• Allow importing Sf2, Sf3, Sfz, or raw audio (WAV, OGG, MP3, etc.) formats for instrument creation
• Import good quality SoundFonts from https://sites.google.com/site/soundfonts4u/
• See what other effects can be added from https://github.com/jonathanneels/Audio-Input-Effects and from https://alemangui.github.io/pizzicato/
• Make library fully General MIDI 2 compliant
