What's a good resource for synthesizing classic electronic music percussive sounds?

@porres this patch from @MikeMorenoDSP is great for synthesizing drum sounds (in my opinion - not sure if they are "classic electronic"): https://forum.pdpatchrepo.info/topic/12015/mymembrane-acoustic-drum-synthesizer

@porres Sound On Sounds Synth Secrets has some, it is widely available on the web as a PDF and I think they have also have it all on their website. The name of the series is rather misleading, it is more Synth Standards. Are you looking for particular sounds or just the general way various sounds were made?

The standard drum sound was almost always just a resonating filter fed a trigger or a decay envelope. These often had issues with feed through and the trigger would cause a thump or click throwing in an impact sound for free, sometimes they would send the trigger through a simple RC lowpass so they could tune the impact sound separate of the shell resonance tone created by the oscillating filter. Add in a white noise generator and it is a snare, many classics used just filtered noise for the snare. The standard circuit used by most of the classic drum machines was just Twin-Tee or Bridged-Tee bandpass stuck in the feedback loop of a gain element, should not be too difficult to mimic in PD, PAiA gives a decent run down on the circuit https://paia.com/syndrum/. That is most of the classic drum sounds right there, they got a little more complex by the time of the 808, but not much and much of the added complexity is just to deal with the less than ideal world of electronics. The other sounds tend to be multiple oscillators and/or white noise through differently tuned filters.

I can not give much in the way of resources, I learned from the schematics. For many of the more popular sounds like anything from an 808 or 909 and many others, you should be able to just search for something like "808 kick drum circuit analysis" and get a write on it that will lay out the signal flow and tuning and timing of the various parts, just need to read around all the electronics non-sense.

this is for a didactic goal and also maybe to provide some "classic" textbook sounds as objects, so not really into complex emulation and sophisticated recipes, more like basic general stuff... so yeah, looking for something generic that qualifies as a good "standard way of doing things"

anyay, a nice collection of pd patches that people regularly use should be welcome : )

@porres I like the d-808 objects in dlib https://github.com/damian0815/dlib
