I checked the waveforms coming out of my Vox SuperContinental, and there
are a fairly wide variety of shapes generated for the various individual
notes. Some low notes look like a cross between a saw and a square wave
(basically a square wave where the trailing edge droops down dramatically
toward zero), but with rounded corners. Some notes look basically like a
square wave, sometimes with rounded corners, and sometimes not so rounded.
Some notes look like a sine wave. The mixtures are complex and defy easy
description. There's a fairly wide variety. 

If someone tries to use a saw wave from a synth to mimic the Vox, they will
be missing the mark. There's too much variety here. To simply substitute a
saw wave (or any other single waveform) for everything and expect it to
sound like a Vox.


take care,
