Stereo Random Filter - Korg microARRANGER Owner's Manual

a: Frequency Bottom, a: Frequency Top
The sweep width and direction of the wah filter are deter-
mined by the "Frequency Top" and "Frequency Bottom" set-
tings.

b: Sweep Mode
This parameter changes the wah control mode. Setting
"Sweep Mode" to Auto will select an auto-wah that sweeps
according to envelope changes in the input signal level. Auto-
wah is frequently used for funk guitar parts and clav sounds.
When "Sweep Mode" is set to D-mod, you can control the fil-
ter directly via the modulation source in the same way as a
wah pedal.
When "Sweep Mode" is set to LFO, the effect uses LFO to
sweep in cycle.
c: Envelope Sens (Envelope Sensitivity)
This parameter sets the sensitivity of auto-wah. Increase the
value if the input signal is too low to sweep. Reduce the value
if the input signal is so high that the filter is stopped temporar-
ily.
c: Envelope Shape
This parameter determines the sweep curve for auto-wah.

value = 0...–100
d: LFO Frequency [Hz], e: BPM/MIDI Sync
When "BPM/MIDI Sync"=Off, the LFO speed uses the LFO
Frequency parameter setting. When "BPM/MIDI Sync"=On,
the LFO speed follows the "BPM", "Base Note", and "Times"
settings.
e: BPM, e: Base Note, e: Times
One cycle of LFO sweep is obtained by multiplying the length
of a note ( ... ) (selected for "Base Note", in relation to the
tempo specified in ("BPM", or the MIDI Clock tempo if "BPM"
is set to MIDI) by the number specified in the Times parame-
ter.

010: Random Filt

(Stereo Random Filter)

This stereo band pass filter uses a step‐shape waveform
and random LFO for modulation. You can create a spe‐
cial effect from filter oscillation.

a: LFO Waveform, c: LFO Frequency [Hz], 
d: LFO Step Freq (Frequency) [Hz]
When "LFO Waveform" is set to Step-Tri, LFO is a step-
shape, triangle waveform. The "LFO Frequency" parameter
sets the original triangle waveform speed. Changing the "LFO
Step Freq" parameter enables you to adjust the width of the
steps.
