XMF support

[fusoxide]

XMF (and by extension, MXMF) is another tree-structured format that includes both MIDI and embedded DLS files, mostly used on phones. Perhaps it would be worth adding support for in the future? Right now, only a few old mobile content players play the format as far as I know, such as Beatnik Player for Mobile Audio. It would be great to have support for this format on a modern MIDI player.

Do you have a link to specs or documentation?

Thx. I found that too and some other stuff. Unfortunately, only one 2.0 mxmf file. Do you have some other examples per chance?

There's some XMFs here, featuring samples: http://onj3.andrelouis.com/phonetones/unzipped/Panasonic/X701/
MXMFs also with samples: http://onj3.andrelouis.com/phonetones/unzipped/Nokia/6630/Ringtones/

Thx. I'll have a go at it.

v2.16 has been released with XMF/MXMF support.

Cool! I'm having some issues though:

• (M)XMF files that have an embedded DLS do not play.
  Decoding failure at 0:00.000 (Unable to load configuration for soundfont "C:\Users\fusox\AppData\Local\Temp\SF-58DA.tmp.dls"): "G:\phonetones\unzipped\Nokia\6630\Ringtones\Hummingbird.mxmf"
• The XMF files on the Panasonic X701 do not play either. While these also have embedded DLS, the error message is different:
• Unable to open item for playback (Failed to read MIDI file: Unknown unpacker 0x01 from MMA manufacturer 0x00010D): "G:\phonetones\unzipped\Panasonic\X701\Micro Revelation.xmf"

(M)XMFs that do not contain DLS play fine though.

• Hummingbird plays without a problem here. You have to use FluidSynth which supports DLS, BassMIDI does not. A converter to SF2 is on my To Do list.
• Some of the Panasonic ones don't play, indeed. The error message says it all: it uses a proprietary packer. The manufacturer is Beatnik Inc. I don't have documentation about the packer.
