Sharktooth waves are the wonderful, yet often missed, waveform which finds a great balance between saws and sines. This is the sharkfin oscillator which mutates and warps those teeth, for a more expansive sound set.

Just turn the black dial to reshape the “fin” and/or flip the switch underneath for four different sets of fin types. A separate oscillator at the bottom can be summed to put a point on the fin (or chip at it), or it can be toggled into a sine oscillator with relative tuning.

It’s all pretty simple, yet fills a gap between the classic waveforms, while a single dial/switch pair lets you recalibrate the internal circuit for a variety of sounds that branch away from the typical sharktooth oscillator.
