SyncSawSynth is a synthesizer equipped with up to 10th order PTR sawtooth oscillator.

PTR stands for polynomial transition regions which is an aliasing suppressing technique. As the name suggests, this one hard syncs:

• Equipped with 2 of 0 to 10th order PTR sawtooth oscillator.
• Can also use sin. However, hard sync for sin is not alias suppressed.
• 3 types of hard sync option. Only use "Ratio" option for tonal sound.
• Phase controls. Possible to make a square wave with phase inversion.
• Frequency modulation between 2 oscillators. You can be a noise musician in a second.
• 1 AD envelope, 1 sin LFO and 1 pink noise generator for frequency modulation. The AD envelope uses equation (t^a * exp(-b * t)).
• Exponential ADSR envelope saturated with tanh for output gain.
• Equipped a filter that is serially connected 4 RBJ biquad with feedback. Low-pass, high-pass, band-pass, notch can be used.
• 4 types of filter feedback saturation.
• Linear ADSR envelope for filter cutoff and resonance. The output of filter envelope is logarithmically mapped to cutoff frequency.
• Key follow for filter cutoff and resonance.
