6.10 Wavetable Play Modes
Wavetable instruments can be created in Tracker Mini. This emulates
classic wavetable synthesizers by using a sample as the wavetable source.
Standard Tracker Mini samples can be used 'out of the box' or samples
prepared specifically to suit the application in a wavetable synth and give
better performance. The Tracker Mini wavetable synthesis brings a simple
yet different creative option into the instrument library.
What is Wavetable Synthesis?
The most common synth model is subtractive synthesis. This is based on a
sound source, typically using one or more oscillators, tuned in various
ways. The sound is then shaped and carved by filtering out (subtracting)
frequencies, applying envelopes and adding effects. Wavetable synths
typically follow these same principles but the 'oscillator' is formed from a
series of wave-shapes called wavetables. In reality, a wavetable consists of
a set of stacked samples called frames, the standard being 256 frames.
Navigating or modulating through the almost endless wave positions and
selecting 'single cycles' in the wavetable is a fundamental element in
wavetable sound design. In Tracker Mini the wavetable size (samples per
frame) is set by the 'Window' parameter. Think of this as the length of the
available table, the default maximum being defined by the original audio
sample format. The 'Position' within the wavetable is also selectable and
important in the sound design process. Position can also be modulated.

NOTES
Wavetable Parameters
The wavetable play mode is a simplified application of wavetable synthesis
and consists of two core parameters. The Window is the wavetable length
(samples per frame) and has a maximum value based on the original file.
The position parameter is what enables the creative sound design and
audio manipulation. This can be manually adjusted to find a sweet spot or
modulated with the envelope or LFO.
