"I recently picked up a very nice Ace Tone Rhythm Ace FR-1(This company became Roland). This is an early transistor drum machine that has a variety of presets you can select. You may also press multiple choices and use some mute buttons to vary things. I noticed in the back there is a port for some type of plug. I thought it might be individual triggers for the independent drum sounds which would let you program your own beats.
I chopped off a few old wires and connected them to some of the banana jacks on the BugBrand to see what would happen. I only cut 3 wires so you only can hear 3 sounds I hook up. Kick, Tom, Hat. Clock is coming from the Acidlab Bassline V2."
