The Effects

Looper (Ultra Only)
The Looper is a sixteen second phrase sampler. The Looper controls are different than the other
effects in that they are “pushbutton” controls rather than knobs. Selecting the control and pressing
ENTER toggles the state of the control. The Looper controls have dedicated MIDI CC assignments
as well so you can control the Looper using a MIDI footpedal or other MIDI device. Access to the
CC assignments is done in the I/O menu.
RECORD - When record is activated the Looper records the audio input. Pressing record again
stops recording and immediately begins playback.
PLAY - Toggles the playback state. If recording, pressing play immediately stops recording and
starts playback.
ONCE - This control plays the phrase one time only and then stops. If the phrase is already playing
the phrase continues playing until the end and stops. If the playback is stopped, pressing this plays
the phrase one time. Pressing this again while the phrase is playing resets playback to the beginning
allowing for “stutter” effects.
STACK - Pressing this adds the audio input to the existing phrase. Pressing it again stops the
addition. The existing audio is faded every time through the loop.
REV - Pressing this reverses the direction of the loop playback.
Multi Delay
The Multi-Delay in the Axe-Fx is a rhythmic delay block with five sub-algorithms: Quadtap delay,
Plex Delay, Plex Detune, Plex Shift and Band Delay. The Axe-Fx Ultra contains four additional
sub-algorithms: Quad-Series, Ten-Tap, Rhythm Tap and Diffusor. Delay times can be controlled
by tempo allowing for rhythmic patterns to be easily created. All delay lines can be modulated by
up to four LFO’s.
The following diagrams illustrate the various algorithms. Parameters vary by type but are listed
together for ease of reference.
