Muster A3

Muster A3 is an advanced pattern generator.

Muster A3 is the flagship pattern generator module and part of the paid Muster package. One can leverage up to 3 different sinus LFOs to create a gate and pitch signal pattern.

The gate signal is generated by LFO 1 and LFO 2. The selected speeds of the LFOs create a repeating gate signal (0 Volt is Gate off, +10 Volt is Gate on).

The pitch signal is based on LFO 3 and its speed settings. The pitch signal is limited to ±10 Volt.

The signal of each LFO can be additionally modified and modulated using the Scale and Offset parameters.

Notes

  • Additional Muster A3 signals can be accessed using the Muster Ax expander.

ParameterDescription
GATE (port)Output port: Gate signal based on LFO 1 and LFO 2. The signal can be modified using the corresponding Scale and Offset knobs.
PITCH (port)Output port: Pitch signal based on LFO 3. The signal can be modified using the corresponding Scale and Offset knobs.

The resulting signal is calculated using the following formula
output = (input * Scale) + Offset.
LFO-L - FrequencyFrequency of the Lead LFO. All other LFO frequencies are based on this leading frequency.
LFO-L - Frequency (port)Input port: the modulation signal. It can be any signal in the range of ±10.0 volts.
LFO-L - Frequency (mod)The modulation amount can be adjusted in the range of ±100.0%. When set to any negative value, the modulation signal will be inverted.
RunStart/Stop to output the GATE and PITCH signal.
Run (port)Input port: Any signal other than 0.0 volt will let the sequencer run. If the signal drops back to 0.0 volt, the sequencer stops and resets the phases of LFO 1/2/3 and the Lead LFO.
Reset (port)Input port: Reset the phase of LFO 1/2/3 to 0. The Lead LFO will continue to operate.
LFO-1/2/3 - MultiplierThe multiplier is the ratio between the Lead LFO frequency and the LFO 1/2/3 frequency. The multiplier can be entered in the range of 1-10. Where 1 is the same frequency as the Lead LFO frequency and 10 is ten times the frequency.
LFO-1/2/3 - Multiplier (port)Input port: the modulation signal
LFO-1/2/3 - Multiplier (mod)The modulation amount can be adjusted in the range of ±100.0%. When set to any negative value, the modulation signal will be inverted.
LFO-1/2/3 - ScaleScales the LFO 1/2/3 signal. Scale can be entered in the range of ±1. Where -1 is the inverted signal, 0 is no signal, and +1 is the original pitch signal.
LFO-1/2/3 - Scale (port)Input port: the modulation signal
LFO-1/2/3 - Scale (mod)The modulation amount can be adjusted in the range of ±100.0%. When set to any negative value, the modulation signal will be inverted.
LFO-1/2/3 - OffsetOffset is a DC offset of the LFO 1/2/3 signal. It can be entered in the range of ±1, which equals ±2.5 volts.
LFO-1/2/3 - Offset (port)Input port: the modulation signal
LFO-1/2/3 - Offset (mod)The modulation amount can be adjusted in the range of ±100.0%. When set to any negative value, the modulation signal will be inverted.
Gate LevelGate Level influences when the Gate is open or closed. By default, the Gate Level is 0.0 volts. It can be entered in the range of ±1, which equals ±5.0 volts.
Gate Level (port)Input port: Signal to modulate the Gate Level.
Gate Level (mod)Modulation intensity of the input port signal. TODO
Gate Mode - Plus“Plus” combination mode of the LFO 1 and LFO 2 signal.

The Gate Modes can be combined in the following ways
Plus(off) and Mult(off): LFO 1
Plus(on) and Mult(off): LFO 1 + LFO 2
Plus(off) and Mult(on): LFO 1 * LFO 2
Plus(on) and Mult(on): (LFO 1 + LFO 2) * (LFO 1 * LFO 2)
Gate Mode - Mult“Multiplication” combination mode of the LFO 1 and LFO 2 signal.
Gate Mode (port)When the Gate Mode is modulated by a signal, the Gate Mode is toggled between Plus(on) and Mult(on). A signal <= 0.0 volts will activate the “Plus” mode, else “Mult” mode is activated.
