I am trying to record from a receiver (not sure if that's the right
name, it's the amp/tuner, the thingy that all other components like CD
player, tape deck, video etc. connect to) and it seems like the levels
are too low (the soundcard is soundblaster live platinum, using alsa
drivers that come with kernel 2.6.5).
the receiver has two stereo audio outputs - one is marked as tape
deck recording and the other one as VCR output but both seem to be about
the same (and there doesn't seem to be a way to change them). I connect
them to the RCA connectors on the front panel (live drive) but even if I
set the mixer to 100% (on line in) the levels are too low. On vu-meter
the levels only go to about 25-30% (max) while the 'normal' audio is
somewhere between 50-75%.
I believe both the receiver and soundcard work OK (I can record from
receiver to tape deck, I can record to soundcard from other sources) so
I guess there's mismatch between the signal from receiver and what
soundcard expects. Is there anything I can do? do I need some pre-amp or
something? Seems crazy but does it make any sense to try to record from
speaker outputs? Is there any way to change what soundblaster expects on
input?
TIA

One of the JACK developers reported this problem on LKML and the reply
was very interesting, this could explain a lot of the weird latency
issues that laptop users are seeing.
http://lkml.org/lkml/2004/10/11/182
The basic issue seems to be if your laptop has a broken BIOS which
implements ACPI using SMM you are out of luck. Here is some more
information on the problem (near the end of the page):
http://www.infoworld.com/cgi-bin/displayNew.pl?/glass/bg112596.htm
If ACPI causes you massive xrun/latency problems then you might have
such a broken BIOS. If you are having weird latency problems with a
laptop, even with ACPI disabled, try to see if it corresponds to the fan
turning on or changing speed. If so then you might be screwed :-(
There does not seem to be a lot of hope if you do have one of these
broken machines. But we can at least identify the problematic laptops,
complain to the manufacturers, and warn people not to buy them.

Anyone got any clues as to why I don't seem to be able to get any MIDI
messages from the MIDI/gameport on my SB Live! Value?
I've got an evolution MK149 keyboard hooked up to it with the supplied
power/data cable (power seems to work, the lights come on), but when I hook
up a midi monitor to any of the MIDI ports on the Live! in alsa, there don't
seem to be any messages coming through at all.
No config files, since I'm not sure which ones to post... Can do so if you
need enlightenment.
Thanks for reading my woffle
I managed to get the 2.6.9-rc3-mm3 and thusly VP-T3 kernel built and running!
I had to patch some files:
To get mm3 alone working I had to patch a file that VP-T3 patches:
http://marc.theaimsgroup.com/?l=linux-kernel&m=109714329614794&w=2
and start the kernel with the i8042.noacpi option.
I am patching and building a new kernel that should not need the
i8042.noacpi option:
http://bugme.osdl.org/attachment.cgi?id=3838&action=view
M problem now is that I have ganed NOTHING with respect to latency. This
is what I run to do PD, and I still get xruns!
sudo jackd -R -d alsa -d hw:1 -r 48000 -p
sudo pd
my .pdrc:
-jack
-rt
-path /usr/local/lib/pd/externs
-path /usr/local/lib/pd/extra
-path /home/wade/pd/general
-path /home/wade/pd
-lib sphere~
-lib fftbin~
-lib zexy
-lib Gem
-mididev 1,2,3
-r 48000
-sounddev 3
-blocksize 1024
-channels 18
-audiobuf 8
What can I do to lower latency whilst eliminating xruns?
When I load a very large patch the whole machine essentially locks up,
sputtering and jerking with no response for minuets at a time.
Thanks for the continued help with my troublesome x86_64 machine.
All I want is a solid machine for performances...

It may not have the exact _type_ of controlls you are describing but it
offers a lot of complex control.

Hello,
I'm looking for information on the art of drum pattern
creation. I don't talk about "howtos" for various drum machines or
sequencers, I know how to use these, I just suck at creating good drum
patterns ;-(
I do differrent styles of music , folk , rock , jazz, classic,
experimental stuff, but no dance or techno stuff ( even though some of
my folk music out of my sblive synth feels a little more techno than it
should ... ).
One of the first thing I should probably do is study drum and get a
teacher or something, but I felt maybe some of you know some tricks:
what to avoid , what can be used at will, how to create fills... I even
though I could receive a pattern library full of examples.
I currently use rosegarden4 sequencer, the matrix editor is nice for
drum part edition, but I also have hydrogen and tk707.
And also, if you think another list would be more appropriate, tell me
which.
Thank you
Frank
apologies. I wanted to answer the last email privately in Spanish but I
didn't know that the default reply-to was addressed to the list.
I make a short translation of the wothful points I commented right there:
to repair the bug in the Demudi's keyboard of Languages different from
English:
xf86cgf -textmode and select "keyboard".
and also I said that they 've already released the 1.2.0 version of
Demudi, which works better than the betas and that there's good support
on the agnula user list at www.agnula.org.
that's it
It seems that the little "lunch box" form factor with a flat screen
monitor is really portable but has the advantage of giving you control
over the kinds of hardware you're using, as opposed to a laptop where
you're at the manufacturer's mercy.
I would think that your safest bet would be to convert a mac power book
into a PPC linux machine, but building a little linux lunchbox machine
would still be a lot cheaper than forking out $2000 for a powerbook, but
that's still better than spending $850 on a paper weight.
