Using Mainstage to control DMXIS

I am using MS for my cover band.

I have a midi foot controller attached which scrolls the songs (patches), and it also controls the on/off guitar effects pedals (HIGH, SCRATCH,etc) created using the Pedalboard Audio FX.

I have 2 needs:

1. When I switch from Song to Song, I want a new lighting scene in DMXIS to take effect during the entire time I have that song/patch selected and running in perform mode. Ideally, that would be on a 5 second delay, so in case I am quickly scrolling through songs looking to select one that is not ins sequence (ie the band decides to play out of order), I don't have the lighting scenes going wild.

2. THen, I want to be able to press one of my MIDI foot control buttons, and have the STROBE light fire during a lead guitar part.

To all of the kind Wizards out there, please help.

Thanks

Ryan
