LITERAL:
what is the DSP music box?
myself and three artists/musicians/engineers decided to fulfill a lifelong dream of ours and build a platform for portable algorithmic and generative music. we would control the hardware and software for creating music. not only that, but we were able to correct some of the shortcomings of the original EZKit. here’s what the board contains:
-an 80MHz ADSP-2187N DSP processor
-a FLASH memory (currently the AMD29F040, though we are most likely going to use a different FLASH with smaller sectors)
-an AD1885 CODEC
-trendy LEDs (blue AND white!)
-audio in/out
-RS232 support for download and for noah’s wonderful MIDI interface
-an expansion header for adding additional peripherals
