WHAT PROGRAM IS RECOMMENDABLE FOR CONVERTING MUSIC FILES?

I use dbPowerAmp for my bulk music conversion needs. I believe there's a Midi-In plugin for it too. The site is in your face about buying it though, you can download a trial with 21 days of full functionality and I think after that it still works except for MP3 Lame Encoder (which is trash anyways) and multicore support. I know I still use it and never bought it but that could be because I'm using an older version back when it was freeware.

Another alternative is Audacity. It can open a digital music file and convert it into other formats such as OGG. However you will need to convert the MIDI into a digital format like WAV. I use Winamp when I need to convert MIDI (or other weird formats that Winamp can play, like SPC) into something else as a middleman. You can tell it to use the Disk Writer plugin (under Preferences->Output->Disk Writer) to make a WAV file out of whatever it is playing like a MIDI. Take that output WAV file, plug it into Audacity, and tell it to export an OGG file.

I'd definitely try m4uesviecr's site first though. It looks a lot easier than any of the processes I laid out.

There are a lot of free online sites that let you convert your beautiful midi music into oggs.

I use this one:

Beautiful Midi Converter Website

Also, it might helped that you convert your midi to an mp3 using some free mp3 converters that use soundfonts pre-programmed into the converter process.

I have a similar pro--
Whoa whoa, thanks for this<3!

Yaaaaay! I've been looking for a proper working online converter for a while now. I prefer online to offline because the programs usually have viruses.

I had a beautiful MIDI that VX Ace wouldn't even play, so converting it to .ogg did the trick.
