Jon Johnson 208 Report post Posted June 12, 2017 The Susuzki RPM-40 multi PCM Ryhthm/Percussion Module was released in 1985 and also sold under other brands Siel and Keytek as the MDP-40. The unit is a preset drum machine but patterns can be chained together to create songs. All drum sound can be trigger by MIDI from an external sequencer or other MIDI instrument. The unit runs on 6 AA batteries or a 12v power adapter. Despite it's limits the RPM-40 is highly regarded for differing genres like Hip-Hop.
