I have not used PD for a couple of years so I'm pretty much having to learn it all again.

I'm sure this is a basic question but I am trying to make a patch where live audio manipulates video in Gem. I have got as far as trying out some of the different [pix_...] objects but it appears that Gem can only support two connected FX at a time. I have it up so when one is selected, any others are switched off using 1 and 0 messages but whenever I connect more that one, there is always one that is cancelled out.

Is there a way around this or is it just the way it is?

Any Help would be appreciated.
