I went to a buddys place yesterday and had my first experience with his Boss Micro BR. I'm very impressed with the unit. We used this session to quickly put together a couple of new songs. We recorded a couple of guitar tracks direct, and then recorded the vocal. I dont think this type of unit can be beat for quickly putting together a demo. My friend has just got the unit, so it took us a while to figure out some of the functions. However, its pretty impressive that as soon as you're done, you have the mp3 available to do whatever you want with.
It wasnt clear to us if you can select a drum beat, and then record the drums as a track, or if the drum beats are only for jamming along with.
I will be picking one up soon. What do they sell for in Canadian music stores? He picked his up on Ebay.
