Filter and Amplifier Settings

The lower part of the edit display contains the filter and amplifier settings.

Filter Section

Filter Shape

  • LP 24, 18, 12, and 6 are low-pass filters with 24, 18, 12, and 6 dB/oct. Frequencies above the cutoff are attenuated.

  • BP 12 and BP 24 are band-pass filters with 12 and 24 dB/oct. Frequencies below and above the cutoff are attenuated.

  • HP 24, 18, 12, and 6 are high-pass filters with 24, 18, 12, and 6 dB/oct. Frequencies below the cutoff are attenuated.

  • BR 12 and BR 24 are band-reject filters with 12 and 24 dB/oct. Frequencies around the cutoff are attenuated.

  • AP is an all-pass filter with 18 dB/oct. Frequencies around the cutoff are attenuated.

Cutoff

Controls the cutoff frequency of the filter.

Resonance

Emphasizes the frequencies around the cutoff. At higher settings, the filter self-oscillates, which results in a ringing tone.

Distortion

Adds distortion to the signal. The following distortion types are available:

  • Tube adds warm, tube-like distortion.

  • Hard Clip adds bright, transistor-like distortion.

  • Bit Reduction adds digital distortion by means of quantization noise.

  • Rate Reduction adds digital distortion by means of aliasing.

  • Rate Reduction Key Follow adds digital distortion by means of aliasing, but with Key Follow. The rate reduction follows the keyboard, so the higher you play, the higher the sample rate.

Envelope Amount

Controls the cutoff modulation from the filter envelope.

Cutoff Velocity

Controls the cutoff modulation from velocity.

Cutoff Key Follow

Adjusts the cutoff modulation using the note number. Increase this parameter to raise the cutoff with higher notes. At 100 %, the cutoff follows the played pitch exactly.

Filter Envelope Section

Attack

Controls the attack time of the filter envelope.

Decay

Controls the decay time of the filter envelope.

Sustain

Controls the sustain level of the filter envelope.

Release

Controls the release time of the filter envelope.

Amplifier Section

Level

Controls the overall volume of the sound.

Velocity

Controls the level modulation from velocity. At 0, all notes are played with the same level.

Amplifier Envelope Section

Attack

Controls the attack time of the amplifier envelope.

Decay

Controls the decay time of the amplifier envelope.

Sustain

Controls the sustain level of the amplifier envelope.

Release

Controls the release time of the amplifier envelope.
