Qtractor 0.4.3 System Exclusive setup feature and my hardware.

One of the new features of Qtractor is a Sys Ex message that can be sent when a MIDI track with an assigned instrument is connected to its output in the connections window.

Cool, this way I can use my Korg X3 in combination mode or sequencer mode, and keep that choice remembered in the song's Qtractor session.

Here's how I've set it up:

First go to "view" > "buses" in Qtractor's main window.
Then choose MIDI master bus, your instrument and hit the Sys Ex button.

Now give your Sys Ex message a name, enter the Sys Ex in the textfield below and click on the "add" button.

Now hit "Export" to save as .syx file.

I exported a "set-combination-mode.syx" and a "set-sequencer-mode.syx", so when I start a new Qtractor session and use the Korg-x3, all I have to do is open the right syx file, hit "Add" & "Ok" and the next time I open this Session, the Korg will jump to the right mode at the making of the connection.

Installing the pre-alpha version of Open-Octave

Open-Octave, the upcoming replacement for Rosegarden in my set-up,
is based on KDE3 so I have some troubles installing it ...

First I downloaded the most recent source-code:
peter@avlinux:~/src/openoctave/ git clone git://68.150.160.199:9418/var/git/openoctave.git

Then cd into the new openoctave folder, then build the configuration using cmake:
(don't forget the . after the cmake command)
peter@avlinux:~/src/openoctave/openoctave$ cmake .
[snip]
-- Didn't find KDE3 headers
-- Didn't find KDE3 core library
-- Didn't find the KDE3 dcopidl preprocessor
-- Didn't find the KDE3 dcopidl2cpp preprocessor
-- Didn't find the KDE3 kconfig_compiler preprocessor
CMake Error at /usr/share/cmake-2.6/Modules/FindKDE3.cmake:274 (MESSAGE):
Could NOT find everything required for compiling KDE 3 programs
Call Stack (most recent call first):
CMakeLists.txt:97 (FIND_PACKAGE)


-- Configuring incomplete, errors occurred!
peter@avlinux:~/src/openoctave/openoctave$


So I opened Synaptic package manager and looked for kde3.
I guess kdebase-bin-kde3 is the package I need
but it conflicts with the kdebase-runtime-bin-kde4 package, currently installed on my (kind of messed up) AV Linux partition, so this would require kmidimon, kchmviewer and rosegarden to be removed (amongst others less important to me).

Maybe I could reinstall kmidimon later, but at the moment I don't want to do that, since I've got a JSynthLib driver to finish and shouldn't let myself get too distracted because of this promising project.

For now, I'll just keep an eye on the Open-Octave-Project ... especially because they keep the focus on doing the MIDI stuff, not audio or even notation, while its code is based on the good old Rosegarden.

Creating a driver for JSynthLib and the Roland SPD-11

Back in 1998, I bought my first 600 neuro computer to get started with the official Cubase Vst 3.5, priced that day at 'only' 400 neuros. All my saved money was gone, I didn't have a decent job, but my future regarding recording music seemed secured, with an official dongle. it also didn't take long to get the blues 'cause my computer wasn't fast enough to run Vst plugins and the manual said I would also need a professional sound card.

It took until January 2004 before I first got a web connection and learned that Cubase Vst 3.5 wasn't supported anymore. The drivers I had been working on with dmaker were only useful for unsupported and expensive but 'old' software.

Now with Linux running, I use JSynthLib to edit and save the programs and banks on my Korg X3 synth, and I would like to do the same with my Roland SPD-11 but there's no driver been written yet.

I've read a book about Java and done most of the exercises but I'm still pretty new to programming, so it's a new challenge :-)
To make things a bit easier for myself and possibly others who may want to contribute/learn,
I quickly set up this wiki at spd-11.wikispaces.com.

And for now, I'll STFU and get on with my "unemployed status" job of writing the damn driver.
Cheers ;-)

fxload doesn't load the midisport 2x2 usb at boot

Since I installed the Ubuntu 8.10 generic kernel, (to get rid of a current multicore cpu bug in the -rt kernel version), the midisport 2x2 in my setup isn't loaded at boot anymore.

A quick way to fix it are these three commands:

Do this to remember the x and y values

:~$ lsusb | grep Midi
Bus 00x Device 00y: ID 0763:1001 Midiman MidiSport 2x2

Let the usb filesystems come to the kernel

:~$ sudo mount -t usbfs usbfs /proc/bus/usb/

Load the fish into the usb filesystem with the x and y values you just noted on your hand.

:~$ fxload -I /etc/firmware/ezusbmidi2x2.ihx -D /proc/bus/usb/00x/00y

If you see the little one come to life with a flashing led,
all is well and you can say 'it's OK'.
Man, I feel like I'm helping to write a new Bible, lol.

dmidecode on a Medion PC

dmidecode, a DMI decoder, can read information described in the BIOS about some hardware like the motherboard and processor.

