Hi Kassen!

Hi Ge, long time no read, hope you are well!

I wasn't able to reproduce the denormalization symptoms even with a
much smaller feedback gain (.1 and .001), and looking through the
code for Delay and Envelope didn't raise any immediate red (or
orange) flags.

That's odd, I was able to spike the CPU, then take it out again with a HID command so I would be very surprised if that CPU spike came from anything else. Also; I didn't see any spikes at all untill I added this delay/ envelope combo to my code.

Perhaps my Pentium4 deals with this matter differently then your Mac? This would be a issue where CPU architecture matters quite a bit, I imagine.

  However, the gain on the Envelope itself is an
unchecked multiplicant.  I've added the check to de-denormalize on
that gain, which means it should affect all UGen.gain.  Hopefully
this will keep things under control.  The fixed version is in CVS.

Ok. Then I'll keep this code like this and get into the habbit of manually switching off the feedback every once in a while and see wether the update fixes this.

BTW, I don't think I saw a reply from you on those issues (from a while back) with array instantiations and larger arays of Ugens in classes yet, did you perhaps find some time to look into those as well?

Thanks,
Kas.
