SUBTRACTOR SYNTHESIZER

116

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, Retrig 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

instantly 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 an-

other 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

setting is not something you need to consider much if you want to

conserve 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

remove some high frequency content from the sound of this particular de-

vice, but often this is not noticeable (this is especially true for bass sounds).

External Modulation

Subtractor can receive common MIDI controller messages, and route these

to various parameters. The following MIDI messages can be received:

• Aftertouch (Channel Pressure)

• Expression Pedal

• Breath Control

If your MIDI keyboard is capable of sending Aftertouch messages, or if you

have access to an Expression Pedal or a Breath controller, you can use

these to modulate parameters. The “Ext. Mod” selector switch sets which of

these message-types should be received.

These messages can then be assigned to control the following parameters:

Destination

Description

F. Freq This sets External modulation control of the Filter 1 Fre-

quency parameter. A positive value will increase the fre-

quency with higher external modulation values. Negative

values invert this relationship.

LFO 1 This sets External modulation control of the LFO 1 Amount

parameter. A positive value will increase the LFO 1 amount

with higher external modulation values. Negative values in-

vert this relationship.

Amp This let’s you control the overall volume of the sound with

external modulation. If a positive value is set, the volume

will increase with higher external modulation values. A

negative value inverts this relationship.

FM This sets External modulation control of the FM Amount

parameter. If a positive value is set, the FM amount will in-

crease with higher external modulation values. A negative

value inverts this relationship. Both oscillators must be ac-

tivated for this to have any effect.
