4. BPM system
In the ZERO4, the BPM (Beats Per Minute) setting is used as the master
clock for MIDI and for effects that are synchronized to the BPM. The
ZERO4 has an Auto BPM function that automatically detects the BPM from
an audio input source. You can also set the BPM manually.
Setting the BPM manually
Turn the TIME/AUTO push knob to specify the desired BPM.
Setting the BPM using tap tempo
Press the TAP button at least three times to the beat of the song. The inter-
val at which you pressed the button will be calculated, and specified as the
BPM value.
Setting the BPM automatically
Here’s how you can use the Auto BPM Counter to detect the BPM of a song
that’s being input
1. Press the BPM CH SELECT button to select the source
whose BPM you want to detect.
2. Press the TIME/AUTO push knob to turn AUTO BPM
on; the BPM will be detected automatically.
If the BPM was detected incorrectly, leave AUTO BPM turned on, and
press the TAP key at the beat of the song; the BPM will be automati-
cally detected using your beat as a guide. If AUTO BPM is on, changes
in the BPM of the audio input are detected automatically, and the BPM
is adjusted accordingly.
TIP:
The BPM cannot be detected correctly for songs that don’t
have a definite beat.
5. Channel effects
The channel effects are inserted into each mixer channel.
You can choose from eight different effect types, and operate the TIME,
MOD, FB, and FX MIX knobs to control the sound.
TIME
knob
Adjusts a time- or speed-related parameter.
MOD
knob
Adjust a parameter that applies modulation to the
sound.
FB
knob
Adjusts a feedback-related parameter.
FX MIX
knob
Adjusts the DRY/WET amount of the effect (common
to all types).
Effect type list
LFO LPF
A low pass filter whose cutoff frequency is
varied by an LFO.
TIME
: Adjusts the LFO speed.
MOD
: Adjusts the depth of LFO modulation.
FB
: Adjusts the amount of resonance.
LFO HPF
A high pass filter whose cutoff frequency
is varied by an LFO.
TIME
: Adjusts the LFO speed.
MOD
: Adjusts the depth of LFO modulation.
FB
: Adjusts the amount of resonance.
PHASER
An effect that creates modulation by using
an LFO to shift the phase of the sound.
TIME
: Adjusts the LFO speed.
MOD
: Adjusts the depth of LFO modulation.
FB
: Adjusts the amount of resonance.
FLANGER
An effect that creates intense modulation
and a sense of pitch movement. It is effec-
tive when applied to a sound that contains
numerous overtones.
TIME
: Adjusts the LFO speed.
MOD
: Adjusts the depth of LFO modulation.
FB
: Adjusts the amount of feedback.
SLICER
Cuts the sound in synchronization with
the BPM.
TIME
: Adjusts the interval at which the sound is
cut.
MOD
: Adjusts the proportion for which sound
