CONTROLS and INDICATORS
–
LEVEL Knob – Controls the output level of the Loop being played. Your dry
signal remains at unity signal level from input to output. The dry signal also
remains analog throughout the 720.
LOOP Footswitch – Use the LOOP footswitch to record, overdub, and playback
loops. The LOOP footswitch can also be used to stop and undo-redo loops. See
the QUICK START GUIDE on page 5 to learn how to use this footswitch to
create loops.
STOP/FX Footswitch – The STOP/FX footswitch can be set to either STOP
mode or FX mode. Select either mode by pressing and holding the PUSH:
MODE button for 2-seconds. When in STOP mode, a DOT appears on the
display next to the STOP label. When in FX mode, the DOT is off.
REC LED – Indicates when a loop is being recorded or overdubbed.
PLAY LED – Indicates when a loop is being played or overdubbed.
MEM LED – Indicates loop audio is in memory for the current loop bank.
LOOP Knob and PUSH: MODE Button – The LOOP knob has no pointer
because it is attached to a rotary encoder that can be continuously rotated in
either direction. This knob also has a PUSH: MODE button with two functions: 1)
to cycle through one of three available modes, and 2) once a mode is selected,
to adjust the value of that mode from 0-9. All modes and values are shown on
the digit display.
SELECTING/ ADJUSTING MODES – The 3 selectable modes are toggled on and
off by pressing the MODE button once. When mode-select is active, the digit
display will flash the currently selected mode. Turn the LOOP knob to cycle
through the three possible modes:
L = Loop Select
p = Loop Progress
F = Fadeout Time
When you arrive at the mode you would like to adjust, press the MODE button
once to select the mode. The display will stop flashing and it will show the
selected mode value from 0-9. The selected mode can now be adjusted with the
LOOP knob from 0-9.
