"All digital oscillators have a basic problem called “Aliasing”. Aliasing occurs when the oscillator’s harmonics are too high for the sample-rate to deal with, thus creating a side-effect called aliasing. Aliasing adds inharmonic frequencies to the oscillator making it sound dirty and grungy. Most oscillators employ aliasing filters to filter out those frequencies. The Alisaw oscillators use that "problem" as a musical flavor that can be an advantage at times.
FleXor’s Non-Band-Limited oscillators have a linear ramp shape (Saw Up). The dropdown from their maximum to minimum takes 1 sample. The accurate linearity and the fast dropdown give these oscillators a rock-solid sound, ideal for tasks which need high precision. While having their advantages, NBL oscillators have their disadvantages. Therefore, FleXor has two kinds of NBL oscillators, each specialized for different things.
A perfect sawtooth with no aliasing. This oscillator plays only
frequencies that do not alias. It has a wide spectrum resulting in
a pure and clean sound. The side-effect is that high notes
gradually drift out of tune. This oscillator is perfect for punchy
bass sounds, and for higher detuned pads.
A perfect aliasing sawtooth. This saw oscillator can track the
frequency range accurately, leading to a side-effect of aliasing. The oscillator has a wide spectrum
with a grungy and dirty sound. The dirt amount and its character can be determined by the “saw
division” control on the oscillator. If shaped to triangle or sine, the aliasing frequencies will
disappear. When shaped to sine or triangle aliasing will dramatically diminish.
FleXor also has a shaping section that allows you to shape the saw into the classic waveforms:
triangle, sine and pulse.
FleXor's NBL oscillators are able to sync with sample accurate precision, making
them ideal for sync sounds and for retriggering punchy bass sounds and percussive
sounds. The oscillator's fast response makes them excellent for FM manipulation as
well. Their accurate shape makes them perfect for use with wave-shapers, which may
reduce the aliasing depending on the shape." (Flexor Manual)
