OK I managed to compile it in 1.6.0:

1. Install the latest version of Gameduino 2 libraries (I used the "Manual" part of this guide: http://www.arduino.cc/en/Guide/Libraries )

2. Start up (or restart) the Arduino IDE

3. In patches.h, replace "PROGMEM PATCHINFO patchInfo[440] = {" with "const PATCHINFO PROGMEM patchInfo[440] = {"

The EG-101 sketch should now compile.

Hope this works for you :)

Oh gosh, it was an arduino ide version issue!  That's my fault for playing with a new Yun in 1.6.3 (the yun rocks so far btw).

Thank you James, i'll get it running and share some pics of the mods.  I also want to add some menus to control the bend matrix. i need to do some more research into gameduino to see how to modify/wrap to use with my crappy 3.2 tft.

As far as I know the GD2 library only works with the GD2 shield, which has it's own touchscreen.

I last compiled it back when Arduino SDK 1.0.5-r2 was the latest. Seems since then the SDK/API has changed a bit, if I try now with 1.6.0, it does not compile. (But does compile with 1.0.5).

I'm pretty sure it's a common issue and there will be a fix somewhere in the Arduino forums.

Many thanks for sharing this on github james!  yes your method is how i was thinking about implementing the serialwrites, the set RPN to NULL at the end is a good thing to know. I hope to post some images of my 303 build once she's zipped up. (just waiting on a dual potentiometer from mouser to replace a sadly damaged volume knob)

Looking forward to seeing your project working.

James, this looks like you are sending NRPN from the arduino, any chance i can get a link to the codebase?  i'm modifying my old 303 (IC3 pins 4,5,10,11,32,33,34,36,43,44) and i am looking to integrate a mega/touchscreen combo for controlling parameters and a 'bends' crosspoint matrix.  

Hi Samuel

I have uploaded my code for this project to github:

https://github.com/james7780/EG101/

Here is the relevant part of the source code for sending NRPN changes (please note that this code sort of works for me, but may not even be correct):

//  Sends a MIDI NRPN change
void midiNRPN(byte channel, byte msb, byte lsb, byte value)
{
  midiSerial.write(0xB0 | channel);
  midiSerial.write(0x63);
  midiSerial.write(msb);
  //midiSerial.write(0xB0 | channel);
  midiSerial.write(0x62);
  midiSerial.write(lsb);
  //midiSerial.write(0xB0 | channel);
  midiSerial.write(0x06);
  midiSerial.write(value);
  // Set RPN to null so that further spuriuous controller messages are ignored
  midiSerial.write(0x62);
  midiSerial.write(0x7F);
  midiSerial.write(0x63);
  midiSerial.write(0x7F);
  delay(50);
}

Cheers - James

 I am hoping to use the GD2 library with my 2560 and touch/tft.  I'm having trouble getting the patches.h  PATCHINFO struct to compile, i'm messing with how PROGMEM is used .  it wants PATCHINFO patchInfo[440] to be const, and then i'm having trouble with the char name[14] requiring initialization ... have you seen anything like this in your compiling?  You have put so much work into building out the menu structure, i want to try and get it working.
