The Pre Filter Mix<br />
The outputs of the oscillators, as well as a few other signal sources,<br />
are fed into a virtual mixing board called the Pre Filter Mix. The<br />
job of this mixer is to funnel all of these sources into the inputs of<br />
the next sound processing stage—the filters. For each source, you<br />
can specify its level, which is how loud it should be, and its balance,<br />
which determines how much of it goes to Filter 1 and how much<br />
to Filter 2.<br />
The Filters<br />
The sound produced by the oscillators is very raw, and usually not<br />
suitable to be used directly in an instrument. In order to bring out<br />
the sonic textures you have in mind, you will typically want to<br />
dampen certain harmonics and boost others. This is where the<br />
filters come in. Filters alter the frequency content of the signal,<br />
and can have a drastic effect on the sound. A filter typically allows<br />
you to adjust its cutoff frequency, which represents the range of<br />
harmonics that the filter operates on, as well as its resonance, which<br />
determines how much boost is given to harmonics around the<br />
cutoff frequency. Each of the <strong>Micron</strong>’s voices contains two filters,<br />
and each filter can be one of eighteen different types, each with its<br />
own character and sonic flavor.<br />
The Post Filter Mix<br />
The outputs of the filters need their own virtual mixing board as<br />
well, and that’s what the Post Filter Mix is for. For each filter<br />
output, as well as a pre filter signal of your choice, you can specify<br />
a level, which is how loud it should be, and a pan, which determines<br />
how much goes to your left speaker and how much to the right.
