First Steps
Some typical patch configurations
are already available to you
through Mavis’s internal routing.
As a short exercise, let’s recreate
one of those using the patch bay.
Say you would like a nice little trill with each
note. You can achieve this by patching the
LFO to change the VCO’s pitch.
MAKE THIS CONNECTION
Connect the LFO output to the 1V/OCT input
and then press a key on the keyboard to
trigger a note.
The LFO, however, swings from -5 volts
to +5 volts—resulting in a trill spanning 10
octaves! Since that is likely too extreme for
most uses, Mavis has an attenuator, which
is like a volume knob for a control voltage.
MAKE THIS CONNECTION
Patch the LFO output to the ATTN (+5)
(attenuator) input and then patch the
ATTN (attenuator) output to the VCO’s 1 V/
OCT input.
With the attenuator knob fully clockwise
you will hear the same 10-octave trill, but
as you lower the attenuator knob that
range will diminish until there is almost no
modulation.
NOW YOU HAVE 3 KNOBS THAT SHAPE
THE TRILL/VIBRATO EFFECT:
ATTENUATOR: Controls the interval of the
trill (i.e. modulation depth)
LFO RATE: Controls the speed of the trill
LFO WAVE: Moves from a vibrato (triangle)
eect to a trill (square)
This patch, however, is already present in
Mavis’s internal routing. After unpatching
everything, all you need to do is set the
VCO MOD MIX knob fully clockwise to LFO
and the PITCH MOD AMT knob will set the
depth of the modulation.
→Let’s now use the patch bay to do some
things you can only do through patching.
