Arduino MIDI Controller: Part 1 - Potentiometers 

Man, I can't tell you how valuable ALL of your videos are! I appreciate how orderly your breadboard work is. It makes it much, much, much easier to follow and copy. It soothes the OCD in me. Wanted to say thanks!

You just convinced me to going in arduino diy project. Perfect videos, even a noob as me now can try :)

Arduino -> Pure Data -> Loop MIDI -> MIDI OX -> You got it ! :d *edit* The arduino patch that is needed is the "Standard Firmata", you can find it in the core libraries

Man this vid is a life saver ,upload the push button part asap ,gotta finish up a midi controller which i have waited through out my entire life ..............................PLEASE NOTES AND VOLTS UPLOAD THE PUSH BUTTON TUTORIAL ASAP

Best tutorial on RU-vid, I'll make a mod and pitch wheel for my old Casio keyboard.

Your tutorials are SO on point! Thanks! I took a mini course about arduino and I felt in love with it and I'm willing to buy my first kit in the next few weeks. Your channel is a gold mine to people who are primaly interest in music things and want to give the first steps without being overwhelmed in the beginning by all the electronic and eletric stuff that fill tons of pages in manuals! I saw some cool ideas about sequencers, but being a totally dummie in arduinos, the videos that I saw didn't covered with such details as yours. I'm just suggesting that would be awesome if you made some project that can sequence samples, or even synth sounds. Thanks for sharing your knowledge!

5:58 - 6:29 you saved my life:)

This is really helpful, I might make something like this to add some more knobs to my microkorg

Upon finishing the Arduino MIDI project, I have it without the MIDI connector; it's directly connected via the USB cable from the Arduino for the connection. It provides the values that are reflected, but in the DAW Reaper that I use, it doesn't recognize them for assignment, as turning the potentiometer doesn't assign a value.

wow , man...youre sooo clear and simple to explain , its impossible dont understand, thank you so much and congratulations.

This is exactly what I was looking for. Planning to adapt this into a eurorack module.

Thanks mate! Fantastic tut, really clear and well explained. Fun project!

Well done, thanks so much, I will get started as soon as my part orders delivered, thanks for sharing 🥰👍

Beautiful tutorial! This is a master class on making electronic controllers and midi instruments. Thank you!

FANTASTIC for a MiniMoog (Arturia) MIDI control... many Thanks

The best Arduino/MIDI tut. Thanks!

What a great video! Thank you for your attention to very clear and concise details, with no extraneous static - a gem!

Absolutely great video - very informative for non-professionals - thank you very much.

5:46 you can use the MAP() function which takes 5 parameters exemple: (myPot, 0,1023, 0 , 127)

Awesome stuff thanks Dave. I had trouble getting this working, pots working fine, tested them separately. I went to the MIDI output tutorial and in that one you recommend to disconnect the wire coming from the TX pin on the Arduino while uploading the code. I was leaving it connected before and I guess that was the problem because now it works great.

hey man just wanted to say thanx for this. i built a midi controlled wah with this that i can run with my hand cuz i got 2 bum legs and can't work a traditional one...now i just need to figure out how to get all this stuff in a lil box that i can put on my guitar. :D

Fantastic tutorial Dave ...Very well presented and clear descriptions of the process.....Well done mate :)

Another great video from notesandvolts; love your work man

Is there any way to change the midi socket to a USB printer socket?

Is there a way to directly use USB as MIDI instead of the MIDI jack?

The main requirement to make it work is the data, which we need to upload in to Arduino, I wish you provided the exact link 😉

Thanks Dave, your Arduino - Midi videos are very informative !

What's the maximum number of pots that can be used?

Awesome!!! I was able to create a multi-channel 3-D MIDI control using joysticks to control the 3-D pan of live surround sound systems! Thanks a lot for your work, programming isn't my strength!

Hi, Great video. I have tried this project, but the Arduino nano's TX led is continuously lights up. When I use a button on pin 2 to send note on/off messages it works fine, and the TX led is only lights up on pressing and releasing button, my midi Synth also playing the note, but with potentiometer there is no change. I have tested analogue read program to see if there is noise in adc reading but the readings are stable. I have changed the analogue pins from A0 to A7 but the result is the same? Please help me to sort this out, please give me a reply.

Hi, could you explain the difference between using 10k and for example 100k potentiometers. I mean what effect will I get using the 100k potentiometer and what 10k. What is the best resistance for potentiometers in midi controllers. Thanks in advance. Good job!

