SHAPE
This parameter sets the shape and phase of the currently selected LFO, as indicated around
the dial. Available shapes are Sine (up first), Sine (down first), Triangle (up first), Triangle (down
first), Ramp up, Ramp down, Square (high first) and Square (low first).
DEST
This parameter sets the LFO destination. The available destinations are:
•
AMP -
Overall sound amplitude
•
FRQ -
Current note frequency
•
CUT -
Filter cut off frequency
•
FM -
Amount of FM
•
MIX -
Mix between OSC1 and OSC2
•
PWM -
Pulse width of OCS1 (PWM must be selected as OSC1 wave)
Note: In normal operation, the top LED indicates the status of the LFO wave, to help
you keep track of how the sound is being modulated.
LFO
CRAFTsynth features an LFO with 8 waveforms and 6 destinations, which can be synced to
MIDI clock. This feature can be used to create a huge array of sound modulations, including
generating extra harmonics through AM and FM.
DEPTH
The DEPTH control affects the depth of the LFO modulation. The LFO modulation works
differently for each destination to get the most versatility from the synthesis engine.
•
AMP -
LFO modulates overall amplitude from full volume down to LFO depth, where
maximum depth is silence.
•
FRQ -
LFO mod/- LFO depth around current note frequency.
•
CUT -
LFO maximum depth is current filter cut off.
•
FM -
LFO maximum depth is current FM Amount.
•
MIX -
LFO mod/- LFO depth around current OSC Mix.
•
PWM -
LFO mod/- LFO depth around current OSC1 PW.
RATE
This control sets the rate of the LFO, and its behavior depends on the presence of MIDI clock.
If there is no MIDI clock detected:
In the first half of the dial, the frequency is set freely from 0.1 HZ to 20Hz.
If there is MIDI cock detected:
The first half of the dial sets the LFO frequency to divisions of the host BPM.
In the second half of the dial, the LFO rate is set to a division of the main frequency of the
note being played. This allows the LFO frequency to run into the audible range and maintain
harmonious modulations. A massive array of effects can be achieved in this way, including
AM and FM.
