Sorry, the use case is manually connecting tracks, for example, I want to manipulate piano sounds through several stages, using a track for each stage: piano->piano_effects1->piano_effects2->piano_inserts->Master Rather than use buses, it would be easier to connect things this way: nama> piano_effects1 source piano or nama> piano send piano_effects1 The bit about assigning to buses is a detail to consider because any new track by default outputs to the mixer (Master), and that behavior is not wanted here.
