this Boss BR600 is designed as a scratchpad songwriting tool - so it has mono inputs (mic/line and a drumbox and effects built in - it does have a stereo mini-jack input which it says is used to input from things like a cd player, but i cant see anywhere whether it can record from this stereo inpout to 2 tracks at the same time (to record stereo line-in)
i'm not sure you are going to get any advantage from using the other equipment with the Boss unit, because the Boss BR600 has mic pre-amp already built in and guitar modelling-fx input already built in etc - it is designed to setup a drumtrack (preset or user-created), then records guitar/bass/mic layers one track at a time to create a demo song
it is not really designed to use as a standalone recorder with a mixer
the drumkit has it's own 'brain' unit (the box with the sounds in) and it may have midi out also, but the BR600 doesnt have midi IN, so you cant play the drumsounds in the BR600 to sequence them from the kit-pads
the problem is this selection of gear is a little mis-matched.
you could record your electronic drumkit playing IN to the BR600 as audio... to do that you need to select stereo LINE-INPUT recording on the BR600 and record to a stereo track
if you want to use the mixer you need to get or make a cable to connect the Mixer to the BR600
but why would you want to do that?
=================================
so - question:
what are you trying to to record? - or rather - how are you wanting to record?
either you want to:
A. record songs, by yourself - building the songs layer by layer playing everything yourself
B. record with some other people all playing different instruments at the same time - then add overdubs
which is it? answer that first please
