I don't know of any standard. I have a MOTU Mixer7s. It uses continuous
controller messages to control volume, pan, treble, bass, efx1, and efx2.
They simply assigned CC's sequentially. This way you can get everything
on a single channel. They also implemented "smoothing." You can send
a CC value to set the amount of global smoothing, and each channel can have
smoothing turned on or off. They use this to avoid zipper with only
128 values.

BTW. I've always considered this unit an excellent purchase. Eight
stereo channels, all MIDI automated, in a single rack space, for ~$300. 
Too bad they don't make them anymore.
