StringyFi
Convert MusicXML to PIC assembler for running on the Boldport Club Stringy.
About the Stringy
The Stringy is an open source hardware project from the wonderful Boldport Club.
The Stringy was Project #14 from June 2017, and is a remix of MadLab's 'Funky guitar'.
About StringyFi
StringyFi is a simple gem that converts MusicXML source files to a PIC assembler source format that can be compiled and programmed to the Stringy.
See LEAP#349 DemoBurner for a complete example of this in practice.
StringyFi has some serious limitations, some of which are in its implementation of MusicXML parsing, some are fundamental limitations of the Stringy. I have found that most scores need tweaking to be reproduced acceptably on the Stringy, and some are just too complex (without re-writing the Stringy firmware en-masse). Some key points to note:
- The String uses ony 2-bit (4 levels) of note duration, so the conversion squeezes the score into 4 note durations as best as possible
- many notation features ignored: slides, ties etc
Installation
Add this line to your application's Gemfile:
gem 'stringyfi'
And then execute:
$ bundle
Or install it yourself as:
$ gem install stringyfi
Usage
The StringyFi executable accepts a file path to the MusicXML source to convert, and emits the assembler source on STDOUT (so it can be redirected as appropriate).
For example:
$ stringyfi ./spec/fixtures/music_xml/chromatic.xml > ../CustomDemo.X/demo.tun
The spec/fixtures contains a few examples that are also used in tests.
