For B.B.B.F.F., WeimTime007 did a version in C with a visualization (you can watch it after the jump) and a midi.
For This Day Aria, again, there's a visualization (after the jump) and midi.
For Love is in Bloom, WeimTime007 did two visualizations: one for the original version (after the jump), and one for the extended version (in the video to the right). There's also a midi of the original by whyPon and a midi and sheet music of the extended version by DJDelta0. Many thanks to all these people for sharing their great work!
