As I've also posted on "Pianist Corner" here : http://www.pianoworld.com/ubb/ubb/ultimatebb.php?/topic/2/11296.html#000005
As to why I would want the midi file when I have the mp3, it's simply for myself (and others like myself), who would use the midi file to learn to play the piece. This is done via digital pianos that support this feature, such as the Yamaha DGX-505. Thanks to such technology, it has enabled the wonderful world of piano to reach out to many more people.
Certainly no commercial motives here. As I've said, it's for personal use - for me to learn to play the piece, as well as for any others who would also benefit in this way. I've managed to self-learn George Winston's "Variations on the Kanon" using this very method. It took a while and loads of practice, but I can now perform a near perfect piece of the George Winston version. David Lanz's version will be a lot more challenging, but they're both beautiful music and worth the effort.
And yes, it's certainly asking a lot (the request for someone else to perform and record a near-perfect midi file of the song, without offer of financial compensation), in terms of practice and performance time; however, it's quite likely and considered, that whomever would seriously consider such a request, to be a pianist who would him/herself have an interest in this piece. That is to say, it would be done partially out of his/her interest, too. But he/she would certainly have my appreciation and gratitude.
And if the midi file does get re-distributed non-commercially (for the benefit of others who would learn from the midi file), I would surely include the rightful credits, of both the original composer David Lanz, as well as the performer of the midi file.
Thanks to all who replied.
I've just noticed a thread on the "Adult Beginner's forum", that has a link to a David Lanz midi file site : http://www.carmay.com/DavidLanz/midi.htm
Unfortunately, it doesn't have "Variations on a Theme from Pachelbel's Canon in D Major". Pity.
Someone suggested :
--- Run the mp3 through a midi converter. They have free trials, and some shareware online. ---
I've already tried that, and tried out shareware trial versions of several different mp3-to-midi software. It takes considerable technical and professional know-how (which I do not have) to tweak all the different settings, and even then, the process of converting mp3 to midi, is far from perfect. From my attempts, the results still contain lots of extraneous notes, or missing notes, etc.
Thanks for the suggestion anyway.
