StringyFi

Convert MusicXML to PIC assembler for running on the Boldport Club 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'.

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

Add this line to your application's Gemfile:

gem 'stringyfi'

And then execute:

$ bundle

Or install it yourself as:

$ gem install stringyfi

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.
