Alternative for [T1–4] track keys not working on my A4

Hi everyone,
My T1, T3 and T4 keys are unfortunately not working anymore on my Analog Four… I’m looking for an alternative to switch to my other tracks (I can only switch between T2, FX and CV at the moment).
Do you have any idea ?
Thanks !

As far as I’m aware, there is no alternative shortcut.

If you don’t want to get the buttons repaired, consider it a 4 voice Polysynth on track 2 with a dedicated FX and CV track?

Did the problem appear suddenly and was the a4 in use all the time? Sometimes buttons can get sticky if they are not pushed for a long time. it could help to push them repeatedly to bring them back to life.
