Add MIDI export

[davidgerard]

LMMS presently only saves in LMMS XML, which nothing else reads.

Pretty much everything ingests MIDI, so MIDI export of LMMS projects would greatly increase interoperability.

[diizy]

This would possibly be a nice feature and this has been discussed several times, but there's some hurdles to overcome.

For instance, how to deal with features unsupported by MIDI (eg. per-note pitch bends and panning)? What MIDI file format to use?

[unfa]

I think that we could begin by exporting single clips as midi files through Right Click → "Export As MIDI..." → Save Dialog Box → file output.

Sometimes I'd like to get some MIDI data out of LMMS to process it with another software, but I can't.

Think unsupported like per-note pitch bends could be omitted. I hardly ever use that anyway - ZynAddSubFX can't play that either.

[davidgerard]

Yeah, we obviously can't be expected to export stuff that's literally not supported by the spec.

[softrabbit]

@diizy, what do you mean "what MIDI file format to use"? If it's type 0 vs 1, I'd say type 1 (the one with tracks) is a pretty obvious winner. Or did you have something else in mind?

[Sti2nd]

It seems like MIDI support automations and even pitch bend :0 http://www.soundonsound.com/sos/1995_articles/nov95/midibasics4.html

It blew my mind. Here is an example https://drive.google.com/file/d/0B-1kciTMrTBZRHF1dk9XUVRWcFU/edit?usp=sharing from 0:47 the file fades in if you play it on Windows Media Player.

Hey guys, any news about a MIDI export solution ? It seems like a must have feature for any music composing software.

Are you volunteering to implement it?

Right now no :), I found another solution.

[mohamed--abdel-maksoud]

Hey, I've been a silent fan of lmms for a while and I'd like to see the MIDI export added. I volunteer to implement it if needed.

@mohamed--abdel-maksoud,

Great.

It doesn't appear anyone else is actively working on it. Please issue a pull request once you start so we know progress is being made and have the opportunity to offer advice asking the way. :)

@mohamed--abdel-maksoud Amazing! Any help is greatly appreciated :-)

[mohamed--abdel-maksoud]

cool, I'll have a go on it from today, wish me luck :)

nice :)

First of all I want to thank @mohamed--abdel-maksoud for the outstanding work on the MIDI export feature.

Now I want to ask here if it's desirable that we are able to export only a single instrument track to MIDI, instead of the whole project.

[Sti2nd]

It is not that important, since you can delete the undesired tracks in another program anyway, but it can be useful I guess. So if you want to do it, it can't harm?

Well, obviously we'd take anything that improves the software but moving forward, this may prove to be useful, perhaps for a drum beat once we start to focus a bit more on dedicated drum instrument tracks (we instead tend to use a bunch of independent tracks for a drum pattern). I'm also not sure if this would warrant a dedicated context menu or button per-instrument. What do you think @badosu?

[badosu]

I was thinking of using the instrument context menu on the widget, that wheel button. Anyway, @mohamed--abdel-maksoud has already implemented modularized track export, so if this is needed in the future it's easy to do.

FYI, this has been implemented for the future 1.2 release per #1686. Added to release notes. 👍

[dednikko]

Yeaaaahhhh! I just want to let you know how much this will improve my life.
You guys rock so hard!

Great news!

I've had great time working on this feature, lmms is a beautiful piece of software :)

@Baccanno I've edited the post now. FYI quoting you now gives
