Flash the Zaquencer firmware via MIDI as described in the 
documentation to your BCR2000.

Power the BCR2000 and read the challenge code.

Depending on the operating system you have on your computer
run either Zaquencer-auth.exe or Zaquencer-auth.linux in a 
command window and give the challenge code as argument.

Enter the displayed code using the BCR2000 encoders to 
authorize your sequencer.

Have fun!
