Little bug with native mpreverb [ONLY ON MAC]

once in a while I work in Renoise on a Macbook, and I’ve noticed a little bug with the mpreverb I thought I should mention,
if already not alarmed by others:

  • The mpreverb NEVER kills the verb 100%.
  • To test: put the dsp on a track with a sample, and insert a lot of empty lines/patterns afterwards.
  • If you have decent headphones you should notice the eternal low-volume sustain.

Should be replicable using default settings, or pretty much anything I think.
Renoise 2.8.0
OSX Mountain Lion
(was also like this before upgrading from Snow Leopard).
