Hi Leigh,

I've gotten LV2 hosts working on my computer, so I've tested it further,
fixed it, and optimized it some. Should work perfectly (although I've
noticed that qtractor seems to do a bad job generating GUIs for enumeration
controls).

One more thing: It has a hard cutoff, which I'm not sure is desirable for
the stutter effect. Should it fade in and out very quickly to remove the
"popping" effect, or is that part of the effect?

Thanks,

That does help.

I've fixed the syntax errors in the ttl. =A0If you could try it again,<=

that would be nice.

Thanks -- it opens in Ardour now, but with the mix control at 100% I get no=
sound out. I've tried it on both mono and stereo tracks. Adjusting the=
mix control back gives me some of the original signal, but still no stutte=

Thanks
