Garageband, Motu 828 And Getting Audio Out Options

[R-Man]

I have found that the easiest way way for me to set up the drum backings that I need is to utilize the GB drum loops and jam packs. Love it.

Now I want to send my loop out to another device (BOSS BR-864) to use as a fast portable practice tool.

I would prefer not to export an MP3 which is the only thing I know how to do.

Is there another, or better way for me to send the audio out and into my BOSS?

My setup is: MOTU 828 and Garageband

Help, please! Thank you!
