"Ultra rare electronic vintage drum synth trigger module Dynacord Percuter, made in Germany in 1985!
The Dynacord Percuter has 8 channels all with individual outputs/inputs and uses Dynacord cartridges with 8K eProms inside: if you have imagination you will work out how to exchange the eProms and customize your electronic drum sounds!
The only knob that doesn't work in the unit is the pan knob for the channel 1: the channel 1 works perfectly, only the “pan” (right/left) doesn't work in this channel (it probably just needs to be cleaned or the potentiometer needs to be replaced: we are not technicians). Everything else works perfectly!
Drum sounds can be pitched up and down with the pitch knob!
Totally analog unit, with really fat and super cool sounds!
It comes with the following 6 cartridges:
• Natural Rimshot
• Natural Snare 8”
• Natural Tom 13”
• Natural Tom 16”
• Natural Bass 22”
• No Name"
