Thanks @mechanic and @doctormojo
So I added a the toggle button as data source to the Layer Eject, marked it as 'Val from Input", and marked “Invert”. Works like a charm.
Same button used to trigger the clip.
Then repeated the same for all trigger buttons. Works great.
Will try imported TouchOSC control surface and see how that goes.
One other question relating to the mapping of buttons to clips.
As I am doing it now, the media bin “Triggers” simply seem to be in numerical order relative to the clips.
Is this the only way to assign these?
Seems quite limiting, and how would one assign more than one “Trigger” to a given clip?
