This unit has a lot of nice features, such as the ability to record several tracks to stereo at once, bounce tracks, etc. It also has some great mastering presets for several different types of music, and decent effects. It also auto-assigns effects based on the type of recording you select, i.e., vocal, multi-track, etc. Unlike some other manufacturers, Roland has included printed versions of their instruction manuals for this unit.
The main problem I have with the unit is the difficulty of setting different effects for different channels. It isn't as easy as calling up a channel and selecting an effect. It is designed more for those who like to apply the effect when recording the track. Maybe a future software update will correct this.
The other glaring omission is a standard USB port. It has a USB-B port for connection to a PC, but a standard USB port with the capability of saving to a flash drive would have been nice. If you want to save an individual song, you must use the CD writer, which supports CD-R and CR-RW disks. You can also download all your folders to your PC via the USB-B port, but it's either all or nothing at all.
I'm still learning the unit, and will hopefully learn the tips and tricks needed to get the most out of it.
