Select Waveform
The Subtractor has two oscillators that can be usedas sound sources for your patches
Tuning
Mix: Left = Osc 1Right = Osc 2
Activate Osc 2
Follow keyboard pitchWhen off, all keys play the same pitch
Frequency Modulation
Ring Modulation
Oscillators
Each oscillator has two phase modes Multiply and subtract
Phase amount
Two waves played out of phaseresults in a very different wave
Noise
The noise generator can be used in place of Osc 2.
Decay works before the amp EG
Pink noise (0) accentuates low frequenciesWhite noise (0) includes all frequencies at equal amplitude
Use noise for percussion and other non-pitched soundsOr to add a noise component to a pitched sound.
FiltersSubtractor has two resonant filters. Filter 1 is a multi-state filter. Filter 2 is a Low Pass Filter.
Low Pass 4 poleLow Pass 2 poleHigh Pass 2 poleBand Pass 2 poleBand Reject (notch)
Filters can be linked orindependent. When linkedLPFs act as a 6 pole filter
Cutoff Frequency
Resonance accentuatesthe cutoff frequency
For Notch and Band passFilters, resonance controlfunctions as Cutoff freq 2.
Envelope Generators
EGs are used to change a signal over time.
ADSRAttack Time - How long it takes to reach full volumeDecay Time - Time it takes to move from full volume to the Sustain LevelSustain Level - Sustained level, continues until key is releasedRelease Time - Time it takes to go from Sustain level to silence after key is released.
Amp and Filter EGs are hardwired. Mod EG can modulate different devices.
Amount of modulation can be attenuated on Filter and Mod EGs
Invert EG signal
LFOsUnlike EGs, LFOs loop continuously
Sync to tempoFrequency
Mod Amt
Mod TargetWaveforms
Last two “waveforms”are random and functionas Sample-Hold.
Keyboard pitch can modulatethe LFO frequency
LFO signal can be delayed
Frequency and Ring Mod
Frequency modulation and Ring Modulation use an audible range oscillator to modulate the frequency of another.
More Modulation
Key velocity is used to modulatethese parameters.
Pitch Bend can be set to 1-12 half steps
Wheels can be played manually, automated or by CV
Mod wheel canbe assigned to various parameters
Aftertouch andMIDI CC 11 (Expression) and CC 2 (Breath) can also be used as a mod source
