You need to update your a4 to the current OS, it will activate the +Drive then you can save up to 128 Projects internally ( i would still recommend to back them up from time to time) . Using sysex isnt realy that painfull btw. :slight_smile: . Get c6 and the newest OS on the elektron site. Set your midi/usb wich is connected to the A4 via configure in c6. Set the A4 to recieve an OS update (global - OS update). Drop the OS file in c6 , highlight it and press send.

Backup your stuff works pretty much the same in the other direction, set c6 to recieve, send with the a4 (global - sysex dump).
