Hello, is it possible to send A4 track 1/2 indivijual to octatrack track 1 and a4 track 3/4 with master out ? And if i sent 1/2 with indivijual out can i acess fx buss slot and then sent it to octa ?
Yes and yes.
A4 track outs are all stereo so you can only send all 4 to the OT in mono or just 2 in stereo.
A4 track routing has options for bypassing the main bus and for bypassing the FX bus. default is that all tracks go to FX -> track outs / main.
