Contrôler l'Orb avec un contrôleur midi et non ipad

Du coup je m'auto-réponds, comme ça si d'autres se posent la même question et cherchent la réponse sur AF :

The Orb's movements can be controlled using a MIDI controller.

Since the Orb's movements are plotted on 2 different X/Y-type planes, "Angle"
and "Radius," they must be assigned to different MIDI CCs to work
effectively.

To control the Orb using MIDI CCs, follow these steps:

1. Right-click on the Orb and choose "MIDI CC Learn" to MIDI Learn the Orb's
Angle (the default setting).
2. Move a physical control on the MIDI device
that is connected to Omnisphere to control the Orb's Angle.
3. Right-click
again on the Orb and choose "Switch to Radius" to MIDI Learn the Orb's
Radius.
4. Move a different physical control on the MIDI device to control
the Orb's Radius.

The Orb will be instantly paired, and can then be controlled from a MIDI
Controller. All MIDI Learn assignments are stored with the MULTI, saved with the
host project file, and can also be saved as a MIDI Learn Template.
