The FREQUENCY knob sets the filter (cutoff) frequency. In simpler terms, the
filter frequency is like an overall tone control: as the value is increased the
higher frequencies/harmonics pass through and the sound transitions from
totally muted to an incredibly rich and textured brightness.
The
TRACK
switch selects the filter tracking (sometimes called Keyboard
Follow or Keyboard Scaling) to
FULL
,
OFF
, or
HALF
. Filter tracking applies
keyboard control voltage to the filter: more tracking, more brightness as you
ascend the keyboard, e.g., higher keyboard notes played result in brighter
notes heard. A
FULL
, tracking selection keeps the bass ‘n booty notes nice
and round and fades in a gradual sheen and sparkle to the lead line
wiggles and such up on top of the music.
The
RESONANCE
knob sets the filter resonance. The resonance, or “Q”
emphasizes, or boosts the cutoff frequency region and makes the presence
of harmonics more apparent. The MINI and 2600 filters will begin to
self-oscillate (oscillate and “howl,” or scream like amplifier feedback), and
may be used as a separate tone source, when the resonance value setting
passes ‘round “3 o’clock.” Resonance is in fact negative feedback (We
know this is true because Drew Neumann told us so, at the 2013 Winter
NAMM Show!) and is a signature sound of subtractive synthesis.
The
ENV DEPTH
(Envelope 1 Depth) knob sets
Envelope 1 amount. The pattern of the filter
envelope contouring is determined by the
Envelope controls: attack, decay, sustain, and
release; the amount or depth of the envelope
contouring is determined by this parameter.
The
MOD DEPTH
(Modulation Depth) knob sets the modulation amount of
the filter by
VCO 2
(Voltage Controlled Oscillator 2), or
LFO
(Low Frequency
Oscillator) via the switch to its left: the switch in its top position selects OSC
2, for audio frequency modulation (think vocal and metallic timbres/x-mod)
