Arduino MIDI Controller: Part 1 - Potentiometers

Build a MIDI Controller with your Arduino. In this video we will focus on Potentiometers.

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.

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.

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

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!

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

[corvokenway.]

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

[JonasHamill]

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

[bio]

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

[ruhsuzat]

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

[daddydanny]

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

[mathias]

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

[jacouys]

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

[josh.graham]

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

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?

Its not a "MIDI Jack", its a '5-pin DIN socket' - They where popular on hifi in the 70's, Christ alone knows whay as they sound awful!

[jefferyrussell]

For some reason your code no longer works. Perhaps it needs updating as this project is 4, going on 5, years old. I've tried this over a half dozen times now with no luck. I'm going to look for some alternate code elsewhere. BUMMER!

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.

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

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...

[TheOriginalJarvees]

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?
