Reply to Effects Mapping Help!!

HI Guys,

I am setting up an OSC template and i have a quick question regarding the effects.

I am looking to do a midi fighter style page for using effects. I can map the effects no problem but as soon as i let go of the button which triggers an effect the effect then disappears out of the slot and leaves the slot empty. Any ideas how i get round this so it either defaults the the last effect in the slot or the effect that what just triggered by OSC??

Any help or advise would be greatly received.

Cheers guys.
Tom
