Re: A-rate vs K-rate

Yup, Josep beat me to it. We got great performance with krate between
100-440, and lots of use of the upsamp and interp opcodes. They work
amazingly well. And if you are doing a lot of modulation math ( ie envelopes
modulating lfos and patch settings ) the savings are very significant
between doing the math at krate and then interpolating at the very end on
only the final applied variable, vs doing all the math with higher krate
variables or even arate variables.

Does this make sense? If not I can find an example around here and post it.
