The SH-101 is very cool, especially for techno, drum&bass and ACID! It's a monophonic bass synthesizer. Its sound lies somewhere between the TB-303 and a Juno bass sound. It has a lot of simple but cool features. You can control the VCF, pitch, LFO or all from the pitch bender. It has a white noise generator, arpeggiator with up, down and up/down patterns and a simple real-time sequencer. The LFO offers random, sine, square or noise waveforms. And normal or auto portamento effects give you that elastic bass sound. There are external clock inputs for the sequencer and arpeggiator, CV/GATE inputs and outputs and a CV hold pedal.
The keybed on my mk1, I find is better then the original SH-101 that my friend owns. It just has an annoying slight initial 'klack' when you 1st play a note. (although mine is an early MS'101', so maybe it was changed early on, like they did with the Odyssey LEDs). The keybed...
