Vermona PERfourMER MKII - quad analog synthesizer - Manual (Page 16)

Modulation Generator (LFO)
The LFOs (Low Frequency Oscillators) allow creating cyclic repeating modu-
lations of the oscillators and filter. The PerFourMer MKII's LFOs offer a
choice of functions that might not be seen at first glance: Its LFOs can be
synchronized to each other and/or to a MIDI-clock. Also, they can be
shifted against each other in phase.
The available control elements and parameters per LFO are:
Picture 4: The LFO
WAVE
This switch selects the LFO waveform. Choices are Sample & Hold (ran-
dom), sine ( ) descending saw tooth and rectangle (
).
SPEED/PHASE
This control carries out two resp. three different functions. Depending
on the SYNC-switch position and/or the parameter setting for LFO MIDI
CLOCK it controls
• the LFO's speed (frequency)
• the waveform's phase (not for synthesizer channel 1) or
• the MIDI-clock division
In unsynchronized mode, SPEED/PHASE controls the LFOs' speed/fre-
quency within a range of 0.05Hz (approx. 20 seconds for a full cycle) to
250Hz.
Find details about LFO SYNC and LFO MIDI CLOCK SYNC in the next
chapter.
