As far as I am concerned Tascam kinda dropped the ball on the m 35 mixer.
They took the attitude that you wont just hook it up and leave it in any one confirguration so you must repatch after you have recorded your song.
They recomend you use the aux outputs 1 and 2 for your mix down.
Its a mixer that will do a lot but can be hard to learn. (even with the manual)
If you dont have a manual I suggest you get one.
It gives some suggestions on set up in it and can get you out of a bind when using the mixer..
I've read all the other threads here on the M35 and there has been a lot of wonderful posts by Reel and Ghost on this mixer.
One thing not touched on is how to get the signal routing so the pans on the channel strips function. As it is now I can only pan via the sub-master modules.
