LOW FREQUENCY OSCILLATORS
Each of the 6 tracks in the Monomachine offers 3 interlaced low frequency oscillators
(LFO’s), which can be used to modulate any track parameter. A typical application of an
LFO is to let it sweep a filter cut-off frequency. The 18 interlaced LFO’s offer 11 waveforms
and 5 trig modes. The LFO’s are tied to their specific tracks, and are shared between the
internal sequencer and the midi sequencer. The speed of the LFO’s is synchronised to the
global tempo.
First select a track using the [TRACK] keys that you want to alter the LFO’s for. Then use
the [DATA PAGE] keys to locate one of the three LFO pages. All the three LFO’s of the
track are identical. The <DATA ENTRY> LED’s indicate which DATA page is currently
selected, and the DATA ENTRY knobs control the parameters of the DATA page selected.
LFO CONTROLS
The three LFO’s of each track are identical. They can control any parameter of the track for
the internal or the MIDI sequencer, as well as the other LFO’s. The LFO control interface is
printed below:
PAGE (page) selects which DATA page the LFO targets.
DEST (destination) chooses the parameter from the DATA page chosen by the PAGE that
is modulated. All seven DATA pages, plus the MIDI sequencer are accessible by the LFO’s.
There’s also a special pitch page, PTCH. If the DEST is PTCH 8 destinations are available,
offering various ranges to allow for both subtle vibrato and full range frequency sweeps.
TRIG (trig mode) is an important parameter for getting the most out of the LFO's. The trig
modes are described in the list below, and their function is visualised in combination with
the waveforms in Figure 3 on page 32.
•
FREE = The LFO is running continuously, never restarting or stopping.
•
TRIG = The waveform is restarted for each LFO-trig, and then runs continuously.
•
HOLD = The waveform is running free in the background, but the output LFO level is
latched for each LFO-trig and held still until the next LFO-trig.
•
ONE = The waveform is restarted for each LFO-trig, then runs for one cycle and finally
stops and holds the last LFO level.
•
HALF = The waveform is restarted for each LFO-trig, then runs for one half cycle and
finally stops and holds the last LFO level.
WAVE (waveform) selects the waveform for the LFO from the eleven shapes available.
There are 5 basic shapes plus mirrored copies of all but the RND random (“RND”) shape.
Select the appropriate waveform with the WAVE knob.
MULT (multplier) multplies the SPD parameter by the set amount of times.
