Open Source C MIDI Software for ChromeOS

PortMedia was created to develop and share cross-platform, open-source I/O libraries for digital media including MIDI, video, and audio. Only a few things were released under the PortMedia umbrella. These are now hosted by the github.com/Portmidi/ project, where you can find the lastest versions of PortMidi, portsmf (Standard MIDI File support and more), and see github.com/rbdannenberg/scorealign for MIDI and/or Audio score alignment.

Thank you for your interest in Speedy Composer. Speedy Composer is an automated application for composing melodies for Speedy Net members. We recently made changes to the source code of Speedy Net, and converted it into the Python language and Django framework. Since Speedy Composer was originally written in PHP, it is not adapted to work with Speedy Net in its current form. So unfortunately we were forced to temporarily close the app Speedy Composer. But don't worry, we kept backups of all the tunes composed by Speedy Composer, and when the website is reopened we will upload them to the new site. Speedy Composer and Speedy Net are open source applications, free software. We are currently looking for volunteers to help us convert Speedy Composer to Python. If you are interested in volunteering, please contact me by email. Thank you and good luck, Uri Rodberg Founder and Director of Speedy Net and Speedy Composer, Speedy Paz Technologies Ltd. uri@speedy.net
