Hi !

Just set up my gear after moving to a new house and I have a "little" trouble..
First here's my setup:
PC running under Windows 2000
Emu6400
Cubase VST 32
Emu master keyboard
Iomega Zip drive
Midiman 1X1 usb

So... when I load a track in Cubase and try to play it, any sounds from the sampler is played. The thing is when I play on the keyboard some samples are played even if I'm on chanel 1, 2, 3 ... or an audio channel as well. I checked my setup many times, trying to change Midi cables, checking the Cubase midi setup but anything is working... I don't understand cause it worked well before... Not sure on my cable setup though.. but normally it should be well done.

Anyone could help me?

Many thanks in advance Emu'smokerzz!

JP.
