About this listing
Yamaha's programmable "M" series monosynth from 1979: two VCOs, a switchable high/band/low-pass resonant filter, a sine-wave third oscillator in the VCA section, and 8 patch memories — rare on an analog mono of this era. Big, warm Yamaha CS-series tone. Made in Japan. The monophonic precursor to the CS-80.CONDITION- Fully functional. Every section tested: both VCOs, all three filter modes, both envelopes, LFO, noise, pitch and mod wheels.- All 37 keys trigger cleanly. All sliders, knobs and switches work with no dead spots or dropouts.- All 8 memory locations store and recall correctly, and hold after power-off.- Powers up and runs stable on 120V.- Cosmetically good for its age: light wear on the wood end cheeks, all slider caps present and original.
