1.1      What this Expansion Pack is All About

The YAMAHA CS-80 is undoubtedly one of the most remarkable electronic musical instruments, which the manual of the instrument introduces with the following words:

"The CS-80 is a unique step forward in synthesizer technology, an advanced and very playable instrument.”

As early as the mid-1970s YAMAHA built

  • a weighted, i.e. piano-like, velocity-sensitive five-octave keyboard with sixty-one (61) keys and polyphonic aftertouch,
  • a huge ribbon above the keyboard used for pitch bend effects, and
  • two times eight oscillators, eight of which are allocated to each of the two freely programmable, identically realized channels of the CS-80:

The YAMAHA CS-80 is an eight-voice polyphonic synthesizer. In contrast to numerous competitor products of that time, the YAMAHA CS-80 is not based on frequency divider circuits typical for transistor organs, it is a genuine synth.

Each oscillator can simultaneously generate the "waveforms"

  • rectangle or pulse width ("PW") or pulse width modulation ("PWM") [switchable on or off],
  • sawtooth [switchable on or off],
  • (white) noise ("NOISE") [continuously adjustable] and
  • sine [continuously adjustable]

in any conceivable combination.

The YAMAHA CS-80 has eleven (11) PRESETS per channel, namely


Channel I has the following PRESETS (from left to right):

  1. STRING 1,
  2. STRING 3,
  3. BRASS 1,
  4. FLUTE,
  8. ORGAN 1,
  9. GUITAR 1,
  10. FUNKY 1 and
  11. FUNKY 3.

Channel II has the following PRESETS (from left to right):

  1. STRING 2,
  2. STRING 4,
  3. BRASS 2,
  4. BRASS 3,
  5. BASS,
  8. ORGAN 2,
  9. GUITAR 2,
  10. FUNKY 2 and
  11. FUNKY 4.

The velocity sensitivity ("INITIAL") can be set independently for each channel and individually for filters ("BRILLIANCE") and volume ("LEVEL"). The same applies to the aftertouch ("AFTER"):


In addition, the aftertouch intensity for the LFO ("SUB OSC") and the velocity sensitivity can be adjusted as common parameters, affecting the PRESETS of the instrument, also.


Even keyboard tracking is adjustable independently for filters and volume.


The YAMAHA CS-80 was at least one decade ahead of its time.

The illustrated are just a few of the remarkable features of this amazing musical instrument. It is no wonder that many world-famous artists used and still use this wonderful instrument for their recordings and live performances.

It is therefore important to KApro to provide a selection of the best-known sounds which the YAMAHA CS-80 contributed to many world hits for the YAMAHA GENOS.
