I use zero latency monitoring in my studio, so i dont use the monitor button in cubase. If i record something on a track, and then i put Melodyne on it (ARA, not insert), then if i re record something on this chanel, i hear the old recorded event during record. This is wery bad thing, i must mute the track, in the punch in point, like an idiot :).
If i use ARA melodyne on a track, then i dont see the level meter visual on the mixers.
If i use multiple layers of ARA melodynes, i hear a little random click on the cut. If i remove the melodyne, the click is gone, so there is no cutted waveform in the audio event. The click sounds evry time random volume, and random frequencies.
