Bill have a read on the motif forums--it is one of the BIGGEST complaints users have for the Motif keyboards - even the XF!! Yamahas reason is that it is all the insert effects and other sound specific data that needs to get loaded with the sound that causes it..Funny that it still does it with NO insert efx, and a bog standard no system efx sound too hey

The PA is quite good at sustaining when you change a patch as it holds the last notes played until the notes or sustain pedal are released.

There can still be some issues with midis though...but mostly minor, and usually a programming error...
