I converted all the JIS source code to UTF-8. (If you're gonna be 世界中 (sekaijuu -- world-wide, world-over) then use Unicode, man).
Not even my bugfixes were upstreamed and I'm not mentioned in the contributors page anywhere.
I had to fix things just to make it fully usable. It had issues opening devices, and a crash also.
/s?
I thought the GP was so obviously sarcasm that it didn't need an explicit tag
The UI isn't 100% self explainatory, but incredibly sleek and probably worth learning if you compose/edit midi a lot.
I had previously tried Sekaiju and another tool whose name I forgot, but I felt like they were aimed at more experienced users and assumed a higher level of knowledge about MIDI terms and concepts (of which I know very little), so much of the interface went over my head. MIDI Editor was good enough for my simpler use case.
We're not open source, but our free product has pretty good MIDI editing for conventional use cases. There's also an interactive MIDI composition AI model.
The advantage for me was it came up near the top of the Google search results, I downloaded it, and it did the thing I was trying to get done.
In other words, for me it was good enough. So I didn’t spend time “shopping” and was able to pick up my creative work again quickly.
If later it isn’t good enough, I can try something else.
But my use was just temporary to solve a specific problem.
I used Musescore to write the final composition for my beginning music theory class at community college and wanted to load the MIDI into my QY700.
But Musescore was adding an A3 metronome to its output when playing on all four channels and was setting all velocities to 0. So the recordings on the QY700 would require a lot of manual editing.
Then Live Lite did not work the way that would be sensible (upper tiers do of course). Plus, deliberate dawlwessness means I am not very experienced with it.
Anyway, I downloaded MIDI Editor and got the MIDI files into the QY700. Then once the pressure of the problem was gone, I had a play with Live Lite and figured out how I can write MIDI from it to the QY700 so I may not need MIDI Editor in near future workflows.
But how I work is constantly changing…
Update: so I looked at it a bit, still not a musician but it looks like lmms can only export single midi tracks at a time. So probably useless for actually creating a midi song. If you really wanted to beat your self up you could set up each track as a midi output channel, then play the song while recording the midi stream. But that does not sound like much fun to me.
"Not many devs have the requisite knowledge of MIDI" ..in a DAW?
Searching I get a link to a URL that looks like it could have been the Seq24 home page, but Firefox throws up a security warning for that domain. There is also a hit for this project that claims to be based on Seq24 and that has commits as recently as a few days ago, so maybe this is worth looking at:
