Some pads suddenly mute in Groove Agent

Suddenly, when I opened my project, a pad with a kick drum sample has become mute even if it’s not muted. I had to re-load the sample. I also tried some samples yesterday in other pads, and they worked but I didn’t save the drum kit. Now when I loaded those same samples to the same pads again, they won’t play. Is GA buggy? Or is there some setting that I’ve accidentally changed? (But everything seems OK, no muting, volume on, no filter etc.)

Hi,

Is the Pad muted, or is the Instrument Return muted by any chance? Do you use only one Instrument Return Channel, or multi-outputs?

No, the pad was not muted, and the buses were as before, when everything worked. NOw when I re-opened the project, the clap and the crash had become mute. The sample editor still shows they’re there. I tried loading a factory kit but GA got stuck and didn’t load it. I then discarded GA and loaded it again. Still frozen. Clearly it’s buggy. I guess I’ll have to put all my drums on separate audio tracks as GA can’t be trusted. UPDATE: Rebooting the computer without GA loaded in the project, and opening Cubase and loading GA worked: I could now load my kit and the samples were there (except the ones that disappeared earlier). I wonder what the cause of this behavior is.
