In a recent blog article, Kevin of diyelectromusic went to some lengths to look at using vactrols for a VCA with an ESP32 project.

I hadn’t intended on reading it all (https://diyelectromusic.wordpress.com/2024/04/20/esp32-dac-envelope-generator-part-2/) but then I opened my gob on mastodon before having done so and recognized, now I was done for. I’d have to see what he was actually up to. This can be quite involving. Kevin does a great job of documenting the minute details of the experimental procedure. Damn it.

This reading all got me thinking, as I use vactrols in my Keep synth and for tremollo effects all being purely analog applications … do I need to learn something on this front?

And the voltages are much higher than those Kevin has to work with. And, curiousity killed the cat.

Having neglected the blog, I thought I’d report what the analog Hd https://gieskes.nl/instruments/?file=analog-HD

sounds like when it meets the keep.

So, what’s up Doc?

Sometimes when you’re just digging about for a sample ….

No, I still do not really blog. I’m just practicing writing markdown to keep from forgetting it again.

So, what’s up Doc?

No, I still do not really blog. However, twice with in the span of 4 weeks, I saw the same puzzle pop up. Once on Hacker News with a neat let’s make a solution using Sympy as a solver and once, well, in typical newspaper fashion.

This is the oft used form:

I just don’t blog, now, do I. But I sometimes make a thing. Supercollider sequence.

I thought I’d make a note of the fact that I’m rebuilding the site :) Since I’ve begun posting material for the synths I’m building, it became apparent that much of the old site was not just dated. I’m dated :)
