By accident I see that it is possible to assign the same trigger point to different parts… however they do not repeat… Is this meant to work this way? It jumps from Chorus to verse.
I personally think, fader levels should also NOT allowed / parts. Therefore we use track automation from the age of tape machines could record fader movements. Although DAW-style-automation is in the making for future development, levels can be set via vMIDI, as song is runnung already. Let things to behave so unconsolidated (like ch level / part, or channel-order/part) can end up in unwanted further problems and headaches.
This is my opinion only, but I think it seriously.
