hhs, sam: That's strange, must be something to do with DXi, Direct X version, Windows Media Player version, CPU chip etc.
We'll sort that out, but in the meantime, try re-enabling the fast generation, confirming that you have build 291 (Help-About), and try using a DXi like VSC-DXi (Options-MIDI Drivers). If all that doesn't work, disable the fast generation.




Peter, as I said, everything works great on my new Win 7, i7 10G RAM system - incredibly fast as well - RT are almost instant! It was when I connected the drive to my slower XP system in my studio that the problems occurred. I did confirm that 291 was installed and re-enabled, no help. I'll try using DXi instead of my hardware MIDI interface and let you know tomorrow when I return if that works.
