Tempo
Rate
Source
The parameters in the Tempo menu: Rate, Source, Beat Value, Tap Average,
Tap Source and Source Level, allow you to select the way in which the actual
tempo in BPM is determined for each effect.
The MPX G2 gives you unique control over tempo. In the MPX G2, any delay
parameter and any time-based modulator (LFO, etc.) can be individually
assigned to an absolute time value, or assigned to a tempo value.
For example, a delay time can be set to a specific number of milliseconds, and
you will always get a delay of that number of milliseconds, regardless of tempo
changes. Alternatively, a delay time can be set to a specific ratio of echoes to
beats. Now, if you create a rhythmic echo pattern, delay times will be linked to
tempo. When you change tempo, the delay time will change to maintain the same
rhythm at the new tempo.
With the LFOs, the rate of change can be an absolute value (such as once per
second), or it can be linked to tempo (for example, once every four beats). Any
delay parameter or LFO rate can be set to its own individual rhythm, allowing you
to set up an effect which will change in a rhythmically interesting way — evolving
over time, for example, as opposed to being a mere series of repetitions. Once
delays and LFO rates are assigned, tempo rate can be easily changed in a variety
of useful ways.
Tempo Rate can be set internally or via MIDI Clock. If Tempo Source is set to
Internal, you can dial in any tempo from 41-400 BPM, or you can press the front
panel Tap button twice in rhythm to establish the rate you want (allowing you to
change tempo on the fly from any mode). You can also have the value of a patch
source act as a tap trigger (See Chapter 4: Patching.) or choose to have your
tempo transmitted as a MIDI Clock signal to control the tempo of connected MIDI
devices. (See Chapter 5: System Controls or Chapter 6: MIDI Operation.) If
Source is set to MIDI Clock, MPX G2 tempo will sync to incoming MIDI Clock.
Whether tempo is set internally or via MIDI, the front panel Tempo LED will flash
at the current rate whenever any delay or LFO rate is set for tempo control.
MPX G2 programs can have their own tempo rate settings which are stored with
the program. You can override these individual tempo rates with a global tempo
rate in the System Setup menu. Tempo is also available as an independent patch
source which can control any program parameter. (See Chapter 4: Patching and
Chapter 5: System Controls.)
This is the current tempo (in beats per minute). When Source is set to Internal,
you can select any rate here from 41 to 400 BPM. The Tempo LED will flash at
the new rate. Fractional tempos can be tapped in, but the display will always
show the nearest whole number value.
You can choose to have tempo determined by the MPX G2 Tap and Rate
controls (Internal), or by MIDI Clock (MIDI). Tap also acts as a reset, setting the
downbeat of the LFOs.
