Fix Midi Controller Value in Mainstage

Hello all,

I want to send a controller value with a fixed value to an external device with Mainstage via button.

E.g. Button Press=Controller 30 Value 55

It works so far, but it always sends the value 127.

Can I set this somewhere?

Same problem with controllers:

I want to send only the values 1-11 instead of 1-127 for a controller e.g. B on controller 31.

is this possible at all?

Thanks !
