The ways and means to make a copy of everything that's been uploaded to http://axechange.fractalaudio.com/
This probably isn't totally kosher but I worry this archive of settings will go away some day.
There's a downloader in the ./bin/ directory that will pull down new things since it was last run. It keeps an index that was last seen in the config.yaml file in the root of the repository. If you remove it, it downloads things from the very first preset again.
To run the downloader:
gem install bundler
bundle install
bundle exec bin/axechange_downloader
No command line options or anything. It's pretty basic. It expects curl to be available on the PATH as it uses that for the actual download of the SysEx data files. The downloaded presets and cab files end up in a ./preset and ./cab directory respectively.
The presets are the work of their respective authors. They are downloaded under the ToS of Axe-Change.
