section 4: lfos and s&h
an entire section on various lfo pointers
4.1 setting up lfo and s/h triggers:
(from using_a6_public.txt)
LFO:
The LFO's Clock (Rate knob) will start upon each keystroke if VOXTRG: ON VOX. Turn FREERUN:
-ON- and the LFO will be cycling upon each note but the phase will be free-running. If VOXTRG: ON
TRIG and TRIG: ON and Freerun: OFF, then the Clock will start upon the first received Trigger from
the Mod. Add Freerun and the LFO will start clocking but it's phase will be self-determined. Note:
Any Triggers received after the Clock starts, when the LFO is -not- in Freerun, will reset the LFO's
phase to the position determined by the Phase parameter.
To have an LFO in Freerun and always have it modulating—
Trig: Off, VOXTRG: ON VOX, FREERUN: -ON-.
To start the LFO clocking upon a Trigger—
Trig: On, VOXTRG: ON TRG, FREERUN: -ON- or -OFF-.
To start the LFO upon each keystrike beginning at the same phase point:
Trig: Off, VOXTRG: ON VOX, FREERUN: -OFF-.
SAMPLE AND HOLD:
As with the LFO, a Trigger can either start the Clock (Rate knob) and subsequent Triggers reset it's
cycle, or have the Clock off and use Trig to initiate single samplings of the S/H Input Source.
To have the S/H Clock start upon each keystrike—
Trig: Off, TRGSMP: Off, VOXTRG: -ON-.
To have the S/H Clock start upon a Trigger and reset it's Clock cycle upon each subsequent
Trigger:
Trig: ON, TRGSMP: Off, VOXTRG: OFF, and choose your Trigger Source.
To have the S/H initiate a single sampling upon a Mod Source Trigger:
Trig: ON, TRGSMP: ON, VOXTRG: OFF
4.2 getting a fast lfo (greater than 25hz):
Unfortunately, due to hardware limitations, the LFOs cannot go past 25Hz, as Mike Peake
pointed out:
I certainly have an interest in slow stuff like that.. I'm the guy who insisted that the LFOs be able to
go as slowly as they do (but the hardware is what limits the upper rate, which we looked into
opening even 10Hz more, but with large modulations you could hear the digitization, too much so
we kept it where it was--sorry).
The envelopes actually run on a much faster cycle than the LFOs. The envelopes also loop.
This means, if you want that faster-than-25Hz cycle on the LFOs, there is a way!
