#3 Build a MIDI controller with an Arduino: The DIY MIDI Controller Workshop 2.0 

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!

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

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

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

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

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

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

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..

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.

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

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?

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

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 It says its out of date.

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

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

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!

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

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

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

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 :)

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

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.

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?

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.

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

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

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 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?

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

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!

Very catching! Thank You. Going to repeat it.

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

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

Show de bola 👏 👏👏👏 Se colocar piezos eletrônico no lugar dos botoes, funciona normalmente ? A indeia seria usar esse projeto para uma bateria eletrica

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

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?

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?

The link for the code is not working :C

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?

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

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.

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!

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!

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!

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

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

what midi library should i install for mega16u2 ?

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?

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

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

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

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

Nao consigo abrir a pagina onde transfere o código! e preciso urgente para trabalho da faculdade 😥😥

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

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?

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

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!

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

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.

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

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

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?

What happens if i have big sur? Cant use hairless

outra coisa, consigo usar o arduino nano pra montar meu midi? ele tem tudo do arduino uno e tem mais portas analógicas

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?

Will it work with GarageBand also?

thanks for these series ♥♥♥

cool video! but I have a question. I want to get rid of third-party serial-midi conversion software on my computer. So that arduino is immediately recognized as a midi controller. Tell us more about this? is it possible to flash the microcontroller so that it immediately imitates a midi device?

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

If we are using a serial to midi software then why to use a midi library in arduino code ? Cant we just write a normal code which will show that serial output and then use that software to convert it into midi ?

Gostaria de tirar uma duvida seria possivel eu controlar o voluma do windows com ele? por exemplo , um apenas para o jogo, discord, internet e spotfy?

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???

The link of the code is not available now

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

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 ?

Hi thank you for the wonderful tutorial, this is exactly what I was looking for! I'm almost there, just have one "last" problem to overcome. Hairless keeps giving me error messages such as "+2.951 - Error: got unexpected data byte 0xa." I used your code and made only the mentioned adapations (Windows 10, Arduino Uno, LoopBe1). Gustavo do you have any idea what the problem could be? I would appreciate any help or tip :)

Where can I find the code? The link keeps sending me to sign up page

I'm trying to use MEGA2560 but which MIDI file should I install? It compiles fine but when testing via serial monitor button/pots spit out random symbols like "ݨ⸮ة⸮i⸮⸮⸮⸮⸮⸮"

Hi! Thank you for the tutorials. Where can I download the code? The link seems broken. Thanks!

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

it is fantastic!!! one Question: Can I use an expression pedal as a potentiometers? I wired it up like if it was a potentiometer, in fact it is, but the behaviour is erratic. it only goes from 87 to 127.

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

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 😅

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 im getting errors in the hairless thing

The code link isn't working or there is a problem with the website

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...:)

Hey man, I'm stuck for way to long now with the same issue.. as soon as I ad more than 4 potentiometers to the code, the serial monitor goes nuts an recieves random MIDI Data from all the potentiometers above A3 (in my case A4 to A15), from 0-127 all 0.01 seconds. If I'm only working with three knobs, everything is working just fine.. Do you have any idea what the problem could be? Cheers mate! :)

hey man, I want to change the code a bit so I can make a studiocontroller over midi (so mapping some monitoring plugins to control over midi). How can I change the output to midi cc and how would you fix it so the button would save the state upon next press (making it a on/off switch). Cheers for the vids, loving them!

This was so helpful! Thank you man ❤️

Is the Arduino Starter Kit still available for purchase?

Great teacher!! thanks Gustavo

sir i have followed each step my Debug is working bur ATMEGA328 is giving error in line 241 as MIDI was not declared in this scope please help

stuck on opening port in Hairless Midi. Any Ideas?

hey im getting a problem whit the code and i dont know why, it says that at line 220 MIDI was not declared in this scope, can anybody help me?
