hi there
I have this problem, for example, I have two midi tracks, a bass and a drum
everything works fine no track is in freeze and all outputs and inputs are set properly
But for example when I double-click on the bass midi track the sound from the drum track disappear while i need to hear both. I 've tried to activate and deactivate the loudspeaker icon but the error persist
all cubase projects now have the same problem
please help !!!
i use cubase 5 and windows
thx bye

 

In pianoroll: Press S, as in solo/unsolo. Maybe it will help.

 

now it works !!!!
Thank you Baxter !!!! from the bottom of my heart
