I try to implement my own software controller fro Pro Tools using PureData.

My questions are:

Has someone used PureData to send and receive Mackie HUI Protocol messages to/from ProTools?

Do you know if I can use MIDI to control ProTools from PureData?

Can I receive Midi messages from ProTools in order to know fader position, for example?

All kind of help will be very usefull for me. Thank a lot in advance.
