Keep the PCB powered on for 30 minutes or more before calibrating (close windows or vents during calibration).

Unfortunately I'm experiencing a pretty low volume on output in comparison with my other VCFs.
There is something I can mod in order to archive an higher volume on output and mor ... lilpaula87 Fri, 21 Oct 2022 10:59:19 -0700 https://electro-music.com/forum/viewtopic.php?p=452698#452698 Ceramic caps are highly unlikely to be damaged by reverse voltage.

That is correct about the transistors.... mostly. Sometimes BJTs will work "backwards", just not as efficiently. That said, it shouldn't destroy them either.

There’s a way to slightly modify this pcb to add an external input for trigger and accent? lilpaula87 Mon, 12 Sep 2022 03:51:23 -0700 https://electro-music.com/forum/viewtopic.php?p=452511#452511 lol building that Rungler on stripboard sent me down a long rabbit hole of shift register sequencers and LFSR noise.

Anyway, with the benefit of actually understanding the circuit now:

This is what I finally got working. I'm sure I didn't invent in, but I sure couldn't find an easy solution that worked when I built it.

if you build it share how it sounds :)

I have not seen BCM matched transistors before thanks!

Very cool!

Can be nice if you use a VCO as the CLK but keep in mind that the output frequency will be a fair bit lower. PHOBoS Tue, 23 Mar 2021 08:39:25 -0700 https://electro-music.com/forum/viewtopic.php?p=448133#448133 Thank you for sharing the layouts

I like the combination of logic functions you chose for your Analog Logic design.

Wanted to check that the inverters are separate from the logic not serial. So logic function outputs are not inverted.
