MIDI Synth/Sequencer
 

it seems like Graal has always been lacking from a music standpoint and I believe a MIDI Synthesizer and Sequencer could be taken advantage of if implemented into Graal and usable by GScript

The obvious examples I can think of is Musical Instrument NPCs in game and the creation of a basic track that can have instruments added/removed based on what's happening around you (Twilight Princess made good use of such a feature by adding to music if you were fighting, riding a horse, etc)

I also know there is quite a bit of MIDI Composing software available but these tools are expensive and could be a stumbling block to servers creating original music for use in game.

Been asked for sooooo much :(

Hell Raven made something in pure gscript that did this once. It wouldn't be too difficult to script, if one had the patience to sample an instrument properly and upload the individual sounds.
