The Vector Sequencer has two CV inputs (
Mod1
and
Mod2
) that can
be used to control a variety of parameters such as gate time, velocity
scaling or the probability for chance operations. The input voltage range
is -5 to +5V. Each of the 8 parts of the Vector has two modulation
busses that can listen to either or both of the external modulation
inputs.
To navigate to the external modulation page, press
Mod
, then turn

to navigate over to the fifth modulation page.
To setup external modulation for a part:
1. Pick a mod source (
EXT1
for Mod1,
EXT2
for Mod2, or
OFF
).
2. Pick a target parameter.
3. Set the amount of modulation, which ranges from -100% to 100%.
For most parameters, 50% is a good starting point. At 100% the
amount of modulation will be enough to range from the smallest value
for the parameter to the largest.
Modulation Targets:
PIT2
:
Pitch mod, 2 octave range.
PIT5
:
Pitch mod, 5 octave range (approx 1V/oct).
POCT
:
Pitch mod, octaves only.
P712
:
Pitch mod, octaves and fifths.
VELN
:
Velocity mod, narrow range.
VELW
:
Velocity mod, wide range.
GATE
:
Gate time.
STLN
:
Step Length.
STRP
:
Step Repeat.
RCHT
:
Number of ratchets.
PROB
:
The probability amount for
Chance Ops
.
STRT
:
Start step.
LEN
:
Sequence length.
DIR
:
Sequence direction.
RATE
:
Sequence rate.
For all targets, modulation is calculated at the start of each step. The
current value for the modulated param is read and then adjusted up or
down based on the input voltage and modulation amount. Parameters
with CV modulation will display a super-script
X1
or
X2
.
TIP: For best results, it helps to know what the voltage range of your
modulation source is. Attenuator modules (or cables) and level shifters
(for bipolar voltages) can be handy for getting a CV source into the -5 to +
5V range of the Vector’s modulation inputs.
TIP: Using a VCA controlled by a pitch or velocity CV from the Vector can
be both a handy and interesting way to control the voltage level of a CV.
