Hey all
I believe there is a certain set of features a DSP board needs to have. Here are things I think are mandatory:
Codec (at least 2x2 channels)
-- How else to get audio in/out?
Midi
-- This ubiquitous standard cannot be ignored
Swimming in RAM
-- for time delay and table-driven effects
CV I/O
-- again, a modular standard
USB
-- for fast comms to a PC
Now there are implementation details not covered. For example I would have an AVR coprocessor handle Midi, USB, and possibly CVs. In other words, off load all non-dsp stuff onto a processor better suited for those kinds of tasks.
I think a board like that would be pretty universal. Now I know some are a bit intimidated by the thought of coding a DSP, and adding a coprocessor just ups the ante. Perhaps a clever implementation could have the AVR as an option and run without it if needed.
Man, this is exciting!
