Nice video! I'm in the process of building a similar enclosure. My plan is to do what you did here and also have a bunch of loops that i can select and have a physical pedal in each loop and therefore i could use different physical overdrives with different amp modelers/pluggins in my DAW. In your video you said at one point that in the code you use a bunch of if/else statements and that you would welcome alternatives to that... For that type of scenario it's often better to use a Switch (case) statement, the reason being the value of the "case" will be evaluated first and the branching will be made in regards to that, vs the if/else method, every statement will be evaluated in the order that they have been written until a match is found, so the last one would take more time to reach. If you choose to use a Switch statement, don't forget to include a break at the end of each case. the syntax would be something like this: switch (i) { case 0: digitalWrite(BU1LED, HIGH); digitalWrite(BU2LED, LOW); digitalWrite(BU3LED, LOW); digitalWrite(BU4LED, LOW); digitalWrite(BU5LED, LOW); digitalWrite(BU6LED, LOW); break; case 1: digitalWrite(BU1LED, LOW); digitalWrite(BU2LED, HIGH); digitalWrite(BU3LED, LOW); digitalWrite(BU4LED, LOW); digitalWrite(BU5LED, LOW); digitalWrite(BU6LED, LOW); break; (...) default: // statements break; }

Nice video, thanks for the content! For the input jacks reading garbage data when not connected, I would suggest using switched stereo jacks, this way the tip and ring can be both connected to ground when there's nothing plugged. I think that would solve the issue. Cheers!

BRUH, Thank you. I'm a tinkerer who just got back into playing guitar after about 10 years. I've been trying to find a way to use an expression pedal with my computer for my amp sims pedal boards and such, but all my options were adapter boxes that cost like 100 bucks, or a keyboard that'd take one over MIDI. I was worried this wouldn't do expression at first, so glad to see it does as well!

I like your Project and i have an idea for a small code-improvement. Define your LEDs as Array byte BU_LED[NUMBER_BUTTONS] = { 8, 9, 10, 11, 12, 13 }; In the setup make a loop for initalisier the LEDs: for (byte n = 0; n

Nice. I built mine to control PA600 arranger keyboard .16 buttins. 5 to select key signature. 7 chord changes (I,IV,V,II,ii,vi,iii) 4 rhythm variations, ending, fadeout, and inteo. I can sing and guitar while controlling backing tracks.

Can wait the project with add switch for bank selector, Cool project.

HI. This is a great project. I challenged this. I modified the source a bit and it worked with Zoom MS70 CDR. I stopped using LEDs. Because the second LED (D9) didn't light up. Zoom MS70CDR is equipped with a display, so it doesn't matter if you don't have an LED. Thanks for sharing this video.🤘

This looks awesome, I'm gonna have to try this, thank you!

This ia a really cool and interesting project. Thanks for taking the time to run through it. You give great crab! cheers mate

Awesome project. Thanks for sharing.

I loved!!! Great Job!

