Assignable controls:
1
8 x rotary encoders. These are ‘360°’ controls with no end stops, and are used to control
plug-in parameters. These controls have speed-dependent resolution, so turning the encoder
slowly gives ner resolution than turning it quickly.
2
9 x 45 mm faders (slider controls), used to control volumes in your DAW mixer.
1
3
9 x press-buttons.
2
4
8 x pressure-sensitive drum pads. These can be used to trigger sounds (i.e., drums) in your
music software, and also to control Impulse’s “Arp”, “Roll” and “Clip Launch” functions
5
Mod (Modulation) wheel.
1
Impulse 49 and 61 only. Impulse 25 has one assignable fader.

Non-assignable controls:
6
Multifunction LCD display. Shows information contextually – i.e., will give you the most useful
data depending on which controls you’re currently using.
7
+ / – buttons. These are used in conjunction with the various menus, to scroll through
available options, etc. Precise function varies with menu. Pressing these buttons together
enables Help mode.
8
Template Edit buttons. A set of four buttons (Keyboard, Controls, Zones, and MIDI Chan),
which select the different menus used when modifying templates. A fth button, Setup, permits
global settings, and a sixth, Shift, enables secondary functions for some of the other buttons.
9
Octave > / Octave < buttons – shift the notes played from the keyboard ‘up’ or ‘down’ in
octave steps. Pressing the two buttons together lets you transpose the keyboard in semitone
increments. The number of octaves over which the keyboard can be shifted varies with Impulse
model; the smaller models have a greater shift range.
10
MIDI/Mixer button (Impulse 25 only) – sets Impulse 25’s single fader to be either a control
for a DAW mixer level, or an additional assignable MIDI control.
11
Plug-in/MIDI buttons – these determine whether the eight rotary encoders vary specic plug-in
parameters, mixer controls, or act as general purpose MIDI controllers. Pressing Plug-in or MIDI
while holding down Shift will step between pages in the Automap Mapping Edit window. Pressing
both simultaneously will map the encoders to the Automap mixer.
12
Mixer/MIDI buttons (Impulse 49 and 61 only) – these determine whether the nine faders
act as volume controls for individual tracks within a DAW mixer, or as general purpose MIDI
controllers. Pressing Mixer or MIDI while holding down Shift will scroll the set of DAW mixer
faders being controlled through eight channels at a time.
