Hi bobby555!
"Pad one is in G key when it should be C"
You can set your pads in the MCC
"Are there no drums in the 5000 pre-sets?"
Launch Analog Lab, click on the 'Type' column and scroll to 'Percussive'
"When I load MCC, get no sound"
The MCC is not a virtual instrument, it's a software to setup your MIDI keyboard; so it's totally normal it doesn't produce any sounds if you hit a key or a pad when using the MCC.
"I cannot use with sonar 1"
We only ensure the compatibility of our soft from Sonar X2.
Hope I answered all your questions.
Best,
J.
