ACCESS VIRUS OS4

LFOs

mode, one LFO controls several 
voices so that the modulation will 
affect several voices in the same 
way. This which will make the 
effect stand out in the mix.

When this function is activate, the 
given LFO will no longer oscillate 
freely; instead, it restarts its wave 
cycle at the beginning of each 
note.

Next to the obligatory OFF posi-
tion, this parameter has 127 further 
increments. These let you chose 
different positions within the wave 
cycle at which the LFO will start 
oscillating at the start of each 
note.

In contrast to ENV mode (which is 
available independently of KEY 
TRIG PHASE), an LFO with KEY TRIG 
PHASE will continue to oscillate 

once it has been triggered. In other 
words, in behaves like a “real" LFO 
rather than an envelope.

This triggering option will also 
work when the LFO is synced up to 
the master clock. This means that 
synced LFOs can be triggered via 
note-on messages. The LFO rate, 
however, is still determined via the 
master clock and/or MIDI clock.

You can also trigger an LFO at any 
time by means of a controller, in 
other words, restart its waveform 
cycle via remote control. LFO1 
mode (Ctr #70), LFO2 mode (Ctr 
#82) and LFO3 mode provision con-
trollers that you can use for this 
purpose (Parameter B 9, see the 
parameter documentation in the  
“Appendix” on page 251).
