Hi,
I had a look, but I could not find any feedback for the Globals. So I don't think it is implemented. I can add it to the wishlist.
Same goes for tempo tap feedback.
Regarding your last question, you could try to invert the midi task in the midimap. So originally it would be something like this:
In <actionlist label="feedback" source="System">:
<action>
<trigger type="Unsigned" specifier="Change">Grand Master</trigger>
<tasks>
<task type="Midi" function ="Control">
<argument type="Midi Address">Channel 0 - Message 11 - Index 9</argument>
</task>
</tasks>
</action>
You can change the Control to Inverted Control like this:
<action>
<trigger type="Unsigned" specifier="Change">Grand Master</trigger>
<tasks>
<task type="Midi" function ="Inverted Control">
<argument type="Midi Address">Channel 0 - Message 11 - Index 9</argument>
</task>
</tasks>
</action>
I haven't tested it yet, but it could work.
Greetings,
Bootsy
