A way for automatically morphing tracks?

What exactly do you mean by Morphing (crossover of the audio and/or of certain plugin parameters ? ) Wow is it supposed to happen ? (programmed for playback or something (like a knob or a Midi CC message) usable in a live situation ? ) For playback I suppose that envelopes are great for morphing anything. -Michael

Hi, Thanks or reply. Yes, a crossover for tracks. Here's the scenario: several tracks with same motive, but different instruments, playing simultaneously, but only one track is hearable at a time, and it needs to change very fast. I could do that manually, but it would take a very long time.

I still don't get what kind of workflow you have in mind. -Michael
