<p>In bitrhythm code is evaluated for every cycle.</p>
<p>1 beat = 60 / tempo
1 cycle = 1 beat / ticks</p>
<p>For every cycle visual and audio code is evaluated.</p>
<p>The edit checkbox allows you to perform long edits, where only old code is evaluated. Once you disable it, all the new edit changes are applied in the next cycle.</p>
................................................................................
<p>Sidechain compression is a simple algorithm which observes amplitude of another instrument but you can generalise it to anything. By attaching observers to time or other instruments you can create sections within the song that can trigger others with conditional logic. This is similar to pure data’s bangs - <a class="reference external" href="https://www.youtube.com/watch?v=nTTZZyD4xlE">see this</a>. In future this will be referred to as side events. You could decrease the volume of the drums to have the snares drop automatically for example.</p>
<p>This is something that you can’t do in DAWs.</p>

<p>In bitrhythm code is evaluated for every cycle.</p>
<p>1 beat = 60 / tempo
1 cycle = 1 beat / ticks</p>
<p>For every cycle visual and audio code is evaluated.</p>
<p>The edit checkbox allows you to perform long edits, where only old code is evaluated. Once you disable it, all the new edit changes are applied in the next cycle.</p>
................................................................................
<p>Sidechain compression is a simple algorithm which observes amplitude of another instrument but you can generalise it to anything. By attaching observers to time or other instruments you can create sections within the song that can trigger others with conditional logic. This is similar to pure data’s bangs - <a class="reference external" href="https://www.youtube.com/watch?v=nTTZZyD4xlE">see this</a>. In future this will be referred to as side events. You could decrease the volume of the drums to have the snares drop automatically for example.</p>
<p>This is something that you can’t do in DAWs.</p>

<p>You can use Bitrhythm for making music similar to the music possible with trackers like Buzz / Renoise / OpenMPT. I call this approach Hard Coding music. This is also known as executable music in the Demoscene.</p>
<p>You can also use Bitrhythm for Live Coding and Algorithmic composition.</p>

<p>I make <a class="reference external" href="https://xyzzyapps.link">web apps</a> for a living. I started messing with algorithmic composition using pure data around 2011. In many ways Pure Data was my first DAW. Although nothing much came out of it musically, it transformed the way I view programming. The unix pipes concept is identical to the data flow model in pure data; albeit with more connections.</p>
<p>For my music I moved onto Electribe, Renoise, Reaper and live looping with my guitar. I started exploring sonic pi in 2019 but TBH none of the live coding tools were doing what I wanted - basically tweaking /knob-twisting in techno so I started my work on this project. <a class="reference external" href="https://www.youtube.com/watch?v=adz1Gv5Lm34">This library</a> in sonic pi comes close to what I am trying todo with this project. In bitrhythm time is divided into ticks like renoise tracker.</p>
<p>After my initial work on the project in 2019, the project got sidetracked. After seeing <a class="reference external" href="https://www.vitling.xyz/toys/acid-banger/">endless acid banger</a> I had an epiphany to work on this project again with programmatic knobs. I was able to compose an endless and interactive dubtechno demo track. In March 2021, I also picked up on literate programming so this document will have both code and documentation intertwined.</p>

You can also use Bitrhythm for Live Coding and Algorithmic composition.
## ADC 2021
I presented Bitrhythm in ADC '21 and the ICLC '21 for other audio developers.
[Slides ADC '21](https://xyzzyapps.link/ADC21.pdf)

## Inspiration for the project
I make [web apps](https://xyzzyapps.link) for a living. I started messing with algorithmic composition using pure data around 2011. In many ways Pure Data was my first DAW. Although nothing much came out of it musically, it transformed the way I view programming. The unix pipes concept is identical to the data flow model in pure data; albeit with more connections.
For my music I moved onto Electribe, Renoise, Reaper and live looping with my guitar. I started exploring sonic pi in 2019 but TBH none of the live coding tools were doing what I wanted - basically tweaking /knob-twisting in techno so I started my work on this project. [This library](https://www.youtube.com/watch?v=adz1Gv5Lm34) in sonic pi comes close to what I am trying todo with this project. In bitrhythm time is divided into ticks like renoise tracker.
After my initial work on the project in 2019, the project got sidetracked. After seeing [endless acid banger](https://www.vitling.xyz/toys/acid-banger/) I had an epiphany to work on this project again with programmatic knobs. I was able to compose an endless and interactive dubtechno demo track. In March 2021, I also picked up on literate programming so this document will have both code and documentation intertwined.
The documentation for the literate programming project - wheel is [available here](https://xyzzyapps.link/wheel/).
## Support this project
My goal is to make bitrhythm easy for both professionals and music learners. Support my work to get regular updates. Supporters will also get free accounts when I add pro features! Also get notified on latest developments and tutorials in the web audio world.

## Inspiration for the project
I make [web apps](https://xyzzyapps.link) for a living. I started messing with algorithmic composition using pure data around 2011. In many ways Pure Data was my first DAW. Although nothing much came out of it musically, it transformed the way I view programming. The unix pipes concept is identical to the data flow model in pure data; albeit with more connections.
For my music I moved onto Electribe, Renoise, Reaper and live looping with my guitar. I started exploring sonic pi in 2019 but TBH none of the live coding tools were doing what I wanted - basically tweaking /knob-twisting in techno so I started my work on this project. [This library](https://www.youtube.com/watch?v=adz1Gv5Lm34) in sonic pi comes close to what I am trying todo with this project. In bitrhythm time is divided into ticks like renoise tracker.
After my initial work on the project in 2019, the project got sidetracked. After seeing [endless acid banger](https://www.vitling.xyz/toys/acid-banger/) I had an epiphany to work on this project again with programmatic knobs. I was able to compose an endless and interactive dubtechno demo track. In March 2021, I also picked up on literate programming so this document will have both code and documentation intertwined.
The documentation for the literate programming project - wheel is [available here](https://xyzzyapps.link/wheel/).
## Support this project
My goal is to make bitrhythm easy for both professionals and music learners. Support my work to get regular updates. Supporters will also get free accounts when I add pro features! Also get notified on latest developments and tutorials in the web audio world.

You can also use Bitrhythm for Live Coding and Algorithmic composition. ## ADC 2021 I presented Bitrhythm in ADC '21 and the ICLC '21 for other audio developers.
