Dynamic modulation (Dmod)
and Tempo Synchronization
Dynamic modulation (Dmod)
Dynamic modulation lets you control certain effects
parameters in real-time, using either the built-in controllers
or MIDI. These effect parameters are marked with the logo
.
For more information, please see “Dynamic Modulation
Sources (Dmod)” on page 380.
Tempo Synchronization
You can synchronize some effects parameters, such as LFO
speeds and delay times, to the system tempo. This lets you
sync the effects to Program LFOs, Drum Track, Arpeggiator,
the internal sequencer, or an external MIDI clock.
These effects parameters are marked with the logo .
Synchronizing LFOs
Most effects with LFOs, such as 010: Stereo Wah/Auto Wah,
can be synchronized to tempo. This applies to the individual
effects LFOs, and also the Common FX LFO.
To set up LFOs to synchronize to tempo:
1. Set MIDI Sync to On.
2. Set the BPM as desired.
To synchronize to the system clock, set BPM to MIDI.
To set the LFO to a specific tempo, separate from the system
clock, set
BPM to the desired tempo (between 40.00 and
300.00 BPM).
3. Use the Base Note and Times (x) parameters to set the
rhythmic value of the LFO.
For instance, if you set Base Note to 1/8 and Times (x) to 2,
each cycle of the LFO will last for a quarter-note (two
eighth-notes).
Synchronizing Delay Times
Delays with “BPM” in their title will sync to tempo.
For instance, you might set up effect 065: Stereo BPM Delay
as follows:
1. Set L Delay Base Note to 1/8, and Times (x) to 1
2. Set R Delay Base Note to 1/16, and Times (x) to 3
This means that the left channel will be delayed by an
eighth-note, and the right channel will be delayed by a
dotted eighth-note (three sixteenth-notes).
3. Set the BPM as desired.
To synchronize to the system clock, set BPM to MIDI.
To set the delays to a specific tempo, separate from the
system clock, set
BPM
to the desired tempo (between 40.00
and 300.00 BPM).
If the combination of the tempo, Base Note , and Times (x)
settings in conjunction would exceed the maximum delay
time, a warning such as “Time Over? >OVER!” will appear
in the display. If this happens, just reduce the delay time.
Note that the maximum delay time depends on which delay
effect you’re using. For instance, the maximum delay time
for 065: Stereo BPM Delay is 1,360msec, while the maximum
delay time for 169: ST. BPM Long Dly is 2,730msec.
Dynamic modulation to control an effect parame-
ter in realtime
As an example, let’s set up dynamic modulation to control
an effect parameter in realtime.
1. As described in the procedure for “Program Effects set-
tings” on page 69 of the Owner’s manual, set IFX1 to
064: L/C/R BPM Delay. Verify that you’re hearing a
delay effect.
2. Access the Prog P8: IFX– IFX1 page.
Now, we can set the Dmod to change the delay level via the
Joystick
3. Set Input Level Dmod to +100.
4. Set Source to JS+Y: #01.
The delay sound will disappear.
The input level to the effect can be controlled by the joystick.
As you move the joystick away from yourself, the delay
sound will gradually increase.
In addition, we can use Dmod to change the feedback level
via SW1
5. In the P1: Basic/Ctrls– Controllers Setup page, set the
SW1 function to SW1 Mod.CC#80, and the Mode to
Toggle.
Choose P8: IFX page. Set the Feedback Src to SW1: #80, and
set Amt to +30.
