Impressive stuff. Makes me feel very old…
My own biggest problem with doing this kind of thing is when I return to the projects and delve into each bank/pattern days/weeks/months later, I have so far not evolved any way to remember what the hell I did on each track. Even finding favourite patterns amongst the banks is tough. I at least decided to always relate key to bank (e.g. bank A is always going to be in Am, bank B in Bm and so on), which helps, but how do people usually remember all this stuff? Maybe I make too many patterns… just can’t stop though.