Hi, this video is marvelous and the way you explain is perfect, and I want to try but I'm new with Arduino. I know that this was in 2016 and I want to know if there are an updated version, or I can use the Arduino One that is available today. Saludos desde Buenos Aires.

it is sooooooo well explained it is mindblowing

The pot works until it is left alone for 2seconds; it stops sending any midi, unitl the unit is reset.. Any ideas?

Can not I use the usb port instead of the midi jack?

Is it possible to send the midi signal back out of the USB connection instead of down the MIDI port?

Do you have a favorite model of rotary and linear potentiometers for midi controllers?

why midi jack .. can we use it as DAW controller without the midi jack ...

How many potentiometers can you have with Arduino UNO? only 6?

Should the potentiometers still be connected the same if I don't use a midi jack?

Hi. I am a beginner. Can somebody say me whats the examen name of the "midi module" for buy it ? Thanks.

From where the circuit gets 5 V power. There is no separate power source shown in the circuit

I tried this and used just two pots, the pots are used at foot expression pedals (10k Linear each) when it's set to just one it works perfectly but when I add the second pot the midi info in OX just keeps scrolling, even when the foot pedal is not even plugged in. Also if it is just set to use one pot and I plug the foot controller into the second pot socket it still recognises something is plugged in and keeps scrolling, what's going on here then?!

hello, can you give me a simple way to code CC midi on a potentiometer, I have tried various methods but have not succeeded, please. thank you

Great! Thanks! What about encoders (infinite pots) and motorized faders? Would be great to have such video. I started (and already freezed) a project couple months ago making something like Mackie MCU (or any other control surface) with Arduino. Their price is very high and it would be great to have such video on this subject as everybody would want to make something similar at home for their home studio. Thanks again for such useful video.

I just get -"Pot" does not name a type-... when checking the code.. when researching aparently the Uno does not support the midi library, but it is obviously being used in this example.. not quite sure whats going on..

Hi your project is very nice and instracable, i try your project but when complle coad gatting error "update button was not declard in this scope".what is problem.pless can halp me.

Thank you for these videos!

but can't we use the (127./1023.)*potval for a super accurate answer instead of 1023/8. potval is the value coming from potentiometers (127./1023.)*1023 = 127 (127./1023.)*511.5 = 63.5 (127./1023.)*0 = 0

can i use more than 40 faders and pots

Could I possibly build this kind of thing but for 1 single pot that I can install on a guitar?

I have two pots set up, PO1 and PO2. I have tried them on different pins, A0 thru A5) but no matter how I connect it, one pot will trigger both control changes at once. no matter which pot I use, or even if I only wire one of them up. Any idea what to look for?

I need a MIDI CC expression controller in a foot pedal - I searched eBay and Google high and low, nothing. I do however have an Arduino and an old wah pedal, hmmm...

It may be a basic question/answer, but why do we attach the 220Ohm resistor between the transmit on the Arduion and Pin 5 on the MIDI port? Is this similar to adding the 4.7K between Pin 7 on the 6N138 to help discharge capacitive charges?

Can you do Midi and CV (or just CV) tutorial with Arduino? :D!!!!

in my case it works perfect until I put the potentiometer number 4, it sends constantly midi signals although I do not want, could someone help me ?.

Hi, What about banks with pots or buttons in this code.

GREAT TUTORIAL !! Thanxs for your info!!

Great! How can I use these potentiometers to send MIDI Sysex?

Thank you very much!!

after program upload in when i use pot seial monitor show ?????????????????;;???``// something like this what i can to do?

great project

Love your tutorials on the builds, got some stuff on the way to make me a diy midi to go along with some of my other projects, but would I be able to make the diy controller Bluetooth?

There is a fonction called map() that remap a port , map(A0, 0, 127)... 😉

Hello! This might not be the best place to ask for support but I've started having problems with this project recently. I've updated my system recently and have now found that the midi controller built with this code doesn't work anymore. My computer and DAW recognise the USB midi cable coming from the project and the light indicating that there is CC going through the cable is blinking when I turn controls yet none are reaching my DAW. I have also tried switching cables but I just came to the same result. Have there been any cases like this before? I haven't tried reuploading the code yet but that shouldn't really affect anything since nothing changes in the code right? Worked amazing before though and the code has sparked some really great projects for me.

the red connector is midi to usb connector right ?

Hi, Is there anybody has tried connect this to DAW software via USB MIDI cable? I have connected it by USB MIDI cable. The MIDI cc signal became none continued, CC signal only transmit one data each time I turn the knob. But it worked correctly when I connect it to my Synthsizer. I want to use it to control my able tone live. Is there any suggestion to connect PC which has no MIDI port? I mentioned USB MIDI cable that is I bought it from China. The cable is USB to MIDI 5pin. I connected the 5 pin MIDI to the Arsuino. The USB to my computer.

