We'll cover the basics of the Virtual Analog Filter (AKA a DSP Filter).
Part 1, covers the basics of the filter code.
This Video, Part 2, adds in a Envelope Generator and LFO modulation.

The math used to create the Filter is very complex and won't be covered in detail.
There is a free book by Vadim Zavalishin that does go into detail the math used to create the filter if you wish to try to understand it.
You can find a free copy of it at:

What these two videos will cover is where to find sections of the code that can be readily changed for custom needs.
This video is one of many in a series that educates how a DIY Virtual Analog Monosynth synthesizer, called the “BP Synth”, was programmed.
