like a chorusing effect. Turn it up more, and you’ll hear the entire waveform being canceled in rhythm
with the LFO. That’s because you’re pushing the pulse wave beyond its maximum width, so that the
waveform doesn’t have a chance to cycle back to its starting point. Applying LFO modulation to
pulse width is most useful at rates normally used for vibrato—usually between 6 and 9Hz.
In the MODULATION section, turn the SOURCE knob to the FILTER EG position and push the MOD
wheel up all the way. If you play the keyboard and the Filter Envelope is at its initialized setting,
you won’t hear anything until you release the keys. Again, that’s because the pulse width is pushed
beyond its maximum. Lower the MOD wheel to about halfway and play around with the Filter
Envelope settings to get a feel for the Envelope’s effect on pulse width.
GLOBAL PITCH CONTROLS
MIDI INDICATOR: This LED illuminates whenever Subsequent 25 receives MIDI
data through either its MIDI IN or USB PORT.
FINE TUNE: Rotating this knob will adjust the frequency of both Oscillators
as much as one semitone up or down from its center position. This feature
allows Subsequent 25 to be quickly tuned to match another instrument or a
previously recorded track that deviates slightly from standard pitch.
GLIDE RATE: Glide, also called portamento or glissando, causes smooth
pitch changes between notes. This knob specifies how much time it takes to
transition from one pitch to the next when you play the keyboard. Although
Glide is normally applied to every note you play when it’s engaged, you can
turn on Legato Glide using Shift mode (see Hidden Parameters on page 28).
OCTAVE BUTTONS: These buttons extend the Subsequent 25 keyboard
beyond its two-octave range. Pressing the left button once transposes the
Subsequent 25 pitch down an octave, and pressing it again transposes it down
another octave. Likewise, pressing the right button transposes the pitch up an
octave, and pressing it again transposes it up another octave. The illuminated
LED indicates the current transposition. The buttons also transpose the MIDI
Note Numbers that Subsequent 25 transmits by corresponding amounts.
Using the OCTAVE buttons gives the Subsequent 25 keyboard a six-octave
range. With a little practice, these buttons can even be pressed while
performing, in order to increase the available key range.
KEYBOARD: Subsequent 25 is equipped with a velocity-sensitive keyboard, so that all 25 keys transmit
MIDI velocity data in response to how fast the keys are depressed.
WHEELS: The PITCH and MOD wheels located to the left of the keyboard can contribute greatly to
the expressivity of your playing. Use the PITCH wheel to smoothly bend pitch during performance.
By default, it transposes pitch up two semitones and down two semitones. However, you can change
either interval in Shift mode (see Hidden Parameters on page 27). The PITCH wheel is spring-loaded
to automatically return to the center position.
The MOD wheel controls the depth of modulation. At its minimum setting, modulation is turned off.
At its maximum setting, modulation is at full throttle. The depth of the MOD wheel’s effect depends on
the settings of the PITCH AMT, FILTER AMT, and WAVE AMT knobs.
