Logic Pro 9The DAW protocol used by Logic Pro 9 is the Mackie Control Unit (MCU) protocol. Therefore when a Logic Profile is assigned
to a Nucleus DAW layer, in order for Nucleus to control Logic, a Mackie Control together with a Mackie Control Extender must
be added to Logic Pro. Click on Preferencesthen Control Surfaces Setup to access the menu shown below.
Both the Mackie  Control and Mackie  Control Extender  provide
just eight faders. Therefore Nucleus faders 1-8 are mapped to the
Mackie Co ntrol po rts  along  with t he mas ter fa der and  DAW
Control function switches whilst faders 9-16 are  mapped to the
Mackie Control Extender ports. The actual ipMIDI ports used will
depend on which layer (or layers) have a Logic Profile assigned.
(Refer to  the  previous  page  for  a  list  of  Nucleus’  MIDI  port
assignments.)
It  is  recommended  t hat  you  delete  a ny  Mackie  controlle rs
automatically created  on set-up,  and recreate the m manually.
Note that  if  the physical  arrangement  is  reversed, then  the
Nucleus faders will not map correctly to the on-screen faders in
Logic.
If Logic is the only DAW connected to Nucleus, then provided that
there is only one DAW Layer set  up with an MCU based  Profile,
Logic should  automatically  detect  the  two vir tual cont rollers
which will be shown in  the Logic Control Surfaces  Setup menu
(as shown above),  with the  appropriate N ucleus ipMID I ports
assigned. If Logic fails to detect  the control surfaces, then the
controllers can be added manually via the New, Installmenu and
the appropriate MIDI  Out port and  Input assigned.  Full details
can be found in  the online Logic  Pro Control Surfaces  Support
Guide in the Logic Helpmenu.
If Nucleus is set up with multiple MCU profiles in the DAW layers, then the automatic detection option must be disabled and
the controllers added and configured manually. Check the Disable Handshakebox in the DAWtab in Nucleus Remote (located
below the Edit Profiles button) for all the DAW layers assigned to a MCU Profile prior to  starting the Logic application. This
will prevent Logic automatically detecting multiple Mackie Control Units. 
For other DAWs, please refer to the relevant User Guide for details about configuring MIDI controllers.
See Section 5for a description of the Remote’s DAW tab.
