Weird Program Behaviour - Dependent on How Patches are Switched...!?

Well, here's a weird one.  I would be happy if other Pro3 users could take a moment and see if their synths have the same behaviour.

I notice when I play program F7 P23 (Paraphonic Baroque) it will play differently depending on how I select the program.

- If I select the program P23 by turning the program wheel from either side - P22 (Vintage A.R.P-eggio) or from P24 (Grade School Musical) - it will play fine.

- But, if I physically play program P22 first (Vintage A.R.P-eggio), and then select P23  (Paraphonic Baroque) it will play all "wrong" and sound off.   

I have no idea if this is happening with any other programs, as it would be exhausting to try and find out what programs are playing correct and which are not depending on how they're selected.

Any ideas?  Is the patch corrupted?  Or is it how voices are handled during program changes...?  I tried reloading all the factory patches via sysex and it still occurs...

Very strange.

Thank you for letting me know.   I am hoping it's a "program" problem rather than a "hardware" problem.

(I should also add, when P23 (Paraphonic Baroque) misbehaves, there are two variations of misbehavior.  Most of the time it sounds as if one of the oscillators octave settings has suddenly dropped in pitch.  But occasionally P23 will sound like an out of control distorted, screeching sound. )

Have you reported this to Sequential support? The fact that you can show clear steps to reproduce the bug will help them to diagnose and fix it quicker.

Hi, yes I did report this to them.

I have read a bit about other's programs starting "distorted".  I wonder if this is somehow related.  Perhaps it is how programs are handled with the firmware....?

I'm hoping it can be solved....

(Sequential did confirm it's a bug in the OS...)

Hopefully get a fix in a firmware update someday.
