    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 🙏🏼

    THX for the video. Easy & fast way for DIY MIDI, also cheap.

    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

    Boa noite amigo. Já tem alguns meses que estou tentando usar o Arduino uno pra fazer um octapad para meu filho de 12 anos que é baterista. Mas não consigo fazer o Arduino controlar midi no maços. Em outros videos mais antigos VC até mostra como usando o hairless midi. Mas não consigo mais instalar no maços Monterey. Tem alguma dica? Queria que o Arduino uno que tenho em mãos, controlasse o kontakt

    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

    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?

    Does the resistance of a poti matter in that case?

    • @NerdMusician
      @NerdMusician  7 місяців тому +1

      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.

    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
      @NerdMusician  Рік тому

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

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

    • @timeubank4687
      @timeubank4687 10 місяців тому

      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.

      @@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
      @chrisw1462 10 місяців тому

      @@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).
