You have 64 tracks. Sixty. Four. I wouldn’t worry about tracks being such a scarce resource.
Personally I use the following layout:
BankA ( 16 tracks ) is for Drums. within those tracks I have certain instruments that are by themselves on that track, because I want to be able to mute them ( Kick, snare, clap, whatever ) and other that are on the same track, but with variations in the patterns of that track. For example the 3-4 sounds of a conga are on the same track because it doesn’t make sense to mute those separately.
BankB is for synths. I usually cluster track together by use, and sometimes dedicate 2 tracks to the same instrument, so I can have overlays ( core notes on a primary track, alternate flourishes on an overlay, so I can use a differen length or completely different MidiFX )
My default layout is:
BankA: drums and percussion
BankC: overflow from A/B
BankD: WIP and non-performance related items ( like tuning for analog voices )
Do you often run out of tracks in your projects?
