It is difficult to automatically process files unless there is something consistent use for making decisions. the best solution would be to buy an inexpensive sequencer program (you can get old versions of Cakewalk for very little on e-bay) and spend a little time learning it. there are also some free programs but i forget their names. i write programs that process midi files and have one that shortens files for the purpose of making sample files. it could be modified pretty easily to split a file into several pieces but there are a few requirements. there has to be something recognizable at the points where you want the splitting to occur. this could be a period of silence of a duration that did not occur elsewhere. then you need to be able to decide what to call the new files made. the program could just give them sequential number names and could duplicate all the internal text information in all the files. i also have a midi file player that i wrote that could be modified to allow you to split a file while it was playing. You could split the file right after the first song and then have two files, the first part and the rest in another file. Then you could repeat the process until you had split off all the individual songs. This might be more of a job to write but not a huge effort. I am traveling and finding that i have some time while waiting for others and getting bored. I could probably use this dead time to write a program. Although I really recommend getting a simple sequencer and learning how to use it, if there is sufficient interest i will write the file splitting program.

Hi Spencer I think that you, Bill Brandon and Mark Fontana deserve a huge vote of thanks for all that you do to help members of our group. Where I am in Scotland there is a dearth of Disklavier Technicians and I have found the help in this forum to be first class. Best wishes and keep up the good work. Owen

If this is really a one-off, and isn't the sort of thing you need to invest time in learning... I'm happy to do it for you. Send me the midi file, and I'll send you back the pieces. There's a good chance I won't know the song titles, so you'd have to rename them yourself. -Kevin

would not be terribly difficult to make a midi file splitter. if there were enough demand i could convert one of my existing programs to do the job. i think the easiest method for a total novice would be to have a midi file player that would split off a file every time you clicked a certain key while it was playing. this would be pretty easy to write but as with any programs it is the details that make a simple program get pretty complicated. adding appropriate meta data and changing files names are all possible but to add all the options that users might want would increase the programming job considerably. how about a player that had the usual play pause stop buttons and that you could interrupt at any point with a click of a button of key and then enter the name you wanted for the file split off?

>> With what (possibly free) program is possible to split in two a midi file? Anything called a "sequencer". I don't need to know about free ones, but I'm sure there are suckh and someone will recommend one. Note that a midi file often contains setup data - sounds allocated to tracks, volumes etc. - at the start. If you remove this section and start half way through the song, you may get unexpected results. If all you want to do is shorten the file, GNMIDI (http://www.gnmidi.com, shareware) can do that. Very flexible for this sort of thing, and avoids any worry about manually cutting and leaving out vital messages from earlier in the song. It isn't too hard to cut out the end of a song using a sequencer, but taking out the beginning is trickier.

Adding graphical display that was useful would probably be a lot of work. Could show time to next playing note. Might be good to delete empty space at beginning and end of each section and add fixed amount of silence. Also probably want to retain all events at beginning of file. It is difficult to anticipate all the strangeness that can occur in midi files. Will think about this and try to guess whether it will be an easy job or a big one. Sent from my iPhone

Amazing. Audacity works great to edit midi, even has a piano roll view. As long as you can recognize the place where you want to split, visually, it is great. Too bad you cant listen to the file Sent from my iPhone

Great solution ! For MidiYodi I made some experiments and for the resulting cropped files MidiYodi always puts at their beginning the original data for proper playing that is part of the original file

Good morning, everyone. I am a long-time user of Audacity for editing audio files. I’m astonished to discover that it can open, edit, and export MIDI files! At first blush, it appears that the editing is limited to cut, copy, and paste. Prior to learning about Audacity, I was going to comment that when splitting up a Disklavier file, you really should find a way to do it and keep the messages that appear at the beginning of the file, which include: —a variety of Yamaha SysEx messages —GM reset message —controller 7 (volume) message (typically setting the volume to 100) —patch message Unfortunately, Yamaha has not published a chart of the SysEx messages, and I therefore don’t know how important many of them are. I do know that some of them relate to: —reseting the internal XG tone generator —specifying which channels contain left hand and right hand data —model of Disklavier I am reasonably certain that other messages may relate to whether video-sync is being used, whether CD sync is being used, and whether the file contains XP data. Speaking of XP data: We have had a long standing problem that the Disklavier PRO uses various controller messages to store extra bits of resolution for hammer velocity, key release velocity, and pedal positions as well as data for key-down velocity. These messages much occur in the correct order in the MIDI file and must be preceded by polyphonic aftertouch messages that effectively determine the association of these controller messages with specific notes. Unfortunately, when you load a MIDI file into a typical sequencer, the sequencer imports the MIDI data into its own format and in doing so, messes up the ordering of the messages. When you export a new MIDI file from the sequencer, you have lost the integrity of the XP data (although there normal MIDI data in the file will play just fine). If anyone wants to develop an application to split up XP MIDI files, this issue should—ideally—be taken into consideration. I look forward to playing around with Audacity, MididYodi, and GN MIDI to see if any of these applications can treat XP data appropriately.
