Connections Flipping the Subtractor around reveals a plethora of connection possibilities, most of which are CV/Gate related. Using CV/Gate is described in the chapter “Routing Audio and CV”. Audio Output This is Subtractor’s main audio output. When you create a new Subtractor device, this is auto-routed to the first available channel on the audio mixer. Sequencer Control The Sequencer Control CV and Gate inputs allow you to play the Subtractor from another CV/Gate device (typically a Matrix or a Redrum). The signal to the CV input controls the note pitch, while the signal to the Gate input delivers note on/off along with velocity. For best results, you should use the Sequencer Control inputs with monophonic sounds. Modulation Inputs Remember that CV connections will not be stored in the Subtractor patch, even if the connections are to/from the same Subtractor device! These control voltage (CV) inputs (with associated voltage trim pots), can modulate various Subtractor parameters from other devices, or from the modulation outputs of the same Subtractor device. These inputs can control the following parameters: • Oscillator Pitch (both Osc 1 & 2). • Oscillator Phase Offset (both Osc 1 & 2). • FM Amount • Filter 1 Cutoff • Filter 1 Res • Filter 2 Cutoff • Amp Level • Mod Wheel Modulation Outputs The Modulation outputs can be used to voltage control other devices, or other parameters in the same Subtractor device. The Modulation Outputs are: • Mod Envelope • Filter Envelope • LFO 1 Gate Inputs These inputs can receive a CV signal to trigger the following envelopes. Note that connecting to these inputs will override the normal triggering of the envelopes. For example, if you connected an LFO output to the Gate Amp input, you would not trigger the amp envelope by playing notes, as this is now controlled by the LFO. In addition you would only hear the LFO triggering the envelope for the notes that you hold down. The following Gate Inputs can be selected: • Amp Envelope • Filter Envelope • Mod Envelope
