Oscillators
Detune Knob
Sets the detune amount in Cents for the selected Oscillator 1,2
or 3. If it is set fully clockwise, Oscillators pitch will be 50 cents
sharper than its basic pitch, fully anticlockwise and it will be 50
cents flat.
Slight detuning between each Oscillator will enrich the sound by
introducing a beating between the Oscillators (in the same way
a 12-string guitar sounds richer than a 6-string). Bass and lead
sounds can be fattened up using a small amount of detune.
Large amounts of detuning will lead to more extreme effects.
Semitone
Raises or lowers the selected Oscillators pitch in semitone
increments up to a full octave. By setting the pitch of Oscillator
1 to zero and adjusting the pitch of Oscillator 2 and 3 by differ-
ing amounts results in some musically pleasing intervals.
Settings 5 (a perfect 4th), 7 (a perfect 5th), 3 (minor 3rd), 4
(major 3rd), 8 (minor 6th) and 9 (major 6th) offer the best
results.
Mod Env Depth Knob
Controls the amount of pitch modulation to the currently select-
ed Oscillator from the Mod Envelope. In the centre position
there is no effect on the oscillator's pitch, anticlockwise the
effect is negative (i.e. the pitch drops and then rises) and clock-
wise positive (the pitch rises and then falls).
See Page 22 - Amp and Mod Envelopes, for the setting of the
rise and fall times.
LFO1 Depth Knob
Controls the amount of pitch modulation to an Oscillator from
LFO 1. It controls how much above and below the basic pitch
the Oscillator regularly rises and falls. If the LFO is set to
Triangle wave and the LFO’s speed knob is above the centre of
its range, this will produce a vibrato effect. Other effects like a
siren or sea gull cry are possible with more extreme settings.
