a brief update:
1) i was referring to the sight reading exercise, not the melodic dictation.

2) after restarting the program, I discovered that the "infinite sustain" disappared when I set the MIDI IN transpose to any value, and then reset it to 0...

So there is a workaround, but some improvements ...

hello,
just bought and installed Ear Master Pro 6 on my iMac (Snow Leopard), and using it with a MIDI guitar + Roland GI-20, for sight reading, using the melodic dictation.

everything works, but it seems that no note off is detected, so the played notes have infinite sustain...

To be more precise ...
