[maxmsp] 2 Channel Crossfade for Audio and Video

Greetings,

I am working on a patch that allows me to crossfade between 2 videos (A and B). I understand the crossfading of video but I am having a tough time crossfading the audio that accompanies the quicktime video. I know I am almost there with the idea but I just can't grasp the concept of crossfading using spigot~. The patch is posted below. Thanks folks.

-Jim
