Does JJ OS2 compatible with Akaï OS pgm files

Do JJ OS2 and Akaï OS share same pgm files specifications ?

If not, does JJ OS2 import correctly Akaï OS pgm files ?
Does JJ OS2 store pgm files with a different format (so that there are not compatible with Akaï OS ?

ive had no problems loading programs with jjos2 from either the 2500 supplied CF card, or from my 2000xl

Ok, but I would expect some differences because, for example, only 3 layers are available on JJOS2 instead of 4 on Akaï one. They are also other program parameter differences between the two OS.

Do you think JJOS2 manages the differences ?

If you load up os1 or akai pgm's into os2 youll have to mess around with amp and filter envelopes to get stuff sounding the same.

certain features arent there too: 4th sample layer,velocity> sample start and velocity> attack for example. The work around is to use simult pads if you want to do these things.
