You should ask this company your testing for.
I downloaded the KT Trigger and it looks like a big waste of time, typical of freeware.
It does what Audio Snap does with a sketchy GUI, It is as I thought, just for drums or transient sounds.
I read the instructions and they point at using Cubase. They say there's a list of DAWs that don't support it but the link is dead. My guess is Sonar is one of them. It said the output of the VST will now show as an Input to any MIDI track, Nope, not there.
Pitch to MIDI for non percussive material is a hard one, and to date, Melodyn Seems to be the the most recommended. A free ware plug in that does this would be dreaming. Melodyn now comes built into Studio 1.
