Show Cue System

I am trying to use a digital audio console (Digico D1) to control SCS. I can control the hot keys easily, and can get the show to start using Midi channel 128 as the GO button, but every time I press the button again the screen just flashes rather than activating the GO button and playing the next cue. I sure this is something I have done wrong in the setup, but can't find any info elsewhere on the forum.

Can anyone help?

Further to the above, I have noticed that the desk outputs midi info as 1-128. If SCS is set to receive as 1-128, when you send value 128 (Go Command) it sees it as play cue 128. If you set SCS to receive 0-127, then send from the desk as 1 ( still sending in 1-128 format), SCS sees this as 0 and will fire the Go Command. In short, it appears that SCS is not recognising value 128 as the Go Command... Is there anything you can do about this Mike?

Cheers...
