if i use the scope midi port in my win 8 64bit system with ableton64 (9.1) i got strange MIDI problems.
The first i discovered was that the midi clock timing was total unusuable.
So i have used one of my usb midi interfaces.
now i was playing around with push and my xbase09. i mapped the controllers via scope midi.
the result was there was a very high latancy of the parameter changes on the xbase to the ableton macros.
And it crashes ableton after some minutes. If i connect it to my USB midi interface it is working without latency and i have no crashes.
is there any known problem ?
cheers

PS;
the system is running fine in all other cases .. only wavedevice problem with more then 4gb ram and the MIDI problem.
