FILTER / MODULATION
FILTER SLOPE
By default, the Subsequent 25 Filter rolloff is set to the
classic Moog 24dB-per-octave slope. You can change
this setting in real time as you play, making the change
in slope part of your performance.
To change the Filter slope, engage Shift mode and press
the BANK 2 and PATCH 1 buttons. Use the four lowest
notes on the keyboard to select the slope. Pressing low C
selects a 1-pole, 6dB-per-octave slope. Pressing low C#
selects a 2-pole, 12dB-per-octave slope. The low D key
selects a 3-pole, 18dB-per-octave slope, and low D#
selects the default 4-pole, 24dB-per-octave slope.
MODULATION PARAMETERS
Shift mode also lets you determine several modulation parameters, including the waveform modulation
destination, LFO Range, LFO pitch tracking, and whether the LFO syncs to tempo.
WAVEFORM MODULATION DESTINATION
To change how waveform modulation is routed, enter
Shift mode and press the BANK 2 and PATCH 2 buttons.
Then use the three lowest keys to specify whether
waveform modulation will be applied to Oscillator 1
(press the C key), Oscillator 2 (press the C# key), or
both Oscillators (press the D key). Note that the WAVE
AMT knob must be turned up for waveform modulation
to have an effect.
LFO RANGE
The Subsequent 25 LFO has three selectable ranges:
0.01 to 10Hz, 0.1 to 100Hz, and 1 to 1000 Hz. Although
the Mixer has no audio input for the LFO, an audio-
frequency oscillator can be very useful as a modulation
source, allowing Subsequent 25 to produce classic,
clangorous FM (frequency modulation) tones.
In Shift mode, press the BANK 2 and PATCH 3 buttons
to change the LFO’s range. Press the low C key to assign
the LFO to its lowest frequency range, from 0.01 to 10Hz.
Press C# to assign the LFO to its middle range, from 0.1
to 100Hz. Press the D key to assign the LFO to its upper
range, from 1 to 1,000Hz.
NOTE: No matter which range you choose, modulation
at normal vibrato rates (between 5 and 10Hz) is possible.
