Hi, got jj os 2 up and running, just to find that when I load existing projects(created in os 1), they are all messed up: notes are out of tune or samples replaced by others. It mainly seems to affect tracks recorded from programs with multisampled instruments, which I play from an external keyboard(notes aligned from 35-98 is understood). I think the messed up melody-lines etc. might have to do with some midi setting, and could be just a simple thing that I've overlooked??? Haven't found any similar reports either..
Help anyone?
The programs as such work fine in both os, both on the pads and the controller, the trouble starts as soon as I record something and load it in the other os. Another example is I record a simple piano track in os2, then load it in 1 to find that this time the tune is unchanged, but the attack has been changed to sound anything but a piano(without that I would have made any settings for this in either system..!)
I thought the two OS were fully compatible(and I like aspects of both, so had hoped to be able to pick the best of both worlds), but it seems like it's not THAT simple?
Any help would be much appreciated, thanks.

There“s even some problems with compatibility within JJ OS 1, at least on the MPC 1000. I had to downgrade cause all my realtime info regarding levels, and if I remember correctly tuning, where off when I got a later version of JJ OS 1 than the one I had tweaked all my stuff in (4.15).
Previous parameters were switched to different filter parameters and the values were all wrong.

Downgraded, kept working until stuff was finished, mixed and recorded, upgraded.