Amazing tutorials!! Thanks!

Fantastic, would this work on a Tinsee 2?

Firstly, great video! Extremely helpful and clear. Secondly, has anyone tried using different potentiometer values such as 100k? Are there any significant changes and do you need to adjust the code?

hi... I saw some midi instruments have 2 midi jacks, and this one has one midi jack. can I use only one jack, can you explain why ,or suggest a yt video for me, can you? also your tutorial videos are nice

Great tutorial - anyway to turn this into a midi out on USB?

i guess i can't just use the arduino usb connection for the midi output? i'm getting unreadable outputs in the console and there is no midi device being recognized. i wanted to use this to change values of my DAW on the fly.

This video is perfect! Is there any way we can send pitch bend message through pots? I am trying to make a control surface using MCU protocol, and it requires pitch bend messages to be sent for controlling faders in the DAW.

YEA ! :D I see the code is full of nice features :D ... waiting for next videos :)

Don't you want a small value capacitor to decouple the midi jack? Some midi devices don't play nicely and could burn out the uno.

Hi, having trouble with this one. Still not transmitting any data. Compiling and uploading fine, Triple checked wiring, midi jack sends data to PC with a regular midi keyboard, but not from the arduino.... A bit stumped...

Hey! I wonder why do you have to make these signals MIDI CC? Wouldnt it also be recognized by DAWs if you connect the circuit with the Arduino via USB?

can you do the same with an arduino duemilanove?

I'm guessing that shifting bits right by 3 and left by 3 is to mask the lower 3 bits? _value = analogRead(_pin); _value = _value >> 3; _oldValue = _value

Amazing, thank you so much, extremely well explained. :)

I can send midi signals with pot1 but I am reading "timing clock", "PC: Trumpet", "PC: FX 7 (echoes)" etc. in MIDI-OX (event section) What is the problem?

If i want a 32 knobs midi controller the procedure Is the same?

Can I have false readings with arduino supplying low amount of current to handle 8 pots?

HOW MANY KNOBS COULD YOU CONTROL USING ONE ARDUINO BOARD? IS IT POSSIBLE TO HAVE A LOT MORE INPUTS SOMEHOW OR DO THE BOARD PINS REPRESENT THE LIMIT (1 PER PIN?)?

No opto isolator?

how to make usb midi controller

I have tried this project several times (I'm a noob) and can't get the compiler to finish. Lots of errors. Can someone help me?

Thank you very much for theses videos. I have learnt a significant amount and have watched many of your videos. How does one go about adding a switch to this project to enable the ability to swap MIDI channels? (specifically, using an external Arduino like the older model - Dueminalove)

thank you for the tutorial, i would like to build a project like this but with 8 pots, i have an arduino uno like yours, how can i do it?

Great video thank you, i would like to take example for a flight simulator application. What is the limit of potentiometers and buttons that can be added to an arduino? thank you so much. Marco

Is there a way to controll more than one CC with one potentiometer?

what is that midi jack for when there is a usb port?

Hello, I am writing to you from Argentina. I want to know what is the interface you use to connect Arduino with computer? Do you have or can you make a video on that? I want to make a DJ controller for the MIXXX open source software and I'm seeing it step by step but I find that you use a MIDI port and these controllers use USB.

Thanks so much, very helpful

so i'm still working on my wah wah thing. i found adding a 10k static resistor between the middle pin to gound and the analog pin keeps the voltage from bouncing around. i have no idea why this works lol. thanx again dave! :D

I know this is acient, but, if someone sees this please help. I basically want to make a surface with like 16 potentiometers. I want to be able to map them to anything in my daw. What CC should i put in. I dont want them to have just one function, i want to for example use 1 knob for attack in one plugin, and in another one i want it to be for delay. How?

I have a Problem!? I will upload the Code but they don``t will this. They say me: We find more Libararys for Midi. Why i Have the Midi Libarary Master / I have the Midi Libarary / and another Midi, but not works why

Hello, this mod worked better for me, since it works on any track selected, I have 8 sliders and had assigned them to 1-8, but can’t do anything to tracks 8 and over, I thought it could move like scenes, 1-8, 9-16, 17-24 etc, but couldn’t make it work, any suggestions? Thanks.

8:50 With the software I downloaded from Notes & Volts the line of code you highlight is commented out, gotta delete the "//"
