Thanks for your reply.
Do you have the 6.17 driver installed on your PC? Yes I have
If you connect to the PC, on the mixer panel do you see the device connected properly? It does
The display on the LP-16 shows PC interface mode? It also does
The interface seems to work well. I also hear the windows tune when I start up my PC. But when I start Ableton (32bit) it doesn’t regonize the audio driver and I have to choose the LP 16 as audio driver. Then the screen turns black and I haven to restart my computer.
When I first reinstall the firmware (32bit) on the LP 16 then there’s no problem.
I really don’t understand what’s going on.
