I've just installed GPO4.
I've noticed that playing GPO4 as a plugin, I cannot get auto legato to work. Whenever I turn it on there is no sound coming out of the instrument I've chosen. The dial button for note length changes to 0% in the "Instrument Controls" section. Why is that?
Edit: In the stand-alone mode the auto legato feature works but strangely the instruments sound more legato when this feature is off than when it is on.
When AL is turned on polyphony is not possible, as should be.
