Then your MIDI implementation list is different to the one I found in
the Internet, since a dump request by this list needs different values
than those you used.
You send 44 00 00 for Casio, that's correct compared to the list from
the Internet, then you sent 70 for MIDI channel 1, that's also ok
compared with this list, but after that you sent 19, weil the Internet
claims it should be 10 to request a dump.
Than you sent 60, regarding to the Internet list its correct to request
the patch from current sound area.
You add two times 00, but the list in the Internet says that the ok
string 70 31 is needed.

Thank you :).

To be honest: I don't know, I've only fixed the kernel side of it. ;)
There are 1.5 ways to read the TCO's LTC output from userspace:
1. Via ioctl. Needs currently unreleased alsa-lib containing my
commit 4b169b05b48f4ea0196879b62b8c3fa5b050e806 and newest driver,
Takashi's sound-2.6 is fine.
Then, use SNDRV_HDSPM_IOCTL_GET_LTC. To the best of my knowledge,
that's the proper way to read the LTC and it's what I've fixed.
2. If the TCO is present, we create a MIDI output port sending the
MTC. At least I think it's MTC. Since the data is directly
generated by the TCO, the driver has no influence on it. No idea
if it helps in your case if you set this port as the MTC input
port in Ardour.
So it looks like for proper LTC support, we either need some converter
(maybe there already is one?) or ardour needs to be augmented. I have
absolutely no idea what the preferred approach is, but I'm sure Robin or
Paul do.
Maybe it's easiest to add another input path to one of Robin's LTC libs
that just runs the appropriate ioctl and parses the output. Since the
LTC is already decoded by the TCO, it should be pretty straight-forward.
Oh, and last not least: I don't own a TCO, so I cannot really test
anything. Fortunately, the ioctl is purely software, so a mockup should
do the trick.

Hey All,
I've written up a blog post on allocating (audio) buffers in real-time.
The trigger was designing the record functionality for Luppp.

CAPS Audio Plugin Suite 0.9.12
http://quitte.de/dsp/caps.html
New in this release:
Eq4p, a four-way parametric equaliser
http://quitte.de/dsp/caps.html#Eq4p
(Unlike Fons', this one uses parallel processing but lacks control
smoothening other than that provided by a continuous IIR filter
history.)
Elsewhere, a few stupid bugs have been fixed (one of them keeping
PhaserII from reaching strong effect levels), the documentation has
undergone a major revision, many plugins have been polished, some
renamed, and lots of unnecessary ones have been removed.

Enjoy!
Anybody from Europe, who still has got EPROMS used by some old
equipment?
It seems to be, that the EPROMS I burned in the stone age, without
protecting them against UV light, are still 100% ok nowadays.
I'm really surprised.
It's not completely off-topic for those who sometimes care about
dino-synth under European sunlight, when the RAMs where replaced by
EPROMS.
I'm positively surprised :).
Really, I'm stunned in a positive way :).

I think the small applications with narrow focus you find used on the
commandline are simply a good match for the Linux audio ecosystem with
its many one-man part-time projects.
On the other hand there's a strong desire among users and developers
for applications with a rich feature set and often also a pretty
graphical interface. It can of course be done, even by just one man,
but it takes a lot of time, vast depth and breadth of skill and
dedication and a stable list of features for both the project itself
and the libraries involved to make such applications *and polish them
to professional standards*.
I watch this ambition not without sympathy, but also not without
occasionally speculating what the Linux audio landscape might look
like with less lofty and more UNIX-shaped goals.

CAPS 0.9.10
===========
http://quitte.de/dsp/caps.html
The CAPS Audio Plugin Suite, a LADSPA library comprising classic sound
effects, various signal generators and guitar tone processing, sees
another update containing some bug fixes, minor sound improvements in
various places and a new plugin, "Spice", which, strangely, appears
not to be an exciter.
http://quitte.de/dsp/caps.html#Spice
In addition, the package documentation has been revised and some
errors corrected.

Enjoy!
Hi all
This weekend i got a message from the dev of Hypercyclic and Tonespace that
a new version of these apps is available and they includes jack support
You can find info about the arpeggiator and the softsynth here :
http://www.mucoder.net/en/
If you are interested in beta testing, you can contact the dev via this
page : http://www.kvraudio.com/forum/viewtopic.php?p=5449152
Notes:
- 64 bit only
- these apps are crossplatform, free, but not open source (however, the
dev is putting effort into linux support so that's gottta count for
something, right ?)
- i'm not involved in any way in this project, so it's best to contact the
dev directly if you have any questions (you can find his details here :
http://www.mucoder.net/en/about/)
grtz
