Sound Parameters – Low Frequency Oscillators (LFO)
129 Waldorf Q User’s Manual
• The Sawtooth shape can generate interesting filter or volume changes. If you need a
modulation with inverted slope, just apply the Sawtooth shape with negative amount.
• The Random shape generates random values and glides to them linearly.
• S&H (Sample & Hold) samples a random value and holds it until the next value is
generated. If Speed is set to 0 , a random value is generated on each new note.
Speed 0…127 or 256 bars…1/96
Determines the frequency of the LFO signal. On low values, it might take several minutes until the
LFO performs a complete cycle while higher values are in the audible range. Very high values are
scaled in semitone steps. With
LFO Keytrack set to 100% , a Speed setting of 122 delivers an 8’ LFO
oscillation. 16’ oscillation can therefore be generated with a
Speed
setting of 110 and so on.
When the LFO Clocked parameter is set to On , you can adjust the LFO Speed in musical values. The
lowest possible value is 256 bars , meaning that a complete LFO cycle would need 256 bars.
Sync
Off, On
When Sync is set to On, the respective LFO phases of all voices are synced so that they sound as one
LFO. This can be interesting when the LFO is applied to modulate Filter Cutoff or Panning .
When Sync is set to Off , the LFO run independently which is better suited for pitch modulation to get
bigger sounds.
���
Sync does not mean that the LFO is synced to MIDI Clock or to note start. This is done with the
Clocked parameter or the Phase parameter.
Delay
0…127
The Delay parameter works differently depending on the setting of the Fade parameter in the LFO
display menu:
• When Fade is set to +00…+63 , the LFO signal output is zero for the time set with the
Delay parameter. After this time, the LFO is faded in and then runs with full magnitude.
• When Fade is set to –64…-01 , the LFO runs with full magnitude for the time set with the
Delay parameter. After this time, the LFO is faded out to zero.
LFO Edit Menu
The following parameters can be accessed via the display menu. Press the LFO section’s Edit button
to activate the display menu.
Keytrack -200%...+196%
Determines how much the speed of the LFO depends on the MIDI note number. The reference note
for Keytrack is E3, note number 64. For positive settings, the LFO speeds up on notes above the
reference note, for negative settings the LFO slows down when higher notes are played and vice
versa. A setting of +100% corresponds to a 1:1 scale, e.g. when an octave up is played on the
keyboard the LFO speed is doubled.
