Modulation Wheel
The Modulation wheel can be set to simultaneously control a number of param-
eters. You can set positive or negative values, just like in the Velocity Control
section. The following parameters can be affected by the modulation wheel:
Legato
Legato works best with monophonic sounds. Set Polyphony (see below) to 1
and try the following:
D Hold down a key and then press another key without releasing the
previous.
Notice that the pitch changes, but the envelopes do not start over. That is,
there will be no new “attack”.
D If polyphony is set to more voices than 1, Legato will only be ap-
plied when all the assigned voices are “used up”.
For example, if you had a polyphony setting of “4” and you held down a 4
note chord, the next note you played would be Legato. Note, however, that
this Legato voice will “steal” one of the voices in the 4 note chord, as all the
assigned voices were already used up!
Retrig
This is the “normal” setting for playing polyphonic patches. That is, when you
press a key without releasing the previous, the envelopes are retriggered, like
when you release all keys and then press a new one. In monophonic mode, Re-
trig has an additional function; if you press a key, hold it, press a new key and
then release that, the first note is also retriggered.
Portamento (Time)
Portamento is when the pitch “glides” between the notes you play, instead of in-
stantly changing the pitch. The Portamento knob is used to set how long it takes
for the pitch to glide from one pitch to the next. If you don’t want any Portamento
at all, set this knob to zero.
Setting Number of Voices - Polyphony
This determines the polyphony, i.e. the number of voices a Subtractor Patch can
play simultaneously. This can be used to make a patch monophonic (=a setting
of “1”), or to extend the number of voices available for a patch. The maximum
number of voices you can set a Subtractor Patch to use is 99. In the (unlikely)
event you should need more voices, you can always create another Subtractor!
! Note that the Polyphony setting does not “hog” voices. For exam-
ple, if you have a patch that has a polyphony setting of ten voices,
but the part the patch plays only uses four voices, this won’t mean
that you are “wasting” six voices. In other words, the polyphony set-
ting is not something you need to consider much if you want to con-
serve CPU power - it is the number of voices actually used that
counts.
About the Low Bandwidth button
This can be used to conserve CPU power. When activated, this function will re-
move some high frequency content from the sound of this particular device, but
often this is not noticeable (this is especially true for bass sounds).
| Parameter | Description
F. Freq This sets modulation wheel control of the Filter 1 Frequency pa-
rameter. A positive value will increase the frequency if the wheel
is pushed forward. Negative values invert this relationship.
F. Res This sets modulation wheel control of the Filter 1 Resonance
parameter. A positive value will increase the resonance if the
wheel is pushed forward. Negative values invert this relation-
ship.
LFO 1 This sets modulation wheel control of the LFO 1 Amount pa-
rameter. A positive value will increase the Amount if the wheel is
pushed forward. Negative values invert this relationship.
Phase This sets modulation wheel control of the Phase Offset param-
eter for both Osc 1 and 2. Note that Phase Offset Modulation
(Subtraction or Multiplication) must be activated for this to have
any effect (see page 103).
FM This sets modulation wheel control of the FM Amount parame-
ter. A positive value will increase the FM amount if the wheel is
pushed forward. Negative values invert this relationship. Both
oscillators must be activated for this to have any effect.
