This is a great utility tool.

I use it for a variety of tasks.
• The analytical side is very useful and accurate.
• Creating sounds from scratch then loading into samplers is also a nice resource.
• File type changing* works where other apps fail.
*****
I found issues in the Pitch / Speed (speed section) where the resulting file becomes hash.
(I tried this with a variety of percentages without success)
Pitch works great.(As is the case for all the other manipulations I have tried so far.)
VST rack for applying multiple vst effects is nice as well. (Just set up the effect setting
Individually prior to applying from the rack)

Additional request would be:
• Auto batch convert ability.
• An auto interpolation of the in/ out points when effecting a portion of a file with the plugins.

A solid and useful app in OS 10.3.2
Well worth the appreciated price of admission.
Recommended for all sound designers to have in their arsenal.
