i’ve not done this with an acoustic upright… only a steinberger upright and that was the best method i could find.
VA is hopeless on bass, well anything more than straight 8’s with a pick on an electric.
One of our guys has autotune and that seems to be pretty accurate with no detectable artifacts, again not tried it on an acoustic upright… just the steinberger.
I find also that if i switch a file to musical mode that i have tracked with my warwick (4string) or my spector 5 string that even without any tweaks the sound still seems to develop artifacts… not impressed with this at all.
Steiny SERIOUSLY need to get their time stretch sorted out, even cakewalk 8 back in 2000 or so had better time/pitch functionality. It’s even worse on my Ashbory mini-bass… as soon as i switch the file to musical mode it just warbles…
