Vintage Acetone Roland 70's Monophonic Analog Synthesizer

via this auction

"To me it sounds a lot like an SH-1. Lots of bass, very cool pulse modulation capabilities... Pure monophonic analog goodness. A lot of simple usable options and features that make for basically just really a very fun and easy to program and play piece of hardware. Filters are sweet as (same as SH-1 I believe). All sliders, chips, oscillators, filters, pots, knobs and switches work 100% correctly as far as I can tell - definitely happy to make a sample video and/or have a test play on pickup though.

An interesting feature of this unit is the analog 1/4 TRS in. Basically you can pipe any mono audio source in, then use the great resonant analog filters on this machine to warm up/filter your signal. I used this feature a lot to warm up my digital synths, passing them via the Acetone filters.

There is also a TRS jack marked 'EXT. MODULATION'. I, nor anyone I could find online has been able to quite figure out how to utilize this yet though."
