We are selling this vintage rack mount synth sound module. As you can see from the pics we know it powers up but we have no way of testing the functions. Being sold as is, if you have gear to try it out then bring it in and test it.
Here is a write up about it that I found on the web.
And here's one of the classic early ROMplers, the Roland U-220. The U-220 is the successor to the original Roland U-110, and it's the rack version of the U-20 synthesizer. Both instruments came out right after the world-famous Korg M1 had raised the bar quite a bit for sample-based synthesizers, and, like the E-mu Proteus/1 (that came out at around the same time), were meant to provide the users with a solid base of "bread and butter" sounds for pop, rock and dance music.
The U-series uses a type of synthesis called RS-PCM - which stands for ReSynthesized Pulse Code Modulation, and it's Roland's 2nd generation sampling technique. It is based on high-quality samples.
Besides instrument waveforms/tones, the U-220 also features drum samples. They are fairly punchy and typically with an 80s feel. You can certainly use these percussion tones to form patches - indeed, some of the more creative factory patches use drum sounds as starting points.
This is definitely a plug 'n' play, performance synth: this module responds beautifully to velocity messages, and also the aftertouch is incredibly responsive and guarantees "felt" performances. It's also 6+1 (for rhythm) polytimbric, so you can use it to compose full songs.
The U-series can also be expanded thanks to two slots for the SN-U110-series of PCM cards, which really open up all kinds of possibilities for this machine.
