"Made in England in the 1980s and rare to come across.
Has a trigger/input for each of the drums (bass, snare, hi tom, med tom, low tom)
Each can be controlled with sensitivity level & output level.
Each drum also has it's own output (if you want to pan individually into your DAW), or you can run mono or stereo out of master outputs.
This is the Midi Version of the SDS1000 module (hence the M in the title), that was designed with Midi In/Out - SO, with this brain you can also use your Simmons kit to trigger more modern sounds from DAW's, etc.
Includes rack mounts on sides (which are easily removable if desired)
Controls for each drum: Sensitivity / Filter / Pitch / Bend / Hit Samples / Body / Decay / Noise / Click
Save programs/patches. Trigger LEDs for each drum. Drums can be triggered by a sequencers, trigger pads, etc."
