Hello,
I am a fairly new Linux user - I like what I see so far, but having
great diffculties with MIDI.
Specs:
Ubuntu Linux 5.04
KDE
Compaq Pressario 333 mhz (..I know.....)
256 RAM (again...I know...old machine)
SoundCard - Turtle Beach Santa Cruz 5.1
(manufacturer tells me it does indeed have an onboard hardware synth)
Roland Sound Canvas SC-88 hooked up via joystick port
Audio such as MP3 works fine through such things as Alsaplayer and Xine.
KDE's KInfoCenter / Sound tells me:

What app are you using to play the MIDI files? IOW where are the MIDI
messages that play the SoundCanvas supposed to come from?
Normally to play an external MIDI module from your computer you'd either
run a sequencer, or connect an external MIDI keyboard. But none of
these are showing up in your list.
Also are you sure the joystick port is enabled in the BIOS? Normally it
would show up as "MPU-401" or something.

Lee,
I am coming from a Windows environement where MIDI and such just
"works" . The screen capture was just doing the aconnect from the
command window with no other app running. Ultimately I'd
like to be running some algo software like KeyKit generating the MIDI
and directing it to the soundcanvas, or using some utlility like pmidi
to play an existing midi file through the soundcanvas.
Joystick port - at this point I am unsure of most anything. In this
machine's previous life as a Win ME machine it did work, though with a
different soundcard.
thanks,
Phil J.

OK, this is a common point of confusion, because Windows and MacOS come
with a toy softsynth, so you can just double click on a .mid file and
hear sound.
On linux, to do the same you would have to run a soft synth like
Fluidsynth. Launching the softsynth will cause an input MIDI port and
output Audio port to appear in qjackctl, and you'd just connect the
output of fluidsynth to the ALSA playback input of alsa_playback to hear
the sound.

OK. It's not clear that ALSA is seeing this port.

Hi Lee,
This tells me what it is seeing:

client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 64: 'CS46XX' [type=kernel]
0 'CS46XX '
Since I've been told that Alsa does not support the hardware synth on
the soundcard type CS46XX, getting the MIDI routed through the soundcard
to the Sound Canvas seems the only thing to do. I take it that the
joystick port should be showing as some type of "through"
port? So maybe anything Alsa,jack, etc. tries to route to CS46XX just
goes into the "bit bucket"?
thanks,
Phil

No, it should be showing as "CS46XX". Fortunately, it does. :-)

Anything sent to this port should go to the Sound Canvas.
Does "aplaymidi -p 64:0 something.mid" work?

On the command line you can use aconnect to do so, if you

Click the "connect" button, then click "MIDI". The rest should be
self

not suprising that you'd find it confusing. it is confusing.
1) sending MIDI to a h/w synth on a souncard
a) you need to find out which ALSA sequencer port is representing
the synth. the simplest way to find out is from the command line
with the command:
aconnect -o
the output should give you some clue about a pair of numbers
to use that correspond to your soundcanvas. For example:
---- output from aconnect -o on my system -------
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 62: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 72: ' MIDI 1' [type=kernel]
0 ' MIDI 1 '
32 ' MIDI 2 '
--------------------------------------------------
that third client, mysteriously enough, is an RME HDSP
with 2 h/w MIDI ports. the first h/w port would be
sequencer port 72:0, the second 72:32.
the pattern is: <client ID>:<port ID>
b) then get hold of pmidi, a nice command line tool
for sending MIDI to an ALSA sequencer port. use this
command to do what you want:
pmidi -p <clientID>:<portID> yourmidifile.mid
changing the values of <clientID>, <portID> and the name
of the file to something more appropriate, such as
pmidi -p 72:0 bach_tocatta_and_fugue.mid
2) getting audio back
This is actual much harder to describe. It depends on the
intimate and ugly details of your Soundscape's builtin
h/w mixer, and without access to it, it will be hard
to describe what you need to do. Every h/w mixer in every
card is different, despite the presence of a few
"standards" for such things.
What you will need is an ALSA program to manipulate the
h/w mixer. I like alsamixer, which runs in a terminal
window; I like it because it shows me everything and
doesn't try to be all cute like a generic windows mixer app.
The goal is to identify which signal stream corresponds
to the output of the MIDI h/w synth, and select it
as the capture source (in alsamixer, done by moving
the "focus" to that mixer/signal stream, and pressing
the spacebar.
After that, every app that records from the soundscape
will be listening to the output from the MIDI synth.
If this all appears arcane and absurd, don't worry, it is.
The problem on linux is that we (generally) attempt to use generic tools
that are independent of the particular h/w installed. For very simple
things, this works well, but audio + MIDI interfaces really do not tend
to benefit from the current approach that has been taken, and it
requires a lot of knowledge on the part of the user to make sense of the
information that is presented.

