Roland MC-202

via this auction

"This is an analog synthesizer/sequencer. It sounds very much like the TB-303 and SH-101 bass synths. It has a very evolved form of TB-303 like programming (more like the MC-4) and SH-101 like controls of the VCO, VCF, VCA, LFO, Envelope and Mixer sections. The LCD display is a great feature too.

The MC-202 was sort of a next-generation TB-303. So the idea was to program sequence/patterns into it internally which would give you those 303 basslines that we've come to love. You can control it externally by hooking up a MID-CV/Gate converter. Then you basically have yourself an SH-101!

The sequencer is actually a 2-channel CV/gate sequencer, with both channels being capable of driving a separate external synth. It's a very useful unit, also, for its DINsync capabilities; it can receive on one port, and send over two, and also can 'split' DINsync to branch a sync signal out to multiple devices.

This machine is best for those who want to get 303-like patterns (it has accent just like the 303) and basslines with an SH-101 sound. If you can handle programming the notes into its sequencer you can have a lot of fun.

The MC202 is a sequencer and simple monophonic synth with 32 buttons arranged like a small keyboard (F-C).

The monosynth is similar to the SH-101. The VCO is based around the ever-so-popular Curtis 3340 chip and features a slider switch for octave (2', 4', 8', 16'), a slider for pulse width, and one for modulation (LFO) amount. The VCO outputs a square/pulse wave, a sawtooth wave, and a sub-oscillator which are mixed together in the "Source Mixer" section. The sub-oscillator is switchable between a square wave 1 octave down, a square wave 2 octaves down, and a pulse wave 3 octaves down. There are knobs which control fine tune and portamento. The VCF section has a slider for cutoff frequency and resonance. There is a slider for each of its control sources: envelope, LFO, and keyboard. The VCA can be controlled by a simple gate or the Envelope. The envelope is an ADSR with a slider for each stage.

The sequencer is quite powerful for its time. The MC-202 features a large (for the time) LCD display, upon which all the sequencing editing is displayed. The two available sequences can be played simultaneously using the CV/gate outputs to control another sequencer. The sequences can have a combined total of 2729 events. Sequences can be entered in real time via the pushbutton keyboard or via another keyboard using the CV/gate inputs. This feature has a negative side, though. Since all incoming CV/gate signals are routed through the microprocessor, there is a bit of a lag when the MC-202 is played by a another keyboard or a MIDI-to-CV device. The Sequences can also be programmed using step-time, setting a separate pitch and duration for each note. Also programmable in a sequence is accent and portamento. Accent works the same as in the TB-303, with an accent amount knob that can be adjusted in real time as the sequence is playing. The speed of the sequence is also controlled by a knob.

The back panel has a sync input and two sync outputs, a tape interface for saving and loading sequences, CV/gate inputs and two CV/gate outputs (one for each sequence), a headphone jack, and a main output jack.

The MC-202 came out at a time when the synthesizer market was just starting to impliment MIDI. After MIDI became an accepted standard, sequencers such as the MC-202, using the old-style CV/gate interface, quickly lost popularity and died away."
