A modular synth written in pico-8

• design, code: waporwave
• code, optimizations: pancelor

how to use

Make sure to read the docs (WWM DOCUMENTATION.txt)

To get compiled or html builds, download from https://waporwave.itch.io/wwmodular.

If you want to run it locally, open PICO-8 and run 'wwmodular.p8'; it has include statements that combine all the .lua files.

modding

To add a module:

• go to modules.lua, and write a new function (see existing ones for example)
• add your new module function to the three lists at the bottom

PICO-8 PCM audio

If you want to write your own PICO-8 audio experiments, here some example code:

-- the amount of values to be written to the audio buffer.
-- stat(108) gets the number currently buffered, so 1536 lowers if there is too many being buffered.
-- A minimum is set to make up for any dropped frames later on.
local len=min(94,1536-stat(108))

-- for each value in the buffer, write a value (for example you might write the value of a sin() of an increasing step).
for i=0,len-1 do
  a = 128 -- 0-255 value, this should be silent write now since we're writing a constant value.
  poke(0x4300+i,a) -- write these values in memory
end
-- write 'len' number bytes from 0x4300 to 0x808 (the audio buffer)
serial(0x808,0x4300,len)

This is just one very minimal example of writing audio, you can most likely get help from the PICO-8 discord server or forums.
