Hi! First time poster here
I really like the Arduino platform. Its very easy to learn and lets you do a lot of cool stuff. However there are some major problems which keeps me from loving it. I have a interest for guitar effect pedals and I aspire to make digital ones using the Arduino platform.
The main problems when it comes to sound-programming for Arduino is the very limited program memory (cant write long complex codes) and the poor bit-resolution of the ADC and the DAC. Improving the ADC and DAC can easily be fixed by adding a external Audio codec (DAC and ADC). Now I've seen a few DIY-Duino guides around the internet. My question is. Is it possible to write the Arduino program onto more complex AVR chips with larger program memory? Or alternatively could one hook up additional memory to the Arduino and are there any guides on how to do this?
