This is a rare soviet analog drum synthesizer with two velocity sensitive trigger inputs, dedicated to control both sound generation circuits, typically used for bass and snare drums, but not limited to that type of sounds. Works fine with CV sequencers, such as Arturia BeatStep Pro. Contact microphones could be used as well. The module exhibits some wear and tear, especially at the bottom side of the panel (see last photo), but functions perfectly. DIN5 sockets on the back have been replaced with regular 1/4" jacks. Drum pads are not available. I would prefer to ship to EU, but feel free to contact me if you're located somewhere else or would like to know any further details. The item is sold as described.
