Hello, i think i have found a process with no problem for SQ multitrack recording :first, thanks to tourtelot: i use a harddrive with an external power supply and second, after connecting the hard drive to my computer, i format the disk via SQ5 before recording. I made it a dozen times and it worked perfectly until now… i will give you some news after this summer to confirm this process… Bye.f6 onzeonze
