Subject: Re: [yamahacs80] Square wave

Thank you so much ! Correctly my friend Laurie wrote me that the audio result of the pure wave could be heavily affected by the actual settings of the filters' trimmers into each M-board.I'm aware of it and I will do my experience having the final results on a statistical shape.
I recently analysed the sine wave into the ring modulator and ended up with some correct datas ( or at least as less approximated as I could ).
Well, the sine wave I can hear into the modulation wave ( and in the PWM , SubOsc and within Chorus LFOs) isn't a plain sine: it consists of a "wrong" sine wave with a single harmonic tuned 2oct upper and with 4% of the total amplitude, I was able to reproduce it digitally with a common FFT generator : this implies the fact that , within ringmodulation there is something like a "hidden" sine which modulates the signal togheter with the fundamental at two octaves upper....that's why its sound is SO rich!!
Thx again for your help!
Max

I'll be happy to help out, but I won't be able to get to it until much later
tonight or possibly tomorrow. If someone else wants to step in before that,
then fine by me too. But I'm stuck at work here now and won't be near my CS
until later this evening.
