12 Nektar Impact LX49, LX61 & LX88 User Guide www.nektartech.com
Keyboard, Octave and Transpose
The Impact LX keyboard is velocity sensitive so you can play the instrument expressively. There are 5 different velocity
curves to choose from, each with varying dynamics. In addition, there are 3 fixed velocity settings.
We recommend you spend a little time playing with the default velocity curve and then determine if you need more or less
sensitivity. You can learn more about velocity curves and how to select them on page 24.
Octave Shift (not applicable to LX88)
To the left of the keyboard you find the Octave and Transpose shift buttons.
With each press the left Octave button will shift the keyboard down one
octave.
The right Octave button will similarly shift the keyboard up 1 octave at a time,
when pressed.
The maximum you can shift the LX keyboard is 3 octaves down and 4 octaves up
and the LX61 can be shifted 3 octaves up. This covers the entire MIDI keyboard
range of 127 notes.
Program, MIDI Channel and Preset Control with
the Octave Buttons (not applicable to LX88)
The Octave buttons can also be used to send out MIDI program messages, change
the Global MIDI channel or select the Impact LX’s control presets. To change the
buttons function:
Press the two Octave buttons simultaneously.
The display will now show the current assignment abbreviation for a little over 1 second.
Press the Octave up or down button to step through the options.
Below is the list of the functions that the Octave buttons can be assigned to control. The Display column shows the text
abbreviation for each function as they appear on the Impact LX display. The function remains assigned to the buttons until
another function is selected. After power cycling the default function is selected.
