Description

zb.subtractive is a subtractive synthesiser, which utilises 2 cross-fadable oscillators and a state-variable filter. It also features breakpoint envelopes, which can be used to automate the amplitude and filter parameters.

The duration parameter sets the global length of the breakpoint envelopes in ms.

The harmonics dial crossfades between a sine and square wave oscillator. The higher the value of the parameter is, the more harmonically rich the sound.

The leftmost breakpoint envelope controls the amplitude value over time.

The middle breakpoint envelope controls the cutoff frequency of the filter over time.

The rightmost breakpoint envelope controls the steepness (resonance) of the filter.

The LP HP ^ V tab switches the type of the state variable filter between low-pass, high-pass, band-pass and notch.

The range parameter controls the size of the range of the cutoff frequency sweep breakpoint envelope.

The offset parameter shifts the position of the above range.
