Ebay Description:
The Yamaha CS-15D is a 37 key, monophonic analog synthesizer, featuring dual signal paths (oscillator/filter/amp), an LFO (sine, square, S/H waveforms), 29 presets (ch1:15, ch2:14), and CV/gate IO. Each signal path features an oscillator (saw and pulse waveforms) with portamento, resonant low pass filter, and dedicated (ADSR) filter and amp EGs (channel 2 also has noise).
