I just reinstated 6 song files that dated back as far as 3 years ago on Mezzo 3.6 - 4.03 spread across 3-9 gig removable drives to 1-18 gig removable and 1-80 gig firewire drive, for a Pop record to be recorded on Pro-Tools 5.1.1 with Mezzo 4.1. with a Sony DDS 4 as the tape drive. Without excetion all files/fades/mixs/audio etc.. loaded, played back and were perfect recalls from years past. I can't be more pleased!!!!!! Great Job Mezzo !!!!!!!
