(Matthew Mora: I read your post and liked it, and intend to respond,
but haven't got a round tuit yet .. gimme a little while ..)
Regarding MLan, maybe this is interesting information for any of you.
A bit of communication between a friend of mine and a Yamaha
representative.
It's interesting to me ...
First of all we would like to explain about our mLAN licensing
program.
What we call PTT license, which costs 200,000 initially and ? 100,000
annually as you know, provides you mLAN specificaiton. The
specification
describes mostly on mLAN specific connection management system.
The reason why we do not open this specification to the public is the
specification is not stable enough. We are beeing involved in a
standardization process for connection control protocol but it will
take
a year or so befor it is finised.
Hmmmm!
Well, I hope this is true. If they really do open it up, all will be
forgiven by me, FWIW. But what of the people who shelled out all that
cash to get in early? Ah, well, who cares ;-)
On the other hand, audio and music data transmission protocol, which
mLAN adopts, is completely puplicly availabel specification. So,
anybody
can freely write a driver for audio and music transmission protocol.
Since this requires only isochronous service on IEEE1394, this driver
will well function as a building block for mLAN.
We believe that writing this driver must be a good starting point.
We were asked almost same by Advanced Linux Sound Architecture project
and replied same as above. Do you know the group?
I know that group. I was semi-involved in it for a little while, mostly
on the MIDI side of things, and I wrote a couple of programs using it.
When I returned to the Mac and threw in my lot with OS X, I lost track
of it, but it's a really nice system. Only way to fly for audio on
Linux, IMHO. It began life years ago as a driver set for the Gravis
Ultrasound soundcard, but eventually grew into more drivers, and then
pro-audio-oriented guys got involved.
I do think CoreAudio's a cleaner design, but it has the benefit of long
experience behind it, which of course ALSA didn't have. But that's not
to say that ALSA is a crufty hack - far from it. There's some really
slick stuff in there. The MIDI and timing stuff in particular is very
nice.
ALSA's all open-source, and naturally they want mLAN drivers. I'm sure
someone's trying to work on one even as we speak.
P.S.
