OSCILLATORS (Continued)
LIN FM IN (Linear Frequency Modulation)
Connecting an audio signal or high-frequency control signal to this input
introduces Linear Frequency Modulation (FM) to a patched oscillator, which
can be useful in creating brash, metallic, or bell-like tones.
CV INPUT: -5V to +5V Control Voltage (AC coupled)
PWM IN
A control signal connected to this input will modulate the pulse width of the
Square or Narrow Pulse waveform selected by a patched oscillator. Pulse Width
Modulation (PWM) varies the duty cycle, or pulse width of a wave, and thereby
changes its harmonic content. Among other things, PWM is often used to mimic
the sound of ensemble strings and to thicken bass sounds.
CV INPUT: -5V to +5V
WAVE OUT
The audio signal available at this output is determined by the settings of the
OCTAVE, FREQUENCY, SYNC and WAVEFORM knobs of a patched oscillator.
CV / AUDIO OUTPUT: 10V peak-to-peak
The Mixer is where all of the sound sources within Matriarch are blended
together before being passed on to the Filter. Patch points in the Mixer
allow each hardwired source (Oscillators 1 – 4 and Noise) to be replaced
with an external audio signal. There is also a line-level Instrument Input on
Matriarch’s rear panel that feeds directly to the Mixer.
MODULE PROVENANCE: Matriarch’s Mixer is based on the classic
Moog CP3 module.
