Herbs and Stones MOUSSE

Clock section:

The clock section is the main heartbeat of Mousse and it controls the timing of the sequencers.

Controls:

• "c i" jack input: external clock input, 0-5V
• "c o" jack output: active clock output (internal or external)
• "c rate" knob: controls the rate of the internal clock
• cv" trimmer knob and CV input: CV input to modulate the internal clock (think tempo changes, wobbly rhythmic patterns)

LFO X:

LFO X is tied to LFO Y (more on that later) and is controlled via the "skip" button and LFO Y "steps" knob and CV input.

LFO X outputs a random waveform that can be tamed in various ways.

Controls:

• "skip" button: enabled at start, when pressed it toggles between two amplitude ranges for the waveform. One is full range and in the other the range is dynamically modulated by LFO Y.
• "steps" knob and CV input (in common with LFO Y): controls the resolution of the digital random waveform: in full counterclockwise position you get white noise, gradually turning the knob clockwise you can hear more and more "steps" (useful to generate random swinging melodies).

LFO Y:

LFO Y is a variable waveform LFO that similarly to LFO X can also become a generative pattern sequencer.

Controls:

• "rate" knob and CV input: controls the speed of the LFO
• "shape" knob and CV input: when in full CCW position outputs a rising sawtooth wave, turning the knob clockwise the sawtooth morphs into a sine/saw hybrid
• "steps" knob and CV input: controls the resolution of the digital random waveform: in full counterclockwise position you get a "pure" LFO waveform, gradually turning the knob clockwise you can hear steps that gradually will become a stepped pattern (useful to generate non random looping swinging melodies).
• "r" gate input: the reset input, when it receives a gate the waveform resets at its zero point

Envelope generators:

Two identical decay-only envelope generators which can be inverted with the dedicated gate input.
(Think sequencer control over rising and falling curve of the envelope)

Controls:

• "g" input: trigger or gate input to excite the envelope generator
• "decay" knob: controls the length of the envelope generator
• "i" gate input: when a high gate signal is patched into this input the envelope gets inverted (thus creating a rising envelope voltage)
• "eg a" output: output for envelope generator a
• "eg b" output: output for envelope generator b

Sequencers A and B:

The two sequencers work independently but share the same clock and some of the features.

Sequencer A Controls:

• - "slew" knob: controls the slew limiter for the stepped sequence that is created by turning the four pitch knobs.
• "g" slew gate input: if a gate signal is patched into this input the slew limited signal is availabla only when a high gate is present at the input.
• "steps out": outputs a four level voltage sequence (controlled by the four knobs on the left) that can be used to control various parameters of the synth
• "a1"..."a4" gate outputs: the four gate outputs of the sequencer
• "rotate" button and gate input: when the button is pressed or a gate is patched into the input, sequencer A changes rotation
• "steps" button and gate input: when the button is pressed or a gate is patched into the input, sequencer A changes length: two steps, three steps, four steps

Sequencer B Controls:

• - "div" button: when it is pressed it toggles between a two step pattern (gates 1 and 3 or gates 2 and 4, depending on which step is active when the button is pressed) and a normal four step pattern
• "form": when pressed it toggles between normal mode and semi random mode for sequencer B
• "b1"..."b4" gate outputs: the four gate outputs for sequencer B
• "rotate" button and gate input: when the button is pressed or a gate is patched into the input, sequencer B changes rotation
• "steps" button and gate input: when the button is pressed or a gate is patched into the input, sequencer B changes length. two steps, three steps, four steps

Voice A:

A "time manipulation synthesis" voice. A sine wave is fed through an audio rate chorus effect to generate 2 OP FM-like sounds.

Controls:

• "pitch" knob and CV input: pitch of the sine wave oscillator
• "mod" knob and CV input: rate of the chorus modulation effect
• "amount" knob and CV input: depth of the chorus effect
• "fb" knob and CV input: feedback of the modulated delay which generates the chorusing effect
• "vca" knob and CV input: control for voice A analog VCA
• "cutoff" knob and CV input: control for voica A analog VCF center frequency
• "resonance" knob: control for voice A analog VCF resonance
• "mode" button: toggles between filter A modes (low pass, band pass, high pass)

Voice B:

Voice B is a subtractive multi waveform voice

Controls:

• "pitch" knob and CV input: pitch of voice B digital oscillator
• "wave" knob and CV input: blends in a not linear way between three waveform outputs: triangle, square and sawtooth
• "noise" knob and CV input: noise blend stage, the waveform / noise ratio changes organically depending on the waveform control position
• "vca" knob and CV input: control for voice B analog VCA
• "cutoff" knob and CV input: control for voice B analog VCF center frequency
• "resonance" knob: control for voice B analog VCF resonance
• "mode" button: toggles between filter B modes (low pass, band pass, high pass)
