Sry for (unrel) OP pic, btw

Its what i had in store

Midi still works that way. If you play a midi file, it will play with sounds built into your soundcard. It's just like emoijis. They display with whatever the built in emojis in whatever device or app you're using. It's because they don't actually store sound or images, just codes that say:

>:Dog emoji:
or
>:Eb4 1/4 note on tuba sound

That's another thing too is that each soundcard comes loaded with a midi instrument for all the kinds of orchestral instruments and much more.

Like this is how different an emoji can look depending on the app. Because all its sending is a code to find that emoji in that app's database.

You can change what you default midi soundfont is.

https://blog.markheadrick.com/2012/10/01/how-to-make-midi-files-sound-better-in-windows-7/

>To change the default MIDI instruments on Windows, you'll need to replace the Microsoft GS Wavetable Synth with a different soundfont or MIDI driver. This can be done by installing a third-party driver like BASSMIDI, CoolSoft VirtualMIDISynth, or a VST MIDI driver. Alternatively, you can use a SoundFont player to load different SoundFonts.
Steps to Change Default MIDI Instruments:

<1. Choose a MIDI Driver or SoundFont Player:
BASSMIDI Driver: An open-source driver that supports two ports (16 MIDI channels each).

>CoolSoft VirtualMIDISynth: Emulates the EMU sound chip of Creative Soundblaster cards.
>VST MIDI driver: Uses VST plugins instead of SoundFonts.
>SF2 Player: Software like VLC or LMMS that can load SoundFont files (.sf2

This video explains how to have the game's midi play different soundfonts.

Why? They're still shit.

MIDI is a pretty cool tech. It was invented in the early 1980s as a standard by American and Japanese synthesizer manufacturers, ensuring that every equipment could exchange musical data easily, because back then everyone had their own special incompatible protocol. MIDI is still used today in most music software.

Then you had General MIDI which is an extension specifying some standard sounds that often sound cheap as hell, but you could make your own General MIDI bank of sounds with a Soundfont and play fart sounds instead of piano sounds or something, or have high quality sounds. It wasn't just sound cards, quite a few people had a module like the Roland SC-55 or SC-88 to play the music of DOOM for example. I think Nobuo Uematsu also used a SC-88 to compose Final Fantasy music for the SNES and Playstation games.

The problem of MIDI is that the resolution of the data is 7-bit wide, which means all the data being interpreted by a synthesizer or module is limited between 0 and 127.
This is pretty limiting, especially if you want to make microtonal music or do subtle modulation of sounds.
They are cooking a MIDI 2.0 standard with a better resolution but it will take a long while to get ratified and adopted by everyone, at least one decade or two. For now we have a extension of MIDI called MPE allowing per-note modulation and that kind of stuff but it's hacky.

midi is a pretty cool way to transmit music when your storage space is limited, think about it, those developers from back in the day were crafty. meabwhile nowadays you get shitty software that eats up 2gb of memory just so you can edit a txt file

>This is pretty limiting, especially if you want to make microtonal music
That doesn't apply to pitch.
< MIDI pitch bend messages have a precision of 14 bits, which translates to 16,384 possible values (0-16383). The typical default range is +/- 2 semitones, but this can be adjusted. The center point of the range is usually 8192, with values below representing a bend down and values above representing a bend up.

<http://microtonal-synthesis.com/MIDItuning.html
<The MIDI Tuning Standard was ratified by the MIDI Manufacturers' Association in January 1992. Credit should be given to Robert Rich and Carter Scholz who wrote and lobbied for this addition to the MIDI specification. Manufacturers have the option of supporting the tuning standard partially or in full. It is featured on some Emu and Ensoniq instruments. Currently they implement only the non-realtime features of the standard.

>The frequency data format allows for the precise notation of frequencies that differ from equal temperament.

>"Frequency data shall be defined in [units] which are fractions of a semitone. The frequency range starts at MIDI note 0, C = 8.1758 Hz, and extends above MIDI note 127, G = 12543.854 Hz. The first byte of the frequency data word specifies the highest equal-tempered semitone not exceeding the frequency. The next two bytes (14 bits) specify the fraction of 100 cents above the semitone at which the frequency lies. Effective resolution = 100 cents / 214 = .0061 cents."[1]

>This higher resolution allows a logarithmic representation of pitch in which the semitone is divided into 1282 = 214 = 16384 parts, which means the octave is divided into 196608 (logarithmically) equal parts. These parts are exactly 100/16384 cents (approximately 0.0061 cents) in size, which is far below the threshold of human pitch perception and which therefore allows a very accurate representation of pitch.

>or do subtle modulation of sounds.
I think it's really enough for all the CC messages. But:

>some devices and applications can utilize higher resolution MIDI, typically using 14-bit values to achieve a range of 0 to 16,383. This higher resolution can be implemented using methods such as:

<Pairing two CC messages: One message for the most significant byte (MSB) and one for the least significant byte (LSB).
<Non-Registered Parameter Number (NRPN): These are messages specifically designed to allow for a larger number of parameters and a higher resolution.
<Registered Parameter Number (RPN): These are standardized high-resolution messages
