Does the mGB mode on arduinoboy accept MIDI CC data from the keyboard it is connected to? I need to crack open the code once I get home...if it does, it should be easy enough to modify it to accept the cc values from the i/o pins/pots

Ah! Good point, I'll take a look. Thanks!

Sure, I believe that's basically what I'd like to do. However, I'd rather not buy it...I've got a working arduinoboy, and I like building stuff

I was browsing around and couldn't find a whole lot on this, one or two threads with speculation and ideas but...has anyone somehow tied actual potentiometers into their arduinoboy to control mGB's parameters? I'd like to have kind of a self contained unit (I only use mine for playing with keyboard). Any ideas? I read one person who suggested hooking up the pots to another arduino, and having that arduino pass the midi cc data to the gameboy. Any help would be greatly appreciated!

Good deal. Thanks so much for the help everyone! I've got this, ordered a Chip Maestro, and am repairing a Commodore 64, so now I've got a ton of stuff to pump out some chiptunes!

Sorry, I misread, thought you meant which arduinoboy design did I follow. I used an arduino uno.

Thank you liquidcalm, you're a gentleman and a scholar. It works perfectly, apparently I'm just an idiot. It is funny you're the one that answered my question, I happened across your site the other day, I love the live looping video with the arduinoboy and kaoss pad and everything else. So good!

Jazzmarazz, I used 2player's design based off the original trash80 schematic

Two quick questions for you guys...my arduinoboy is working, but is there a way to get mgb to cycle through midi channels? Every note I play when connected to my junk 106 and my studiologic 990 pro, the only channel that works is the first channel. Both these keyboards can only output one midi channel at a time, but I figured that there would be a setting on mgb or arduinoboy to rotate the channels...is this not the case? I can change the channel and get the other voices to work singularly, so I know it is at least working...if there isn't a way to do this, does anyone know of a way to make Logic Pro to do this rotating midi channel thing so I can get some polyphony?

Secondly, am I able to take the ATMega out of the arduino and just use that singularly without modification with the arduinobiy circuit so I don't have to stuff my arduino in my project box?

Should also mention that the midi cable is fine, tested it with 2 keyboards

Any ideas? Gameboy is wired to it and providing power, i've tried reversing the wires for the midi, and still nothing...I'm pretty sure the rest is wired right, it boots up correctly and I'm using a pcb...

I didn't do that, voltage regulator was there in the correct place while the 9v was in place, and I didn't think that the 5v from the gameboy would kill it...but I do think it is strange that the gameboy won't power up with the power and ground connected

Hello,

Recently built an arduinoboy using MEOW's kit (http://meowindustry.blogspot.com/p/products.html,) which relies on either the GB link cable or a 9v with a voltage regulator to power it. Long story short, it seems as though it was working (except for 2 LEDs being dead and possibly a problem with MIDI,) but I didn't have a link cable to test it out. Got a link cable, soldered the wires to the leads (including the gb 5v power) and the gameboy wouldn't turn on. I'm positive I soldered the correct pin from the 5v and ground to the arduinoboy, I took a look at it multiple times to be sure. So, gameboy wouldn't start, and arduinoboy wouldn't start. I put the 9v back in to see what the damage was, and the arduinoboy will not start anymore. Also noticed the voltage regulator gets extremely hot very fast now. So I know that's dead, but I also know that isn't needed if powering the arduinoboy via link cable. I guess my question is, is there any way to test my ATMEGA with a multimeter (I don't actually have an arduino, this kit only used the ATMEGA,) because I'm afraid I may have killed it.

Interestingly, I checked out the LEDs with a multimeter and both were dead! Got a much bigger problem now, I'm gunna post a new topic sad

Yea, it is...was just hoping somebody knew off the top of their head, waiting to get the link cable to know if it is working or not may kill me.

It's being powered by a 9v, since I don't believe the link cable my roommate has has the power pin (although I'll probably do the mod at some point.) But yes, a 9v battery at the moment with a voltage regulator

Hello all,

I'm new here,  but hoping to get a bit of help. I built an arduinoboy tonight, and everything seemed to go fine. Unfortunately, I do not have a link cable to test with, so I'm unable to test with an actual gameboy (pretty stupid right?) I was able to get things working from an aesthetic level (when switched on, LEDs light up, although 2 do not. Not sure if that is a bad LED issue or not.) The problem is that when I connect my keyboard to the midi in jack....nothing happens. No lights. Is this due to the gameboy not being connected? I'm really hoping it is, because the midi is wired up correctly...

Thanks,

Christian
