Has anyone had success scanning sheet music into a midi file?

That would be a challenge for software, but if you find such a thing, let me know, I could use software like that.

There are a couple of scanning programs; one is connected with Sibelius notation software. The other (I can't remember the exact name) was from a company called ScanSoft, which has sold out to someone else. The demo ScanSoft program I used came in two or three versions, each one more powerful than the other. I used the least powerful and had decent success except for things like ties and other incidental marks. I understand the most powerful of the programs DID see and employ all the notation on the sheet music.

Well lookie what I found:

They have a downloadable demo, I'm going to give it a try and see if it works.

Price is $399.00 for Pro Version.

That's the one; it's a pretty powerful program.

I have been using SmartScore 3 for quite some time and quite impressed with scanned the results.

I use this program to, relatively quickly, take an existing printed leadsheet (including notes, chords & lyrics) and have it transposed, and printed out in another key.

This does requires a little tweaking & editing of a few of the translated notes, chords, and/or lyrics of the the scanned music, but I'm very impressed overall because it saves a LOT of time of having to enter the music manuscript into the computer, manually from scratch (one note/chord & lyric word at a time). After SmartScore interpretes the scanned music, it only takes me about 10 minutes to clean up the few mis-interpreted notes/lyrics, vs taking up to an hour to enter each and evey note, lyric word, and chord into the computer manually.

My only complaint is that its not possible to alter/change the number of measures per line (system) from the original scanned page. I was advised by Musitek though that they are currently working to implement this feature in a future (next?) version.

With each subsequent release version of SmartScore, I continue to see improved accurate music recognition. Though I'm anxious to see continued feataure advancements, I am very happy with this program and think it's the best of its kind.
