Thanks Cyrille! It was my stupid soundcard. My Asus/AMD motherboard uses an integrated VIA VT2020 audio chip. Utter crap. I switched to my iMic USB interface, which has a Phillips UDA1325H/104 or /106 chip. *Clean as a whistle!! * I can't believe I've been dealing with that for 4khz whine (unde

[PD] pmpd output in audio rate

Hello list - and Cyrille, I'm trying to use [pmpd] to produce an audio rate output, but am having some unexpected results. To test it, I'm adapting the patch 69_pmpd_for_audio, by replacing the pmpd content with the one from the patch 50_string~ (I think the adaptation is correct). The re

Yes did that once, but I lost it years ago (the patch I mean) IIRC its not that hard. Use a [timer] and onset/tone detector, and an array that looks up the next state. You need a way to navigate a tree - a state machine with 26 terminal nodes (36 if you want numbers) and there are four symbols t
