Any advice on how to disable the sustain pedal on a certain rack in a certain subsession? Of course I can disable the sustain with a MIDI filter, but how can I turn the filter on/off without going into the MIDI filters dialogue? Or get the filter to turn on and off with the loading of a subsession? I've looked at triggers, at routing the MIDI input through the MIDI routing table and then adding a filter, and various other things but I could use some advice. Anyone?

The MIDI Routing Table allows filters to be applied on a per subsession basis so that's the place to do it.

OK, I'll have to try that again. . . and now I realize exactly what I did wrong. I was trying to activate/deactivate the filter within the route, instead of activating/deactivating the route itself. Learning can be painful. Many thanks.
