Skipping to the end of your last post, I thought it was interesting when you mentioned BIAB as a possibility. So I did as you suggested and checked 'Midi Option > Output Sync/Start info'. I think what you mean is that BIAB can sync with Vielklang just as it can with any VSTi synth. I loaded Vielklang choosing 'Add VSTi plugin' from the 'Default Synth Plugin' drop-down list (the same one with CoyoteWT & SampleTank). I got the interface of Vielklang to pop-up. The curious thing is when I loaded my WAV file into Vielklang and clicked Play in BIAB, my WAV file began to play - clearly, no distortion - BUT it would ONLY play the first measure! It would then repeat for as long as I let BIAB play - looping that first measure of the WAV file! I can even edit the vocal notes as usual but they don't make a sound. Also, I can't turn off the 'Link Playback to Host' (the short chain links on the interface) so I can't play/pause the file from within Vielklang.

Also, unlike the RB setup where I got the Harmony button to work, it would not work in BIAB. Perhaps I'm doing something wrong or setting up something wrong.

Any thoughts as to how we might be able to use this info to totally edit & harmonize the WAV file? Does anyone have an opinion?

I think this could be important. I am close to dropping this in favor of using a regular daw tho. Any thoughts as to which one I mentioned above might be best? Slaving clocks via a vst host etc. might not be the best way to go.
