Am I correct in assuming that because Finale 27 (Windows 11) uses the Expression assigned instrument to play back such things as dynamics, etc., that assigning multiple samples to different layers is superfluous because in essence, all human playback will result through the sample (instrument) assigned to the expression layer in the score layout section. If this is the case, they why allow different assignments in the layers in the first place? I would prefer different instruments assignments to the layers corresponding to the voices, say for example, alto-sax1 and alto-sax2, but if it just reverts to the afore mentioned expressions layer assignment, then is there a work around, or are you just left with one instrument per staff assignable to be able to manipulate with human playback?
