Simply the possibility to mute what is recorded by the mapping. As I think about it, I could mute the parent track right?
Muting the parent track stops recording. But lowering the gain volume of the parent track is a kind of switching monitoring off. I always hear an echo during recording. The signal is delayed because of the latency, and at the same time, I can hear the signal, my external soundcard produces.
It is on purpose, but I have often thought that it probably would be better to mute playback if it was being recorded over anyway.
May I ask why you decided to do so? I mean, recording several takes is quite difficult when you hear your former mistakes during recording.
Just my 2 cents..
