45000 as MIDI Clock Slave and Master
When the 45000 creates a loop as a MIDI Clock slave, it
needs to work in Quantize mode in order to create loop
lengths that are exactly x number of bars in length. If you do
not use the Quantize feature, the loop’s length will be com-
pletely variable depending on when you started and stopped
the recording of a new loop and most likely will not sync up
with the MIDI Clock master, even though the 45000’s tempo
is in sync with the master.
1. If you are using the 45000 as a MIDI slave and want to pro-
duce loops of a set number of bars, the best way to do this
is to record your initial loop (or New Loop) with Quantize
set to ON. Follow this procedure:
a. Press the EXT. CLOCK button so that its LED is lit solid
or blinking. You are now in Ext. Clock mode.
b. Press the QUANTIZE button so that its associated LED
is lit. You are now in Quantize mode
c. Press the NEW LOOP button. The Record LED should
blink steadily.
d. Press the RECORD button, now the Record LED should
be blinking rapidly. This means that the 45000 is wait-
ing for a MIDI Clock signal and a start command from
the MIDI master. Once received it will immediately
begin recording.
e. Press play on the MIDI clock master, the 45000 will
immediately begin recording.
f. In Clock-Only mode, the MIDI master could be playing
back during the time you press NEW LOOP. At the time
you press RECORD, it will begin recording on the next
BEAT 1 that it receives from the MIDI master.
g. In Quantize mode the 45000 will create loop lengths to
the nearest bar. Each bar is 4 beats in length. So if you
make a loop that is two bars long, it will have 8 beats.
As an example, lets create a 4 bar loop. Begin record-
ing a New Loop with Quantize set to ON as described in
other sections of this manual. While recording, press
the PLAY button to set the loop length, either after the
3rd beat in the 4th bar or before the 3rd beat of the 5th
bar. The 45000 will either extend or truncate the loop
length to be exactly 4 bars. At the end of the 4th bar,
the 45000 will stop recording and immediately begin
playing/overdubbing the loop you just recorded. If you
want to just play the loop back and not overdub press
the NEW LOOP button to end the loop. If you want to
simply end the loop and not playback at all, press the
RECORD button to end the loop.
2. While in Quantize mode, if the MIDI Clock master is
already playing when you hit the NEW LOOP button, then
the 45000 will either begin recording as soon as you hit
its RECORD button or it will first give a one bar count-in
and then begin recording. To skip the one bar count-in
and start recording immediately, make sure to press the
RECORD button on the MIDI clock master’s beat 1. If you
want the 4 beat count-in, press the RECORD button at any
point in the bar after beat 1.
3. If the loop length, in bars, is known prior to recording the
loops, you can create a blank loop before you start playing.
For example if you create a 2 bar loop with Quantize On,
then that loop will always be exactly 2 bars no matter the
tempo the 45000 is receiving or sending. You can create
the 2 bar loop without any MIDI being sent to the 45000,
then later, turn on Ext. Clock on the 45000 and give it MIDI
Clock. The 45000 will record/play at the master’s tempo
and the loop will always be 2 bars. You could even make
multiple loops on the SD card with different loops lengths,
Loop 0 could be a 2 bar loop, Loop 1 a 4 bar loop, etc. If
you don’t want or need the audio that recorded the last
time you started with a blank loop, just overdub over the
loop with Punch-In set to on.
4. When you are not using Quantize mode, the following is
true about the 45000:
a. The tempo sent out of the 45000’s MIDI Clock has
nothing to do with the loop length; it only has to do
with the current setting of the TEMPO Slider.
b. When creating loops with the 45000, while the 45000
is a MIDI Clock slave, if the loops are created with
Quantize off, there is no guarantee that the loops will
be exactly x number of beats or bars in length unless
the master MIDI Clock device can send out Start and
Stop commands for the 45000 to begin and end
recording and even then they may not be exact. It is
best to always record with Quantize set to On when
using the 45000 with MIDI Clock.
