In this instance the new clarinet staff should be assigned channel 3 rather than reordering all the channel numbers. This would require saving the channel number to the MuseScore file as you mention in solution 1 below.

This is the traditional method. Keep in mind that MIDI is limited to 16 channels per bank/port. So you would also need to save a bank number in the file and display it in the UI in order to allow more than sixteen instrument per score.

I don't have enough experience working with external synths to know the disadvantages of option 2. Would all synthesizers/samplers support this method? Are there limits to the number of ports synthesizers/samplers might support? If the user changed the staff name in the score would that trigger a new automatic naming of the port and break the Jack audio connection for that staff? If so, that would be unexpected (and undesirable) for the user. David ------------------------------------------------------------------------------ Time is money. Stop wasting it!
