In the mixer and arrange page, track mutes that you want to stay muted gets unmute after you solo/unsolo another track.
For example, if you just want to mute a couple of tracks for the time being and decide to solo another track, when you unsolo that track, the tracks you want muted from before get unmuted.
I dont want to mute the regions to have the parts not play, i’d like to use the mute buttons and have them stay muted.
thanks for your report. I just checked it back with Cubase and you are absolutely right. I entered it into our issue tracker and hope that we can address it soon.
