Hi Tim,

If you can elaborate on what "2 minutes of pre-programmed sounds" means. I
really think this is key to what hardware you should select. Are they tones?
Is it speech or complex sounds? To pre-program a simple tone can almost be
infinitely smaller (memory/complexity wise) than other type sounds.
