Now I have seen >your recording, and have applied some brain power to it it's obvious what >I did wrong, and how to fix it. now i've seen your code i know where a good deal of what i have called aliasing is from. :) did you mean to start the sample loop at index 1 in crossover_dist_1404.xml? 0 sounds much better. i'm afraid it still aliases a little, but it does look like it's basically doing the right thing iiutc. the problem with both the valve and the xover i think is that the further you drive them, the edgier the discontinuity gets. it would have to be computed at sub-sample resolution, and interpolated in a band- limited fashion for the real 'hard driving' i think. my reasoning is that the problem we are facing here is the same as in the generation of band-limited square (or sawtooth, if you will) oscillation. tim