one idea was that MIDI and even audio connections can be made

application had a button to invoke [qjackctl, qjackconnect,

This is the MIDI port of your sound card. The cs46xx driver names it
"CS46XX" to differentiate it from any other MIDI ports you (might)
have.
You should be able to play to this port with
aplaymidi -p 64:0 something.mid
(or pmidi instead of aplaymidi). This port will also show up in your
sequencer application.
When I did the aconnect -i and aconnect -o I
didn't see any of the
through-ports - bad sign?
No; you don't need any Through port unless you want to route MIDI data
in complicated ways. If you really want it, you can load the
snd-seq-dummy module manually (newer versions of ALSA load it by
default).

Hi Clemmens,
From what I've learned so far, routing MIDI through the
"through"
port may be my only options. Apparently Alsa does not support the
hardware synth on the CS64XX (Turtle Beach Santa Cruz) sound
card. Routing to the external sound module appears to be
neccessary, and was my ultimate goal anyhow.
thanks,
Phil

I think #2 might be the easy part. The external soundcanvas has a
button which will generate a "test" signal - this seems to come back
through and out the speakers just fine. Seems to be "Line" on the
Alsamixer.
Perhaps ALSA is not seeing the port through which the MIDI signal needs
to go through to the external module? Your example of aconnect -o
showed a Midi Through port - mine does not show.
Minor fix or fundamental problem? Thinking the latter, as
[type=kernel] sounds like something fundamental to the OS I am guessing.....
thanks to all for the suggestions - at least it is narrowed down to some
"might work / should work" and "won't work" answers.

Ok thanks. I fired up qjackctl and haven't the
foggiest
idea what to do with it.
Audio applications which use MIDI via the ALSA sequencer or
even JACK do usually not autoconnect to [MIDI/AUDIO][In/Out].
You have to do it manually.
In Qjackctl klick on connect and connect your applications and
hardware ports as desired, regardless if it was MIDI or
audio.

fired up qjackctl and haven't the foggiest
idea what to do with it.
Audio applications which use MIDI via the ALSA sequencer or
even JACK do usually not autoconnect to [MIDI/AUDIO][In/Out].
You have to do it manually.
In Qjackctl klick on connect and connect your applications and
hardware ports as desired, regardless if it was MIDI or
audio.

64 should drive the SoundCanvas. This is usually the external MIDI port.

It does not mean that at all.

Phil - try configuring JACK to use 2048 frames/period, and try using the

I did as Paul suggested in qjackctl and set the frames/period to 2048.
Same error. At 512 frames per period and below qjackctl seems to run
fine. Above 512 I get the same errors that jack server cannot start.
Still no evidence of anything hitting the soundcanvas. Qjackclt
gave me the options of hw:0, default, and hw:1. The latter gave me the
heinous error message popup, former 2 did not.
BTW - alsaconf is not at all installed, nor appears available. My
synaptic package manager informs me that I do indeed have alsa-utils,
looking at the properties/dependancies the file alsaconf falls under the
category of :
Conflicts: alsaconf
Conflicts: alsaconf-0.4

I don't know if this will help or if it even has anything to do with

Hi Phil,
An idea - how do I know what to write in and how would
I do
it?
let me summarize:
* JACK runs well on top of your card. Did you try if audio
output via any JACK application works? I'd try playing an mp3
or ogg file with xmms via its JACK output plugin. But
currently you try to get MIDI working so this isn't urgent
* The Card appears in ALSA as a writable MIDI port, correct?
* If so you should test if MIDI goes out of the card. The
simplest way to do so is running something like vkeybd, an
onscreen MIDI keyboard. If you haven't it install, please try
installing it.
* It is important to know that Linux has very flexible MIDI
routing abilities thanks to the ALSA sequencer. OTOH, this
means that MIDI applications usually don't connect
automatically. Use qjackctl, Connections, MIDI to connect the
vkeybd to the MIDI out port of your card.
* Use the mouse or the computer keyboard to play some notes.
Does the Soundcanvas receive MIDI data?

