turning vst´s on and off?

[sso]

how would you do that, if possible, lets say putting a vst on a channel and then turning that vst off and on with a command?

Map a Zxx to its dry/wet ratio. This will not actually turn off the VST, but you won't hear its effects. Setting a plugin to bypass using a Zxx is not possible though.

And if you wonder how that can be done, see here: http://wiki.openmpt.org/Manual:_Macro_Configuration#Parametered_Macros
