Big thanks to all the Team for the wonderful piece of software. Testing midis with my A2 ZS + Airfont 340 (78 Mb), I found strange behaviour, like some instruments pushes out others (as if there not enough channels). For example a title track from 'The Secret of Monkey Island' sometimes lacks flute. This can be fixed by Settings -> Synth Compatibility -> Check Legacy Release/Decay. Is this sound bank or driver issue? Other banks seems to be Ok, so I'm unsure.
