This isn't just because I want to help you. It's because I hate the MIDI sound with a burning passion.
Basically you just post a finished midi, describe how you want it to sound (any flangering you want added to an instrument, reverb, change all the instruments to techno, up the tempo, bass boost, etc.) and I turn it into a nice crispy MP3. I will not be doing re-writes. Just fonts.
Any takers? This sort of job gets done quickly, let me tell you.
Examples are attached. The first file is the original MIDI file, and the second is the fonted MP3.
These examples do not show the full potential of fonts. I also have one for an SNES sound, a really synthetic sound, insane ambient pads, and more, so be sure to say exactly what you want as that way I will be able to give you what you want.
