To demonstrate, this test file is a single record Music Finder file; which opened in a hex editor looks like this:
This file has only ONE record. If the file was a multi record file, the following records are added at the end of this file.
The header is the first 36 bytes. Yamaha has used several formats, some keyboard specific and some of the "NetCommon" type.
As the format has never been published the idea about this has never been fully revealed. However most keyboards read Music Finder files with all headers.
The last two bytes in the header (index 34 and 35 in the first black square) are the total number of records in the file. In this case this number = 1, which is written 00 01.
Now comes the record(s). Each record is 92 bytes long.
| # of bytes | Function | In this file | Marking |
| 2 | Two blanks | 00 00 | None |
| 2 | Record serial number (0-indexed) *) | 00 00 | Black square |
| 2 | Internal style number **) | 1C 00 (= 7168 in dec.) | Green underline |
| 2 | Time signature | 03 04 (= 3/4 time) | Red underline |
| 2 | Tempo | 00 3E (= 62 in dec.) | Blue underline |
| 1 | Fav, S1 and S2 ***) | 00 | Black square |
| 32 | Song title | 41 6D 61... (Ama...) | Yellow underline |
| 16 | Genre | 52 26 42... (R&B...) | Brown underline |
| 32 | Keywords | 68 79 6D... (hym...) | Gray underline |
| 1 | Intro/Next setting ****) | 24 (= 36 in dec.) | Black square |
*) if there were a record more in the file, the serial number of this record would read 00 01
**) to get "Internal Style Number" please read here. Sorry there is no easier way!
***) "Fav" = Favorites (value = 1); "S1" = Search 1 (value = 2); and "S2" = Search 2 (value = 4). Values are added. E.g. value = 5 means: Favorites = Yes and Search 2 = Yes
****) "Intro" = Which intro will be played at start; "Next" = Which part will follow. Values are added.
| Intro values | Next values |
| Off = 0 * 16
Intro 1 = 1 * 16 Intro 2 = 2 * 16 Intro 3 = 3 * 16 Main A = 4 * 16 Main B = 5 * 16 Main C = 6 * 16 Main D = 7 * 16 Ending A = 8 * 16 Ending B = 9 * 16 Ending C = 10 * 16 | Off = 0
Intro 1 = 1 Intro 2 = 2 Intro 3 = 3 Main A = 4 Main B = 5 Main C = 6 Main D = 7 Ending A = 8 Ending B = 9 Ending C = 10 |
E.g. value = 24 (hex) = 36 (dec) = 2 * 16 + 4 means: Play "Intro 2" and continue with "Main A".
In the Music Finder File Manager software the sample file will look like this:
Notice that the Internal Style Number is shown as <7168>. This means that the selected keyboard model (PSR 1500 - see top line in image above) does not recognize the style defined in the Music Finder record.
