Hi,
Normally a track only needs to be initialised if the type/steps/layers changes. You do need to confirm change of a layer though, by pressing GP10. The GP10 button and OLED will blink until you do so. Changing the layer type will delete track data for that layer. This makes sense in many cases, because the display and data type might be quite different.
But I don’t think you need to init. the track each time, just the layer if the type changes.
Hope that helps!
Best,
Andy
