It's not difficult to convert style files for the PSR-E453 and other XGlite models. Following are the steps I go through to do this. They may look rather laborious, but once you've converted a few styles and have familiarized yourself with the procedure, you should be able to do it fairly quickly without having to refer to a list of steps.
(1) Make backup copies of the style files and work only on the copies.
(2) Use the "Style Format Finder" program (http://www.jososoft.dk/yamaha/software/sff/index.htm
) to see whether the style files are in the SFF2 format or the SFF1 format. You can do this for an entire folder of style files at the same time.
(3) Use the "Style Format 2 Converter" program (http://www.jososoft.dk/yamaha/software/sf2c/index.htm
) to convert any SFF2 style files to SFF1 style files.
(4) Use the "Style Old Format Converter" program (http://www.jososoft.dk/yamaha/software/sofc/index.htm
) to convert the SFF1 style files to an older SFF1 format. At the minimum, you should check the following two options:
- Convert Mega Voices
- Use .sty extension
You may also want to check the following three options, although they aren't required:
- Delete OTS Section
- Use old CASM Format
- Max. resolution 480
(5) At this point you should have a style file that the PSR-E453 can load-- unless it's too large. (If I remember correctly, the limit is roughly 50kB.) However, even though the PSR-E453 can load 4-variation style files, it cannot use the C and D variations, only the A and B variations. If a given style file is small enough to load and the variations you want to use are already in the A and B positions, then you can probably use it as is (although you should still consider performing steps 6 and 7). But if you want to use the C or D variation, or the file is too large, use the "Style Remixer" program (http://www.jososoft.dk/yamaha/software/sremix/index.htm
) to rearrange the sections so the two variations you want to use are in the A and B positions. It's also a good idea to delete any sections that the PSR-E453 can't use, although that's mainly to keep the file from being any larger than necessary. Note that if you want to be able to use all four variations then you'll need to make two copies of the style file, one with the A and B variations, and the other with the C and D variations (but moved to the A and B positions).
(6) Use the "Style Revoicer" program (http://www.jososoft.dk/yamaha/software/revsty/index.htm
) to inspect which voices and drum kits are used by the style file, and to convert them as needed to voices and drum kits which are available on the PSR-E453. You can also use the "Mix Master" program (http://psrtutorial.com/MB/mixMaster.html
) to do this. Note that this is largely an optional step, because in many cases when the specified voices or drum kits aren't available the keyboard will simply default to the GM1 voices and drum kit. But that isn't always the case; sometimes the part that uses the unavailable voice or drum kit will go silent instead. Also, the keyboard may have better-sounding alternatives than the GM1 voices and drum kit. Thus, it's strongly advised that you edit the voices and drum kits used to be sure the style is using the best ones available.
(7) Another optional step is to use the "Mix Master" program (http://psrtutorial.com/MB/mixMaster.html
) to remove MIDI events that the PSR-E453 can't respond to-- e.g., DSP insertion effects. This is mainly to keep the file from being any larger than necessary. On the other hand, it's strongly advised that you edit the Reverb and Chorus events to be sure the style is selecting a Reverb Type and Chorus Type which is available on the PSR-E453.
