Extended LFO Settings
Selecting between saw tooth and square waveforms
EDIT-Parameter 7 allows changing of the LFO's first waveform. Edit function
LFO WAVE 1: SQUARE can select between square or descending saw tooth.
This selection is available for each synthesizer channel.
The default setting as well as the reset default (see "RESET", page 30) for the
first LFO-waveform is saw tooth. To switch to a square waveform, follow
these steps:
1. Press the EDIT-button.
2. Select parameter 7: LFO WAVE 1: SQUARE using the SELECT/SEQ
control.
3. Press TRIG to enable the square waveform for one or several synthe-
sizer channels. The corresponding red LED above each TRIG-button
will display the selected square waveforms. If the LED is not lit, the saw
tooth is selected. Changes are audible immediately.
4. Exit edit-mode by pressing the EDIT-button.
LFO SYNC
The LFOs of synthesizer channels 2,3 and 4 can be synchronized in fre-
quency to the prior module. To do so, switch SYNC for that synthesizer
channel to the right LFO setting.
In this case, SPEED/PHASE will no longer control the LFO's speed but its
waveform phase between 0° and 180°. Set fully to the left (0°), the synthe-
sizer channel's LFO will run in phase with the prior located synthesizer
channel's LFO. Set fully to the right (180°), both LFOs are out of phase and
shifted by a half-cycle. Waveforms can still be selected independently for
each synthesizer channel.
NOTE What sounds cumbersome in theory, is easy to
understand in practice. Simply try the sync-function.
You will come across interesting complex rhythmic
modulation patters very quickly.
With LFOs being synchronized by another LFO and the MIDI-clock, the LFO
sync has priority. Here, SPEED/PHASE controls the waveform's phase, not
the MIDI-clock divider.