Now that is an interesting question! I usually download/play mp3s
using alsaplayer, which seems the default. Xine usually plays my
CDs. When I open up XMMS with nothing else running except
browser and email client and go to Preferences / Audio - IO plugins,
I see Alsa,DiskWriter, eSound, and OSS as options. No mention of
Jack. I am quite newbie enough to not know if there is a sequence
of operations - i.e this has to be already running and that has to be
running....would think things should instantiate themselves as needed.
* The Card appears in ALSA as a writable MIDI port,
correct?
I think it is 64:0 CS46XX.
* If so you should test if MIDI goes out of the card.
The
simplest way to do so is running something like vkeybd, an

I looked, and my package manager doesn't have anything like
that. pmidi or rosegarden should be able to send MIDI to the
card....

If Rosegarden is running it would show up in the list from aconnect,
which it doesn't for some reason. Then you would just connect it to the

Hi Lee,
Perhaps I may have a fundamental lack of understanding of how all of this
works in concert? What widgets need I fire up in what order? Within a week
or so I may go in search of a sound card that Alsa and that system will use
And play midi via onboard synth hardware and has the required 15-pin
joystick port and put the Turtle Beach Santa Cruz card in this Win XP
machine. Any recommendations on cards meeting those requirements?
Many many thanks,

First launch Rosegarden. Then go into "Connect" in qjackctl, click the
"MIDI" tab, and connect Rosegarden's MIDI output to the CSxxx MIDI
input.

Hi Lee,
Well things went form bad to worse...a post earlier this week suggested I go
here:
http://demudi.agnula.org/wiki/InstallApt
so I did and followed these instructions:
If you want to use the latest A/DeMuDi stable release (currently 1.2.1) you
can download packages from the Internet inserting the following lines in
your /etc/apt/sources.list file:
# A/DeMuDi stable
deb http://demudi.agnula.org/packages/demudi stable main
So I did that. Later I ran synaptic it wanted to update - took about 2
hours or so. Went back and fetched vkeybd as suggested. All ok until I
rebooted the machine - now I have no internet connectivity at all! Ubuntu
pretty much took care of setting up the network connections when initially
installed, so I've no idea what to change or to what. How can I get back to
where I was before? Reintall Ubuntu? Wipe the Disk? ARRRG!
BTW - tried as you suggested - cranked up ROseGarden, then fired up qjackctl
- under MIDI connections RoseGarden shows up as a Writable Client / Input
port - is that right? Anyways, jack won't tun now no matter the
frames/period selected....
Deep sigh...

Because you never said that you tried connecting Rosegarden's outputs to
the MPU-401 port in qjackctl and playing back a midi file with
Rosegarden and it didn't work.
Lee
11:09 p.m.
Lee,
I never saw a MPU-401 port at all. A post a few days ago established the
fact that ALSA does not support the hardware synth on this card. Playing
MIDI appears to be dependant upon getting MIDI generated via software on the
Linux machine routed through the soundcard to the external sound canvas, the
audio output of the sound canvas being routed back through the soundcard and
to the speakers and also able to be captured by some software on the Linux
machine to be recorded. Is anything Jack-related needed to do this? I have
been told both yes and no, perhaps due to my lack of clarity in explaining
what is needed to be accomplished. I've tried running Rosegarden and then
Starting qjackctl and since my large blunder it cannot start the Jack server
at all (until I do the reinstall).
Thanks!

configurations, is to have your /home folder on a seperate partition.

Hi Lee,
Yes, it installed and ran perfectly the first time. However, the full
install of Ubuntu proved a bit much for that little 333 mhz machine, so
I had to do more or less a custom install - install the minimal Ubuntu
(server install option I think). Apt-get some pieces, get synaptic, and
then selected apps. As far as I can tell, a correct install the first
time....
Phil
Hey,
I only said a reinstall might be a good idea as Phil had installed
Ubuntu (which worked perfectly AFAICT, except the MIDI thing which I
think was a config error), then added a Demudi source to his
sources.list which I don't think is supposed to work, and which really
hosed things (lost the network).
So he asked me if a Ubuntu reinstall is the best way to go from here and
I said probably. Obviously don't reinstall if you have data you care
about!
Maybe this was poor advice. However when I was a new Linux user and
really hosed things I often found a reinstall was teh quickest and
easiest way to get back to square one.
I'd actually be quite impressed by any newb who could install a Debian
based system correctly the first time.

