The MIDI Protocol: MIDI Messages | Simon Hutchinson
Музыка
An overview of MIDI messages and how to construct this musical performance information from status bytes and data bytes.
Building off of our last discussion of MIDI ( • The MIDI Protocol: Bit... ), I go over MIDI channels, and then go through the messages for Note Off, Note On, Polyphonic Aftertouch, Control Change, Program Change, Channel Aftertouch, and Pitch Bend Change--understanding each bit's role in these messages.

I used to be an IT guy and have been using MIDI for nearly 40 years, but watching your video is the first time I really understand what is going there. Dave Smith and Kakehashi Ikutaro were geniuses!

best explanation on YT, THANKS!!

This video repeatedly mentions "127" voices, or cc messages, etc. There are actually 128. 2^7. The 127 comes from the numbering system being 0-based, so the first is 0, second is 1... one-hundred twenty-eighth is 127.

What a tremendous video, I’ve been a guitar player for many years, and recently started playing 80s and 90s synths. While I learned practically how to daisy chain them, I always wanted to know how each instrument “knew” which channel was which. Thanks so much!

Really great video man. I have been wondering exactly what midi protocol looks like for a while now. I have a project in my microcontrollers class using a PIC24 microcontroller and MPLABX, and I am strongly considering trying to work with some amount of MIDI protocol. If I don't use it then, I'm sure ill try building something with it sooner rather than later
great video! helped me a lot :)

Thanks for your explanation! It's very useful for a project I have, do you recommend any video where they use assembly to transmit these midi packets (bytes) through USART to the computer (with an Arduino Uno ATMega328P uController, but using the assembly code instead of the more easy high level programming) to assign some keys (push buttons) to different things in the DAW's (FLStudio, Ableton, whatever)? Because I found many videos they do this but with the C-like code that uses Arduino, importing libraries, I tried to debug the libraries themselves, but I did not find a good explanation of the bytes sent, as you did in this video, I saw the Note on and stuff but it was not that clear. Thanks in advance if you know some source! If not anyway thanks for the video is very clear ^^!
Hi Simon, I came across your video while looking for ways to transcribe MIDI Messages through Image Inputs I was slightly interested in understanding if some other triggers could be used to encode these messages (such as the RGB Data, and equating it with similar data bytes in a way?) This may allow people to sonically experience photographs. I'd love to hear your views and take on this.
@SimonHutchinson

I'm not sure I completely understand your question, but, in short. You can convert all data (including MIDI data) into another kind of data (like RGB values). Check out more here - kzread.info/dash/bejne/gHypyNiynMqWhto.html
Thank you my friend! We're LUCKY to have access to knowledge/explanations like yours. I have 1 question if anyone has time to clarify: ...Is this dual functioning of the Data Byte's 1st Bit correct? 1) '1'xxxnnnn designates it as a Status Byte as opposed to Data Byte, and 2) The '1xxx'nnnn portion specifies the kind of message we're sending, i.e noteOff(1000nnnn), noteOn(1001nnnn), Polyphonic Aftertouch(1010nnnn), Control Change(1011nnnn), Program Change(1100nnnn), Channel Aftertouch(1101nnnn), Pitch Bend Change(1110nnnn), or System Exclusive(1111nnnn) I ask because I want to be sure the first Bit of a Data Byte serves two purposes. EDIT: spelling

Hi Simon thanks tons for your videos ! can you tell me what using an inputhandler call back does that is different from the standard way midi apps handle inbound messages? - can you pretend I'm dumb as shit and explain accordingly because I don't get it at all? Thanks!
Hi, what is the function of the "Song Select" midi command. Status byte F3 (hex), followed by 1 data byte ? If I sent this to a synth, would it start playing the specified song??

Hello Simon! I have one question about the 1111nnnn status bytes. I've read that some sustain pedals will only work to their full capabilities only with keyboards of the same brand. Could the be due to the use of this "1111" data? And, if so, could manufacturer data be "replicated" to make a keyboard believe a pedal is from its brand?
@SimonHutchinson
Жыл бұрын
I don't think that's correct. Sustain pedals are supposed to be Control Change Messages on controller number 64. So they shouldn't have much to do with System Messages or the brand of the pedal/keyboard. en.wikipedia.org/wiki/General_MIDI#Controller_events
@AlvaroALorite

@@SimonHutchinson and could it also send that kind of data let's say in the first press? Another thing that confuses me is how sustain pedals use Jack audio cables as MIDI data cables.
@SimonHutchinson
Жыл бұрын
The pedal connects to the keyboard (analog) electrically with a 1/4 jack, and the keyboard is what converts that cable into MIDI.
How to get revive MIDI data ??
I need your big brain a second! How do you work out MIDI channels from a Byte? Is there a calculation you can use or a formula?
@SimonHutchinson
2 жыл бұрын
So, the status byte is 8 bits: 1 (Status byte marker), XXX (Type of MIDI Message), NNNN (MIDI Channel). Look at the NNNN. If it's 0000 - MIDI Channel 1 0001 - MIDI Channel 2 0010 - MIDI Channel 3 0011 - MIDI Channel 4 0100 - MIDI Channel 5 0101 - MIDI Channel 6 0110 - MIDI Channel 7 0111 - MIDI Channel 8 1000 - MIDI Channel 9 1001 - MIDI Channel 10 1010 - MIDI Channel 11 1011 - MIDI Channel 12 1100 - MIDI Channel 13 1101 - MIDI Channel 14 1110 - MIDI Channel 15 1111 - MIDI Channel 16 ... I think I got that right.

@@benparamoresound338 if you are using a programming language to get the channel from a byte, you can just do a byte AND 16 to mask off the rest of the bits to be 0. The remaining number is between 0-15, if you add 1 its the channel number between 1-16. Hope thats helpful
So, 2 to the 14th.. I'm not going to go through it :D
Super explanation but please leave out the music :( Although I really like weirdly sequenced ambient wavetable stuff, this makes it a bit hard to follow. But this may be my ADHD kicking in, so what do I know... Anyways, finally a clean explanation of MIDI I was waiting for for years haha
