Ok, then somethings wrong. Here is a description of midi clone
Create new project.
Add dial, midi channel, default values.
Change value of midi channel for newly created dial (from 1 to 2)
Edit the first dial to view the value.
The first dial has changed its midi channel to value 2 aswell.
Now remaining on the first dial click on Channel,
Click + channel
(UI drops back to playing surface)
Edit the dial to view the value.
The midi channel has incremented by 1! (Repeating above increments it again)
