Thanks for the reply ckobu and Chris !!!
I saw the video ckobu and that is what i' m asking ... also Chris i found figured it out that Yamaha packs have fixed msb/lsb/prg and you can't change that in YEM. But what happens when you install the packs in first place
Here's an example !!!
I had the pre installed packs in my sx700 and I've done some changes with voices and styles and registrations when i first got the instrument ... so after some time i made a pack with Balkan and Greek Turkish expansions so everything was in the instruments memory gone !!!
In YEM Balkan was on LSB 0 and Greek Turkish LSB 1 ... everything ok !!! Done some work again ... but now i decide to install again the Europe and Oriental packs that was pre installed in the instrument before !!! Doing that in YEM i have Balkan LSB 0 Greek Turkish LSB 1 (as before) and then the other packs takes the next number (Europe LSB 2, Oriental LSB 3) OK !!!
The thing is whats happening with the work I've done before... how can i find in with LSB was the pack when it was first installed in the instruments memory (now in YEM 2 and 3) so the work I've done before still works !!!
That is what i don't understand ... the relation between the YEM LSB slots 0 1 2 3 ... 127 and the instruments MSB LSB PRG !!!
Thanks for your help !!!
Spiros !!!!!!
