These are the types of tutorials I search long and hard for. Everything is well explained, even seemingly complex things, without over-explaining. Keep doing what you're doing, bro.

I spent probably one hour, hour and a half looking for a good, well-explained, and SIMPLE tutorial for doing MIDI with Arduino. Yours was the only one I felt good with, thanks a lot man!!!

In case it helps someone following along, I got garbage in the Debug (Serial) window until I changed the serial baud rate to 115200. Thank you, Gustavo!

the code link is broken, can you upload it again?

Thank you for this great tutorial series!!! I just started yesterday building my own midi controller. Birdies like yours help a lot! Greetings from Germany 🤙🤙🤙

Mano, esses videos são exatamente o que eu tava procurando! O jeito que vc ensina e os recursos que voce usa são excelentes! Meus parabens e muito obrigado por fazer esses videos cara, voce absolutamente merece mais atencão, e espero que o algoritmo te abencoe pra que outras pessoas possam ver esse canal magnifico!

IVE BEEN SEARCHING ALL DAY AND THIS IS THE BEST TUTORIAL OMGG

Hi, great video!! I was having a problem when I changed DEBUG 1 for ATMEGA328 1 and it was that in order to recognise the ATMEGA you must uncomment line 36

You're a boss, thx for your generosity! Can't wait to start working on my midi controller.

I appreciate the time you took to really explain everything from top to bottom in this series. Thanks!

Que legal, Gsutavo! mandou bem demais demais demais! muito obrigado s2

parceiro eu passei por varios problemas mas no final, graças a iteraçoes dos meus casos com o chat GPT, consegui montar o setup basico pra fuçar no VCV rack! muitissimo obrigado meu querido, ta de parabens pelo conteudo.. e pa gringo é mais caro kkkkkkkkkkkkkkkkkk

The whole class is so intuitive and easy to understand, thank you so much for this effort. Really learnt a lot from your videos. Subbed and liked.

Thank you so much, this is awesome! I had so much fun building my little prototype, can't wait to get into something bigger now! Just a heads up - I had to close the SerialMonitor before hairless could receive the input from the Arduino. Took me a few minutes of head scratching, but great tutorial I really appreciate it!

It is possible to decide wich exact cc number you want for each knob? Like for example having two knobs and giving the first knob the cc number 17 and the second knob giving it cc number 5?

Very catching! Thank You. Going to repeat it.

Why do I have this in Hairless midi? for example: +35.061 - Error: got unexpected data byte 0x66.

I am getting a weird error called bad CPU type in executqble can you help plees

I am trying to run this, yet the Hairless app is incompatible with my version of windows. Could you maybe create a video on running serialmidi? Otherwise I'll have to get new Arduino (one that plug and plays) and that wouldn't help me with UNO, mega, etc..

Is their a reolacement for Hairless Midi? It nolonger works on my mac. It says its out of date.

Hairless for Catalina: github.com/projectgus/hairless-midiserial/files/4476818/hairless-midiserial.app.64bit.zip

WOOOW BROOO YOU ARE SOOO AMAZING.....NICE EXPLAINING PLEASE KEEP UP YOUR WORK:::: I STAY FOR EVER YOUR STUDENT !!!!!

Error message for me: Midi USB not declared on this scope. I'm trying to turn the arduino into a touch midi, I have the adafruit sheild installed.

I'm so close but I'm stuck. I get this error when trying to upload the code: MIDI.sendControlChange(cc + i, midiCState[i], midiCh); // cc number, cc value, midi channel exit status 1 'MIDI' was not declared in this scope

There should be tutorials like this one in Assembly language :'3

when I try to verify the code ,I get this error "C:\Users\BAPU\Desktop\DIY-Midi-Controller-master\Code - código\en-DIY_midi_controller\en-DIY_midi_controller.ino:54:10: fatal error: ResponsiveAnalogRead.h: No such file or directory compilation terminated. exit status 1 Compilation error: ResponsiveAnalogRead.h: No such file or directory" Can you help me out?

thanks for these series ♥♥♥

how can i add some multiplexer? can i? I wanna do this with arduino mega, i should make like 130buttons... pls help me

you are just awesome man. you are saving my life !!!!!

