Issues faced:
Initially, I couldn’t get each different “button” to play a different tune. Whenever i hovered over the area it would just play the same 1 track.

So I decided to open the pPix patcher and realized that I could change the outlet square to r Step(number), which then connects to the various tracks.

Another issue is that the tracks played are only once, it doesn’t go on repeat until i remove the toggle. :-( Also, the areas are quite sensitive so other tracks may be triggered unintentionally.
