About the default mapping:
When you use a combo of Mackie Control and Extender, the default mapping is
very similar to that of the Mackie Control - please see that description (earlier in
this document) for details about all global mappings (transport, navigation, etc.).
The Extender adds eight more channels to the Mackie Control. This leads to the
following differences in the mapping for various Reason devices:
Mixer 14:2
All 14 channels are available at the same time - the Channel Left/Right buttons are
not used.
Line Mixer 6:2
Rotaries 1-6 control channel pan settings; rotaries 9-14 control Aux Send levels.
Subtractor
There are no variations - all settings are available at the same time.
Malström
The first eight sets of faders, rotaries and buttons always control filter settings.
Faders/rotaries/buttons 9-16 can either control settings for Oscillator
A+Modulator A or Oscillator B+Modulator B. These variations are selected by
pressing the Assignment buttons Track or Send, respectively.
NN19
A few more parameters are available in the default mapping, due to the larger
number of faders and rotaries.
Redrum
All 10 drum channels are available at the same time - the Channel Left/Right
buttons are not used.
BV-512 Vocoder
As with the Mackie Control, the faders control the band levels and you use the
Channel Left/Right buttons to select which vocoder bands to control. With the
Combo however, you can control sixteen bands at the same time.
