I have been using my Sonic cell module with BIAB for some time without problem since receiving the above tips. I have recently bought a new desk top computer to process and edit my music. It is a Toshiba with Windows 7, 64 bit operating system which is the same as my lap top that I have used for perfrmance with Sonic Cell. When playing songs that have both midi and audio parts the song distorts, slows down and misses complete bars. I have tried reinstalling the drivers several times but I can not find a solution. Has anyone had similar problems and do they know of fix? Your advice would be greatly appreciated.
