I quickly Googled it to see if it'd work after I saw Hydrogen being a Linux app, and apparently there are some sound issues, but nothing too crazy. Now that you mention that, I feel pretty inspired to create a post at some point about making your Pi into a music Pi, I keep seeing things here and there about people using it for variety of purposes so it could be nice to gather all that info up :) I will definitely check out Hydrogen, thank you!
