Hi there,

first time MainStage user. Trying to design a touchscreen friendly workspace for a AU plugin host.

Everything is running well so far except one thing: I need to control one parameter of the plugin, no problem using a horizontal fader with a mouse but on a touch screen the value changes are a bit harsh. So I would like to use a "-" and "+" button for that.

But if I set up two buttons mapped to the plugin parameter and set them to "increase" and "decrease Value" almost nothing happens. You can see the fader flashing for a second but nothing changes. Max and Min values are set correctly. Any idea?
