The Mother–32’s primary sound source is a single oscillator that produces two waveforms, sawtooth and pulse, the latter with variable pulse width and PWM. Only one of the waveforms is available at any given time without the use of patch cables, but both can be obtained simultaneously via the patchbay. You can modulate either the VCO’s frequency or its pulse width using the internal LFO or contour generator but, again, you can affect both simultaneously by patching external sources to any of its three pitch CV inputs in the patchbay. Portamento is also available. A second sound source is provided in the form of an analogue white-noise generator, and you can mix the output from this with the output from the oscillator using the pre–patched voltage–controlled mixer. Alternatively, you can inject an external signal (or, for that matter, another internal one) at the external signal input, whereupon the noise source will be disconnected and the mix will be between the oscillator and the additional source.
