EXi: AL-1 Analog Synthesizer

AMS [List of AMS Sources]
This selects a modulation source to control the Output
Level. For a list of AMS sources, see “AMS (Alternate
Modulation Source) List” on page 967.
Intensity [–99…+99]
This controls the depth and direction of the Output
Level modulation.
Frequency [00…99]
This controls the cutoff frequency of Filter A, in
increments of 1/10 of an octave. The specific effect of
the cutoff frequency will change depending on the
selected Filter Type, as described above.
Frequency Fine [-99…+99]
This provides fine control of the filter cutoff frequency.
Each step of this parameter is equal to 1/100 of a step
of the main Frequency parameter, above.
Resonance Type [Standard, High]
This controls the strength of the filter resonance when
the Filter Routing is set to 24dB/oct. When the routing
is set to Single, Serial, or Parallel, this parameter is
grayed out.
Standard provides the resonance character of a typical
analog 4-pole filter.
High creates a more pronounced resonance.
Resonance Bass [Tight, Full]
This controls the character of the filter resonance at low
cutoff frequencies. Its effect is most noticeable with
high Resonance settings.
Tight produces a more restrained resonance, similar to
a classic, American, wood-paneled monophonic
synthesizer.
Full produces a wide, boomy resonance, reminiscent of
a famous five-voice American synthesizer.
Resonance [00…99]
Resonance emphasizes the frequencies around the
cutoff frequency.
When this is set to 0, there is no emphasis, and
frequencies beyond the cutoff will simply diminish
smoothly.
At medium settings, the resonance will alter the timbre
of the filter, making it sound more nasal, or more
extreme.
At very high settings, the resonance can be heard as a
separate, whistling pitch.
To make the resonance track the keyboard pitch, see
“Key Follow,” on page 189.
Resonance Mod by AMS [List of AMS Sources]
This selects a modulation source to control the
Resonance amount. For a list of AMS sources, see
“AMS (Alternate Modulation Source) List” on
page 967.
Intensity [–99…+99]
This controls the depth and direction of the Resonance
modulation.
Pan [Random, L001…C064…R127]
This controls the stereo pan for Filter A’s output. It is
available only when Filter Routing is set to Parallel.
When the Filter Routing is set to Single, Serial, or
24dB/oct, the Pan parameters will be grayed out.
AMS [List of AMS Sources]
This selects an AMS source to modulate Pan. For a list
of AMS sources, see “AMS (Alternate Modulation
Source) List” on page 967.
Intensity [–99…+99]
This controls the depth and direction of the Pan AMS
modulation.
5–1c: Filter B
Filter B is available when the Filter Routing is set to
Serial or Parallel. Otherwise, its parameters will be
grayed out.
Filter B is almost the same as Filter A, but without the
Multi Filter mode, and with the addition of the Link
controls, as described below. For all other parameters,
please see the descriptions under “5–1b: Filter A,” on
page 185.
Link [Off, On]
When Link is On, most of Filter B’s parameters are
grayed out, and are instead controlled by the settings
for Filter A.
Specifically, Filter B will use Filter A’s settings for
Resonance, Resonance Bass, and all Frequency and
Resonance modulation settings. Filter B’s Frequency is
also linked to that of Filter A, with an optional
frequency offset via the Link Frequency Offset
parameter, below.
The Bypass, Type, Input Trim, Output Level, Output
Level AMS, Pan, and Pan AMS parameters are still
controlled separately.
Link Frequency Offset [–99…+99]
This offsets Filter B’s Frequency from that of Filter A,
and applies only when Link is On.
When Link is Off, this parameter is grayed out.
