Re: Integrating the BCR2000 with the Korg DW6000

Thanks for a great program. Tried it today after watching the video and it worked within 1 minute of turning on the BCR and me not knowing what I was doing.
This has taken the synth to a new level. I now have immediate control like my other knobby synths. I don't have to think what I am doing now. Just turn any knob for a random unknown effect. 
Thanks heaps Royce.
