Aha – problem solved, I think. In Elements, access to the tempo of the track is via the Editor window for the track. If you set the tempo there, and then enable musical mode, the track then follows the project tempo; result…
(The underlying problem I was trying to solve here is “can’t export a metronome track from Cubase Elements”, which has been discussed quite widely before. The workaround of “use a MIDI metronome and route via a Group track” doesn’t work in Elements because you can’t set the input for an Audio track to be a Group track. So the track I was importing was a click track generated from an external program – in my case Audacity – which now follows the project tempo in Cubase, including the speed-up part way through. Export from Cubase, send back to project people who need the click track to work from, sorted. It had to be easier than recording the Cubase playback on my phone…)
