Open Global Menu, scroll down to CV Config.
This is where you configure the 4 outputs.
Then use CV Track for sequencing.
The 4 Global Slots offer four different configurations.
If it says Global Slot 1, you are on Slot 1 and all your stuff like set midi channels etc. are stored on this Slot.
Change to Slot 2 with arrow keys and you can set different midi channels or IIRC anything else in the Global Menu.
What cv do you want to send? Clock, pitch cv, gate, trigger?
