Lets clarify all this:
SMF: .mid
A format used first in Europe on the TS21i phone (and maybe more) which
is almost identical to midi in every way except that not all midi commands
are allowed and it uses a different character set than midi.
{ SMF is also used to designate midi itself. There are three main types 0,1 and 2.
2 is rarely used. }
Compact midi (cmidi):
The standard for midi on mobiule devices.... Not used at all as far as I know!
MFi: .mld
One of Faith's two main formats which is a lot like midi.
Used on imode handsets worldwide.
Cmx: .pmd (sometimes called cmidi)
One of Faith's two main formats which is a lot like midi.
Used on handsets worldwide.
SMAF: .mmf
Yamaha's format which requires a long long explanation.
It is also the format that MA chips understand. As thus, MA1, MA2 and MA3
have some very big differences, with MA3 being the most like midi. Yamaha's
homepage explains most of it in English.
All of these formats can contain wave files on newer handsets.
There are a few other formats: smd, qcp .... etc.
Some handsets use one format internally and another externally, and
some used multiple formats externally and only one format internally.
So as to what handset uses what format.... that's a big question.
Some of DoCoMo's phones use Yamaha's chip and FAITH's format (in Japan).
Its a different story in Europe and I don't know all of it.
