I'm almost done going through the manual, and I have to say my time with this module already is worth the price of Eurorack admission

Got mine yesterday! :goo:

Aliens have invaded my studio. My neighbors are totally screwed.

This oscillator is a mad scientist’s workshop in 26hp. :zombie:

It really is more than the sum of its parts.

Anyone have black Rogan knobs on theirs??

Hi, could I trouble one of you lucky CS-L owners to record a few slow and fast sweeps of each oscillator’s individual outs (mainly triangle, square and saw) please, and stick it here or on soundcloud for download? As I’m really curious how these sound.

here you go..

starting with the lower osc square wave, sub 1 and sub 2. followed by primary osc triangle, saw then sine.

a slow sweep up and down. the primary frq is set full anticlockwise whereas the 2nd is pitched up a little to bring the sub waves within a reasonable context.

Thanks, joncharliefeathers! Appreciated!
Sounds fantastic. Very smooth and deep actually.

Entirely thanks to this forum, I ordered one of these today in place of the DPO I had been hankering after. Realised I was excited about the prospect of a cs-l in a way that I just wasn’t about the DPO. Excited!

Yes, that's brilliant! Definitely interested. Just need to "move" a couple of modules first.

I'm swapping my CS-L for a DPO I think :)

Do the potentiometers on all the instruo modules seem to have a lot of backlash to you all? They feel great otherwise, but it can be a little difficult to really dial things in with all that wiggle room. I have not heard many people mention this, but I did see one video on youtube talking about it:

https://www.youtube.com/watch?v=YZAg-jT0C6w&t=4s

Is it the same for everyone (and also across modules)?

I have a Cs-l and I read about some “play” in the large Osc tune knobs. I just got mine a few weeks ago so I tried a couple of slight pitch tunes and fm’d them in various ways (so many ways!) I didn’t notice any issues at all. As for the other knobs, I notice on some settings the the other knobs might have a more defined sweet spot. But I chock that up to frequency manipulation, not being equal in all amounts to all degrees, rather than some kind of defect. In fact I’m rather impressed with the rage on the vca’s and fm knobs and being able to use them (mentioned in the manual) at 1v/oct when maxed out. In fact thinking about it, I’m hard pressed to come up with any VCO modules in my kit that I could claim had such a massive useable range. But I must admit I prefer the low end of sounds that scare dogs and children. :woah:

I just tested the Cs-L the other day, after over a year of using it. It tracks perfectly over six octaves—perfectly. It sets a benchmark for analog osc performance.

I think you guys are misunderstanding me, I am not saying anything about usable range or tracking, I am just talking about the potentiometer backlash. For example, if I am turning the pitch knob clockwise to turn up the pitch and then I want to turn the pitch down and I start turning the knob counter-clockwise I have to rotate it a bit counter-clockwise before the pitch actually starts decreasing (and vice versa). The cs-l I have has a lot more backlash than any other modules I have used and was wondering if they are all like this or it is just my module.

No misunderstanding--I was posting an observation about a tracking test unrelated to your issue. Speaking to your issue, I haven't noticed anything unusual when tuning the Cs-L--it seems easy to tune. Maybe I'm not noticing the effect you mention, but if I can dial in a tuning without a problem--it's ok with me.

I would describe the effect as “play” (as in “the play of the steering wheel of a car”) rather than “backlash” (which is something different altogether). Mine exhibits the same behavior.

I don't consider it a defect, however, but rather a small blessing, as it prevents de-tuning by the slightest touch.

Thanks for letting me know I am not alone or crazy :tu:.

The technical term is backlash however, for example see:

No, you're not crazy (though I'm not sure I can say the same about myself).

Thanks for calling my attention to the technical use of the term "backlash". I wasn't aware of it.

As for other Instruō potentiometers having exceptional amounts of "backlash" I'll need to get back with you on that as there are quite a few on my system to examine. :razz:

Now that is a system I am jealous of! You already have a lion I see. I have an arbhar on preorder that I am super excited about, maybe next month fingers crossed :).

Arbhar is indeed something to be excited about. :party:

Of all the Instruō modules I have, I'd say that one’s the most spectacular. It can almost be too much at times.

Speaking of arbhar, I just tested its primary potentiometer, the scan knob. It has a similar amount of backlash as the oscillator frequency knobs of the Cš-L.

Again, I see this as a positive, as it helps prevent unwanted changes if you accidentally brush up against the potentiometer while reaching for something else. I don’t know if this was a design decision or not, but so far I’ve not found the backlash to be a problem on any of the Instruō modules, even when tuning oscillators.

Yes, I am excited about hooking the ochd up to it for sure (didn't notice one of these in your system :)).

Great to know about the knobs, thank you so much again for letting me know! I am loving my Cs-l. I got an STO as a second oscillator, but I am thinking maybe I should have gone with a Ts-l, then I would have a small oscillator I would also love to have in a portable case.

Best!

Been playing around with this thing A LOT for the last week. Probably my favorite sounding complex oscillator and I love all the variety of sounds you can get. My one pet peeve is the noise/bleed on the wavefolder outputs that you can hear when they are fully to the left (the top oscillator is worse in this regard). Just something you have to avoid, but it is annoying when you are wanting to "strike" the wavefolder or when you want to isolate an external signal for wavefolding. If it were not for this I think the module would be nearly perfect.

Not noticed this on mine though it does have a hefty signal. Only bleed I’ve notice is through my VCA.

Is it perhaps because of an internal routing? There are so many I could see having one on and forgetting about it.
