08.1 LFO Shape
- The Shape button selects one of six waveforms: sine, triangle, rising sawtooth, rectangle (square), random (sample and hold), or random gliding (smoothed random).
Note/Info The square wave has a 50% duty cycle: it stays high for half of each cycle.
- The Random wave creates random modulations. For a familiar science-fiction computer sound, select Random, set the LFO speed to about 4 Hz, choose the LFO-to-Pitch crossing in the Matrix, then set the modulation amount to about 30.
- Random gliding is a slewed random wave. Its pitch changes gradually between random values, unlike the abrupt changes of the Random wave. Routing it to oscillator pitch makes the modulation amount easier to fine-tune before applying it to another target.
Note/Info Matrix modulation on the MicroFreak is bipolar: it can affect a target in both positive and negative directions. This offers more sound-design options, though a slow negative modulation of the Analog Filter can make the sound inaudible for part of the cycle.
