In this video, I'll give you a complete guide on how to code potentiometers to send MIDI with your Arduino, so you can build your DIY MIDI controller.
I'll cover many important topics, such as analogWrite(), analogRead(), how to wire potentiometers, how to use the ResponsiveAnalogRead library to get a smooth reading, etc.
Also, you'll learn how to send MIDI Control Change using the MIDIUSB library, which allows your Arduino to become a MIDI class-compliant device.
This is a full programming course condensed into a class!

Thank you so much! With your help and all your content I was able to start working on my first midi controller for my Tibetan bowls project with a captive touch sensor. So many tips in your videos! I'm really very grateful to you 🙏🏼

Just found this video series and I'm very impressed honestly. Will you add something on adding multiplexers as I'm rather confused as how to do that!

Im trying to build a controlller for Rekordbox but is doesn't seem to register the controller. Am i doing something wrong or doesnt rekordbox allow custom controllers? *edit* the controller is gonna be a add-on to a DDJ-FLX4

@DanTechGA 4 ай бұрын

I'm having an issue at compiling in the loop. I get ""controlChange" was not declared in this scope." Any idea why? I love the video, but I'm stuck!

i connected 8 potentiometer to a 16 channel mux, how to code for that

@pulsmond 8 ай бұрын

Help me figure it out: Ableton Live does not see the connected controller before launching Ableton. If I turned on the controller after starting Ableton - everything is fine, everything works. Why is that?

@andreasfurxer4135 6 ай бұрын

Hello, I am using an Arduino Leonardo, and I have installed 4 potentiometers and 3 buttons, adapting the code accordingly. Everything works smoothly so far. However, the potentiometers do not behave as I would have liked. Unfortunately, the control range of the potentiometers is very short. When I set the potentiometer to about 60 percent, the MIDI value is already at 128. I am using a 10K fader as a potentiometer (128mm). Is there any way to adjust this control range? Best regards from Austria, Andi

Does the resistance of a poti matter in that case?

@NerdMusician 3 ай бұрын

It matters more if you use different values, because it will give you different curves, but just stick from 5-20Oohms. 10Ohoms is ths standard.

0, 127 (128 states) ...not 0,128 ...because 0-128 is 129 which not 8 bit but 8bit + 1

If I couldn't move a CC knob very fine, I'd get rid of the MIDI controller. Your 'threshold' and timer is way too much compensation.

@NerdMusician 10 ай бұрын

With this "compensation" I get VERY fine readings. That's how it's done!

@merumerutho 8 ай бұрын

Place a capacitor between potentiometer output and ground. It acts as a low pass filter and removes the noise.

@timeubank4687 5 ай бұрын

The problem is MIDI. you only get 128 values. there are no decimals. I'm not sure what you would replace a midi controller with to execute midi commands. Getting a multi turn pot that allows fine precision won't do you any good to turn it 6 times to go from 0 to 1, you can get 0 to 1 with any Kb pot just fine.

@chrisw1462 5 ай бұрын

@@timeubank4687 When I said I'd get rid of it, I meant because it was malfunctioning. You'd replace it with one that works as it should.

@chrisw1462 5 ай бұрын

@@NerdMusician The problem with the code is using the built-in map() function _before_ compensating for changes. Compensating _after_ map(), loses resolution and some control. If, instead, you use a hysteresis function before map(), you can keep the resolution and get even finer control. The ADC read function would save the last reading and compare it to the current one. Then, if and only if the value has changed more than 3 or 4, you call map() and MIDIstate() to see if the MIDI value needs to change. (If it's less, throw out the new reading and keep the old one.) Tune the comparison value (3 or 4) until you are happy with the control. Of course, @merumerutho's suggestion of adding a small capacitor across the potentiometer would also help - both the cap and the code change would make it very stable. A 100 nF (0.1 uF) cap is enough, and should help with local electric field changes, too (no value changes just because you moved your hand).
