New DSP models for VCV VCO and VCF

The VCV VCO and VCV VCF modules are over 8 years old now, so I decided to rewrite their DSP engines. They’ve received massive quality enhancements without significant changes to their behavior, for backwards compatibility. See the full details in their changelog.

Feel free to build them from source and try them before they are released, and let me know what you think.

What about the wavetable vco or the lfo modules? Or are those not in need of an update internally?

Awesome! Nicely done.

Nice!

Does the VCO still sync on the falling edge of a unipolar trigger? For a bipolar trigger it fires on the rising edge. It would be nice if it triggered on the rising edge of both unipolar and bipolar triggers.

For the Venom VCOs I default to a Schmitt Trigger going high at 2V and resetting at 0.2V, which works well with both unipolar and bipolar triggers. I have an option for the Schmitt trigger to go high at 0V and reset at -2V, which only works well with bipolar triggers, but sometimes is desired for proper phase alignment.
