Sonic AS is a GBA/DS Midi player.
Sonic AS has variable polyphony on the GBA. It has support for variable music players, and the DS version can handle PCM8/16 and ADPCM data, as it uses the hardware channels.
The GBA version can also have either nearest neighbour interpolation (that is, no interpolation; this is fast), or linear interpolation, with .23 fixed point accuracy, which can be toggled by changing the variables in sasInternal.inc.
Since it's written in all assembler, the memory footprint is rather low.
All processing is done on the ARM7 side, with the ARM9 simply signaling to play/stop, etc.
