I had to share my last project with you, all the members of AVRFreaks, because some of you helped me a lot answering some of the questions I had while creating the board. Thans for your help!
"Synth Core A" is a development board I designed to create my own audio synthesizers and music controllers. It is composed of a 32bit microcontroller with DSP features ( Atmel AVR UC3A ), a CPLD , and other standard elements usually found on synthesizers like MIDI, potentiometers, LCD, stereo DAC, USB ...
The initial idea when I started the project, was to design a board with most part of the hardware and drivers I would need to create my custom medium range audio synthesizers. Having the board and the most important drivers ready will allow me focusing on the pure audio and interface design tasks every time I develop a new system.
