I just got my CS-L and am blown away by the waveforms and textures I can get out of it.

Hands down the best complex osc I’ve ever had. So easy to get great sounds out of it and mind boggling possibilities.

I just got an Optomix again after not having one for years and they're so fun together.

Awesome! Would love to see Jason Lim make an LPG... his take on the Buchla 292 Quad Dynamics Manager.

I use a Make Noise LxD with my Cs-L all the time - often like a VCA, the vactrol softens the harshest edges, and then into the I-o47.
Here is a track to hear this patch in a mix.
Bassline is the Cs-L (upper pulse multiplied with lower sine, cross-FM) -> 6dB channel of the LXd -> into the I-o47 crossfading LPF and HPF;
with Frap Tools Falistri for AR envelopes to the LXD and to the cutoff of the filter.

Guys can you do a test for me ? On my CS-L I barely get any sound out of the Wavefolded Sine out until the wavefold amount is past the W or A in the 'Wavefold' text above the slider. Is this normal?

@zerodivide, yes it is a normal behaviour, more you go high in the frequencies less this effect is important
it is one of the character of the Cs-L, very interesting with modulation in fact

It would make me so happy if this was a thing. I've been really hungry for a quad LPG. I'd prefer it to all the quad VCA options or two dual LPGs.

For that track - I was using a borrowed Rene2 for the Cs-L I-o47 bassline.
Since then - my Frap Tools USTA arrived (which will be permanently etched in my mind as the last public thing I did before going into self-isolation).
USTA is mind-blowing.

Using this with an envelope can give you some very twisted low-pass gate/VCA-type effects.

it just seems like it's missing some low-end /bass when I compare to the Verbos CO. At a low frequency, I'm seeing some big gaps in the frequency spectrum at the bottom range. its a bit odd

Hey people, hope you're all well.

Although I'm tired right now, off to bed once I scribe this observation, this CS-L exhibited unusual behaviour tonight.

The primary oscillator was locked in LFO mode and refused to switch. I powered down and powered up but it remained orange light on stuck in LFO mode!. After a second re boot the module behaved as normal and came alive in normal audio mode, and yet, everything seemed slightly out of tune, even after tuning on the mordax.

Has anybody had a similar experience?

Tomorrow is another day and perhaps it will just be a bad dream but for sure it might keep me awake for a while even after my weary head hits the pillow.

Stay safe, keep well and all the best for the weekend

In this piece, Cš-L is mixing it up with Mysteron and Rings. Session notes are at the track's webpage:

I have a couple of questions:

1) will it retain all settings between power cycles, that is sound and behave exactly the same as when powered off?

2) is there a way to make sure it's in tune without a tuner (like an indent on the tuning knob(s) or by calibrating it so that 0V equals C with tuning knobs all the way ccw)?

3) how well does it track, say over 4-6 octaves?

Yes. All of the modulation settings are persistent during power cycles.

The top VCO registers C3 when using a 0-10V scale if you crank the coarse full CCW, and the fine will get it to C3 at around 9:00. The lower VCO is somewhere around 11:00 for C3 with a unipolar voltage scale.
For a -5/+5V bipolar input scale, the upper coarse knob is at 10:30 and the lower coarse is at 12:00.
This is fully analog - there is no tuner function or stepped knobs.

Good idea - I haven't actually tested that....
I just tuned my lower VCO to C1, and at C7 it's flat by 31.3Hz on the Mordax DATA. at C5 (4 octaves) it's flat by 6.7Hz. The upper VCO was only off by 3Hz at 6 octaves.
One thing to note - I just powered it on, I'll try again in 30 minutes once the VCOs have warmed up.
If it's the same result, I'm going to ask Jason Lim how to calibrate that lower VCO.

After an hour -
Here is the results on both VCOs of my Cs-L:
VCO C1/32.70Hz C3/130.81Hz C5/523.25Hz C7/2217.46Hz
Cs-L Upper 0% +1.3Hz +7.75Hz +10.2Hz
Cs-L Lower 0% -0.5Hz -6.45Hz -27.5Hz

By comparison - my Mutable Plaits - which is a digital affair, shows +17.2Hz at C7. So I'm not too troubled by the Cs-L.
On another note - stability... Plaits is showing a wavering/fluctuation of +/-.5Hz at C7. My lower Cs-L VCO is the same. So If this analog VCO can hold steady like a digital oscillator when it's cycling at over 2kHz - I'd say it PRETTY DAMN STABLE.

Thanks for chiming in, it's still on my list for sure after these very encouraging replies!

Thanks!

Here is some Instruo joy for you.
The three synth voices in this track are from a Cs-L and a Ts-L.
I think it's a good demonstration of how warm and organic these VCOs are.

From my track description:
The three synth voices are sequenced with Frap Tools USTA - leaning heavily on probability.
The first two voices are the two oscillators in the Instruo Cs-L, FM modulated with each other, and with each wavefolder modulated with a unique long, looping envelope from Xaos ZADAR. The output of each oscillator is gated with a Make Noise LXd channel pinged directly from USTA.
The last voice is an USTA sequence with a 12 - 1/4 note pattern, with an Instruo Ts-L running through a Frap tool Falistri envelope and 4Q multiplier as a VCA.
Spring reverb is the new Arturia Spring 636.
Beats on Ableton Live/Push 2.

Loads of Cš-L on this track, the first melody that returns later and the FM mayhem:



Also loads of Cš-L in this live set we did a week ago:

Anyone else had to recalibrate the pitch tracking on theirs? I never was able to get more than maybe 2 octaves of accurate pitch from it, decided last week (after a cocktail's worth of courage) to scrape off the glue that held the two pitch trimmers in place and try to calibrate it myself. Sure enough, there was a huge improvement and I'm now getting 5+ octaves of accurate tracking. Strange decision to glue the trimmers down...
It's done!
...probably! Ahhh, who am I kidding...

Had this module for over a year now. Really powerful VCO and sounds great. I have only one complaint. The LEDs on the faders are like frickin high beams! 😅 My studio is kind of dark and I can barely see with those shinning in my face. Anyone else feel this way? Other then that I love it!

I cut out some little strips of white electric tape to cover them up with. Just needs to be a bit narrower in width than the fader and long enough to cover over/under and so far they look pretty good, not too different from normal only a far-softer glow, and so far stick on pretty well. I did a couple weeks in have to replace one of the strips of tape that lost its hold, but it's not like it's expensive or hard to do, and otherwise after that they've been stuck on just-fine under use for months.

That video was the final straw that led to me buying a Cs-L. I've always liked using multiple outputs of an oscillator for different purposes and that takes it further than I've ever done.
