I'm running P5 (Prophet5) on Windows 10 in Studio One. All 3 are 100% up to date. (Even graphics card)
I run a multi-monitor set-up.
1) Studio one running.
2) P5 Running in S1 Instrument Window.
3) P5 can be alone or tabbed with other VST in the Instrument Window.
4) If S1 Instrument window (tabbed or un-tabbed) STAYS on the Main monitor with S1, all runs as expected....happy camper.
5) If I move the S1 Instrument window (tabbed or un-tabbed) to the other monitor AND then switch tracks in S1....I get an S1 app hang.
6) Task Kill.
7) Only happens with P5 in S1----Cubase does not do this.