Hey @Nerd Musician. Awesome videos that have got me tinkering. Hairless Midi will not work on Big Sur 11.5.1 though, it says it needs to be updated by the developer and cannot be checked for Malware. I override gatekeeper and hairless.app opens, but not fully. It hangs and sits there 'not responding' until force quit. Last night I also downloaded the master code from the Hairless github, but I've no idea how to implement it as it wants to open in KICAD which I haven't figured out how to use yet, so I really am lost at this point. I'm neurodivergent so can and do get total brain blocks sometimes, but even after a good night's sleep I am still unable to get Hairless working. Any advice please? Secondly, unrelated directly to this controller. I have a couple of KORG 6p1 thermodiode nutube valves. Any suggestions on what to build with them

I setup everything just as said. Even serial monitor commands are getting correctly but in the Hairless MIDI im getting an error called "FTDI drivers dont seem to be installed. Not attempting any FTDI latency tricks ". I even switched computers but the same error still exists can you please tell me how to fix the error.

Great teacher!! thanks Gustavo

The link for the code is not working :C

Any idea to replace hairless application. It doesn't work with last osx

Wow thanks man... Thanks for sharing your knowledge I was wandering if I can build a guitar pedal for amplitube.. And I sisdnt know how to. Thank you somuch again for sharing knowledge

I did everything you said and put it in debug but when I go into serial monitor it senses when the buttons are pressed but it comes with .?,!+;@‘dj and symbols like that HELP PLZ

Great videos, but I'm still having issues executing the code. The code is verified with no problem when I have "DEBUG 1" , but when I switch to "ATMEGA328 1", I get " 'MIDI' was not declared in the scope" errors on lines 144, 166, 221. I get about 10 or 11 errors. I've cleared and reinstalled the libraries folder, re built the breadboard and gone through the video 4 times with a fresh code download each time. I guess I'm having the same issue as Miguel. Arduino 1.8.12 and 1.8.13 OSX Arduino Uno Any help?

Hairless MIDI is not compatible with my M1 Macbook. Is there any other way? I purchased your couse btw.

I'm having an issue running Hairless Midi on Mac OS X Big Sur, any alternatives?

This was so helpful! Thank you man ❤️

What happens if i have big sur? Cant use hairless

These videos are superb! But dude, you HAVE to make a video about rotary encoders. Include a rotary encoder section in your code. You've only covered 2 of the 3 main controller components.

what midi library should i install for mega16u2 ?

Thanks a lot! Have many problem with sending Midi from Nano to PC, many of the libs don't work

Not working for windows 😢 Any solution please

Brilliant!! Thank you

Hi, How can i made toggle button instead? Example: Button to turn on/off solo button in DAW

I got it all working till using Hairless MIDI, where I'm getting this error: "+11.383 - Error: got unexpected data byte 0xa." Any help?

I've created a MIDI controller with an Arduino and a potentiometer to control the volume of Voicemeeter. The problem I'm facing is that even though the MIDI values sent to Voicemeeter are correct and range between 0 to 127, the software doesn't seem to respond accordingly by adjusting the volume appropriately. I've verified the MIDI channel, control change (CC) number, and even tried different delays between the MIDI messages, but the issue persists. It seems like Voicemeeter is not fully following the MIDI values I'm sending. I would greatly appreciate any help or suggestions to troubleshoot and resolve this issue. Thank you!

