Playing Around: Prophet 6 Arpeggiator Synced to Eurorack PEXP-2 

At the time I was using Pamela's New Workout with the PEXP-1 expander, sending MIDI clock from the eurorack to the Prophet. Now days I'm using the Hex Inverter Mutant Brains, and going the other way around, sending MIDI from the Prophet to the eurorack. If you want to pass the audio signal in and process it with your rack, you can use something like the Jorganaloge Receive 2 or just get a 1/4 to 1/8 adapter and run that into a 2 channel eurorack amplifier.
