Using LAG
Since the LAG Processor is one of the 27 Modulation Sources, it is used in
the Patch the same as any other Source. As an example, say you were using
LFO4 to modulate the FREQ of VCO2 directly but decided that you want to
Lag LFO4 instead:
STEP1: Press the VCO2 button.
STEP 2: Press the switch beneath FREQ in the display. Since you were
already using LFO4 to modulate the frequency of VCO2, LFO4
along with its corresponding Amount will then be displayed.
STEP 3: Press the switch beneath LFO4 in the top window so that it
becomes underlined then, using the buttons in the MODULATION
SOURCE Section, select LAG as the new Modulation Source.
STEP 4: Enter FM/LAG Page.
STEP 5: Select LFO4 as the LAG IN.
STEP 6: Start with a LAG RATE of 0, then adjust the Rate gradually higher.
As you increase the amount of LAG RATE, you will begin to hear
LFO 4's waveform being smoothed by the LAG Processor.
STEP 7: For varied LAG processing, press PAGE 2 and experiment with
using different LAG MODEs.

LAG MODE This parameter gives you a choice among the three response
modes of LAG:
LEGATO When this mode is used, LAG will be active only when notes
going to a particular Voice are played Legato (playing a
new note without immediately releasing the first note). No
Portamento will be heard while playing Staccato (playing a
new note only after the first note has been completely
released). This permits LAG to be used expressively,
depending on how the Keyboard is played. When LEGATO
is off, all Voices will LAG.
NOTE: This mode is most useful when playing only one
Voice or if the Zone is in UNISON. Putting the Zone in a
polyphonic Keyboard mode requires very careful - and
sometimes impossible - keyboard technique. As an extreme
example of this, if the MATRIX-12 is set to play all 12 Voices
polyphonically, causing all 12 Voices to Lag requires that 24
keys be depressed momentarily.
Another way of stating this is that since Lag affects the
transition between notes per Voice, there will only be a Lag
effect if a new note is sent to a Voice that is already
playing (already "gated").
