Mod Wheel
As you play the keyboard, use the Mod wheel to control the depth of low-
frequency oscillator (LFO 1 and/or LFO 2) modulation, or depth of the
chorus. The Mod wheel is also monophonic: it simultaneously increases the
modulation level within all voices.
The Mod wheel is not spring-loaded and does not have a detent. If the Mod
wheel is unused, or if it is used and left fully down, minimum modulation
occurs.
For more information, see Section 9, which covers the LFOs, and Section 10,
which covers the modulation system.
WAVEFORM MIX JOYSTICK
During performance you can use the joystick to modulate the mixture of the
four oscillators in the current program. This enables you to spontaneously
and dynamically modulate the timbre by reshaping complex waveforms
or introducing detunings. This real-time modulation occurs in addition to
the programmed action of the mixer envelope generator and other mixture
modulators.
Explore the eect of fast or slow movement throughout the joystick range.
CHORUS LEFT/RIGHT
The stereo chorus circuit (analog delay line) enriches the sound and can be
switched on and o independently for either output channel. This is handy for
stereo eects, as well as Split or Double modes where you might not want
both programs to be chorused.
ALTERNATE RELEASE FOOTSWITCH
The ALTERNATE RELEASE footswitch is usually programmed to simulate the
action of a piano’s sustain pedal. It does this by switching between two rate
values for the envelope generator release stages (rates k and kA). When the
footswitch is disconnected or up, releasing a key engages the original (and
usually shorter) rate 4. When the footswitch is connected and held down,
this selects the alternate release value 4A (for all three envelope generators),
which is usually programmed to be noticeably slower (longer) than the original
release rate.
AUX FOOTSWITCH
The AUX footswitch is used exclusively for real-time control over the
arpeggiator. If the footswitch is pressed while arpeggiating, notes are latched
into a “sequence” which can be recalled for playback later.