For all those who are new to this and really want a footswitch so that they can change effects and presets, here is a quick complete guide answering all your questions. What you need - 1. A box, it can be of plastic or metal( you can also use any old box that you have lying around, I used an old DTH box, removed everything from inside and saved up my money). Electric boxes like the Hammond one used in the video is rarely available in my country and I was hesitant to use a plastic box, so I went with the dusty old DTH box 2. A microcontroller - there are tons of microcontrollers out there, some are midi compliant while others are not. For example- The teensy LC is a midi class compliant microcontroller and can be used very easily, you can find the whole tutorial on KZfaq. However using the most common microcontroller like the Arduino Uno is also possible, you would have to run 2 applications (mentioned in the video) while using the footswitch that's it. The most difficult task was choosing the microcontroller for me in my journey of building the footswitch, because I was not able to figure out how to use my UNO for the project, but the code provided in the video is sufficient and directly copy pasting it in Arduino IDE works just fine. I put electrical tape on the exposed parts of UNO to avoid shorting of the components. 3. Buttons - In my country the stompbox SPST switches were not available, they had to be imported and it would cost me around 30 bucks for the switches alone, I used normal SPST Momentary Switch that students generally use for their science projects, it works perfectly but the only downside is that they are smaller than regular stompbox switches, it only cost me around 2.5 dollars for 5 switches. Wiring - You don't need to solder, it's optional, you can use hookup wire for the Daisy chain as mentioned in the video video or just use the breadboard wire, to join everything you can use gluegun to keep the wires in place. Only 3 things are required, the rest is optional but highly recommended. 4. An expression pedal - I had to buy and expression pedal for this project ( got the M- Audio expression pedal), it is a little costly in my country but there are several workarounds with volume pedals that are quite cheaper, and you can use a volume pedal as expression pedal in some cases, controlling various parameters other than volume. 5. Barrel Jack - there are two options- either go with the Marshall sized barrel jack ( which is only available in bulk quantities in my country, a single jack is again costly in my region) or go with a 3.5mm stereo jack module that would even cost less than a dollar. You can then use a 3.5mm male to 6.3mm female adaptor to make it work like a regular one. You can attach multiple jacks if you want by editing the code. However I have only used one. The whole project cost me around 25 bucks, where I also got the expression pedal. My friend had an uno and some wires lying around that he had no use for so I borrowed it from him. 6. LED's - Optional, I haven't used any led to keep my project simple and avoiding a bird's nest inside the box xD Now for the most important part, the footswitch can work with almost every daw out there like FL Studio, Ableton etc. Setting up your foot switch is easy and again you can find tutorials for it. For example I use Bias FX2 and Neural DSP, both support midi commanders and it's easy to set it up. It will also work with Amplitube and Guitar rig 6, no need to worry The footswitch can control any parameter that you assign it to, adding more switches increases the flexibility of use. My advise is to not buy midi footswitches ( or almost any other midi device that's out there, cause you can build them yourself and make it look as a retail unit) that go for around 100-150 US dollars, build one yourself it will only take you 2-3 hours to build one, my whole project got wrapped up in less than 25 dollars. Other MIDI devices- I'm a guitarist and I don't have an amp at all, I only have my audio interface with me and I use a 10w speaker for the audio output. Changing knobs on my software can be quite irritating sometimes, you can also build a midi controller to change the knobs by using potentiometers, the options are endless. It can look very difficult at first but trust me, once I made the footswitch work it gave me a sense of accomplishment and I got a idea of how Arduino works. I guess that I have covered as many issues that generally people face, if anyone has any other question they can ask me in the comments and I'll surely reply! Peace and good luck on nailing down your first Arduino project✌️

The expression pedal causing issue... You can get jack sockets that are switched, so that when you remove the jack it makes a connection. You could add that switch to another pin to turn it on and off

Super impressive

hey you gave me the idea to make little modules to turn my pedals on or off like the G Lab Uproar Fuzz does

I'm trying to build one strictly for punch in/out and return to start, just to keep my hands on the guitar. I hear those Teensy controllers are much easier, but I have Nanos and and Uno already so all I would need is the box/switches which are cheap. Anyway, great build and thanks for the rundown/code.

Amazing, thanks for sharing

Cool project!! I can't find the connection diagram, can you share it?

please help. I made all the connections and uploaded the code to the Arduino but my PC doesn't recognize it when I'm in Reaper.

Very good!!! 🔥 🔥 🔥

Thanks so Mutch

¿Is there any way to make it work with LEONARDO board?

What size resistors for the LED's did you use?

i want to build the same interface but without led lights and want to use 5 buttons using arduino uno, what should I edit in the code? (i have no coding experience)

Hi. I’m trying to do the same device. I use the LGT8F328P controller. This is an analogue of the Arduino Nano and the firmware sketch should fit. I built a prototype on your schematic, downloaded your archive, firmware uploaded to the microcontroler without problems or errors, but nothing worked. What version of MIDI_Library did you use? And how exactly do you connect your MIDI CRAB to your computer? I have a computer with Windows 10. I understand in order to make the device work to create a virtual midi port on the computer using software. I tried to use Serial_MIDI_Converter and loopMidi, but it didn’t work. Maybe I’m doing something wrong. I would be very happy if you would answer.

