More detailed info:

DK-ORCH (128-2-1) was changed in that it adds ROLLSNARE (103-9-1) at C#6. Very nice.

So I went back to real mode, and looked at the "sound" of DK-ORCH and verified that ROLLSNARE is selected at C#6. Then I noted all the paramters of DK-ORCH at C#6. Then I looked at ROLLSNARE through sound and noted all its parameters.

I went to SONG MODE and before pressing stop or playing anything, I noted that DK-ORCH plays correctly at C#6 and that all the parameters are identical.

Then I played Cubase and I noticed the change in sound and at the same time when playing from SK keyboard, it is playing that WRONG strange modified sound. I looked at the sound parameters of DK-ORCH at C#6 and ROLLSNARE at 103-9, they are still identical!!!!!!!!!

So if all internal parameters are identical, why SK decided to play the song differently?

I appreciate any help.
