ctl button on my GT-6

hi everyone,
i'm trying to program my gt6 so that when i'm on a "regular" patch,like bank 1 patch 1 i have a sound for backing guitar and when I push the ctl button I get a solo sound (in order to save some space).
now , for my solo sound I need my backing sound plus some chorus and delay and a wah effect.
I have tried to assign these effects to my control button but it seems that it will take just one effect instead of 2 or 3.

anyone got experience with this?

I have the older GT-3 , but I think they should be similar in basics.

Make sure that in each assign , you have the source set to ctl pedal , and they all have the same operating mode (normal or toggle) , and the max and min values are setup correctly.
