=== Detecting an automatic assign ===
Note, if automatic assign is used on a bank, the first note that is received on that channel is used to detect the new channel. This means Box Of Stops will need a moment to reconfigure itself around and associate the bank to the input channel.
Once this is done, the bank can start playing normally, but this does mean the first note or two you play will not sound. If this could be a problem, it may be best to explicitly assign the input.
