Hi - Today I set up my new UR44 Audio Interface but am not able to activate the above app. Each time I try to click on it in my applications folder, up comes the message “no device found”. Can anybody tell me how to make this work ?

Hi crocus,

dspMixFX requires a supported class compliant device properly connected to the iPad.
If this is the case, did you activate the CC mode for the device in use?
