A 4-pole transistor ladder lowpass filter.

As you increase samplerate, you might have to increase block size also to make it not produce noise.

## Oxcart Oscillator
## Oxcart

It has a frequency knob and a CV in. Very simple.
Oscillator with a frequency knob and a CV in. Very simple.

Approx. +-5V output.

## Dirt

Just a very simple high-pass filter.

## Flopper

Takes the top part of the wave from input 1, and the lower part from input 2 to output 1.

Does the opposite for output 2. The knob and CV determines which level determines where to switch from top to bottom.

Not anti-aliased, so sometimes good idea to follow it with a low-pass.

## Goals

Low CPU usage.

It will never sound exactly like the real analog transistor ladder filter. But should sound nice and unique.

The graphics are placeholders as I am focusing on the sound for the time being.
