Not to tape. To an 8 track direct to disc recorder. From which I send mics and keyboards and such through the Mackie into the Tascam.

All in the exploration of BIAB and RB. I don't know how to input into BIAB or RB yet. So I can feed back through my M-Audio MIDI interface and record into BIAB?

Never tried, never thought TO try, never looked at if it was possible. Old school guy I though BIAB was only output.
There is a difference between giving up and knowing when you've had enough.
