Modul-8 allows you to create music in PICO-8 with three channels of 2OP PM synthesis.

Features

With a look based on PICO-8's built-in tracker, Modul-8 was created to be as simple as possible to not only save CPU space but also make it more accessible when it comes to inputs. The tracker uses both standard PICO-8 buttons and mouse input; while the arrow keys are used to move across the grid and the O/X butons (Z/X keys) are used to cycle through notes, the mouse is used to control the instrument and playback options. While the PM synthesis Modul-8 uses is very basic, it still allows you to craft some interesting sounds by controling the volume, ADSR and frequency multiplication of both operators. Tunes created with the tracker are always looped, but the overall lenght of the track and the loop point of each pattern are adjustable.

File Format

Despite the confusing nature of Modul-8's text-based file format, tunes can be saved very easily. Pressing ctrl+c after saving is needed on the BBS and pressing ctrl+v beforehand is mandatory if you want to load a track. To keep your saved files, you'll just have to paste them in a word processor, or you could even share them here! For anyone who's curious, the format contains the values for the tune's format header, speed, size, loops, instrument variables and note sequence (including instrument changes) in that order.

Demo

To demonstrate Modul-8's capabilities, here's a six pattern long demo loop:

Thanks to Bikibird and Luchak for helping with and providing code for PCM playback in the PICO-8 server! (also used in Moonshine's PICO-Patch)
Special thanks to other members of MoonShine and the PICO-8 server!

> At least at the moment, for some weird reason, Modul-8 seems to suffer a lot of lag on both the BBS and PICO-8 Education Edition.

I've always had issues with PCM audio in PICO-8 carts on the web, never been able to fix it.

@luchak It does work on the web now, though.

here's a song I made:
