Kendrilian, join the club. Everyone else at the VGmusic forums can't wait for his next song either.
Now, you all remember the aforementioned FF6 Boss Battle remix by him? He had also posted the MIDI transcription of it, it's the same exact file his synth played in the mp3 recording, XG SysEx and all.
I checked it out in my sequencer, and boy, was there a lot of SysEx messages. Naturally, since I use XG hardware myself (I think my hardware is in the MU80 class of synths, but I'm not sure), I gave the MIDI file a spin on my system. Unfortunately, the MU1000 class uses some newer SysEx messages that my hardware can't understand completely, like how to tweak the distortion effect, and so on. I was definitely getting Distortion effects, but my hardware's understanding stopped there. Apperantly he also used the SysEx to do volume stuff too, because it was just totally way off, and my card wasn't sure how to correctly do the pick slide effects.
Then again, the synth he uses, AFAIK, has a 20meg wavetable ROM where his instruments are stored, whereas mine is a 2meg ROM.
