hi Anand,
Steps 1-4 are correct (btw it's n27 file -not n12)
No matter what you will select or deselect in YEM (for Genos2), that won't change MSB/LSB values and so everything should work as it did on Genos1. Of course, if you forget to select particular voice or style that's used in some registration, then registration won't work anymore.
Short explanation about MSB-LSB-PCn values change... These values (which serve as voice ID) can change (or not) only when we import pack into YEM. Once pack is imported, these values don't change anymore. However, if we move certain voice from one pack to another, values can change (or not).
Let me explain about "can change (or not)":
1. MSB value never changes
-numbers 62 and 63 are reserved for voices created by user (62=drumkit, 63=normal voice). Voices in most Yamaha packs use other (reserved) values and that's the reason why (in YEM) we can only see (and change) LSB and PCn value for voices which have MSB value 62 or 63.
2. LSB value can only change (at pack import) if voice has MSB value 62 or 63.
-what LSB value will be assigned to certain voice depends on at what point the pack was imported. Let's say you already have three packs installed in YEM and then you install a fourth pack (which contain voices with MSB=62 or 63): to all those voices value 4 will be assigned to LSB -because it's 4th installed pack.
The only way to change LSB values (i.e from 4 to 2) is, if we install the pack as second in the row, or if we import voices from that pack into existing second pack.
Obviously, if we have only four packs installed, we can't change LSB value to 5. The only way to do that is, to create new 5th (empty) pack and import voices in that pack.
I hope that was informative for some
