Week 2

Colaborative live coding audiovisual environment for WebchucK

For this week the ChucK team is having a hackathon that will (I hope) help me do some improvements on other tools and helper classes that I need.

Week 3

Full integration of Xml reader and Parser into ChucK core

Xml is a fully functional class inside chuck-code that allow the user to load a musicXML file (exported from any graphical notation software) and play it using a UGen from ChucK. This will be the way to control the whole performance (Notated part).

Xml xml;

xml.open(me.dir() + "Daisy.xml");

xml.pushTag("score-partwise",0);
xml.pushTag("part",0);

xml.getNumTags("measure") => int measures;

string musicXML[0][0];

for(int i; i < measures; i++){

xml.pushTag("measure",i);
xml.getNumTags("note") => int notes;

for(int j; j < notes; j++){
xml.pushTag("note",j);
xml.getIntValue("duration",0,0) => int duration;
xml.getIntValue("pitch:octave",0,0) => int octave;
xml.getStringValue("pitch:step","R",0) => string step;
xml.getIntValue("pitch:alter",0,0) => int alter;
xml.popTag();
[step, Std.itoa(alter), Std.itoa(octave), Std.itoa(duration)] @=> string temp[];
musicXML << temp;
}
xml.popTag();
}

Week 4

Database connected and working - the logic not yet

I integrated the Firebase database to the webchuckIDE and it is working but there is a lot of issues that I need to solve in the logic side and also in the GUI side. because putting a lot of performers together in the same window has a lot complications. My plan is to start with 2 performers and try to integrate both codes.

Week 5

Database connected and working - the logic works

1. Xml already parses single voice scores but now also multiple voices at a time. The API can access tags and attributes, both with all ChucK types: int, float and strings.

2. The logic for the collab now works in real time so, my next step is to integrate webChuck in a to editor setup.

Week 6

Fully integration of DB and webchuck

This week was very exciting because the functionality worked great and now both, real time Database and webchuck are working and executing simultaneously in at least 100 devices.
I made some tests with a smaller scale setup (about 15 devices) and it was great to listen to 15 devices executing the same code and changing at the same time (not syncronized) by just connecting into a web page.
