Ranked 2nd at Revision 2023 Executable Music Compo

~~~~~~~~~~~~~~
| How to run |
~~~~~~~~~~~~~~

The executable has been built on a Raspberry Pi 400 using Raspberry Pi
OS (Bullseye), but it should also run fine on a Raspberry Pi 4. It may
also run on a number of other Pis without recompilation, but I haven't
tested this, so no promises.

To hear some music, you'll first need to take ownership of the file. If
you try to run immediately after downloading, you'll get a permission
error. To solve this, run '$ chmod 777 sine-time' in the terminal, then
you can enter '$ ./sine-time' to listen to some cool tunes. It'll also
build a WAV file (because listening to music through the terminal isn't
ideal).

| About the Engine |
~~~~~~~~~~~~~~~~~~~~

It uses a custom-built executable wavetable synthesizer program, which
you can find the source code for here:
https://github.com/protodomemusic/super-wavexe

The song itself is stereo, 44.1kHz, and uses 7 oscillator voices and 1
drum channel. The wavetables are generated at runtime, as are the drum
sounds, which use a single oscillator and a simple LFSR for noise.

Sequencing is in MML, but a custom one that really needs some serious
attention after a few years of 'it's good enough'. Source code here:
https://github.com/protodomemusic/mmml

Honestly, it's very upsetting to write in.

Effects include:
- Low-pass/high-pass filters
- Reverb
- Delay
- Distortion
- Waveshaping
- Wave blending?? Is that what it's called?

Huge thanks to all of the (numerous) sources I used when studying up on
DSP programming techniques (credited in the code) and Revision for
organising such a fantastic event.

I hope you enjoy the music!
