PRESET PROGRAMMING

The Tone filter is a simple low-pass tone control which can be used to

darken the tone of an instrument. The Z-Plane filter is an ultra-

powerful synthesizer filter which can dramatically alter the sound of

an instrument.

To understand how a filter works we need to understand what makes

up a sound wave. A sine wave is the simplest form of sound wave. Any

waveform except a sine wave can be analyzed as a mix of sine waves at

specific frequencies and amplitudes.

One way to represent complex waveforms is to use a chart with fre-

quency on one axis and amplitude on the other. Each vertical line of

the chart represents one sine wave at a specific amplitude and

frequency.
