I know FT 3.0 had one, but it was bad (which is probably why it got removed). I would like it to be worked on again though, seems like a good idea.

^Only site I know that has the songs. /.-./
So far, I only have BIT98 and BIT18 done, but I plan to try and get all of them done.
BIT98 Also has some note problems, as well as all of it not having much volume control. >.>

^Makes sense

The wave setting in the edit instrument window, or to use VXX and Speed 1.
Honestly, though, I dunno if it can switch waves fast enough to do what your attempting. /.-./

I like the tune, but I think it's a bit too fast for a menu theme, or maybe that's just me. \.o./

I didn't stop

Otherwise, the music that plays during the space-background levels.
You guys ever played Neverball? It's pretty fun \.o./
The cover itself is pretty accurate imo except for the very last part where I tried putting two parts into one square channel. The result is...OK. :l

I still don't know #4. I don't play many shmups \.-./
BUT
#3 is this, somewhat : https://www.youtube.com/watch?v=oROQFlmMhIU

This is pretty awesome! : D
Some of the songs do sound familiar, but the only two I found are :
#10 Sounds like this : https://www.youtube.com/watch?v=GzmqMlsM7wk
Frames 02 and 04 in #11 are basically this : https://www.youtube.com/watch?v=LbSLiNla5ik (to me at least)

I like this song! I think it would work for an ending theme for a game.
I hope it gets actually put into a cello/violin cover now that your mentioning it. /.o./
