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 device, 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 ac-
cess to an Expression Pedal or a Breath controller, you can use these to modulate pa-
rameters. 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:

Description
F. Freq This sets External modulation control of the Filter 1 Frequency pa-
rameter. A positive value will increase the frequency with higher ex-
ternal modulation values. Negative values invert this relationship.
LFO 1 This sets External modulation control of the LFO 1 Amount parame-
ter. A positive value will increase the LFO 1 amount with higher ex-
ternal modulation values. Negative values invert 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 rela-
tionship.
FM This sets External modulation control of the FM Amount parameter.
If a positive value is set, the FM amount will increase with higher ex-
ternal modulation values. A negative value inverts this relationship.
Both oscillators must be activated for this to have any effect.
