LFO-Start-Modes
The way an LFO is started depends on the overall function mode of the
LFO, which makes it a bit complicate, but tremendously versatile:
In LFO Poly and LFO Single mode (not host synced) the LFO-Start-Modes
are
Phase the LFO starts with every note as set with the Phase dial
Free
the LFO starts with every note at an almost random phase
Pha/M (Phase Mono) is here like described in “Phase” above
In LFO Mono mode (all voices share the LFO) the meaning is
Phase the LFO always runs, its Phase is in accordance with the Phase
parameter. An example: When you set Phase to 0 and Tempo to
¼ th Note the LFO will start right on each quarter. However, when
you set Phase to 25% it means that its shifted by 25% (or 90
degree) of its cycle, so each full cycle of the LFO wont start at the
quarter but 1/16
th note before (or you can think of it still starting at
the quarter, but not at the start of the full cycle, but instead 25%
later, for a Sine that would be the maximum positive value).
Free here the LFO simply is always right in sync with the host tempos
and song position, its equivalent to the Phase mode just described,
when Phase is set to 0. It is never re-triggered.
Pha/M is an extension to the Phase mode, it is like that, but the LFO is
restarted with every first Note being played after a pause. So
whenever you play a note after a pause, the LFO will start at that
moment, with the Phase as adjusted with the Phase dial and it will
remain in that resulting total phase offset from now on. Actually this
mode is harder to describe than to explore, so please try it. It is
usually used with the Voices being set to Mono (see page 75 for a
description of the Voices parameter)
Note: With random waveforms (last row of waveforms) the Start.Mode has
no effect on the random waveform or its start-phase.
The Delay parameter sets the time before the LFO begins running. A Delay
setting of 0 means that the LFO begins operating immediately.
Delay is not just suppressing the LFO, the LFO indeed only starts after the
Delay is over, so when you set a start-phase with the Phase dial, keep in
mind that Delay affects this.
Delay in only active when the LFO not runs in Mono mode (host synced)
The Attack dial setting determines the length of time it takes for the LFO to
