I started to integrate a Numa Organ 2 to my GP rig. The drawbars of the Numa Organ 2 are coded such that drawbar index 0 is MIDI 0 and drawbar index 8 is MIDI 127. It seems that this is inversed with regard to the GP widget drawbars. So using MIDI sync works in both direction, but the sense of the drawbars is inverted. I thought, easy, I simply have to set the “invert” option in the MIDI settings of the widget drawbars and that’s it. But, unfortunately, it seems that it doesn’t invert the value that is sent back to the Numa Organ 2 (or something like that), such that moving a drawbars generates a perpetual motion of the drawbars.
Am I supposed to use scripting to solve this issue ?
Furthermore, when investigating the origin of the issue, I monitored the MIDI message received from the Numa Organ 2 (see picture below) using a MIDI monitor plugin connected to the Numa Organ 2 MIDI in block. From there, I can see the Note messages, but not the CC of the drawbars, while it is visible in the general MIDI monitor.
Is there a clear explanation to this ?
