Soooo, I'm at my friends home and we just tested the midi through with his trusted equipment. It doesn't work. I'm going to contact Lowtoy and see what they can do about it. I'm not an a-hole, but I paid for a fully working product, so I think it's their job to fix it. If they can give me some help, i would fix it myself, but I'm not an electrician expert.


I got my own midi keyboard and tried it. funny thing is, when i pluged it in, nothing worked. then i turn an ecoder on my keyboard and suddenly, the red status LED light up. and now, midi in does work, but midi out doesn't. i tested it with mGB btw.

does the arduinoboy/mGB software needs some special midi CC command or anything like that to start?

another funny thing, when i first tried it only with my interface, nothing worked. now, with the interface, midi in does work, sound comes out of the gameboy, bu the red status LED doesn't light up.

I just don't understand it.

ahh men. seriously? Is it just a batch or are all of their pcb's faulty?

Both Midi out and in doesn't work. I connected the Gameboy with LSDJ as Master and with mGB.

Unfortunately, i only have my USB interface, no keyboard or synth to check the midi circuit. Afaik, the midi out is also a midi through, so with a keyboard and my interface, i should at least be able to check the midi circuit, right?

asap, i'll go to a friend of mine, who has more midi stuff and also a continuity tester. it just would be awesome to be able to get it work by myself without the need to drive an hour, but...yeah.

i used a DMG 007 cable with the same result, it doesn't work.

it is wired:
blue - ground
green - A0
yellow - A1
red - A2

brown and blank are not connected.

thing is, the LED also blink in sync with the tempo, when i use LSDJ in master mode.

Okay, i can check them when i got to a friend of mine, he has a continuity tester. I also have a spare LSDJ keyboard cable. I did use a DMG-007 cable to make it, so I can desolder it and use it for the arduinoboy.

edit: anyway, i keep you guys updated. I really appreciated your help smile

no, I'm using the DMG-004 cable. the black one. but i can get a DMG-007 cable smile

can someone at least confirm that the blinking of the LED's does mean that the arduinoboy is behaving normal?

i use all channel. but i also tried channel 1-4. same results.

here's a screenshot of the wiring of the link cable:

Hey, i got a strange problem with midi.

I use an arduino uno with the lowtoy midi shield. it's powered via usb.

mode switching does work i guess. when i press the button, the LED for the mode does blink, when i press the button when i'm at the last mode, lsdj slave master and the status LED blink, another press, all LED blink, another press, i can cycle again. the status LED isn't always on, though.

when i'm in lsdj master mode, the led do blink in sync with the beat.

the link cable is connected like this:
i don't have a multimeter to check the wiring.

problem is, mGB and LSDJ don't get midi signals. i only have my focusrite saffire 6 usb interface and cubase, no midi keyboard or other stuff. and I'm almost noob to midi stuff.

midi wiring is:
focusrite midi out ----> midi in shield.

I made some screenshots of cubase:

Hope you can help me out smile

btw, a friend of mine does have more midi equipment, but i want to check first that everything is connected the right way.

2 in / 4 out USB audio interface


http://us.focusrite.com/usb-audio-inter … ifications

Ease of Use

Pretty straightforward. Check senstivity, check if you need phantom power. Plug in and go.


I got mine used for 100 Euro in a new condition. Should be no problem the get i via Ebay for something like 129 Dollar new or cheaper used.


Don't think that it is still in production.


Smooth potis, buttons do a a little quiet click sound when pressed. Metal enclosure, sockets for midi, audio etc. are unfortunately direct soldered to the board. But so far, no problems with that. Comes with plastic pads, u should use them. otherwise it will slip easily over the table.

Sound Quality

No Problems with noise, distortion etc. It's my first real interface, i had a tascam us-122 mk1 which was really sh** compared to the focusrite.
The Interface won a user sound blind test made by the german site musotalk.de with competitors like Motu Ultralite MK3, RME Fireface, Metric Halo ULN8. Here's a link to the test:
http://www.musotalk.de/video/audio-inte … dhoertest/


I just love the minimal design. All you need is directly accesable via the interface. There's no software mixer, but u can change buffer size and resolution in a software panel. Smooth metal enclosure, no sharp edges. Looks very profesionell, LED's are not too bright.


Not really large, not heavy but also not really lightweight.
W = 220 mm / 8 ¾", H = 45 mm / 1 ¾" , D = 145 mm / 5 ¾"
1 kg / 2.2 lbs


Power via USB, fits in a small pocket. Be carefull with the Potis, they stand out a little bit. No external power adapter.




Midi in and Out, no external Sync option.


USB Device, drivers are needed but up to date (osx 10,5 and windows 7, don't know if it works with Win8) last driver update was march 27 this year, when i wrote this post.


Only 1 Midi in and Out, no CV no external SYNC.

Ease of Modification


Personal Experiences

I have this one for a half of a year. I had some little trouble installing the drivers, i choosed the USB 2.0 Option but it didn't work. So i send a mail to the Focusrite Support. After an hour, i allready got an answer. The support was really helpfull but i allready figured out how to get it worked, i choosed the USB 1.0 driver option. The device is "only" USB 1.0 so it didn't matter.

I use it for chiptune and for direct guitar recording. Absolutly zero problems with audio and midi, it works like a charm. I wanted a simple, portable and sturdy interface with good preamps and i just got what i asked for. I love the fact that there's no software mixer so there's no need to togle to the cubase window and back to the software mixer and back to the cubase window...

I only use it at home, but i wouldn't be afraid use it live.


Lots of bang for little money. Only 2 channel input and only 1 Midi In/Out but if that's enough for you, get it!


- Sturdy design
- Good preamps
- Great support
- drivers are up to date
- (almost everything accesable via the interface)


- Sockets direct soldered to the board
- Only small plastic pads, if you don't use them, very slippery on the table
- (no software mixer)

this one is great:

Okay, I'll check that out.

But the point is that mode switching still doesn't work, and the red led is always off, no matter what i do. it is correct soldered, i checked it with a blink programm.

the red led is always on, right? so why is it off on my arduinoboy? i just don't understand it...


(4 replies, posted in Nintendo Handhelds)


I also checked if the arduino is working correctly. I uploaded the basic blink programm and the Led is blinking. I changed the code to check the other Led's and they also work.

I bought a second arduino nano from the same seller, and i did this little "synth" with sucess:

So I'm pretty sure it's not the Arduino which isn't working, it must be something else.

Is there any option to check the working of the button? a simple code or something like that would help me.

I also do not need all those modes like LSDJ out, I only need mGB so is it possible to upload only the mGB Part of the Code? Will it work then?

Hey, I just finishes building my first Arduinoboy. I think i did an okay soldering job, i checked the wireing twice to make sure that i connected everything right.

Midi In and Thru IS working. i checked it with a synth and a keyboard.

mGB doesn't get the "midi" signals.

After the Startup, the LED's are blinking in an almost random order, after that, they all stay black, including the red LED. Then after a short period of time, they continue to start blinking again, then they stay black. then after the same period of time, blinking again. and so one. The blinking and the time when the led stays off after the startup seem to follow a pattern.

Strangest Thing:
I use a non powered link cable, direct soldered to the pins of the arduino. The arduino gets power via usb, it's an arduino nano. But i after i disconnected it from the USB power source, it stays on Oo. When it is connected to the USB, the Power LED of the arduino is on. When i disconnect it from the USB power and leave it to the Gameboy, the RX and TX LED on the Arduino are blinking.

Hope you can help me out smile

NO I'm certainly NOT trolling, I'm just sitting here and desperately trying to figure out why there are 2,7k ohm resistors metioned in trash80's shematic, that's all!
