Hi,
I'm looking for an "off-the-shelf" Multi-port MIDI interface, (Serial or
USB)
with some decent linux drivers. Anyone have any suggestions, advice,
stories,
pointers ?? ... i've googled but nothing interesting turned up.
thanks!

Hi,
a friend of mine is building a system that plays sounds on different
speakers (up to 8-10 mono channels ) based on certain input events such
as light sensors and mechanical triggers.
The audio quality does not need to be high.
Latency can be as high as 100 msec.
My question is what is the cheapest way to get 8-10 analogue outs.
(consumer quality).
I heard of USB speakers, could this be a valid solution ?
Are they supported under linux ? If yes which kind of models ?
Can one use multiple stereo USB speakers on the same USB bus ?
e.g. CD quality stereo audio uses 1.4Mbit thus I was wondering how
much channels one can reliably stream over USB so that there no
dropouts occur ?
Recent PCs have two USB outs, is this the same shared bus or can
one max out the bandwidth on both ports simultaneously ?
How about adding more USB cards, is this supported under Linux ?
The other alternative would be to use a multi-io card with 8 or more
channels or multiple 4 channel cards ?
The Terratec EWS88 8-analogue channels out seems interesting but a bit
expensive for my purpose.
How about using 2 4-channel cards ?
Which card would you suggest ? Hoontech ? Are these (or similar cards)
still available ?
Sorry for all these questions and thanks for infos !
cheers,
Benno

Hello All
I'm sending some midi data to synthesizer for playback
and it appears that the fifo /dev/midi (cmpci mpu401 driver)
is not emptying as fast as it should(could), since the play back
is highly irregular. Here are some numbers.
1) The timeing slice remains constant at 30 msec +/- 3usec,
timed both at the beginning and end of the loop,
so the irregularities are not due to loop variations.
2) A maximum of 64 bytes burst, with around 5 bytes normal
and an average of 1 byte (say) (ie many slices do nothing)
can occur during a slice, the buffer for the driver is
128 bytes with around a maximum capability of around 116 bytes
transmitted per slice, so the midi channel can easily sustain
the transmission rate at the rate I am sending information.
4) System load while the program is running is around 0.1%
5) The midi performance remains the same even if I do something
like build the kernel, and untar some package say glibc at
the same time.
When I say irregular I mean, for instance on a run of 16th notes
the notes will radically speed up and slow down. The notes all
have the correct pitches and voice changes etc. are all happening
correctly. Just this strange tempo problem.
Any thoughts or suggestions would be welcome.

Yes and No ;) i had one "old" cable to disk2 and when i tried the latency
test
on the 2nd drive (DMA33) all worked fine. I have the latest BIOS installed.

On my asus A7V266-E board i had to set down dma mode from DMA100 to DMA33
get LL working fine. (<3ms)

Greetings:
As of November 19 2002 the Linux Music & Sound Applications pages have
been updated. This site contains more links to Linux audio, MIDI, and
DSP sites than you can shake a stick at (== a lot), making it the most
comprehensive listing of its kind on the Internet.
The site may be reached here:

(As aways, the Japanese site will not update until midnight tonight.)

Hello!
I keep getting strange problems with libsndfile 1.0.1 lib. I first
noticed it running sweep and then I went back to libsndfile source and
tried out ht etests and they die at reading wav files.
josef:/usr/src/libsndfile-1.0.1/tests$ ./write_read_test wav
pcm_test_char : char.wav ..........
Line 314: sf_open (SFM_RDWR) failed : File contains data in an
unimplemented format.
josef:/usr/src/libsndfile-1.0.1/tests$ ./misc_test wav
update_header_test : header.wav ........
Line 175: sf_open (SFM_RDWR) failed : File contains data in an
unimplemented format.
I don't remember having any problems with libsndfile apps before and I
don't remember changing anything on my box lately.
Any ideas what to do and what to check?
Thanks and take care,
Miha...
We might be a bit early to the party. Maybe the real guests will kick
our asses out the door. Hope not ....
