I realized I missed the forest (overall impact on the program) for the trees (the monthly updates). I'm doing a seminar on Amp Sims at AES, so I opened a Powerpoint for an amp sim workshop I did at GearFest two years ago, in the summer of 2014. I figured I could just re-use the Powerpoint.
But then I noticed how much of it had to be revised due to changes in SONAR. The section on using buses to do multiband processing - no longer valid, because now I use the much simpler Aux Tracks. Using the Sonitus Multiband to serve as a crossover for multiband distortion - gone, now that we have the linear-phase LP MB. Grouping the various multiband track outputs for comparisons - gone, now that we have Smart Swipe. All the screen shots with TH2 - gone, now we have TH3. The convoluted technique for rendering in a separate project at higher sample rates, then sample-rate converting downward - gone, now that we have upsampling.
What I saw was that in the past two years, my workflow had changed
significantly for working with amp sims...but I hadn't really noticed it, because it was a change here, and a change there. When Rolling Updates were introduced,
in theory it was going to be easier to absorb periodic changes rather than absorb a large number of changes at once. This was the first time I fully realized that in practice, at least for me when dealing with amp sims, that theory was borne out.
