The Pianoman 1,531 Posted January 13, 2017 Report Share Posted January 13, 2017 Doesn't seem to be a suitable category for this so I put ist ghere. I have just acquired a Roland Rhythm 77 or also known as a TR-77 drum machine. It dates from the 1970's and is intended to sit on top of an organ. I am unable to test it as I have neither organ or amplifier. Does anyone here know anything about them? Quote Link to post Share on other sites
