Note this does not have any sequencing capabilities. It is a drum synth aka drum brain.
"This is a fully working very rare Pearl FM-8 Fightman Analog Drum
This Drum Synth is very hard to come by, trust me.
This unit does not have Midi.
I will include 2 homemade adapters that have 3.5mm inputs so this can be triggered with a trigger sequencer like a Beststep pro, or Modular Synth."
You can find a video of one posted here.
