G. LFO/ SAMPLE AND HOLD
The Voyager has a dedicated LFO and SAMPLE and HOLD. The LFO produces triangle and
square waves that oscillate from .2 to 50 Hz. There are triangle and square wave outputs that can
be selected as Modulation sources in the Mod Busses. The square wave is routed to the Sample
and Hold trigger input, and the noise source is routed to the sample and hold input. For each
cycle of the LFO, the voltage at the input of the sample and hold circuit is held until the next
trigger event. Noise is a random signal, so the voltage that appears at the output of the sample
and hold is a random voltage that changes in time with the LFO.
LFO RATE:
The LFO Rate control sets the Rate of the dedicated LFO. The range of oscillation is
.2 Hz to 50 Hz.
LFO SYNC:
The LFO Sync switch sets the trigger method for starting the LFO waveform.
OFF/SYNC: This setting allows the LFO to be free running,
MIDI: Allows the division of the MIDI clock signal set up in the EDIT mode function “MIDI CLK Divider”
to retrigger the LFO. Note the LFO is analog, and does not automatically sync to MIDI clock - it is
restarted much in the manner oscillator sync works, and does not defeat the Rate control.
KB: Allows the LFO to be retriggered when a Note On is received.
ENV. GATE: Allows the Envelope Gate Source to restart the LFO.
