Mikey, going straight into recorder sounds nice but a few things to keep in mind: (1) the 38 operates at -10dbv so make sure your outboard gear (preamp etc...) is compatible or can be switched. Make also certain that you have the proper cables; (2) you'll need a way to monitor your work while recording or overdubbing, no matter if you're recording 1 or more tracks at a time and thus something basic, even like a headphone amp, would help or maybe your roland can be setup that way. I dunno. Ideally you should get a 4 bus mixer, at least down the road. I don't know about current, modern mixers but ones from TASCAM would be nice.
I think if your album is good and your live act is even better... that's when you know you're listening to one of the greatest musicians/bands of all time.
