4 Using Nektar Impact LX+ with Reaper www.nektartech.com
Reaper Mixer Control
To control the Reaper mixer, press the [Mixer] button to select the mixer preset. The button’s LED is illuminated while the
preset is selected and the Reaper mixer is being controlled.
Open/Close the Reaper Mixer Window
If the Reaper mixer is not in view pressing [Shift]+[Mixer] will bring it in to view. Press the same button again to close the
mixer window. While the Mixer preset is selected, your Impact LX40+ continues to control the Reaper mixer, even if the
mixer window is closed.
Channel Volume & Pan
With the mixer preset active, moving faders 1-8 will control the first 8 mixer channels in the Reaper mixer. The 8 pots control
pan for each or the corresponding channels.
LX25+: On the Impact LX25+, the 8 pots control 8 mixer channels by default. You can switch them to control Pan by pressing
and holding [Mixer] while moving the pots.
Fader 9 (on LX25+, the single fader) controls the channel corresponding to the currently selected track. As you change
tracks, you can therefore quickly change volume for the track you are working with. If you have 16 tracks in your song and
the currently selected track is 12, that would result in faders 1-8 controlling mixer channel volume 9-16 and fader 9
controlling channel volume 12.
Mute & Solo
Fader buttons 1-8 control mute for each of the tracks the faders are assigned to control. If you prefer to solo tracks, you can
press and hold fader button 9 while pressing fader buttons 1-8. The 8 buttons will now control solo for their corresponding
tracks.
LX25+: On Impact LX25+, you can use the pads to control mute for tracks 1-8. Press and hold [Mixer] while hitting pads 1-8.
This will toggle mute on or off for the corresponding channels. Release the [Mixer] button and the pads revert to trigger MIDI
notes. It is not possible to control the Solo function with LX25+.
Bank Over (1-8), (9-16) etc
If your song contains more than 8 mixer channels you can bank over so the faders 1-8 control the next group of 8 channels.
To do this, press [Shift]+[Bank>] (the second fader button). The faders, pots and fader buttons are now assigned to control
channels 9-16. Push the same key combination again to control 17-24 etc.
To go back you press [Shift]+[<Bank]
LX25+: On Impact LX25+ press and hold [Mixer] while pressing [Octave-] or [Octave+] to move the bank down or up.
Master Volume
You can control the Master Volume fader of the Reaper mixer by pressing [Fader button 9] and then move fader 9 while the
button is pressed.
Upon release of the button, fader 9 will revert to control the current channel volume.
LX25+: On Impact LX25+, press [Mixer] and move the [Fader] to control master volume.
