A lot of old school interfaces, no midi! The Oberheim DMX has some very rare 12-pin Molex connectors used for controlling TRIGGER and TUNE. Unfortunately the trigger in can only trigger the sounds which buttons are on the bottom row on the front. For example, only the CLAPS can be controlled, not the SHAKER 1 and SHAKER 2 because they all belong to PERC 2 and CLAPS is the one on the bottom row. CV IN controls the pitch with voltage between 0-5 V.
