    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

The n function is used to generate notes on a chromatic (12 note) scale, 0 is middle C.
u/KilledByAPixel

It also displays how many half steps each note is from middle C and the frequency in hz

♫ Dwitter Oscillator Music Player ♪ (DOMP) is now loaded! This dweet does not play music itself but allows other dweets to play music easier. See comments for more info.

Show more comments…
u/KilledByAPixel

How to use: Put eval(localStorage.m) before your code to load DOMP. f=oscillator frequency, i=incremented each frame when playing, n:convert note to frequency, Z:2e3, z:-2e3
u/KilledByAPixel

The goal of this project is to allow for longer more complex music programs while also improving the ui and minimizing the annoyances.
