Mulogix Slave 32 For Sale. Made by Music Logic Systems, Inc. This is the rack of the Digital Keyboards DK Synergy 2 synthesizer. Wendy Carlos is likely the most famous Synergy user.
This unit is now part of the massive vintage synth museum worthy studio collection at The Synth Sanctuary. Feel free to make an offer, but it's likely going to stay where it is. Or, if you have one to sell, please get in touch.
