CS15D is an extensive multi-sample collection reproducing the sound of the vintage Yamaha CS-15D, a great sounding monophonic analog synthesizer released in 1979.

The CS-15D is a monophonic analog synth with loads of character, one of the most solid and warm single-VCO machine ever. The synth features 29 preset voices divided in two mixable channels, plus a manual section featuring a variable pulse-saw oscillator, a PW modulator, a noise generator and a 12db filter with a dedicated ADSR envelope. Despite the use of realistic instrument names (Tuba, Oboe, Horn..) the 29 presets offer a variety of synthetic sounds ranging from fat basses to solid percussive organs and warm brasses.
