Zero Copy
I've been doing some tests and I've been surprised.
If the session is from scratch, without templates: the sends between buses are done!!! However, they show the following peculiarities.
1) The Master Default bus only supports sending, not receiving.
2) The incoming signal goes directly to the track, it skips the fader and the volumeter. The output signal skips the fader, the volumeter works.
Similar problems were experienced during the development of the new AuxSend. Maybe there was a solution here too.
