any way to CV control coco chaos & master frequency knob

Post by odditymedium » Wed Jan 23, 2019 10:48 am

dunno if its got another name.... but the master frequency of the quantussy and the chaos knob... can i cv control them?

the green imputs near these two knobs are to CV control sampling the inputs right?

The lack of these inputs is the reason I did not get a Coco thus far :)

:hmm:

I didn't buy a Tesla because it couldn't make fart noises.

seems odd

Wow, what a genius analogy.

No, just by hand

Thanks!

After reading I ment it less awkward.
Reading your comment didn't make sense to me. CV functionality could be nice but it's not the main selling point of the Coco hence my analogy.

To me, the main selling point with any Ciat-Lonbarde instrument is 'stepping into the unknown'. Therefore any question remains pertinent. :)

I've asked this before, but after getting to understand the internal architecture of the Quantussy more, I understand why these are knobs only.

If you add CV access points, you will add an instability to an already kind of fragile system. The FM inputs are better tools for trying to re-pitch an oscillator, and if you want to have a bit more fun, throw a variable resistor inline, and add a CV to that. To put CV points into the Chaos and Pitch controls would require the addition of VCA's at the output sections, which there is no room for on the circuit boards or in the body of the instrument itself. It's already quite full in there. Not only that, but as fun as you think it might be, the probability of getting usable sounds out drops significantly. Peter Blasser is a VERY intelligent fellow, albeit a bit ~eclectic~, and the lack of CV points is intentional. If the absence of them is holding you back from buying one, please put it out of your mind. The Cocoquantus is a masterpiece as is. I wasn't sure when I got mine, but a year later, I have no doubts.

It is, as is, the Transdimensional Portal Key. If you're ready to get lost, get a pack of these, plug them into the sockets, and bridge the connections with your fingers, or anything else you'd like. Your world will change.

A simple way to do it is to cut the traces that connect V+ to the input of the voltage dividers and replace that connection with a jack. The knobs would then work as attenuators for an external signal instead of working as offset controls. Add a toggle switch to select between the external input and stock operation.

There are more complicated ways to do it that preserve the stock operation, but you'd probably need a bigger box to fit them.