OH Yes!!
Been there on that, all working fine and then that little thought!!!
I'll just install that (?insert not really needed app on an audio WS!)
and Bye bye OS.
You really learn what not to install this way.
cheers

Eh, I've wiped out my systems a bunch of times, and it's always a lot
faster to get your settings back the second time.

New subject: [linux-audio-user] PD question - serial control?
hi - this is really a PD list question, but I thought it might be smart to
crosspost...sorry for any inconveinance...
I am currently, among other things (one step at a time), trying to figure
out how to control PD via the serial port. that is the question of the
hour. just want to use hyperterminal to send a word, like "hello", and have
pd do something based on that word, like print hello or something.
for background, the project (due tommorrow, handed to me last night) is:
a button box has 6 buttons: five record and one play. when a child who is
standing between a green screen and a camera (connected to s-video input of
a capture card) hits, say, record 1, a chip inside sends the text "record1"
to a serial output. on the other end, a computer running max/jitter or
pd/gem (probably the former) plays back a set video file (a different one if
it's "record2"), placing it in the fill of a chroma key, and records the
composite of the camera and the fill for 20 seconds, while the kid dances
around in front of the background. if the kid pushes the play button, the
last combined video is played back via the s-video output of the regular
video card.
i don't even have max yet cuz they haven't sent the serial number. so all I
want to do this minute is send the word "play" to PD via the serial port and
have it do something, anything, even just say hello. i'm very new to PD
though. I can get it to, for example, print hello in its terminal. but so
far documentation i read makes me think that the "serial" object only
outputs to the serial port as opposed to reading from it and parsing what
it's getting...

Hi Christoph,
You can get vkeybd from A/DeMuDi - you could possibly make life easier for
yourself by including these sources:

Much of this applies to making music on any Debian system.

let me summarize:
* JACK runs well on top of your card. Did you try if audio
output via any JACK application works? I'd try playing an mp3
or ogg file with xmms via its JACK output plugin. But
currently you try to get MIDI working so this isn't urgent
Now that is an interesting question! I usually download/play mp3s
using alsaplayer, which seems the default. Xine usually plays my
CDs. When I open up XMMS with nothing else running except
browser and email client and go to Preferences / Audio - IO plugins,
I see Alsa,DiskWriter, eSound, and OSS as options. No mention of
Jack. I am quite newbie enough to not know if there is a sequence
of operations - i.e this has to be already running and that has to be
running....would think things should instantiate themselves as needed.
* The Card appears in ALSA as a writable MIDI
port, correct?
I think it is 64:0 CS46XX.
* If so you should test if MIDI goes out of the
card. The
simplest way to do so is running something like vkeybd, an
onscreen MIDI keyboard. If you haven't it install, please try
installing it.
I looked, and my package manager doesn't have anything like
that. pmidi or rosegarden should be able to send MIDI to the
card....
* It is important to know that Linux has very
flexible MIDI
routing abilities thanks to the ALSA sequencer. OTOH, this
means that MIDI applications usually don't connect
automatically. Use qjackctl, Connections, MIDI to connect the
vkeybd to the MIDI out port of your card.
* Use the mouse or the computer keyboard to play some notes.
Does the Soundcanvas receive MIDI data?
Yes, it seems that it does. Maybe I have an unfortunate mix
of hardware / software?

I don't know if this will help or if it even has anything to do with
it but you can write in your hardware in qjackctl. I only had default,
hw:0, and hw:1 but I wrote in ice1712 and that's what I'm using now.
An idea - how do I know what to write in and how would I do it?

I did as Paul suggested in qjackctl and set the

Same error. At 512 frames per period and below qjackctl seems to run
fine. Above 512 I get the same errors that jack server cannot start.
Interesting. If this common device can't capture at 1024 frames maybe
JACK should default to 512. This still seems high enough to work OK in
non realtime mode.

Ok, so if this is not an ALSA problem at all,
then how do I go about
configuring
JACK in this manner? (I suppose there are some command line commands
to run?)
thanks,
Phil J.
p.s. I did find alsaconf in the KDE menu -
Debian/Apps/System/Admin/Alsaconf
but it wants me to log in as root (not as sudo su) and I don't recall
the password I set...arrg!
