9.1.4. LFO Waveforms
The
Wave/Load
knob selects from the following waveforms:
•
Sin
: Sine
•
Tri
: Triangle
•
Saw
: Sawtooth
•
Sqr
: Square
•
SnH
: short for
Sample and Hold, which refers to a waveform that randomly
changes its value.
•
SlewSnH
: like SnH, but with
slew, meaning each new cycle's voltage change
happens with a slight "glide" to the new value rather than changing instantly.
•
ExpSaw
: a sawtooth wave where the wave falls on an exponential curve rather
than a straight line – the initial drop is slightly quicker, but slows at the end. This
waveform is unipolar.
•
ExpRamp
: as above but a ramp wave. Also unipolar.
•
Shaper
: a waveform determined by the Shaper (see below) or loaded by the
Load knob.
If you're having trouble imagining these waveforms and what they do, just check the
Display while choosing a wave. The illustrations are very helpful.
As shown in the graphic on the Display, a sawtooth wave is usually defined as starting with a vertical
jump followed by a gradual drop until the start of the next cycle. Sometimes this is called a "falling
sawtooth". On the other hand, a cycle that begins with a gradual rise, followed by a vertical drop at the
end of the cycle, is known as a
ramp wave, or "rising sawtooth". If you want to use a ramp wave as a
modulator, use the sawtooth but apply a negative modulation.
9.2. The Shaper and LFO Wave Edit
Sometimes it can really benefit the sound design of a particular program to have a
waveform that's more complex than the usual choices. On the MiniFreak, you can create,
save, and load your own custom LFO waveforms using the Shaper.
9.2.1. Storing and loading Shaper Waves
The MiniFreak contains a library of Shaper Waves that can be loaded for instant use. There
are 16 Factory and 8 User Shaper Waves; storing a User Shaper Wave makes it available for
any preset. Before storing and loading those shaper waves, please first turn the Wave knob
clockwise until you reach LFO1 Wave Shaper.
Shift-turning the Wave/Load encoder scrolls through the list of Shaper Waves. The first one
shown is the one for that Preset (if any), then the 16 Factory waves, then the 8 User waves.
Each wave's shape is shown in the Display for quick reference. To load a chosen wave, just
release the Shift button.
