6 Nektar Impact LX49+ & LX61+ User Guide www.nektartech.com
The Impact LX+ keyboard is velocity sensitive so you can play the instrument expressively. There are 4 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 18
Octave Shift
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 LX+61 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
The Octave buttons can also be used to send out MIDI program messages, change the Global MIDI channel or select the Impact LX+’s cont-
rol 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.
