Symphonium should work on linux and mac but for now only the windows version is available as an executable.
Users on other platforms should compile it from its sources.
I’d appreciate some help from other devs to make it easier for all user to use Symphonium.
For windows users : Download Symphonium.
Please note that you will find some MIDIFiles in the MIDILibrary folder of the downloaded rar file to get started !
