How can I change the Channel Strip setting when I change patches?

Hi there guys,

I have recently put together a live set for a client of mine, using MS as a playback engine for backing tracks but also as a live looper.

The artist in question in a Didgeridoo player and I need to have different channel EFX for each track.

I have set up a single concert and have multiple patches acting as different songs, so that he can click through his set list.

It all works pretty well apart from the fact that that I want to change the EFX on his main input track, as he clicks through each patch.

I can't for the life of me, work out how to do this,

Here's a pic of how I have ot set up.

If any one can shed some light on this I;d greatly appreciate it.

All the best
