Bonjour, Stéphane,
A priori, tu peux te passer de Maestro. Voici ce que j'ai trouvé sur le site d'Apogee, ceci concerne la Duet, mais j'imagine que c'est pareil avec la One:
Do I need the Maestro Mixer?The Maestro mixer serves to provide a low latency monitoring mix while recording.
Therefore if you're using Duet to listen to iTunes or audio from another program, there's no
need to use the mixer. Set To Hardware to None to disable the mixer.
It's possible that the latency of your particular recording system is low enough to be
unnoticed. The system latency is determined by the recording software's buffer setting,
and if your Mac is powerful enough, it's possible to set the buffer to a lower value (shorter
latency) without encountering clicks and pops in the audio output. If the latency doesn't
pose a problem while recording, the mixer may be disabled by setting To Hardware to
None.
