3–2: Filter 1 Mod (Filter 1 Modulation)

3–2: Filter 1 Mod (Filter 1 Modulation)
Here you can modify the sound by applying modulation to the cutoff frequency of filter 1 (oscilla-
tor 1).
This tab page will be displayed if “3–1a: Routing” has a setting other than thru. If this setting is
single, the parameters for filter 1B will not be displayed.
3–2a: Filter 1A Modulation
These settings specify how Keyboard Tracking, Joy Stick (X), Aftertouch, and Alternate Modula-
tion will affect the cutoff frequency of filter 1. (This will produce a “wah” effect.)
Cutoff Freq Key Track (Cutoff Frequency Keyboard Track)
The following Key and Ramp parameters will specify how keyboard position affects the cutoff fre-
quency (refer to the diagram on the next page).
Key (Keyboard Track Keys)
Specify the note numbers at which keyboard tracking will begin to apply. Between the Low and
High settings, the cutoff frequency will change in correspondence to the keyboard location (pitch).
• Low (Low Key) [C–1…G9]
Keyboard tracking will apply to the range below the specified note number.
The note number can also be specified from the keyboard.
• High (High Key) [C–1…G9]
Keyboard tracking will apply to the range above the specified note number.
The note number can also be specified from the keyboard.
Ramp (Ramp settings)
Specify the angles of the keyboard tracking.
• Low (Lower Ramp) [–99…+99]
• High (Higher Ramp) [–99…+99]
With a setting of +62, the angle of change (i.e., slope or tilt) for the cutoff frequency will be the
same as the keyboard location (pitch). This means that the oscillation that occurs when the reso-
nance (“3–1b: Filter 1A”) is raised will track the keyboard position.
With a setting of –43, the cutoff frequency will have no slope; i.e., the cutoff frequency will be the
same for all notes.
