Dynamic modulation, Common FX LFO

Dynamic modulation (Dmod)

Dynamic modulation (Dmod) lets you use MIDI
messages or the KROME's controllers to modulate
specific effect parameters in real‐time.
Dynamic modulation to control an effect pa-
rameter 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 settings" on page 79, set IFX1 to 078: L/C/R
BPM Delay. Verify that you're hearing a delay
effect.
2. Access the Prog P8: Routing/IFX– IFX1 page.
Now, we can set the Dmod to change the delay
level via the Joystick
3. Set Input Level D‐mod 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 feed-
back level via SW1
5. In the P1: Basic/Controllers– Controllers Setup
page, set the SW1 function to SW1 Mod.CC#80,
and the Mode to Toggle.
Choose P8: Routing/IFX– IFX1 page. Set the Feedback
Src to SW1: #80, and set Amt to +30.
82
When you move the joystick away from yourself and
press the SW1 button, the feedback level will increase,
and the delay sound will continue for a longer time.
The Amt setting specifies the feedback level that will
be in effect when the SW1 button is pressed. If Amt is
set to –10, pressing the SW1 button will reduce the
feedback level to 0.
Finally, we can use the MIDI/Tempo Sync
function to synchronize the delay time to the
arpeggiator tempo.
6. Set BPM to MIDI.
7. For L, C, and R, set the Delay Base Note and Times
as desired.
For this example, set Delay Base Note to and Times
to x1 so that the effect will be easily understandable.
The delay time will repeat at an interval of a 8th note.
8. Rotate the TEMPO knob, and the delay time will
change.
When you (push the joystick away from yourself and)
press the SW1 button, the feedback level will rise, and
the delays will become longer.
9. When you turn on the ARP button, arpeggiator
will begin playing.
Select any desired arpeggiator. When you rotate the
TEMPO knob, the delay time will change in
synchronization with the changing tempo of the
arpeggiator.
Depending on the specific delay effect, you may
hear some unexpected noise if you change the
tempo while the delay is sounding. This is because
the delay sound becomes discontinuous, and is not
a malfunction.
For some effects, you can synchronize the LFO
frequency to the tempo. Set the effect parameters
MIDI Sync to On, and BPM to MIDI. For details,
please see page 236 of the Parameter Guide.
