I don’t see how using a comparator would sacrifice sound quality. PWM is achieved on most oscillator by adding a comparator circuit onto the oscillator anyway. Sound quality is never an issue on the Serge in any event. As far as the NTO and PCO being the only oscillators with excellent tracking, how many do you need? I have a hard time believing that the NTO or PCO are somehow not up to your needs.James R. CoplinFrom: SergeModular@yahoogroups.com [mailto:SergeModular@yahoogroups.com] On Behalf Of jalmari3

Subject: [SergeModular] Re: Considering SergeThank you for your input. I got some mail too. Here are more
questions:
- I couldn't figure out, if a DC coupled VCA with exponential
response is available by Serge? I would need one despite the fact
that Serge envelopes have selectable curves. (Modcan A series VCA:s
are linear. Their B series 13B has lin/expo switches. So does my
Cwejman VCA-2P, excpet that they are labeled "lin/log".)
- Are the blue jacks DC coupled and black jacks AC coupled?
- Regarding PWM, I realize that there are many ways to get a
rectangle waveform from a Serge system. However, one might suspect,
that using comparators and other auxiliary "tricks" might compromise
sound quality. Could it be argued, that for "classic" PWM sound with
good tracking I should rather go for a Modcan A oscillator? It
outputs only 5V peak to peak though. Would that be a drawback?
- Are NTO and PCO the only Serge oscillators with excellent tracking?
It is good to hear, that another banana system might come out. I wish
someone would make Serge-like 4U individual modules: As I am used to
Eurorack, 6U Modcan and Cynthia modules seem sexy but too big. Also,
I simply like to change and reconfigure my modules. That is why
the "Serge philosophy" of full or half panels doesn't seem appealing
to me.

in addition to the NTO/PCO oscillators, other modules offer "oscillating" capabilities, like the filters and Quadrature Oscillator, that showcase the multi-functionality of many of the Serge modules.
The philosophy of design has been to provide modules that, depending on how they are set, can provide different functions depending on the role assigned - examples of these are the SSG/DSG/DTG.
So when looking at an Animal panel, for example, it would be easy to think that there are only two oscillators, when in practice there could be as many as 4-5 oscillating sources.
There might be sound quality issues present in pre-STS panels due to uneven production quality, but as James stated so well, the last thing I would be concerned with in a STS Serge is sound quality degradation.
Cheers -- Bill
