That would be a good way of doing it if we just wanted a standalone MP3 Player
with a simpler UI. RS Components even do an evaluation board which implements
an MP3 Player, with LCD display and UI based on a menu and a toggle switch.
The cost is £11 plus VAT, plus the cost of the VS1011 chip; probably about £20
all told.
The problem is that we want the UI to be simple toggle switches on the front
of the ammo-box case for the system and the two players need to be
interactive, so that they don't try to fight each other and so that we can play
a wedding sequence which consists of bells chiming in the Tower, a Wedding
March and Widor's Toccata in the Chancel and then more bells in the Tower.
Doing it in a single device makes that much easier.
