I’ve searched the forums but i have not found something related to this.
when recording it is very useful to change the phase of the track, to see if we have misplacen the mic, because it is cancelling signals.
and when mixing, you can hear if you have messed the stereo image when your mono is messed too.
we can always make a mono bus, and send it to the master (and make a template with it), but hey, it would be awesome to have a button to hear master in mono, or to change the phase (in a track) from the mixer.
The mono button can be very easy to implement, just move the panning of the master to center… while the phase button may be a little more tricky (add to automation? in stereo tracks, 1 button per channel? ).
what do you think?
