Roland TR-505 trigger output modification


Published on Aug 11, 2013 Harry Axten·5 videos

"I installed two trigger outputs on my TR-505 which follow the high/low cowbell voice and the rimshot/clap voice. Internally they are wired to two pins on the surface-mount gate array on the underside of the mainboard. You can get the pinout for the IC in the TR-505 service manual (page 6)."
