We released a maintenance release of Gig Performer today. There is only once change that we introduced in this release
ENHANCEMENT
The MIDI Filter plugin now supports individual NoteOn and NoteOff blocking (as well as the original Note blocking). This feature makes it easy to use multiple plugins with the same MIDI source in a single rackspace and switch them on or off by simply blocking NoteOn events while allowing NoteOff events to go through.
