JH's VCO, wavetable source, variable ramp

[mbartkow at ET.PUT.Poznan.PL]

BK and HB:

I agree, many sampled waveforms are boring, especially when heared
as a static wave. But the same applies to sine, saw and all the classic
synthesizer waves. The sonic beauty is hidden in the possibilities of
dynamic shaping (and especially filtering) of them.

I cannot agree with the general statement that various waveforms sound 
alike. Yes, they may sound similar if listened to in their dry form.
But again, selective filtering reveals the differences in their harmonic 
pattern.

For my wavetable generator I do not intend to put any sampled instrumental
waveforms, though. I rather think about artificially generated spectrally rich
ones. A special program running on a microcontroller will be responsible to 
generating of waveforms according to the settings of few knobs.

MC:

I can hear a vast difference between variable ramp and PWM waveform, especially
when reasonably filtered. Moreover, a PWM wave may be waveshaped out of var.ramp,
but the opposite is not so easy. My point is not to consider the var.ramp as the 
most interesting timbrally one, but as a very universal tool to obtain many other
waveforms by the means of waveshaping.

best regards,

mb
