Hi Matrix
It could sound crazy but I built it by using the internal tone generator of
Cool Edit....the only doubt I have is what compensation should I give to the
high harmonics in order to eliminate the filtering made by the EXP
circuit's lowpass filters , there either Crow or David or Juergen can help,
and I wish they will.

> One of the things I always believed that showed the magic of CS
synthesizers was the ringmodulator, the richest I ever heard . If anyone
thought that this magic was in the ringmodulator itself , well , the
multiplier circuit is nothing special really....what I discovered on the
other hand is that the waveform used as the modulator is very special : the
sine that was outputted by the iG00150 LFO was indeed a "wrong" sine : I
mean it is not pure, and when I say this I mean it has some harmonics that
contribute to enforce the fundamental and enrich the modulation therefore;
thanks to a sample that Georges Poropat provided me with I made a FFT
analysis of this wave and I found that there are 9 more significative
harmonics that influence the waveform, each set to different amplitudes and
mostly of the odd type; moreover there is a phase difference between each
harmonic that provides a noisy high end and gives another particular flavour
to the sound; the audio result is that , even with

> low frequencies the modulation sounds very rich, in fact the full speed
without modulation doesn't go beyond 220Hz and the full modulation with the
envelope goes no further than 2500Hz...what amazed me is that I was able to
synthesize this wave by layering these 9 sines at their respective
amplitudes not forgetting to to give a compensation in amplitudes related
with the "expression circuit" lowpass filters' influence ( 6dB/Oct at 1KHz,
but I'm speculating there ). The result of modulating waves with this
special sine is 99% faithful to the original...if anyone would like to hear
this experiments I can post them on the site.
