You know, actually, that isn't going to help performance at all. Whether you're making one calculation per sample or make ksmps calculations each k-rate, it's the same number of calculations. I don't think this is the answer. I've messed around with simply adjusting ksmps and tweaking the algorithms to account for the extra "time" inbetween each k-rate, but it sounds very different, even if you ignore the bit-crushing effect this has on the output. This requires some more thought.

Each k-rate pass, loop 1..ksmps to calculate the signal's effect. I'll try it and see how it works out. Thanks for the suggestion!

It's a bit much for me to grok at the moment with everything else spinning through my head and with the bit I'm looking at I'm not sure what performance gains that are to be had.
