So to use the HUI protocol you need to be able to program your keyboard to spit back the response every time it receives the keepalive message from ProTools. If it does not get the proper response back then ProTools assumes the HUI has gone away and disables it. ProTools will periodically send a message to the HUI and expect the proper reply. The Mackie HUI has the limitation that there are periodic status checks.
In your case your keyboard isn't likely to have motorized faders so this is probably the desired behavior. It does not support motorized faders so if a fader changes from ProTools then you will have to move the fader through the current point before ProTools will respond again. IIRC it uses a predefined mapping between CC numbers and faders. But it is on purpose so Digidesign can sell control surfaces.ĭo some searching and reading on the CS-10 protocol. So perhaps it is not a 'flaw' but certainly is a major LIMITATION in ProTools. This limitation is on purpose so that Digidesign can sell control surfaces. The documented protocols are for the JL-Cooper CS-10 and the Mackie HUI. The control surface features 25 velocity-sensitive tri-color LED back-lit trigger pads with aftertouch for sequencing melodies and.
It only supports its own (undocumented) control surface protocols, and two documented legacy control protocols. Hiding on a grassy knoll we have a USED Samson Conspiracy MIDI Control Surface Designed for electronic producers and performers the Samson Conspiracy MIDI Control Surface is a portable USB bus powered device that allows you to command your software with authority. ProTools does not support arbitrary MIDI control of parameters.
