Wrong Tempo and (sometimes) wrong instruments. Please help!

[Aeliffa]

I believe the server I'm playing on currently uses this script and I've had a few issues with it. The most glaring is that I can have a song at 200 BPM, that 4+ midi players all recognize as 200 BPM, but in game it will become 120 BPM. Since there's no way to alter the BPM in game (that I know of), it means a lot of songs end up sounding either too slow or too fast, completely ruining them.

I'm sure it's a problem with the midi player, but I should also note that there are some (but very few) songs that play at the correct tempo well above 120 BPM. I'm at a loss here, but it's made using this system very troubling.

The second and less prevalent issue is that sometimes when editing a midi to change the instrument, let's say from a piano to a guitar for example, it will not always work, and we'll end up with a glockenspiel or some other ridiculous instrument instead. The tempo is the number 1 problem here, but this is also a problem.

Any help would be greatly appreciated!
