So NES VST is a free vst built to mimic the how sounds in an Nintendo Entertainment System(NES) work. The NES had three synth channels, one noise channel and one DPCM(or sample) channel. The three synth channels generously offered two pulse-waves and one triangle wave. The pulse waves could be configured as 6% 12% 25% 50% or 75% pulses where 50% would be the closest to a normal squarewave. A smaller percentage means a thinner sound. You can also have a pitch, fine-pitch and volume envelope to create different characters of sound just like a normal oscillator synthesizer.
The triangle wave was presented "as is" and could only be modified in pitch and volume.
What I wanted to be able to do was create versatile sounds with qualities like... String-like, plucky, growling, singing, flute-like, etc. To do that all I had to realize was that the colorful boxes were just simple "step"-envelopes that work just like a normal ADSR. There's a generous tempo option with a minimum of 16ms between steps(when you turn tempo sync off, otherwise it goes in increments of note-values).
Drawing sinewave-like shapes in the fine pitch window will give you a vibrato which can also loop from a different point than the starting point(that's the thin colored line in the top of the window). So you can have a note that begins to oscillate in pitch after a certain number of steps. Which is desirable for a "singing" type vibrato.
Strings can be made quite easily with a stair-like volume envelope. The more LFO Steps and the shorter the Step Time, the smoother the attack.
In conclusion, this plugin is extremely versatile and useful if you want to have 8bit sounding synths anywhere.
