Using The Dynamic Modulation Function - Korg A1 Owner's Manual

Using the Dynamic Modulation Function

Using Dynamic Modulation
to control the Chorus
Using a pedal to control the speed
The Dynamic Modulation function allows 'real time" control of effect parameters using
MIDI data, volume pedals and input level envelopes.
The external controller is called the Dynamic Source and the parameter that it controls is
called the Dynamic Parameter.
Using the Chorus effect as an example, pedals or MIDI data can be used to control the
modulation speed and effect level.
(Select a factory program 31 or refer to page 16 and edit factory program I 99 to include
Chorus.)
Effect Name
1. Press the EDIT key to enter the EDIT SELECT menu.
Press the double function editor below the CHO (Chorus) effect, to enter
Parameter Edit, and then press the PAGE+ key until the last page of
parameters (arrow down) is shown. Please note that not all effects have this
Dynamic Modulation page.
2. Rotate the "B" double function edit control to select the Dynamic
Parameter, "SPEED". Some effects may have only one Dynamic
Parameter.
3. Rotate the "D" double function edit control to select the Dynamic
Source, "PEDAL".
Connect a volume pedal (output) to the rear panel Param. Pedal input.
Please note that. OFF, ENV, of LFO cannot be selected as Dynamic
Sources in some effects.
4. Rotate the "P double (unction edit control to set the Dynamic
Amount.
The higher the value the more the parameter can be varied by the Dynamic
Source. (Pedal in this case). A parameter control "direction" can be
specified by selecting a positive (+) or negative (-) Dynamic Amount value.
For example, selecting a "+" or "-" setting, when using a PEDAL to control
Chorus SPEED, specifies whether the SPEED will become faster or slow
down when you press on the pedal. (See the diagram on the next page.)
