You have called me “master” … ? …
As already said, the FX on this machine is quite unconventional. Would you mind to explain to me, what you exactly want to do?
One solution could be that you apply a FX on one track, re-record this track with the FX and then apply another FX to another track and re-record this as well.
The Tascam is not as well equipped like one of the digital mixing desks, which have a fat-channel and insert FX on each track.
