Files with SIB extension are created by Sibelius application. SIB files contains a sheet music document. Music notation can be created using MIDI devices or other software tools.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the SIB file after converting to MIDI may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from SIB to MIDI to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting SIB to MIDI does not meet your expectations, you can simply try to find on the Internet a different version of your file in SIB format, properly converted to a MIDI file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file SIB the desired result was not achieved, you can try to change the format of SIB file to other than MIDI. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your SIB file converted by someone else, and the attempt to convert it to MIDI on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the SIB file in its original format (without conversion to MIDI file). Such a solution will be difficult to implement, but it certainly will give the best result.
