Keytrack Lets you enable or disable key tracking for the oscillator. When Keytrack is enabled, the pitch of the
oscillator is determined by the MIDI note number (before any alteration by the Coarse and Fine tuning set-
tings). When Keytrack is disabled, the pitch of the oscillator is determined solely by the Coarse and Fine tuning
settings and remains constant regardless of the MIDI note number.
Coarse Adjusts the bipolar tuning of the oscillator from concert pitch (A = 440 Hz). The range is from –36 semi-
tones to +36 semitones. The Coarse Tune for Oscillator 1 can also be edited using MIDI CC 29.
Fine Adjusts the bipolar tuning of the oscillator from concert pitch (A = 440 Hz). The range is from –50 to +50
Cents. The Fine Tune for Oscillator 1 can also be edited using MIDI CC 61.
Osc3 > FM Determines the amount of frequency modulation (FM) applied to Oscillator 1 from Oscillator 3.
Depending on the interval (frequency ratio) between the oscillators and the amount of frequency modulation
applied, you can greatly increase the harmonic complexity of a sound with FM. Use this with the Sync control
to enhance harmonic complexity even more. You can adjust the amount of frequency modulation using the
Osc 3 > 1 FM knob on the top panel Performance Control matrix (knob 1, row 2), as well as using MIDI CC 50.
Waveshape Controls the Venom Waveshaper function as applied to Oscillator 1, which can be used for PWM
(pulse width modulation) depending on the chosen waveform. The width of the pulses is determined by the
threshold set by the Waveshape parameter (Off, 0–127). If the input waveform amplitude is greater than the
positive threshold level, the output is set to full positive amplitude. If the input waveform amplitude is less
than the positive threshold, the output is set to full negative amplitude. When used with a sawtooth wave,
modulating the Waveshape parameter generates classic PWM, but we encourage you to try other input wave-
forms as they can produce interesting and varied results.
Oscillator 2
Oscillator 2 has all of the same parameters as Oscillator 1, except for the FM Amount and Waveshape settings.
Additionally, Oscillator 2 has an Oscillator Sync toggle.
Waveform Lets you select the Waveform for Oscillator 2. The Waveform can also be selected using NRPN 017BH
(see “Oscillator 1” on page 43).
Keytrack (See “Oscillator 1” on page 43.)
Coarse Can be edited using MIDI CC 30 (see “Oscillator 1” on page 43).
Fine Can be edited using MIDI CC 62 (see “Oscillator 1” on page 43).
Osc1 Sync When enabled, synchronizes the waveform start of Oscillator 2 to the waveform start of OSC 1.
Try using the Waveshape control with a Sawtooth wave (rather than a Square wave) for the most audible effects.
