With 741s are you using a dual or single power to the chips?
Thanks

Hard to find those features on other sequencers (cheaply). The circuit uses two 741 op amps; one to scale up by a factor of about 5x, and the other to DC offset down a few octaves. If interested, yell.

Here for the gear
My original mistake (which paused me for a few months), was using a single power supply. I finally read "...most op amps like a (dual?) power supply...".
So I am using a +/- 9V power supply, even though all the CVs I'm using are (theoretically) positive. I guess, even if I use a 'Non-Inverting Amplifier' circuit, internally the signal must need negative voltages.

Does that make sense?

Aside from a back-to-back pair of 9V batteries, my power supply is a pair of back-to-back DC wall warts (not too close to 9V). I use 3 conductor PWM cables (black/red/white(yellow)) for convenient power cables.

I think I have used a single PS with a 741, but probably had a voltage divider for the 'ground'. (Not sure if that's legal.)

Just a question: Does anyone know, what exactly does the firmware update to version 0108 change (so far the latest one)?
Thank you for answering.
Enjoy your day!

I bought the midi in parts to mod, but the traces are micro small so I shelved the idea. The traces on the Monotribe are generous, by comparison.

Too low item to sell, so maybe some time in the future I will find a use for it!

Buying synths can sometimes be a hit-miss proposal.
I have seen many good YT uses for this box, but for the moment, it fell out of favour with me.
quoting you here for continuity - don't quite feel up to reading entire thread, or scouring YT right now. as you read, i'm not impressed with it at this point. even wondering if it is working properly > n00b - i got it 2nd hand (vgc, looks great, in box 'as new', even has orig. batteries)

i should be scouring the manual and example patches. (print too small.. have to download pdfs)

It does look nice and have left on shelf next to Waldorf 2 Pole and Vermona Retroverb. But unlike the latter items, the Volca Modular sits unplugged.

So as an art installation, the Korg Volca Modular is nice to have "hanging around"!
