Hello, yes MSB/LSB a different on OS 2.0 than on OS 1.6, due to the fact that new 99 peformances are "insert" in the first presets banks (number 2 for the first to 786 for the last) and also because the preset banks pass from 16 to 32 on OS 2.00.
There is presets in bank 17th, 18 to 32 are empty actualy.

On OS 2.0 MSB 63 / LSB from 0 to 79 are for single part performances and MSB 64 LSB 0 à 79 for multi part performances.

MSB/LSB for Live set do not change, if you use them like me for stage, don't worry, they are the same.

Check Phil Clendeninn Namm Live video, he present John Melas Performance Editor and Total Librarian, you will see the 32 preset banks on he' s Performance Editor presentation :

You can find on my site Moessieurs the dedicated page for OS 2.00, it's in French but you can use the google translator tool in top banner to translate in your native language, not perfect but enough good to understand the general meaning.

http://www.moessieurs.com/os-200.html

There is in pdf the list of the new performances and where they are as "number", and a pdf with MSB/LSB/PC for OS 2.00.

There is also 3 Instruments definition file (ins, .txt and .midnam).

They are done with also my users and library "list" too, sorry not enough time in this moment to rework them and delete myusers and Library "list" , you can use them on 7 february when OS 2.00 will be released for presets management on your favorite daw.

Hope it's help.

@ Johan

Sorry, I do not have more information than you on this update.

I do not have the datalist version 2.0

( And I can't adapt my utility until 7 February. It's not just the program changes that will change)
