In that case there would be no difference to your criteria mentioned here opposed to the 2kxl, i would play with it as long as you can cuz you need to make that choice in the end.
In regards to names etc,... MPCEDITORV3!
In short my process in making a kit;
Open up SF8 and start adding markers, as many as I like.
Go to Special-> Region list -> Marker to regions-
Go to Tools-> Extract regions
Now you have a map with long filenames with region nrs. I'll rename them all at once with Total Commander (
http://www.ghisler.com/ ).
In TC, open the folder with the extracted regions and hit CTRL+A to select them all.
Then hit CTRL+M for the multi rename tool and the window appears.
[N] indicates the name for all the files, you dont touch the extension cuz thats allright. Keep in mind that the mpc2kxl only reads 8 characters so shorten the name to 6 letters and keep 2 letters free. Below the Name mask there a button that says counter but your can also just type [C] after [N] ( so thats " name[C] ". In the upperright corner of window you can define the counter, if you didnt create more than 100 files than set Digits to 2.
Hit start and itll be done in a sec.
Open up mpc editor, select the folder from browser and hit autoload and it will assign all wavs by number over all 64 pads. Save sounds and pgm to CF card drive and you're done.
This takes less than 3 minutes excluding creating the regions.
In regards to Pattern names, you can make templates of different setups...as you like and open them up for whatever situation is needed. You just need to organise your way of doing things live or like me just freestyle all the way ( i dont bother with naming patterns and sequences...not all the anyway).
