The WASP is a 3-oscillator synth with 2 LFO's and 2 ADSR envelopes, a ringmodulator, FM, PWM and a distortion unit.

## Filter Parameters

The Filter section is located at the top left.

#### Cutoff ("CUT")

Adjusts the Filter cutoff frequency. The keyboard track ("KB TRACK") button makes the cutoff frequency dependent on the actual note played - higher notes mean higher cutoff, lower notes means lower cutoff.

#### Resonance ("RES")

Adjusts the Filter resonance.

#### Envelope Amount ("ENV")

The amount the filter cutoff frequency is affected by the Filter ADSR.

#### Filter Type

The 6 green buttons select the filter type. LP[fat] = 24 dB Lowpass Filter, LP+NOTCH = 12 dB Lowpass + Notch Cascade, DBL NOTCH = double notch filter, BP = 24 dB Bandpass Filter, HP = 24dB Highpass Filter.

## Oscillator section

The oscillator section is located at the middle of the top. The first 2 wheels, CRS and FINE, are the coarse and finetuning of oscillator 1. Coarse tuning is adjustable in the range -3/+3 octaves, finetuning in -1/+1 semitone. The green buttons below set the oscillator shape, which is sawtooth by default. Oscillator 2 has the same controls as 1 right next to it. The slider "<>" between OSC1 and OSC2 adjust the mix ratio of the oscillators. When it's slid fully towards OSC1, oscillator 2 won't be audible.

Oscillator 3 plays 1 octave below oscillator 1. The AMT (Amount) wheel sets it's volume, which is zero (inaudible) by default. Osc 3 has only 2 shapes, sawtooth (default) or square.

The RING MOD button at the right of the oscillator section modulates Oscillator 1+2. This often leads to a harsh metallic sound, dependent on the shapes and frequencies of both oscillators.

The PW (Pulse Width) button only has effect when at least one of the oscillators is set to the square shape (the 2nd shape). It shortens 1 of the square flanks, thus making the sound thinner. At the very left position (default) it has no effect.

The FM (Frequency Modulation) button modulates the frequency of oscillator 2 with the output of oscillator 1. To hear the effect, set the osc mix slider (<>) to the right (OSC2). Classic FM uses sinewaves (the 3rd oscillator shape), other waveforms may give noisy or strange results.

## LFO-1

LFO-1 can modulate the pitch of the output ("OSC1+2"), the filter cutoff frequency ("FILTER") or the Pulse Width ("PW"). The SYNC button synchronizes the frequency of the LFO to a multiple of the current tempo. RESET sets the LFO to the beginning of the LFO waveform (Phase=0) when a note is triggered. Above the AMT and SPD wheels, the LFO waveform can be set (default is a sinewave).

## LFO-2

LFO-2 can modulate the pitch of Oscillator 1 ("OSC1"), the mixing ratio of oscillator 1 & oscillator 2 ("OSC MIX") and finally the amplitude of the whole output ("AMP"). SYNC+RESET work as described above.

## Amplitude ADSR

See ADSR. The link button on top links the Amplitude & Filter section for editing convienence. When LINK is pressed and the amplitude ADSR wheels are moved, the corresponding Filter ADSR wheel will move too.

## Filter ADSR

The envelope for the Filter cutoff frequency.

## Distortion Parameters

#### DIST

The green button turns the distortion unit on/off.

#### Drive ("DRV")

Adjusts the drive. More drive means heavier distortion.

#### Tone ("TONE")

Changes the color of the distortion. Turned to the left, the sound gets muddy, turned to the right, more bright.