Where can I get the code??? The link in the bio is no longer working

The link of the code is not available now

MacOS Catalina demands for 64 bit Hairless Convertor. Is there any solution for this problem? Thank You.

helppp.... the cord works at ' debug ' after putting ATMEGA328 I got an error, 'MIDI' was not declared in this scope how to solve this error

there's someone who has the file of hairless? there no more avaible on the website

Thank you

Great vídeos and great ideias. A question: my Akai mini Play is USB Midi Port. My Korg Volca FMuses the old fashion five pins Midi Port. Do they have the same protocol and electric levels meaning that I can put both to "talk" using only a cable with different connectors? Thums Up and another subscription Carlos, Guarujá, SP

pow mano, bota a legenda pra português ai, to querendo montar meu primeiro midi, e seus vídeos tem ajudado muito... sei que vc é br então vai entender. tmj

Really nice videos, easy to understand, even for a French like me ^^ But the link for the code seems to be broken 😢

Hi! Thanks for the tutorial. I've used the code, hairless, and put all my settings the same as you, but my Arduino midi will not play in Ableton live. Any tips on what I should be looking for or any solutions?

what could I do when the HAIRLESS MIDI bridge doesn't have update for -macOS Monterey version 12.2.1 :/ ?? I din't find any alternative that would fork for my computer...any tips?

hi, great video thanks, great for drums and control, can we play the piano, chord sound or multi trigger?

Thanks for the great tutorial. The MIDI to Serial Bridge software is no longer supported for mac. is there any alternative software that i can use?

Hi, I have encountered problems with compiling the sketch. I have an Arduino Mega from ELEGOO and when I try to compile the program with my parameters, the following errors occur: Arduino:1.8.16 (Windows 10), Board:"Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)" C:\Users\*\Desktop\en-DIY_midi_controller\en-DIY_midi_controller.ino: In function 'void buttons()': en-DIY_midi_controller:143:1: error: 'MIDI' was not declared in this scope MIDI.sendNoteOn(note + i, 127, midiCh); // note, velocity, channel ^~~~ C:\Users\*\Desktop\en-DIY_midi_controller\en-DIY_midi_controller.ino:143:1: note: suggested alternative: 'MISO' MIDI.sendNoteOn(note + i, 127, midiCh); // note, velocity, channel ^~~~ MISO en-DIY_midi_controller:165:1: error: 'MIDI' was not declared in this scope MIDI.sendNoteOn(note + i, 0, midiCh); // note, velocity, channel ^~~~ C:\Users\*\Desktop\en-DIY_midi_controller\en-DIY_midi_controller.ino:165:1: note: suggested alternative: 'MISO' MIDI.sendNoteOn(note + i, 0, midiCh); // note, velocity, channel ^~~~ MISO C:\Users\*\Desktop\en-DIY_midi_controller\en-DIY_midi_controller.ino: In function 'void potentiometers()': en-DIY_midi_controller:220:1: error: 'MIDI' was not declared in this scope MIDI.sendControlChange(cc + i, midiCState[i], midiCh); // cc number, cc value, midi channel ^~~~ C:\Users\*\Desktop\en-DIY_midi_controller\en-DIY_midi_controller.ino:220:1: note: suggested alternative: 'MISO' MIDI.sendControlChange(cc + i, midiCState[i], midiCh); // cc number, cc value, midi channel ^~~~ MISO exit status 1 'MIDI' was not declared in this scope Thank you very much for your availability, beautiful project!

aye could you help me? i'm not using any pots only 4 buttons to switch profiles in my guitar amp software but the Analog is always sending data is there a way to disable pots? thank you if you respond :)

stuck on opening port in Hairless Midi. Any Ideas?

I'm using windows, I downloaded the LoopBe, I changed the output to it in Hairless and i made it the midi preferences in ableton but i'm not getting any sound out of it. I have the drumkit selected. I know the code is correct but i'm not getting anything out of the board. please help!

hairless-midiserial doesn't work with Monterey, does anybody know other ways?

Hi, i´m a first year electronics student university, and my first proyect is about midi controllers then is when I discovered you, i love your work! Over my research and encoding finally get my prototype, but still not tested whit a software.(hairless troubles) but my question is... if Im using hairless with arduino uno, can i use garageband instead of ableton? Hope you can answer me, im looking foward to get the knowledge and set up my first midi controller. Greeting from Chile, Great videos and very well explained.

