USB Midi Controller for the ZOOM G3 (v.0.02a)

ZOOM G3 Guitar Multi Effect
Arduino UNO
USB Host Shield v2
LCD & Keypad Shield
(OK you should have an electric guitar too, for full delight!)
ZOOM G3 can respond to program change MIDI messages.
It changes the patch.
You can change the patch via keys etc.
After some researching, it's possible to send/receive MIDI over USB, using USB Host Shield v2.0.
All you have to do is to construct and send a 2-byte message.
Sample arduino code:
byte Message[2];
Message[0] =: 0xC0 // (Program Change);
Message[1] = (byte)map(analogRead(PotensiometerPin),0,1023,0,99);
Midi.SendData(Message);;

Μπράβο, Αντώνη, ανήσυχος όπως πάντα. Καιρό έχουμε να τα πούμε.
Χριστόδουλος, Δράμα.

Χρόνια και ζαμάνια!!!

Great Video, i have 0 knowledge about arduino but you have encouraged me to learn it! i want to make a 2 switches controller so i can go up and down between patches in the looper mode.
any advices?

[@ocangalanocang8758]

can use to all ZOOM effect?

Should I be careful to connect usb host to g1on or just may I plug and try?

[@hubertwouts]

hi how can i use this code too use with an old school midi output ? should ik just include midi.h and start the baudrate at 31250 ?

[@hupur]

so could I hook a behringer fcb1010 pedal to the arduino and control my g3 with it?

[@hupur]

ZOOM G3 responds only to Program Change................if that's true how is it thatI can change effects and volumes and parameters with the edit and share program and it makes the zoom change in realtime..it must be sending cc's or sysex or something

[@alessiogagliardi4436]

Thanks for the source code, but unfortunately I got an error like " 'MIDI' does not name a type ". Could you please help me to solve it? I already added the USB Host Shield 2.0 Library, but it seems that some lib is missing. Thanks in advance.

[@Stoo426]

I don't know whether you ever got anywhere with this, but I've just come across the same error.... I fixed it on mine by changing the line "MIDI Midi(&Usb);" to "USBH_MIDI Midi(&Usb);". I'm guessing the library got updated at some point to avoid naming clashes maybe? Not really sure, but either way it's working for me now!

[@jedarroyo8157]

Is it possible to make a foot switch that will let me scroll through the 6 effects? Is that possible with arduino?

[@tetsu83]

Any updates if this will work on a G3 with v2.0 firmware?

[@maglaras]

Jero Joseph Pura It works with v2.

[@MarcosCosta-mn8gg]

Hello which the value of the resistors ?

[@rimaraerrazan5239]

Thats cool ..you can actually make a midi controller made specially for zoom g3x and b3x... Could you make a tutorial on how to build that midi controller? Or the small devices can be get to electronic shop as it is?

[@maglaras]

You can build yourself one.
Take a look here:

[@rudsonsm]

Gostaria de montar um para MS 50 pode me ajudar ?

[@LorisEmanuelCianni]

This is great. Can you make a tutorial to use a midi pedalboard?

[@LorisEmanuelCianni]

Antonis Maglaras I have yet a midi pedalboard. Do i must to copy the usb-midi library in libraries directory and it works?

[@56335130]

they just dont want us to use the godgivingmusicianbestgift MIDI,the digitech rp 100000 ,the zoom g5000000,g300000000000,the korg stomp/amp lab(a lab with out a essential tool mini wtf) ,what's going on with the multistomp factory.

[@MarcosCosta-mn8gg]

Can I use this controller in Zoom G5n?

[@maglaras]

I really don't know but my guess is yeap :)

[@BogdanCatanoiu]

schematic for this controller, please.

[@maglaras]

+Bogdan Catanoiu Everything is on video's decription. It's an Arduino with a USB host shield and a LCD keypad.

[@BogdanCatanoiu]

Can you tell the LCD/keypad shield where to buy from ? or at least the pins of the kepad switches

[@maglaras]

+Bogdan Catanoiu Take a look at the code: github.com/vegos/ArduinoMIDI
They are all documentaded.

[@BogdanCatanoiu]

Thank you, I found the info I need.
