As far as I can tell two plugins will work fine but if I have a slider
sending messages on a channel called "freq" it seems to send messages
to each plugin with a channel called "freq". This could well explain
why using pvsblur and SpSbSynth work at the same time, they are not
sending message on the same channel. I need to do some quick tests. I
wonder if I change the channel name in the pvsblur example to match
that of the SpSBSynth examples what behaviour will I get...

Rory.
