Virtual Analog Oscillator Hard
Synchronisation: Fourier Series and an Efficient Implementation.

This paper investigates a number of digital methods to
produce the Analog subtractive synthesis effect of ‘Hard
Synchronisation.’ While the original effect is produced by
an explicit waveform phase reset, other approaches are
given that produce an equivalent output. In particular,
based on measurements taken from a real-analog synthesizer,
a comb filtering model is proposed. This description
ties in with earlier work but here an explicit structure is
provided. This filter-based approach is then shown to be
far more computationally efficient than the synchronisation
by phase reset. This efficiency is at a minor cost as it is
shown that it has a minimal impact on the sonic accuracy.
