I noticed a difference between running a sketch from the GUI and as an exported application from the command line. Whatever MIDI library I use (javax.sound.midi, the MidiBus, ...), some MIDI devices are missing in the first case.

When I run the Basic example from MidiBus from the GUI, the output is:

Available MIDI Devices:

----------Input----------

[0] "Real Time Sequencer"

----------Output----------

[0] "UX16 [hw:1,0]"

[1] "Real Time Sequencer"

When I export the example as an application and run it from bash, I get:

Available MIDI Devices:

----------Input----------

[0] "UX16 [hw:1,0,0]"

[1] "Real Time Sequencer"

----------Output----------

[0] "Gervill"

[1] "UX16 [hw:1,0,0]"

[2] "Real Time Sequencer"

Why? Can I get all MIDI devices to be accessible when running a sketch from the GUI?

Thanks.
