I made two midi tracks and assigned 1st to A and 2nd to B. I then droppped a MAX API CTL LFO into master track and had it map to master track track's mixer crossfade. I see the crossfade happen in real time, but I do not hear the resut of the cross fade. When I move the crossfade with mouse or a midi controller I hear it. Not sure why I don't hear the crossfade under the influence of the MAX API CTL LFO. Any ideas?
