Both don't work, and when they fail, they both fail at the same time in
the same way, with a note stuck on. That's why I titled the thread HDSP
MIDI In - stuck notes. (I'm actually using MIDI 0, not MIDI 1)
-> softsynth

HDSP MIDI 0 ------

-> HDSP MIDI 0 output -> external synth
Using the USB MIDI in does not fail:
-> softsynth
|
MidiSport 0 ------
|
-> HDSP MIDI 0 output -> external synth
