OSC with internal SYNC and much more
The heart of this oscillator is an internal wavefolder that does pretty the same like two sync'd oscillators with an frequency ratio from 1:1 to 1:8. It's very CPU friendly and antialiasing. Different to NI's core and primary library Sync OSC's it folds for the sawtooth wave around zero and produces therefore no DC. Different to NI's core and primary library Sync OSC's it folds for the square wave also completely different, produces no DC and has softer transitions.
The oscillator produces a sawtooth and a square waveform, has pulsewidth (square) and phaseshift (sawtooth), you can fade between both waveforms, it has a second voice to detune and many modulation options.
However, it's a light version of an oscillator I will use for my next synth and it does not like fast modulation.
