JJOS data loss

hi

im considering switching to a JJOS but wanted to know if will lose data sequences, programms, samples etc that i have made on the original OS?

im sure this has probably been covered somewhere obn the forum before but i couldnt find anything relevant .. im using an MPC 1000 by the way , thanks

You won't loss anything by just switching OS. Some things may sound different, depend on which OS you will choose. Some things have changed thru all this time.. and it's not 100% compatible between versions.
