Hi,
I was wondering if it is possible to connect the breakout box of the
delta 66 to the audiophile 24/96 pci?
I want to connect my headphone to my maudio audiophile...

I'm building an Arduino-based MIDI pedalboard. The FTDI USB serial device does not show up as an alsa-seq device, but rather as a serial port.
Some time ago, I remember downloading and using a small daemon someone wrote, which connected this serial port to an ALSA seq port. I have it somewhere on one of these computers, but I can't figure out where. Also, the Googling I've done has come up with lots of falst positives and not the actual goods.
Anyone messed around with Arduinos and ALSA? Or know where this daemon might be?
Thanks.

When a LADSPA plugin is being sent zeroes-- i.e. when the volume of the input data is down to nothing-- is it still sucking up CPU cycles?
I understand from the JACK API that anytime a client gets a callback with data, it has to drop down and deal with the data and then return, even if the data is zero. But that could be lightweight, if the data are zero, or is that very compute-intensive for the plugin?
I'm trying to build an outboard effects chain in various LADSPA hosts (JACK Rack, ecasound, AMS, others... haven't settled on one yet), and when I've got that plugin's volume MIDI'ed down to zero, I'd like it to not be dominating CPU cycles at that time.

I meant to reply to the list, so I am forwarding our conversation to
the list, in case anyone else needs the info.
1) input gain/balance connects to bypass.
2) bypass connects to eq OR delay
3) eq connects to crossover
4a) crossover low connects to compressor 1
4b) crossover mid connects to compressor 2
4c) crossover high connects to compressor 3
5) each of the 3 compressors connects to its own stereo width/balance unit
6) all of the width/balance units connect to the boost unit
7) boost unit connects to the limiter
8) limiter connects to the master volume
9) master volume connects to output
10) delay (up at bypass above) connects to output

A crossover is a unit that gives three outputs for every input (so
this is two in six out), there is a low pass output, a mid range
output, and a high pass output. The cutoff for the low pass is the
same as the lower band of the mid range, and the cutoff for the high
pass is the same as the upper band of the midrange, thus it cuts the
audio into three distinct signals.
Hi
A couple of weeks ago I announced a gig with my electronic project,
modlys. One of the audience recorded a couple of tracks on his mobile,
and the first one is here:

Fons,
I'm having much enjoyment experimenting with Jconv, and have a further
question.
I've set up a multiple input output .conf, using your /impulse/copy
function.
It works really well, and i've been adding them up to my current test which
is 18 ins, and 18 outs, being 16 ER's, and 2 Tails. (more or less.)
This is with the "greathall". wav.
(And the naming function works a treat, and makes things easy to see and
identify quickly in a patchbay.)
There's a lot more to do, including tweaking the ER start and finish points,
but, and this is the Q:
I can set the jconv outs, to ardours ins, and pan them, so the ER 'image' is
in the same location aurally (roughly, for now) as the dry signal.
But is it possible to 'pan' the ER within the .conf itself, per in and out,
including the impulse/copy ins and outs?
Or can i only do this within Ardour, or another app?
At the moment, everything's coming out in the middle, and i'm considering
adding busses to create a panned sound image. (At this stage of template
building, anyway)
Alex.

Hi
I went ahead and got myself a edirol fa-66. Having no experience with
firewire I have no idea why it doesn't work. The problem is that jack
(qjackctl) seems to start up fine, but dies after a few seconds. My jack
settings are IMO conservative: buffer size of 256.

Hello Everyone!
I'd like to know the basic signal path for the JAMin effects.I know there is
a diagram, but useless to sightless eyes. :-)
So could anyone please tell me, how the basic effect (EQ, compressor,
Limiter, stereowidth) are concatenated? If you wonder, which way is best: Fake
ecasound Chainsetup, serialised tree like this:
root(left_1(left_2,right_2),right_1(left_3))
That is only in case it gets complicated.
Kindest regards and thanks in advance
Julien

Studio XX :: Atelier Supercollider Workshop : Marije Baalman
<Http://www.studioxx.org>
French Below
SuperCollider workshop with Marije Baalman
Studio XX welcomes audio artist Marije Baalman between April 20th and
May 11th who will undertake a four (4) session SuperCollider Workshop.
SuperCollider (SC) is an environment and programming language for
real-time audio synthesis and algorithmic composition. (SC) provides an
interpreted object-oriented language which functions as a network client
to a state-of-the-art, real-time sound synthesis server.
SuperCollider was written by James McCartney over a period of many
years, and is now an Open Source project maintained and developed by
various people. It is used by musicians, scientists, and artists working
with sound.
The workshop will teach participants how to make synths in
SuperCollider, how to use them with pattern structures and how to use
input devices. Using a combination of teaching materials and practical
exercises, workshop participants will build components to used in a
final composition.
The workshop will be taught on a Linux system, but SC can also be run on
OSX (>10.4) and Windows. The version used in the workshop will be 3.3
(the latest stable release), available from Sourceforge. Participants
may bring their own laptops with SC installed, or use the computers in
The XX Lab.
Dates: Every Monday from 6PM to 9PM, April 20th util May 11th 2009
Cost *: 200$
The workshop will be taught in English.
For information: 514.845.0289 or by e-mail

I'm looking for a note editor for linux to input scores from fake
books. I'm just staring out with the piano and I want to use the
generated midi to help me in my right-hand and left-hand practice.
So here are my criteria:
1) Can use chord symbols as input and print chord symbols.
2) Can export to midi and also export staves separately.
3) Can change tempo of exported midi.
4) Textbased or gui doesn't matter.
Another really cool feature would be Midi -> Fake book style
conversion. ie I input a midi file and get back an easy to read piece
of sheet music, with chord names. (If I import an average midi file to
Rosegaren the resulting sheet music will be a tangle way to hard to
read for a beginner like myself.)
