LEVEL KNOB

Controls the output level of the loop being played.

TEMPO KNOB

Controls a loop’s playback and overdub speed.

OVERDUB KNOB

This knob acts like a feedback control for the looper during overdubs.

MODE KNOB AND BUTTON

The MODE knob has two functions: 1) cycling through the available modes and 2) adjusting the value of the selected mode. All modes and values are shown on the 4-digit display. The MODE knob has no pointer because it can be continuously rotated in either direction and can also be pushed like a button.

REVERSE BUTTON

Press the REVERSE button to play the loop in reverse. The REVERSE button glows green when enabled. Reverse can be initiated at any time: during playback, overdub or even before recording a new loop. If REVERSE is enabled upon ending a new loop recording, the loop will immediately playback or overdub in reverse.

OCTAVE BUTTON

Pressing the OCTAVE button causes the speed of the loop to drop by half so that the pitch of the loop goes down one octave and the tempo is halved. If a loop is overdubbed during half-speed mode, returning to normal speed playback causes the pitch of the overdub to go up one octave and the tempo is doubled. The OCTAVE button glows green when enabled. OCTAVE can be used at any time during playback or while overdubbing a loop. If OCTAVE is enabled prior to new loop recording, the loop will immediately playback or overdub at half-speed.

1 SHOT BUTTON

Pressing the 1 SHOT button enables or disables 1 SHOT mode. When 1 SHOT is enabled and its button is lit, the loop plays back once and then stops. You may overdub in 1 SHOT mode as well.

EXT CLK BUTTON

When this button is lit, the 1440 will operate at a tempo set by external MIDI clock. The number of beats per bar are set in EXTC Mode.

This button is also used to set up Expression Settings.

MOMENT BUTTON

While in Delay or Delay+Looper modes, enabling MOMENT changes the function of the BYPASS/STOP footswitch to only allow the delay effects while the footswitch is pressed down. The delay effects are bypassed when the footswitch is released. When MOMENT is disabled, the BYPASS/STOP footswitch works like a normal latching footswitch, toggling between bypass and effect modes with each press and release of the footswitch.”

TAILS BUTTON
