ERRATUMFLTR page 2 knob letters are never printed and do not line up

§12.6 describes the six FLTR page 2 parameters (DEL, SPRD, KEY.T, BASE, WIDTH, RSET) without stating any knob letters, while Appendix B lists FILTER page 2 destinations on knobs A, C, D, E, F and H — skipping B and G. The join cannot be made without guessing, so the parameter records number the slots A–F in the manual's listing order and the mod-destination map leaves the “knob H” row unlinked (fltr2.sprd therefore shows no mod-destination badge). Unresolved pending hardware.

12. AUDIO TRACK PARAMETERS
ATK
Attack Time sets the length of the attack phase of the filter envelope.
DEC
Decay Time sets the length of the decay phase of the filter envelope.
SUS
Sustain Level sets the sustain level of the filter envelope.
REL
Release Time sets the length of the release phase of the filter envelope.
FREQ
Frequency sets the cutoff frequency of the Multimode filter and the center frequency of the EQ.
RESO
Resonance sets the resonance behavior of the filter. Resonance introduces a peak in the spectrum at
the cutoff frequency.
TYPE
Type morphs the Multimode filter from low-pass to band-pass to high-pass.
ENV
Env. Depth determines the amount of modulation the filter envelope applies to the cutoff frequency. The
knob is bipolar, offering both negative and positive modulation depths.
12.6 FLTR PAGE 2
On FLTR page 2, you will find the parameters that control the Base-width filter and several parameters that
affect the Multimode filter on FLTR page 1. The parameters described here are for the Single Player, Multi
Player, and the Subtracks SRC machines. The Grainer and Shape machines do not have any FLTR PAGE 2.
The Base-width filter is a high-pass filter and a low-pass filter connected in series. The filters BASE and
WDTH parameters define the Base-width filter’s frequency range.
Examples of how the BASE and WDTH parameters affect the filter frequency range:

• With BASE set to 0, the filter functions as a low-pass filter with WDTH adjusting the fre
quency range.
• With WDTH set to 127, the filter functions as a high-pass filter with BASE adjusting the
frequency range.
• With WDTH set to 0, the filter functions as a band-pass filter with BASE adjusting the
frequency.
• With BASE set to 0 and WDTH set to 127, the filter does not affect the sound.

12. AUDIO TRACK PARAMETERS
DEL
Envelope delay sets the time before the attack phase of the filter envelope starts. This parameter is part
of the filter envelope that controls the FLTR machine. You can also press and hold [FUNC] and then turn
DATA ENTRY knob A to access this parameter from FLTR page 1 quickly. This parameter only affects the
Multimode filter on FLTR page 1.
SPRD
Frequency Spread offsets the filter cutoff frequency in the left and right channels.
KEY.T
Keytrack sets how much the filter cutoff frequency is affected by what note is playing. The higher the
KEY.T setting, the more the filter opens up at higher notes. This parameter is only available for the Single
Player and Multi Player machines.
BASE
Sets the base frequency of the filter.
WIDTH
Sets the frequency width above the base frequency.
RSET
Envelope Reset sets the filter envelope behavior. This parameter only affects the Multimode filter on
FLTR page 1.
ON resets the envelope for each consecutive trig. The envelope’s attack phase is reset to zero.
OFF does not reset the envelope for each consecutive trig (default). The envelope’s attack phase con
tinues from where it was left off.
12.7 AMP PAGE
The AMP page controls parameters for the amplitude envelope, panning, and volume.
ATK
Attack Time sets the length of the attack phase of the amp envelope.
HOLD
Hold Time sets the length of the hold phase of the amp envelope. Fixed Hold time values (0–126) specify
the length of the hold phase, and the envelope ignores Note Off events such as Trig Length, releasing
a [TRIG] key, or a key on an external controller. Setting HOLD to NOTE means the hold phase will be
determined by Note On and Note Off events. This parameter is only available if ENVELOPE MODE in the
TRACK SETUP menu is set to AHD.
If you set HOLD to NOTE and use an external keyboard to trigger the envelope, the sound
will be sustained (if DEC is set to a value less than 127) for as long as you press a key on
the keyboard.
DEC
Decay Time sets the length of the decay phase of the amp envelope. When ENVELOPE MODE is set to
AHD, DECAY works as the REL parameter, defining the time from end of HOLD to 0.
SUS
Sustain Level sets the sustain level of the amp envelope. This parameter is only available if ENVELOPE
MODE in the TRACK SETUP menu is set to ADSR.
