with this one you could use the PWM to balance your colors and then use the analog to do your sunrise sunset

The problem with that is that you can only choose 1 of those options.
If you have a Reef Angel or similar controller you can use PWM, but if your just starting out and have nothing you cans use some simple pots to control the channels. For those that want something more different, the Arduino route can be used with I2S and a program can be written for control.

Also I noticed something weird this morning...
There's only 4 hard wired dim controls. Seems like Channels 1 and 2 share the same dimmer as well as 3 and 4 share another. channels 5 and 6 are individually controlled.

I sent TI an email to clarify this for me as if this is only a PWM or Analog control only or does it apply to serial control as well.
Keeping fingers crossed either way as sometimes its just a matter of not having enough pins on the device.
