<div dir="auto">Dear list,<div dir="auto"><br></div><div dir="auto">Being an early Genesis fan I know the solo's of Tony Banks on the Arp Pro Soloist very well, but only recently discovered the rather unique architecture of this synth, and primarily it's capability to generate fixed width pulse waves (the width is not a fixed percentage of the wavelength, but really fixed in miliseconds).</div><div dir="auto"><br></div><div dir="auto">Then I started reading about the theory of Pulse forming synthesis, and how that was applied in the Variophon, for analog physical modelling of wind instruments. The main message as I understood is that a fixed pulse width waveform yields formants areas in its spectrum (independent of the waveform's perceived pitch).</div><div dir="auto"><br></div><div dir="auto">Then I had a look at my MI Braids oscillator and the impurities of the CSAW oscillator model, modelled after de CS80 waveform. And I wondered about the things:</div><div dir="auto">1. Could the oscillator reset time of analog oscillators impose a high frequency fomant area in the spectrum?</div><div dir="auto">2. Assuming that the shape of the CSAW is modelling oscillator reset time, shouldn't the artifact remain static in time, and independent of pitch? The Braids model artifact changes proportionally to wavelength... Is that also what a real CS80 would do?</div><div dir="auto"><br></div><div dir="auto">Rutger</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Op di 13 jul. 2021 07:11 schreef Roman <<a href="mailto:modular@go2.pl">modular@go2.pl</a>>:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr" style="margin-top:0;margin-bottom:0">Or MIDECO if it only was available at the moment.</p>

Then I would not care for MIDI->CV, because the stringmachines di
not use VCOs.<br>
<br>
All you need is a MIDI to (61-folded) switch interface.<br>
You may do it yourself with an arduino, <br>
or use something like <a href="http://www.doepfer.de/mtc.htm" target="_blank" rel="noreferrer">http://www.doepfer.de/mtc.htm</a><br>
