LFO
Rate & Sync
The Rate parameter controls the rate or speed of the LFO’s cycle. If the
Sync button is enabled, BPM-based units are used. When the Sync button is
disabled, the Rate control is adjusted in Hz.
The state of the Sync button also dictates how Cypher and Strobe’s built-in
arpeggiator Rate is set.
Phs (Phase)
The Phase parameter allows you to adjust the phase of the LFO between 0
and 360 degrees. Phase can be modulated in real time, and always resets
when the LFO is gated.
Mode
The Mode control selects the LFO shape and can be modulated via the TransMod system. Note that modulating this
control is liable to result in audible clicks.
The following ‘standard’ LFO shape modes are available:
• Sine
• Cosine
• Tri-S • Tri-C
• Arc-S
• Arc-C • Saw-Up
• Saw-Down
• Square
A number of other LFO shapes are available:
• Stab-White
• Stab-Pink
• Stab-Brown The various noise types provide random points to which the LFO ‘jumps’. After it
reaches the next point, it drops down vertically to the position of the previous point.
This process then repeats. The end result is a series of sharp ‘stab’ shapes.
• SnH-White
• SnH-Pink
• SnH-Brown These modes are sample+hold values taken from noise sources. They create
‘steppy’ sounding random LFOs, because each value stays constant until the next
value, at which point the LFO immediately travels vertically to the new value.
• Ramp-White
• Ramp-Pink
• Ramp-Brown In these modes, the LFO ramps up or down to the next value – the end result is
somewhat like a complex triangle shape but with random amplitudes.
• White noise
• Pink noise
• Brown noise These are straightforward noise sources for use as an LFO, that output noise
values continuously at control-rate.
Mono
Enabling this button forces the LFO into monophonic mode. In monophonic mode, there is only 1 global LFO instead of an
LFO for each voice.
Swg (Swing)
This is an unusual control for an LFO to possess. It creates a ‘swung’ feel by changing the length of each part of 2 LFO
cycles so that each cycle has a different length, but their combined length remains the same.
