Before changing the tempo, for each track, in the Inspector, you need to toggle the “quarter-note” icon, so that it becomes a “clock” icon (those tracks are now in Linear Timebase). Additionally, if you don’t want the audio Bass track to change, you also have to go into the Audio Pool, and make sure that Musical Mode is switched off for that audio file.
It seems that the problems rests with the version of Cubase that I am running. I only own LE 8, with a trial for Elements… sadly it seems I would need to upgrade beyond both these in order to have this function.
Tragic shame really. As I’m not sure how to get round this issue
No, that’s the track delay icon. You might need to enable display of the timebase toggle in track controls. Right click on a track control (the part where the record button and track name etc are grouped together on the left side of the arrange window) then go into track control settings, then add “toggle time base”.
