync with everything perfectly.

currently it won’t accept any other power sources, but it’s a very mod friendly machine! as mentioned above, they were sold as diy kits at some point, so they beg you for modifications. I believe it even can be modified to fit into eurorack housing, and it shouldn’t be hard."

Programming the Kay DRM-1 Memory Rhythm Machine

Published on Nov 14, 2014 zibbybone

"Here's a rare box I forgot I picked up a few years ago. It is very similar to the Roland / Boss DR-55 in design both style and sound. The DRM-1 features fully programmable bass drum, snare drum, closed hi hat and cymbal. Instead of a cymbal, the DR-55 has a programmable rim shot and the closed hat can either be turned off or play 8th or 16th notes. Sorry, I goofed up the bass drum rhythm (what I want to trigger on 1st step actually triggers on the 16th step), I was a bit rushed filming this video and didn't want to redo. Sometimes you get happy accidents programming this way."
