>>> Hmmm, I did just think of something, though. For undo or touch automation, you want to capture the state of the parameter(s) in the gesture before any changes occur, so in other words, when you get the gesture-start event. For that reason, it would be good to know which specific parameter(s) will be changed. <<< In DirectX 8, the capture and release methods take an array of parameters, actually. The parameters you capture are supposed to balanced with the ones you release, though the spec doesn't enforce that. ---------------------------------------------------------------------- Generalized Music Plugin Interface (GMPI) public discussion list Participation in this list is contingent upon your abiding by the following rules: Please stay on topic.
