Some of these iron disks are damaged or covered with rust. Hence it was not always possible to decipher the record's number or the title of the song. Needless to say that the quality of these recordings is poor, if measured with nowadays (CD) standards. However, given the technology of that time, I think they sometimes represent a remarkable achievement, if judged from an purely artistic point of view.

Convert to Midi with : DiskOCR

All songs have been converted to (more or less) equivalent Midi files, by making an Optical Scan of the disks and determining the coordinates of the holes in the disk. A mathematical model of the MusicBox was built into the DiskOCR program, which interprets these coordinates in terms of duration and tone heights. The output of (the last version of) the program is a Standard Midi File.
(The coordinates of ALEXANDER'S RAGTIME BAND were done by hand, originally, because I wanted to be sure that the recipe would work !)

Here comes the list of original (300 DPI) scans of the above EDELWEISS records:
1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 .
Download the executable. Then convert a sample Optical Scan of an iron disk from the above JPG list to BMP, kindly remove labels 1 .. 12 (with Microsoft Paint for example) and try for yourself. Or rather use a (much bigger) sample from the corresponding ZIP of BMP images, the advantage being that they can be used for rendering immediately.

In case you want to OCR your own (EDELWEISS) disks, the following recommendations are issued:
