pulsine2
modded waveform oscillator able to make saw, sine and pulse waveforms using the "gain" parameters -"gain1" controls the phase width going into the sine shaper, saturated. -"extend" enables the gain to go lower, enabling saw->sine->pulse morphing instead of only sine->pulse. -"gain2" controls the width of the sine going into a saturator. the pitch output outputs the combined pitch information (parameter+input+FM-signal), this can be used together with the "mostfilter" module to filter the waveform while keeping track of the modulated pitch in real time. -the result goes through a highpass filter to remove DC-offset
