JJ OS Compatible with BlueBox???

I have not yet upgraded to the JJ OS but am planning to in a few minutes or tomorrow.

Is the JJ OS compatible with the BlueBox program for making MPC programs? That is if I create pgm files with BlueBox can they be read and used on the JJ OS and if I create pgm files on an MPC with JJ OS can they be read and edited on BlueBox?

Si.

i actually started looking into creating a bluebox type program for the mpc2500 the other day.. just out of sheer boredom.

the first i think 24 positions of the pgm file is a header record which includes the file format. blue box writes in MPC1000 PGM 1.00 format while the JJ OS for the 2500 now writes in MPC1000 PGM 1.01. the only thing that seems to be different is the slider data.

but since the file has that header record which tells it what format the file is in, all future OS's should be able to tell which format to use when loading the program by looking at that first line. they should be backwards compatible.
