It takes a bit more configuring, but you can get that on the newer firmware too:
- Use Ramp 9H to turn off every channel mode except the tint-ramping mode. Afterward, 3C switches between smooth and stepped ramping.
- Use Off 9H to enable stepped tint ramping. This makes 3H switch immediately from one channel to the other, instead of ramping between.
Basically, the old 3H “tint toggle” is still available in newer versions. It’s just buried a bit.
