Released 1981, the SH-101 monosynth looks like a 1-voice Juno 6. But unlike most of Roland's previous instruments, which were chunky affairs designed for use on tabletops and stands, was constructed from high-density plastic, with the result that it was extremely light. Some players derided this, equating its weight to its sound, but this was foolish.
The SH-101 sounds excellent, and there was a good reason for its construction. It was designed for posing. With the optional MGS1 modulation grip - a stubby handle that provided LFO and pitch-bend controls - became the de facto standard sling-on synth for the electro-pop crowd, and remains one of Roland's enduring successes. The 1981's SH-101was an instant classic, and is still popular today.
There is no patch memory storage and although it has no MIDI there are upgrades available for it from many analog service companies that will allow you to incorporate it into any MIDI studio environment. It can also be controlled by MIDI using a CV/MIDI converter. It's great for bass sounds or bubbly analog effects. They come in three different flavors - grey, blue or red and there was a ultra-rare white version too.
