xmlplay

xmlplay is a javascript program that renders a score file (MusicXML or ABC) and plays the music using real time synthesis in the browser. For each musical voice it displays a cursor in the score that highlightes notes as they are played.

All software is javascript running in the browser.

Features:

• The score is rendered as SVG (Scalable Vector Graphics) with abc2svg
• Reads ABC or MusicXML (on the fly translated to ABC with xml2abc-js)
• Plays the music with real time synthesis in the browser.
• Can also play the music with pre-rendered wave forms.

Real time synthesis

xmlplay implements a synthesizer using soundfonts in real time. Every played note is synthesized from a sample, applying volume envelope, modultated filter, vibrato and tremolo as needed.
Technically speaking xmlplay implements a synthesizer for SF2 soundfonts.
• Geneva Old Style with real time sf2 synthesis in the browser
• Prelude BWV 539 with real time sf2 synthesis in the browser
• Palace of Twelve Phases, fragment from The House at Windy Corner
• Marching Drum Cadences (from https://musescore.com/krazsk2/cadences)
• xmlplay.html Try out your own score.

Pre-rendered single notes

xmlplay can also play the music with pre-rendered wave forms.
For every single note a 3 second wave form has been recorded off-line (using FluidSynth) as a short mp3 file.
Playback now does not synthesize at all but just plays these 3 second mp3's for every sounding note. (known as midi-js, see here and here)
You can compare the resulting sound with the real time synthesis above.
• Geneva Old Style no synthesis but large pre-rendered waveforms
• Prelude BWV 539 no synthesis but large pre-rendered waveforms

Embedded ABC

xmlplay_emb is a version of xmlplay that renders ABC notation embedded in an HTML document. The embedded ABC is turned into score pictures that allow playback. Clicking inside a score picture starts playback, clicking outside the score stops playback. Clicking inside a playing score picture repositions playback.

Dropbox demo:

xmlplay can load files directly from dropbox, using as special file name in the URL with the following format: "d:15-digit-ID/filename.xml". The 15-digit-ID is taken from the link that you can make in Dropbox to share a file with others. The following link is an example:

• xmlplay.html?d:bdnds0wkou3tk9x/tango-D3.xml

The link Dropbox gave back for sharing this file was:
https://www.dropbox.com/s/bdnds0wkou3tk9x/tango-D3.xml?dl=0
The "15-digit-ID/filename.xml" you need for xmlplay starts after .../s/ until ?dl=0

VCF demo

xmlplay understands many parameters from the SoundFont-2 specification. The following example shows a modulated low pass filter that is swept from high to low across the audio spectrum. It also demonstrates vibrato with a slight simulaneous tremolo.
• Brass finale modulated filter, tremolo and vibrato (in real time with the Web Audio API of the browser)
