I wonder why we can't play the files then directly by clicking on play here. That is what I meant.

Oh I see.

All the songs that I did on the Casio keyboard are in ogg files.

Collectively replying to the posts, at least those who do make sense and those I consider constructive rather than aimed solely at discrediting my effort and the results I've got, as their sender usually tries to. I just want to tell their sender to keep in mind that what BGT lets me do is only to play and stop certain sounds when certain keys are pressed or released. You can't even adjust the velocity so comparing that piece of BGT code with VST plug-ins is purposefully exaggerated and unreasonable.
So how the notes stop when I release the keys is not my problem, and as far as I know, not something I can fix. It's just BGT's stop command that I used and I don't really think I could've made the sounds stop in any other way. And I don't still know what clarinet you're talking about but it's the samples that can be improved rather than the code. So I may work on that.

If I have to save the file in any case then I would use FileExplorer to navigate to the file and play it instead, which basically works similar to Elten's file manager. It's a shame we can't directly play MIDI songs on here. By the way, what is this sound font that Elten downloads? Can I just not browse for one on my computer and command Elten to use it?

It has to be named a certain way, but you could copy one you have and rename it to soundfont.sf2 and put it in %appdata%\elten\extras.

Got it but I don't think I would bother to do any of these when I can just hit Enter on a file in File Explorer. I still wish to know if the sound font that Elten downloads is high-quality though.

By the way, I did download the soundfont to get the answer to my question straight ahead and then realized that it is now possible to directly play MIDI songs without saving them just by hitting Enter on them and choosing Play.

To post 423, just be patient. It takes a few seconds to start.

Me and my friends made Espeak sing. It is a very silly greek song that we created for fun but we did manage to actually make ESpeak sing

Even though I don't know the lyrics, that was fun to listen to.

George, as far as I know, conversion from MIDI to audio is already done using soundfonts, just as taking the MIDI data and then converting it to audio when playing MIDI songs. So I think I would be right to say that you are already converting them when you play them. So yes, you should need a soundfont to convert a MIDI file to any other audio format.

To post 436: It's fun indeed. One thing you could do is synchronize eSpeak's syllables with the notes more precisely.

To post 429, thanks for the explanation, I totally understand now that this is beyond your control with the tools you use. It's only until now that I have read your entire response. And I was referring to post 410 when talking about the clarinet. The sound itself is fine, but then there's the problem you have now elaborated on, which, as I said, am very thankful for.
I should add though that BGT's not the way to go if you want to create something with midi that is meant to sound as realistic as possible. But it's certainly very original of you to do so, not sure if anyone else used a game toolkit for creating music.

@ Mohammad and his friends, god job guys, although I think I understand 1 word of it, but still, keep up the good work. :) :)

well George, that is not the correct harmony for it.
