El servicio de soporte de Allen&heath ha sido tan amable de responderme rápidamente a mi problema. Comparto con este foro por si sirve de ayuda a alguien más:
For Sonar,
1. Make sure the DAW control app is set to HUI
2. In Sonar make sure the DAW MIDI and Qu MIDI ports are enabled in MIDI Devices.
3. In Control Surface setup add 2,3 or 4 CM Labs MotorMix controllers required to control the Qu mixer and assign the respective DAW MIDI ports.
4. In Control Surface setup add an MMC controller and assign to the Qu MIDI ports for transport control
5. In the main window drag the coloured controller strips under the channels to the correct positions
This will give you control of faders, mutes, solo’s and transport.
NB: The Sel keys will not select a channel and Transport does not have pause and bank up/down.
Espero que os sirva!!
