Gene

Description

lfo_rate

Designates the LFO frequency. The LFO creates vibrato and tremolo effects.

lfo_amt

Adjusts the level of the vibrato / tremolo effect. Values less than 0.5 will turn off the LFO en-

tirely.

lfo_bal

Decides the balance between vibrato (pitch modulation) and tremolo (amplitude modulation).

0.0 = vibrato, 0.5 = both vibrato and tremolo, 1.0 = tremolo only.

a_form

Controls the waveform shape and timbre of Oscillator A. The waveform morphs gradually

from sine to sawtooth to square to pulse. (See Figure 11 Oscillator Waveforms.)

a_noise

Adjusts the mix of noise in Oscillator A. Higher settings will introduce noise and at 1.0 the

signal is entirely obscured by noise.

a_color

Changes the character of the noise in Oscillator A from a brown (muddy) noise to a white

(sharp) noise.

a_freq

Controls the pitch of Oscillator A. In practice, since Oscillator B and the filter cut-off fre-

quencies are linked to this setting, it determines the overall pitch of the sound.

a_mod

Is bipolar and determines the pitch modulation amount from the Envelope. 0.5 means no

pitch modulation. 0.0 is maximum negative and 1.0 is maximum positive modulation.

b_form

Controls the waveform shape and timbre of Oscillator B. The waveform morphs gradually

from sine to sawtooth to square to pulse. (See Figure 11 Oscillator Waveforms.)

b_noise

Adjusts the mix of noise in Oscillator B. Higher settings will introduce noise and at 1.0 the

signal is entirely obscured by noise.

b_freq

Controls the pitch of Oscillator B in relation to the pitch of Oscillator A.

b_mod

Is bipolar and determines the pitch modulation amount from the Envelope. 0.5 means no

pitch modulation. 0.0 is maximum negative and 1.0 is maximum positive modulation.

b_sh

Sets the sample-and-hold frequency of Oscillator B. Only very high values will activate the

effect and the higher the value, the lower the sample-and-hold frequency.

fm_amt

Controls the frequency modulation amount of Oscillator A by Oscillator B. The setting is bi-

polar with 0.5 meaning no frequency modulation.

fm_mod

Changes how the Envelope affects the frequency modulation amount. At 0.5 it has no effect

on the fm amount. Lower values increase the fm amount as the modulation envelope in-

creases and higher values do the opposite.

sub_am

Adjusts the Sub-Oscillator mix. The Sub-Oscillator Amplitude modulates Oscillator B with a

pitch that is one octave lower.

balance

Changes the mix-balance between Oscillator A and B. At 0.0 you will only hear Oscillator A

and at 1.0 only Oscillator B.

flt_freq

Controls the cut-off frequency of the parallel filters in relation to the frequency of Oscillator

flt_mod

Is bipolar and determines the cut-off modulation amount from the Envelope. 0.5 means no

modulation. 0.0 is maximum negative and 1.0 is maximum positive modulation.

flt_sep

Sets the separation amount between the cut-off frequencies of the two parallel filters. At 0.5

there is no separation and the filters act in unity as a single filter.

flt_q

Controls the "q value" (or "resonance") of the filters.

flt_kf

Determines how filter cut-off changes over the keyboard. Below 0.25 there will be no change

at all and the cut-off stays fixed. Above 0.75 the cut-off frequency will follow the keyboard

exactly.

fx_mix

Sets the initial dry / wet mix of the built in effect (a chorusing reverb). (The mix can be further

adjusted with the Effect slider on the main page.)

fx_len

Changes the length of the reverberation.

fx_damp

Controls how higher frequencies are dampened when the reverb decays. Higher settings

mean more dampening.

fx_chors

Adjusts the chorus amount. Higher settings introduce a chorus / unison effect to the sound.

fx_size

Changes the size of the perceived reverberation space. Note that this gene does not change

when growing branches because it would cause disruption of the audio.
