i don't think disconnecting it helped.

following the logic i was working with, i changed the buffer size on the maudio card and got the effect i wanted...

i can't upload this with a note to change the buffer size to 1024. not for the least reason that i don't understand *why*. but it's consistent across two cards. i don't get the right warble at other buffer sizes.

i'm slowly coming to the conclusion that i must be taking advantage of something unusual. i mean, i thought i was just driving the bass a little into the red. it seems to be something more complex than that underlying the effect. it may be out of phase or something.

i need to do a little research. i can't let this into the wild until i'm sure it's going to be audible at more than one buffer size.
