EXS24 mkI Modulation Paths
Many of the hard-wired modulation paths that were available as sliders on the original
EXS24 (mkI) are now integrated into the modulation router. To reconstitute the
modulation slider configuration of the mkI version, open the Options pop-up menu in
the upper-right corner of the interface and choose “(Recall Default EXS24 mkI Settings).”
This will load the mkI modulation paths into the modulation router, as follows:
• Velocity to Sample Select
• LFO 1 to Pitch via ModWheel (= Ctrl#1)
• Velocity to Sample Start (inv)
• LFO 2 to Filter Cutoff via ModWheel
• Velocity to Filter Cutoff
• Envelope 1 to Filter Cutoff via Velocity
• LFO 2 to Pan via ModWheel
You can, of course, freely alter the settings of these modulation paths—allowing you
to use modulation sources that were unavailable in the EXS24 mkI, for example (see the
end of this section for tables of all sources and destinations).
Note: For technical reasons, the settings of the modulation router cannot translate
backward to the EXS24 mkI.
Getting to Know the EXS24 mkII LFOs
The EXS24 mkII includes three LFOs (low frequency oscillators) that can be used as
modulation sources. They are all available as sources or destinations in the router. If you
are new to synthesizers, and the concept behind LFOs, see Using the LFO to Modulate
Sounds.
LFO 1 is polyphonic, which means that if it is used for any modulation of multiple voices,
they will not be phase-locked. Furthermore, LFO 1 is key-synced: Each time you play a
key, the LFO 1 modulation of this voice is started from zero.
To understand the non-phase-locked characteristic more fully, imagine a scenario where
a chord is played on the keyboard. If LFO 1 is used to modulate pitch, for example, the
pitch of one voice might rise, the pitch of another voice might fall, and the pitch of a
third voice might reach its minimum value. As you can see, the modulation is independent
for each voice, or note.
The key sync facility ensures that the LFO waveform cycle always starts from zero, which
results in consistent modulation of each voice. If the LFO waveform cycles were not
synchronized in this way, individual note modulations would be uneven.
LFO 1 can also be faded in or out automatically, courtesy of a built-in envelope generator.
