Hello Andrew,

Thanks for your reply. For Midi Playback I use both Midi-Out of the UA-700 connected to my Roland EXR-5 keyboard or the Microsoft GS Wavetable Synth (under Windows 7 64 bits)
Crashes occur on both and also when choosing MME.

When starting RB now as soon as I want to select the UA-700 under ASIO Audio Drivers dialog (pops up automatically now when starting RB) a violation error occurs saying :

"Access violation at address 100025B9 in module 'Rdaw1024.dll'Read of address 00000108 at: 100025B9"

After the violation error RB sends the following message :

"Card failed Test Record/Playback. Full Duplex setting in Options | Preferences | Audio Settings Dialog has been disabled Contact Manufacturer for updated driver (if available)"
After this message there are no drivers listed anymore under Midi-In and only Midi Mapper and Microsoft GS Wavetable Synth under Midi-Out.

(Usually there is also both UA-700 Midi-In and Midi-Out available)
