Sound Parameters – Filter Types

Filter Types

This paragraph describes the Q’s different filter types. Most types are based on traditional low pass,

high pass or band pass structures.

Bypass

Use this setting to bypass the filter. This is useful if you want to disable the filter temporarily and listen

to the pure oscillators’ signals.

24dB Low Pass and 12dB Low Pass

The low pass types 24dB LP and 12dB LP are suitable for the most usual applications. Use the 24dB

slope if you want to create sounds with a typical audible filtered character, use the 12dB slope if you

want to get softer results.

PPG LP Lowpass

The PPG LP is a resonance lowpass filter with a slope rate of 24dB per octave. Its characteristics were

modeled after the legendary PPG Wave synthesizer and its integrated SSM 2044 chip. The resonance

of the SSM 2044 had a very special tonal character, which has not been implemented in this way in

any other filter circuit or IC. If you have the chance to directly compare the original with the Q, you

will find the resonance (or Emphasis, as it´s called in the PPG) of both to be nearly identical.

 When using the PPG LP Filter type Filter FM isn´t possible. The cause is that the original filter

circuit also didn´t have FM.

24dB Band Pass and 12dB Band Pass

The band pass filters 24dB BP and 12dB BP remove frequencies both below and above the cutoff

point. As a result, the sound character gets narrow. Use these filter types for programming effect and

percussion-like sounds.
