I have two different 64-bit LINUX MINT machines with Grand Orgue installed - both interface properly with a MIDI Sport MIDI UNO connected to a keyboard. I have even tested for proper playing with MIDITZER and both work fine. With Grand Orgue, however, one machine plays notes properly, with NOTE ON and NOTE OFF working as expected, but the other machine machine only responds with NOTE ON and they remain stuck ON. I have examined the Audio/MIDI setups and they appear to be the same. Can anyone help solve this problem?
Also - both machines will correctly respond to "Play MIDI" using a MIDI sequence .mid file - no stuck notes
