• PHASER-LFO
• PHASER-ENV
A phaser effect. 2, 4, 6 and 8 pole phasers are available, each with positive or negative feedback,
via the
Mode parameter.
• COMB-LFO
• COMB-ENV
A comb filter effect. There are only 2 possibilities for the Mode parameter: positive and negative.
• Filter LFO controls
All the LFO filters share the same control layout:
Freq (-48 to 72 semitones)
The cutoff frequency, tuned in semitones relative to A4.
Res (0 to 100%)
The resonance of the filter at the cutoff frequency.
Mode
MG-Filter:
L1, L2, L3, L4, B2, N2, H1
SV-Filter: L2, L4, H2, H4, B2, B4, N2, N4, P2, P4, A2, A4
Phaser: P2+, P2-, P4+, P4-, P6+, P6-, P8+, P8-
Comb: positive / negative
Rate (units depend on Sync parameter)
The rate of the LFO modulating the filter cutoff. The units of this control depend on the setting
of the Sync parameter. If Sync is set to seconds, the rate is adjustable from 0.03Hz to 128Hz. If
Sync is set to BPM, the rate is adjustable from 16 notes to a 256
th note, with normal, triplet and
dotted note settings available.
Sync (seconds or Beats)
Sets the time base to either seconds/milliseconds or BPM sync values (following the GURU
tempo).
Shape
The LFO shape, switchable between Sine, Cosine, Tri-Sine, Tri-Cosine, Arc-Sine, Arc-Cosine,
Saw-Up, Saw-Down, Square, Sample & Hold Pink, Sample & Hold Brown, Ramp-White, Ramp-
Pink and Ramp-Brown LFO shapes.
Depth (0 to 100%)
The amount of modulation applied to the cutoff frequency by the LFO.
Spread (0 to 100%)
The stereo spread of the LFO.
