User Manual

loop number is currently activated. Also you can only change
loops when the 45000 is idle, you cannot change loops while
its playing back. Here’s the procedure for changing loop num-
bers on the 45000:
1. Press and hold the STEREO MODE button. After approxi-
mately 2 seconds, all 4 track LEDs will light up.
2. While continuing to hold the STEREO MODE button, use
the OCTAVE button to increment by 1 or use the REVERSE
button to decrement by 1. You can hit either OCTAVE or
REVERSE multiple times to count to the loop you want
to activate. Holding down either button will not change
the loop number in decades as can be done on the Foot
Controller.
3. Release the STEREO MODE button to activate the new loop
number.
Since there is no loop number indication on the 45000 main
unit, you can press the PLAY button to see what’s going on with
the newly loaded loop: if the 45000 remains idle, no audio has
been recorded for this loop number, if it does playback, listen
to the loop to decide if you want to keep it or you could record
over it using the New Loop procedure described above.
Changing Loop Numbers With MIDI
An external MIDI device can be used to change the loop num-
ber with either MIDI Program Change (PC) or Control Change
(CC) messages.
MIDI Program Change:
The MIDI PC number sent to the 45000 selects the new loop
number. For example send MIDI PC #2 to the 45000 and the
45000 activates Loop 1. Send MIDI PC #100 to the 45000 and
loop number 99 is activated. Please note: most MIDI devices
send out Program Changes from 1 to 128 which in turn
selects loops 0 to 99; other devices may send 0 to 127 which
would also activate loop numbers 0 to 99.
MIDI PC #122 is Loop Down. When the 45000 receives this
message, it will decrement the loop number by 1.
MIDI PC #123 is Loop Up. Upon receiving this message, the
45000 increments the loop number by 1.
MIDI Control Change:
MIDI CC #115 selects a new loop number directly. For exam-
ple, send MIDI CC #115 with data value equal to 0 and Loop 0
will be activated. Send a data value equal to 99 and Loop 99
will be selected.
MIDI CC #113 is Loop Down and CC #114 is Loop Up. Each
of these two CC messages respectively decrements or incre-
ments the loop number by 1. The data value must be 127 in
order for the decrement/increment to be acknowledged. Any
other data value other than 127 will be ignored.
When using MIDI messages, the 45000 can change loop num-
ber in Idle or Play modes but ignores the messages when it is
in Record or Overdub modes. If it receives a new loop number
message while in Play mode, it will change over to the new
loop after the current loop has played out to its end point.
The master MIDI device must be set to the same MIDI channel
as the 45000 in order for the 45000 to acknowledge receipt
of the MIDI PC and CC messages, unless the 45000 is set to
OMNI ON mode. See the In-Depth MIDI section for more on
MIDI channels.
Erasing Audio
Once you begin recording a New Loop on any given loop num-
ber, all of the previously recorded audio for that loop number
will be overwritten and cannot be retrieved. For example if the
45000 is set to Loop 5 and Loop 5 has audio recorded onto it,
pressing NEW LOOP and then the RECORD button will erase
the audio that was on Loop 5 and record new audio. The loop
length will also be updated to the new loop length upon com-
pleting the New Loop.
