Newest OS update for the Pro3 is pretty good [1.2.0.4].
The Morphing feature/function isn't convenient, but you can assign it any available knob. (I always use "Value")
So yes, morphing works great.
Though I find it easier to use the Touch Slider for X and the Mod wheel for Y (turning off the Vibrato) to achieve large changes to my patch.
But!, there are two system updates! 1: Main OS, and 2: Interface/Panel.
[*Do NOT update these systems lightly! You can brick your synth, or lose your patches!]
Check for updates from Sequential:
https://forum.sequential.com/index.php/board,40.0.htmlLast I've seen was, #1: the OS update (Pro3_Main_1.2.0.4),
and #2: an "interface update", Pro3Panel_v1.1.0.13.
Note: the panel updates can act very differently. The way they react to the panel dials, especially... - "Not switching all of the time." or "Switching values more than I turned the knob." (Sorry I can' t remember which is which.)
-- Also, when installing, make sure and wait for the update to finish!.. then wait more! It's slow.
Then verify it(!), because the whole Sysex thing is pretty weak and unreliable. I've lost patches.
