I think people generally do a disservice to complex oscillators in reviews because in everything I’ve seen from the DPO to the Verbos to this, the reviewers tend to spend way too much time in the extreme settings zone with crazy FM and everything going. It’s like those bluez wankers playing distorted solos during the whole guitar review , it’s hard to get an idea of what the thing actually sounds like. I can say with spending some extended time with the module that you can get some really mellow tones with it as well. There’s a few great things about this VCO that stand above the rest for me:
-Having two cores, and triangle and a saw, is really a brilliant idea. There are some subtle harmonics present in a sine wave created from the saw core that seem to be filtered out of the triangle core which are very nice to have when you want the sine wave to pop through the mix. Also I’ve noticed that the wavefolder is a little gentler on the triangle section. Which brings up the next point…
-Two wavefolders, this is so nice. I don’t think there’s another CO I’ve seen with two of these.
-The tuning is really stable, best I’ve encounter for an analog VCO thus far.
-The fm is really usable for me in a harmonic way to at least half way up the linear dial. Much more than other VCO’s I have used in which those tend to lose the fundamental of the note much more quickly.
-Built in ring mod
-Having the ability to let both cores track off of one v/o input with the flick of a button is so nice. This means you can keep an fm patch in tune while playing up the scale. It keeps the relationship of the tuning together, so if you tune one VCO a fifth up from the other it will maintain that relationship as you play. It’s really great to have that built in.
I’ve never owned a Buchla but from listening to a lot of Buchla based stuff lately, the CS-L sounds really close to the 200, at least from recordings.
I’ve previously owned a Pittsburgh Primary Osc, a Sputnik Oscillator and an STO, and I think the CS-L falls somewhere in the middle of all those. The Pittsburgh was a pretty gnarly in the high end while the Sputnik was pretty cleanish and warm and the STO had a nice upper mid range presence. The CS-L does have a high end presence, but there’s a clarity that does not make it grating to the ears like the Pittsburgh. I find myself reaching for the more harmonically complex waves more than I would normally because I only own one filter and usually I don’t like something like a raw square wave because it almost hurts my ears, with the CS-L it doesn’t seem to do that.
I highly recommend this, as you can tell I’m pretty stoked so far. Maybe I’ll make a quick demo of the non extreme settings if I have time.
