12. FX AND MIXER PARAMETERS
HPF
HPF sets the cutoff frequency of the reverb high-pass filter that affects the audio going in to the reverb.
LPF
LPF sets the cutoff frequency of the reverb low-pass filter that affects the audio going in to the reverb.
12.4 CHORUS
(SEND FX PAGE 3)
The chorus can be used to widen sounds, enhance the stereo image or add subtle movement to sounds.
DPTH
Depth sets the depth of the LFO modulation of the chorus.
SPD
Speed sets the speed of the LFO modulation of the chorus.
HPF
High-pass filter sets the highpass filtering of the input signal.
WDTH
Width sets the stereo width of the chorus.
VOL
Chorus Volume sets the volume of the Chorus output signal. Use LEVEL/DATA to set this parameter.
DEL
Delay Send sets how much of the wet chorus signal to send through to the delay.
REV
Reverb Send sets how much of the wet chorus signal to send through to the reverb.
12.5 COMPRESSOR
(MIXER PAGE 1)
The Compressor master effect compresses the dynamic range of the signal by reducing the volume of loud
sounds relative to the quiet sounds. There are eight parameters with which the compressor is customized
on this page. There is a bar on the left side of the screen that visually represents the amount of compres­
sion.
THR
Threshold sets the threshold of the compressor. A lower threshold means a larger portion of the signal
are subject to compression.

12. FX AND MIXER PARAMETERS
ATK
Attack sets the time of the compressor attack phase, i.e. how quickly the compressor responds to loud
peaks.
REL
Release sets the time of the compressor release phase, i.e. how long it takes for the compression to
recover in quieter moments.
MUP
Makeup Gain sets the makeup gain of the compressor output, to compensate for the reduced signal
levels caused by compression. The Makeup Gain parameter value is displayed in dB.
VOL
Pattern Volume sets the kits overall audio level. This parameter basically has the same function as the
MAIN VOLUME knob, but is saved together with the kit. Use LEVEL/DATA to adjust the settings.
RAT
Compression Ratio. There are eight different compression ratios, 1.50, 2.00, 3.00, 4.00, 6.00, 8.00, 16.00
and 20.00. Higher ratios result in greater compression of the signal.
SCS
Sidechain Source decides what audio source the compressor analyzes when it performs sidechaining.
Sidechaining is the process when the compressor uses the output of an audio source to control the
overall action of the compressor. For example, if you set SCS to TRK1 where you have a kick drum, every
time the kick drum plays, the compressor lowers the overall sound of the mix.
COMP MIX sets the sidechain source to be all the tracks that are routed to the compressor.
NOT COMP sets the sidechain source to be all the tracks that are not routed to the compressor.
MAIN sets the sidechain source to be the sound sent to the Main (L/R) outputs.
TRK1–16 sets the sidechain source to be the sound sent from one of the separate audio tracks.
IN LR sets the sidechain source to be the sound coming from IN L/R.
IN L sets the sidechain source to be the sound coming from INPUT L.
IN R sets the sidechain source to be the sound coming from INPUT R.
•	 The results of the COMP MIX and NOT COMP settings depends on the selections
you make on the COMPRESSOR ROUTING page. For more information please see
“9.8.1 KIT” on page 37.
•	 The IN L and IN R options are only available if you set DUAL on the External mixer
page to ON. The IN LR option is only available if you set DUAL to OFF. For more infor­
mation, please see “12.9 EXTERNAL MIXER” on page 66.
SCF
Sidechain Filter filters the signal from the sidechain source before the compressor analyzes it. The
parameter ranges from a low-pass filter to a high-pass filter. Negative parameter values sets a low-pass
filer. Positive parameter values sets a high-pass filter.
When set as a low-pass filter, the compressor reacts mostly to bass frequencies. Use this setting for a
characteristic pumping compressor sound. When set as a high-pass filter, the compressor reacts less to
bass frequencies. Use this setting to avoid pumping.
DRY/WET MIX
Dry/Wet Mix sets the mix of the uncompressed signal and the compressor output signal. A setting of
0 results in a completely uncompressed signal. A setting of 127 lets only the compressed signal pass
through. All values in between mix the uncompressed signal with the compressed signal, which is known
as parallel compression.

12.6 INTERNAL MIXER PAGE 1
(MIXER PAGE 2)
The INTERNAL MIXER page 1 is where you can access the TRACK LEVEL parameter of track 1–8 (if they
are audio tracks).
VOL
Pattern Volume sets the patterns overall audio level. This parameter can be used to balance the volume
between different patterns and is saved together with the kit. Use LEVEL/DATA to adjust the settings.
12.7 INTERNAL MIXER PAGE 2
(MIXER PAGE 3)
The INTERNAL MIXER page 2 is where you can access the TRACK LEVEL parameter of track 9–16 (if they
are non-MIDI tracks).
VOL
Pattern Volume sets the patterns overall audio level. This parameter can be used to balance the volume
between different patterns and is saved together with the kit. Use LEVEL/DATA to adjust the settings..