HI Nick good day tried to follow all steps provided on video, but after uploading the code to my arduino reaper/amplitube 5 cant detect or midi is not showing do you have any inputs for this? thank you!

Hi Nick!, this is awesome planning on building my own foot switch, question is what if I Decided to add expression pedal? do I need to buy a separate arduino?

what are the value of the resistors?

Brother please help me, I'm trying to make the same foot switch but without leds and I'll only use 5 buttons What should be my code? I've never done coding I'm using Arduino Uno with atmega328p

Hello bro I want aduno wiring diagram can you give Can you?🤟🤟

Hi, I hope you're very well, I have a doubt about this project, how did your PC reject the arduino as a midi device? i've loaded the sketch to the arduino but still doesn't recognize him as such. i'd appreciate any help you can give me. Thank you.

This might be a stupid question but can the uno board your using be substituted for the teensy 4.1

Hi, that is such a nice project! I dont wanna use the leds, so, just removing that part of the code would work? And I will use an esp32 as controller, if it works I’ll give feedback

Hello. It is a very nice project and very understandable. The computer does not see the Arduino Uno as a midi controller. I am using neural dsp plugin standalone. Can you help me?

hi Nick! excellent video ,its a very nice project! The footswitch is plug and play? How did you configure the controller so that it is a MIDI controller and is recognized in different software such as ableton? thank you very much!

hi mate, I have a noob question, does the enclosure need to be grounded as well? Or did you simply connect the various elements to Arduino's ground?

This is awesome, i need to try it. I was wondering your thoughts on adding more switches? Perhaps even double them, for Ableton looping purposes. Would you chain two arduinos or is there room in one for more switches?

Xcellent

hey everyone did i missed the wiring diagram?schematic wiring to midi port?

How long did it take to pick up all that fluff in the beginning? hehe Just found your channel, thankyou for all of your wisdom and knowledge :)

can we use it on multiprocessor effect (e.g nux mg300) thanks

works With Hx Stomp?

Thanks for a great video! I am inspired. Is it possible to send different MIDI CC messages in different MIDI channels by pushing just one switch?

Great stuff man, i'm planning of doing one of these for guitar playing with vst plugins. Are you connecting a normal expression pedal to the stereo jacks?

Hey! This video was so awesome it inspired me to make my own version in a similar vein, but for a slightly different purpose. I have some MIDI capable pedals on my pedalboard, but no way to control them with midi (without dropping ~$400 on something from morningstar or disaster area). I'm using an arduino uno just like with yours, but mine is going to send midi via the TX serial port to a TRS jack, instead of sending midi via the USB port. This is my first project like this, and I've spent a lot of time coding the software which I'm now more than comfortable with, but what I'm not familiar with is the wiring part of this project. I've never wired anything up to an arduino before and I'm not sure when/where resistors are necessary. I know from your video that you need them for LEDs, and it seems as though you didn't need to use any for your foot-switches, but will I need to use a resistor for the TRS expression pedal jack or for the TRS midi jack? I've scoured the internet for answers but this topic seems far too niche for me to get any reliable results. I was hoping maybe you could answer these questions for me since you've done almost exactly what I'm doing. Or even better, how does one know when to use a resistor in general? Is there some rule I can use to know when/when not to use a resistor in an arduino circuit? Thank you so much for making this awesome video and inspiring me to make something of my own. Any help is greatly appreciated!

I have watched several tutorials on making midi stomp boxes, and I have one kinda weird question: Why are you all using breadboard wire instead of getting regular wire and soldering everything? It makes no sense man...
