I'm not an amp modeling guru, but I do do programming. The algorithm being measurably more efficient is one thing. Getting it integrated into existing code to replace a bit is the trick, and likely where the optimization will be occurring. Likely once it's integrated well with the Amp block's code, the savings in CPU cycles will emerge....I thought the new method was inherently more efficient, and by a decent amount. Just curious why you need to optimize just to get back to par.
