Foxglove is a monosynth featuring a waveshaping section which can be modulated by the internal envelope generators and LFOs, or automated by a VST host. The left and right channels are generated independently – allowing for interesting stereo effects.
The sliders in the waveform generator section act as control points on a simple transform function which modifies the basic waveform, with slider III corresponding to the central zero-crossing point of the input signal. The ouput signal is filtered to reduce aliasing artifacts and DC offset issues.
The waveform is unaffected when the sliders are in the default position.
Moving the first and last sliders so they are aligned with the adjacent sliders results in the peaks of the waveform being clipped.
If the sliders are arranged in a V shape the input signal is rectified.
