I did some more testing and found the tuning issue seems to just be in the SF Chamber Strings patch d-Celli and specifically the legato setting. The "long" setting seems fine. Crazy, but those two settings playing the same note are 11 cents different in pitch. Enough you might not notice as a solo instrument, but put against anything else it starts to sound like an open mic orchestra, lol. In the two screenshots if you look at the Melodyne window, I highlighted the long F notes and you can see Melodyne analyzes the Legato F as -15 cents flat while the same MIDI note played through the Long setting is only -4 cents flat. Audio link in comments below. Has anyone else noticed this?
