Frequency shifter pinging
Posted: Sun Nov 19, 2023 5:08 am
Another technique demo. Many people who do modular synth stuff know that you can "ping" a (usually analog) filter, where you crank up the resonance on a low pass or bandpass or whatever you like filter and smack the audio input with a short voltage burst (like a trigger from a clock) and use the sound to make kick drums or weird bells or other synth voices.
You can also do that with phasers too. And, as I found out the other day, a frequency shifter can do it too, if you turn up the regeneration a little. In fact, I'm starting to suspect that a LOT of things that have resonance or feedback can be dialed in to ping - much how Karplus-Strong sounds can easily be made by pinging a ridiculously short delay with lots of feedback.
Anyway, here's a minute of stupid robot noises.
