When I was young, and couldn't afford the £80 or so for a synth cartridge full of 50 new
sounds, one for the principle new sources for sounds was they'd print the patch charts of
a new sound in a magazine.
If one month it happened to feature a synth I owned
- free patch! I reckon I got, over a few years, at least 6 new patches that way! Maybe
even 7...
