Selling my Roland TR-77 drum machine from the 1970s, in very good condition. Here’s a list of the modifications done to this unit:

  • Added trigger mod by circuitbenders.co.uk
  • Added sync in
  • Comes bundled with a Eurorack breakout and DB15 cable
  • Replaced the old noisy PSU with a modern equivalent

Factory presets can still be played on top of triggered sounds


The breakout is assembled on a PCB, so if you don’t use Eurorack you could easily build your own box and mount the PCB inside it.

*Stand not included.
