Released: 1977

MSRP: Y225,750

Synopsis:

Basically a CS30, substituting the sequencer for more performance controls (portamento, sustain, filter pedals/sliders). Architecture Class: Conventional (subtractive).

Ebay Description:

The Yamaha CS-30L is a 44 key, monophonic analog synthesizer, featuring dual signal paths (oscillator/filter/amp), an LFO (external, saw:down|up, sine, square, S/H, waveforms), ring mod, 3 envelopes (IAADR, dual ADSR), external filter input, and CV/gate IO. Each signal path features an oscillator (saw and pulse waveforms) with FM and portamento, noise, and resonant low|high|band pass filter.
