Is there a way to convert a Standard MIDI File (SMF) from Type 1 to Type 0? Obviously, some advanced features might be lost, but that's okay.I imagine there might be a software program which does this. I've tried using a few different editors & sequencers, but they either don't provide the option to pick a specific Standard MIDI File Type, or don't output Standard MIDI Files at all. (MuseScore, Timidity, Muse) ContextI have a Standard MIDI File (Type 1), which I composed via. My keyboard (a Yamaha ) has the ability to construct lessons and display scores for MIDI files, but only for Type 0.Edit: I'm looking for open source software, and preferably available for Linux. There are several computer software sequencer programs that have a legacy of a great deal of capability in manipulating MIDI data. They can input and output and convert between Standard MIDI Files of Type 1 and Type 0.I know of one such program, for Windows and Mac OS X, but there are certainly other programs that can do this.If you do a Google search on the terms convert smf midi file type 1 type 0you can locate other utilities and programs.No 'features are lost' between Type 1 and Type 0.
All the MIDI data will be retained in either type; it's just organized differently. Seeing as you are particularly interested in Linux and that I found your question due to a common interest, Here are a couple of suggestions that may help:.SMFformat0, part of the Ruby library (not a Ruby Gem, however), which you can use like this: $ SMFformat0 infile.mid outfile.midYou need to download the tar file and then run it. If you're technically adept I am sure you can work it out from the website;)., a command-line MIDI sequencer and filter for BSD and Linux. Which can import and export. It will import type 1 or 0 but it only outputs type 1. It's therefore suitable for converting from type 0 to type 1 but not the other way around.Use ALSA: $ arecordmidi -p 14:0 output.mid &$ aplaymidi -l # to identify 'arecordmidi port 0' device (e.g. 129:0)$ aplaymidi -p 129:0 input.mid$ kill%%This last one works because arecordmidi creates type 0 files by default but it has the disadvantage of being like taping tapes - it's in real time.I am surprised this subject is so lacking answers for the open source / linux world.
Use Awave Studio. It can convert anything to anything else.' Awave Studio is a multi-purpose audio tool that reads a veritable host of audio carrying file formats from different platforms, synthesizers and trackers. It can be used in a variety of ways: as an audio file format converter, an audio editor, an audio and MIDI player, and, last but not least, as a wavetable synthesizer instrument editor and converter.' 'Ever wanted to play a standard MIDI file song that comes with an 'instrument bank' that were created for another wavetable sound card than yours? Awave Studio cannot only make high quality conversions between the most of the major sound cards; it can also load both the MIDI song and the instruments and play it directly for you!' 'Awave Studio can read almost any imaginable audio or instrument file format - over 200 of them in fact!

And it can also write to about 100 of them!' You may find a freeware converter that will do only what you are asking. I always used Awave though cause it's the best. Never really needed to use another program.
Here is a freeware program to do it:Use his 'Midi File Converter'.You need this DLL thing too I guess.' There are 3 different 'Types' (sometimes called 'Formats') of MIDI files. Type 0 files contain only one track, and all of the MIDI messages (ie, the entire performance) are placed in that one track, even if this represents many musical parts upon different MIDI channels. Type 1 files separate each musical part upon its own track. Both Type 0 and 1 store one 'song', 'pattern', or musical performance. Type 2 files, which are extremely rare, are akin to a collection of Type 0 files all crammed into one MIDI file. Type 2 is used to store a collection of songs or patterns, for example, numerous drum beats.
