TRON DigiDrum Sampler
Not much shows up on google when searching for the TRON DigiDrum but according to some website (which sells one unit) it seems to be a:
"...Drumcomputer Cartridge with software (tape) for sound-editing and rhythm composing. 16-Step Trigger-Out for synchronising with external equipment..."
Well.. according to the pictures I would say it's a sampler cartridge built in 1986 by DCS/TRON that included some drum machine software to trigger the samples. Probably the basic sample editing functions too. But, I don't quite get the 16-Step trigger out thing... anyone knows more about this cartridge ?
