I miss those old sorts of patch sheets. Keyboard magazine always ran a couple of them every month. I think they taught me a lot about synthesis! They also taught me about synths I didn’t own, as I could see an instrument’s parameters listed. There was always a sense of excitement with the arrival of each issue, hoping they’d have a patch for a synth I owned.
Occasionally, the magazines went even further, with actual software code for the reader to copy down. Sometimes it would be months before any erroneous line of code my be corrected in a follow-up issue! I was never clever or patient enough to try that stuff.