HI gustavo! Nice job and thanks for share COuld you do something like this but with motorized faders?? THX

Will it work with GarageBand also?

Would i be able to close the Hairless MIDI to Serial Bridge after the setting up the first time? I want to use my midi foot controller with a multi effect guitar pedal. Do i need to buy Arduinos with ATMEGA32U4 chip?

This is crazeeei! I have one question monsieur, how to create a toggle switch on these buttons?

Help. Hairless Midi is not having a version for Mac any longer. Is there any alternative? Thanks!!!

I know I’m a few years late but I’m making one with piezo midi triggers. Anything I need to change (I’m planning on using 9 triggers) also how do you import sounds/samples for your controller

gah i got to the very end of this tutorial only to discover that the Hairless Midi to Serial Bridge is no longer supported by Mac! I've been scouring the net looking for an alternative but not coming up with much else... Anyone have any suggestions???

i am using atmega 328. if i leave the MIDI_CREATE_DEFAULT_INSTANCE function as a comment, arduino ide gives me an error like 'MIDI' was not declared in this scope. but if i make active the instance function , i see unreadable values like this :?< ?= ? on my serial monitor. does anyone know about this ?

Greetings and thanks for the knowledge. I can’t download the code, it redirects me to a page that says “this page isn’t live yet”. Can anyone help?

Many thanks for this. Quick question/comment about using Hairless Midi (12:50 in your video). Not sure if this is a feature of the Windows version but I don't see data coming from the Arduino unless I select a MIDI out in the Hairless Midi screen (e.g. LoopBe Internal Midi). Is that correct or am I missing something?

Does the button code work the same for key switches? I definitely will be getting your course! Musicians definitely need to be making their own controllers! Awesome job and thank you!

Ok but some pro micros require you to download sparkfun AVR library and you are not able to use the standard micro board. Would help if you added this.

Hi ! Do you know that we can't download the code ? It's written : This page isn't live yet If you are the owner of this domain you need to publish your site before you will see it here.

Top ! I discovered many things … so you can imagine a very big contrôleur for Ableton and control what you want ! However I want to know in the video about the midi fighter DIY the complete list of component to make this contrôler … Do you know where can I buy the box to make the midi fighter DIY thanks a lot

Is there any way to trick Live into thinking that controller is a control surface? So that it can be adaptive? (Like akai apc and the likes)... then i would dive into arduino Again 😅

Sir is there any way connect your this diy to WINDOWS

gr8 vid .. let me try my 1st arduino midi cotroller .. :)) but i want to make atleast 16 pontentiometre cotroller wtih 16 faders ... The thing is that i don't know how...:)

great video!! what about piezos?

I can't access the code???

In my serial monitor, only the buttons appear to be working. i use a different rotary potentiometer from the one in the vid, could it be the problem?

Top zeer goed uit gelegd bedankt

no code available... too bad

What changes I should make in your code for using multiplexer please help

Hey Gustavo, thanks a lot for this video. Apparently the link to your code doesn’t work any longer. Any chance you could re-upload it anywhere? Thank you!

Thanks for the excellent tutorial! While I patiently wait for my Teensy to arrive, I thought I would try to get things working on a MKR 1010 with the MIDIUSB branch. TL;DR: it compiled and uploaded fine, but no MIDI was generated. Uno version works great. Is there something obvious that I'm probably missing with an M0+ board that you can think of? Anyhow, I have signed up for the course and am excited to get started.

hi im getting errors in the hairless thing

teacher, the link of the code its down

If u use multiplexer like 74HC4051 how to change the code?

Im following everything but now Im stuck. If I define the DEBUG 1 I it shows great on the serial. Then when I change to ATMEGA328 I get a "MIDI was not declared" on line 220. Im new to the Arduino and have no idea what it means. In the meantime Im gonna google a little.........if someone has some pointers that would be great. Thanks in advance

Hi, someone had the code?

PLEASE tell me if I can recieve midi data from another controller with the teensy or leonardo or uno? I imagine so but how?

Can i use it with amplitube and how do you connect it to pc?
