Ok. I used the Editor version 2.0.
To my surprise I was indeed using an older version. I didn't realize there was a new version, I'm sorry.
I just installed 2.1, updated the firmware with that editor, loaded the same presets, and there is a big improvement now.
The range now goes until 120 ! That's much better than 60
120 is workable.
However there's still a strange issue, besides that it doesn't go up to 127, also this happens:
In Standalone, when the pedal is completely up, it keeps fluctuating between 118-119 (seen in Midi Monitor app). So my volume is ableton is quickly changing/fluctuating by itself.
In Hosted mode, when pedal is up, it does stay completely still at 119. Though, it doesn't go to 127.
In any case, I think could play my gig with this, but if I can reach the 127 without strange fluctuations in Standalone, that would be perfect!
