I use a copy of each channel strip on paper and mark all of the locations of settings on the knobs with a pen.
For each track recorded I number a line on the page and make any pertinant notes such as what keyboard patches used, any dynamics settings,
effect settings, or anything else I might find useful for a future re-mix.
It's tough to remember all of this crap five years after the fact. Mounting a tape with only a track assignment sheet pretty much starts you at square one for a re-mix. The above information could get me in the ball park with only minor adjustments (or major adjustments if desired). At any rate, it provides a reference for a starting point instead of starting from scratch.
