Hello,
There are currently no plans for UltraChannel updates.
As far as using UltraChannel with SplitEQ, I can’t say there is a “best” way to use it since it depends on what you are trying to achieve and how you use it. I would suggest experimenting with how you are routing the 2 plug-ins together. You may find that using SplitEQ before UltraChannel will help tame a signal before applying gate/compression, or you can try using SplitEQ after UltraChannel to fine-tune your EQ or add some sheen or width.
