I also agree the Sonic Cell is a great quality unit..with a couple exceptions, I would have kept it longer..
The audio/midi interface is great..as is the mic preamp and effects..

My problems were the limited storage file storage to the USB device[no matter what size thumb-drive..99 files...and the loss of effects on the mic..every time a song starts..

Just a couple improvements on these items and I would revisit the Sonic Cell again..
