Here's a bunch of waveforms I discovered/found. I will be using "the 42 melody" (t*(42&t>>10)) as an example.
t = a sawtooth wave
Disclaimer: some of these audios are loud.

Add this into your bytebeat expression: x=t=>(y), where x can be anything (presumably any 1 letter) and y is the waveform you want. The parenthesis are necessary only if the function won't work without them.
You can then use them like this: x(y) where x is the function name you used and y is anything (presumably a sawtooth wave)
Triangle wave example: trng=t=>(t<<1)^-(t>>7&1),
