Here is a real no brainer example.
D:\bb\RealTracks\Guitar, Acoustic, Strumming Hank Sw 120\AcG011.wav
is made into a SFZ AcG011.sfz
(same as in C:\Program Files\PG Music Inc\Band-in-a-Box Sounds\Programs)
and dragged into Sforzando VSTi,
it plays instantly from one chord section in the RT wav file to another triggered by midi notes. No wav files were hurt in this demo, no copies were made, no wav files were created.
The project just saves the section play data, when the project is reopened it will instantly play from any bar.
This is what the BBPlugin can do.
