! Why "Feet"? When developing synthesizers, many manufacturers indicated octaves the same way
they were indicated on electric organs, which in turn got their settings from pipe organs: by the length
of the pipes. Doubling the length would drop the pitch by one octave: 2', 4', 8', 16', etc. Many companies
used the numbers, but few actually called the control "Feet".
On the CS-80V, the octave (FEET I/II) and detune (DETUNE) are found to the left of the Tone Selector
buttons.
The waveform, which determines the harmonic richness of the audio signal. On
•
the CS-80V, 4 waveforms are available:
The sawtooth presents the richest audio signal of the 4 waveforms (it contains all
•
of the harmonics at decreasing volume levels in higher frequencies). Its sound is
ideal for brass sounds, percussive bass sounds, or rich accompaniments.
The square possesses a hollower sound than the sawtooth (it only contains odd
•
harmonics). Nonetheless, its rich sound (notably at lower frequencies) can be
used for bass sounds that will come out well in the mix (the square oscillator is
often set an octave below that of the sawtooth), 'woody' sounds (like a clarinet, if
the square signal is filtered), etc.
