[Q] RCO (Ramp Controlled Oscillator)

[Q] RCO (Ramp Controlled Oscillator)

2002-11-16 by Tentochi

I saw a reference to RCOs used in the Jomox SunSyn. 
Is this just marketing hype?  The more I read, the
more it seems like they are just wavetable playback
oscillators; although I could be very wrong.

Here is a little blurb I found.  There is less info on
their website.

Thanks!

>>> The SunSyn is fully analog, but it doesn't share
the typical sound-limitations of other analog
synthesizers because it has a feature called RCOs
(Ramp Controlled Oscillators). This is the first
synthesizer which allows you to play complex digital
waveforms with the timbre of the analog VCOs.
Additionally, it is possible to use the classic VCOs
by themselves. The RCO follows the VCO with all the
fine tunings and frequency alterations that the analog
VCO does. This results in a completely new expression
for waveforms that formerly was not possible in the
analog and pure digital worlds. The complex digital
waveforms start coming alive when driven by the analog
oscillators. Other than that, the RCO's follow all the
movements of the analog VCOs, such as modulation, OSC
sync and restart (phase starts new at retrigger).
Furthermore, it is possible to give the RCOs their own
relative pitch.

This sounds exactly like a VCO followed by a Miniwave.

Which I think many of use will agree is a really cool thing. :)
Thanks Paul S, Grant R, and John B. :)

Yes. The 'ramp controlled' part refers to the fact that on a 
wavetable whose position is controlled by an ADC front end, an input 
consisting of a positive sawtooth wave (or ramp) will play back the 
wavetable from beginning to end. 

That's cool, but having the combination modularized (ala MOTM-300 
into MiniWave) allows us to play back the wavetable in lots of other 
permutations just by using different input waveforms. That's cooler!

Ooh, wow, I never thought of that. Gotta start building my MiniWave, now
that the arrival of its Stooge panel is approaching (right?).