It appears like Medion also is a motherboard manufacturer, I didn't know that.
The output of dmidecode -q on a Medion Akoya E5310D isn't quiet at all, so I used the option -s with some strings:

peter@ubustu:~$ sudo dmidecode -s baseboard-product-name

A list of MIDI applications on linux.softpedia.com

Hehe

I just made a public notebook at Google,
and pasted the result of a search for

Choosing hardware to build a linux musician dedicated computer

This is a draft

Requirements for Components:

Case: Must help make the computer silent and keep the components cool. A rack mountable version is a plus.
Power suply: Must be of good quality and match to the components' requirements.
Motherboard:
onboard sound: Make sure you can switch it of in the BIOS.
onboard graphics:
onboard ethernet:
CPU: Look at what you can afford and check the net for compatibility.
RAM memory:
Hard disks: One for the system and a fast one for the audio recordings.
Sound cards: Look at what you need and can afford, check the net for compatibility.
Graphics cards: Look at what you really need and check the net for compatibility.

the usual alsa troubleshooting commands

Some commands I use to get alsa going like I want it to.

Get the names of the sound cards:

peter@ubustu:~$ asoundconf list
Names of available sound cards:
HDMI
HDMI_1

Now I won't forget these anymore, if you've know other commands that I forgot about, please be welcome to leave them in the comments.

Edit: here's a nice diagram to show the structure of how ALSA works:

MEDION AKOYA E5310 D (MD 8394) Multimedia entertainment-PC

At the local Aldi supermarket, I bought this computer that seemed interesting for what I want to do: making music with synths, recording and using a lot of effects, rendering Blender 3D projects, editing movies etc.

Actually it was stupid to just buy it, because it comes with Windows Vista installed and has an onboard Intel HDA sound card that's not supported under Linux (edit: this guy got it working with the latest Alsa drivers). And the Vista drivers for midisport 2x2 didn't work either, but this didn't matter 'cause I wasn't going to jump back in the windows jail just because of one weak consumption moment in a silly supermarket.

Specifications of the MEDION AKOYA E5310 D:

Motherboard: MEDIONPC MS-7501 (here's the output of dmidecode) with AMD 780 chipset, ATI HD3200 onboard graphics (but no onboard port) ATI HD34xx audio, Realtek RTL8111/8168B PCI Express Gigabit Ethernet, Standard Microsystems Corp. 9-in-2 Card Reader
CPU: AMD Phenom X3 8450 Triple-core
Graphics card: ATI Radeon HD3450 256MB memory
RAM: 3072 MB DDR2 SDRAM (667 mHz ?)
Disk: 640GB WD SATA (shop)

Motherboard:
I'm not sure about the brand and model of the motherboard but it's one with this chipset:
http://www.amd.com/us-en/0,,3715_15532_15533,00.html#780G
AMD M780G chipset with ATI Radeon™ HD 3200 Graphics

Socket AM2+ , Chipset AMD 780G , Form factor: ATX , DVI: yes (no onboard slot) , HDMI: yes
onboard sound : hda hdmi , RV620 RS780 controllers

It's probably some version modified by Medion, when I boot the pc, I can already read MEDIONPC somewhere in the first three lines.

Hard Disk Drive:
Western Digital Caviar GP 640Go : SATA2 3.5in 7200rpm 16Mo (WD6400AACS)

UbuntuStudio_8.04 installed fine, 64 Studio 2.1 also installed fine, but when I start it, I get a black screen.
Also the 64studio 2.1 installer didn't work when I didn't set the BIOS to use IDE instead of SATA with the disk drives.
I think I'll have to enable the etch-backports repositories first so 64Studio can use the flgrx-glx driver for my ATI Radeon HD3450 graphics card. (edit: I wrote this at my first attempt to install 64studio, and I'm asking myself now if X was really the only problem.)

Another hint from Brian Blater I read in this thread on the ubuntustudio users list is this:

If you type exit at the initramfs prompt does the machine successfully
boot? If so, are these HDs SATA? If so you may need to edit your
/boot/grub/menu.lst and add rootdelay=90 to the end of kernel line.
You can try a different number other than 90, maybe start with 30, but
from what I've experienced, 90 worked for me and I've seen others use
120.

My guess is the SATA controller is not initializing fast enough and so
the boot partition on the HD is not available soon enough. The
rootdelay will pause the boot process to allow the controller to
initialize.

May help and is worth a try to see if this fixes the problem.

I've also posted something about this pc on the 64studio users list.

Conclusion:
I shouldn't just buy a computer in a supermarket.
If I want to stay local, I could have gone to e.g. linuxbelgiumshop .
Also do some good reading before getting any new hardware, it's all here in this linuxguide .

I'll gather all I find about setting up a linux musician dedicated computer in this post.

Installing gspca-modules in 64 Studio

Installing gspca-modules in 64 Studio .

The gspca-modules contain drivers for webcams, but they need to be compiled for
64 Studio before you can use them, so here's a little how-to ...
This should work for all webcams listed here.

(Make sure) this package is installed:
gspca-modules-2.6.17-2-

multimedia-486
version 01.00.04-2+2.6.17-9 (apt.64studio.com)
and this one too:
gspca-source
version 01.00.04-2 (stable)

To unpack the sourcefiles I did:

peter@64studio:/usr/src$ sudo bunzip2 gspca-source.tar.bz2
cd into the new directory:
peter@64studio:/usr/src$ cd modules/gspca/

Now prepare module-assistant:

peter@64studio:/usr/src/modules/gspca$ sudo m-a prepare
[skip]
a lot of messages came and 'cause all went well, it ended with
...
Done!

Now auto install gspca :

peter@64studio:/usr/src/modules/gspca$ sudo m-a a-i gspca
[skip]
again a lot of messages and 'cause all went well, again
...
Done!

The driver is now installed and the webcam works :-)

Installing LMMS 0.3.2 on 64studio 2.1

WARNING: Don't do this if you don't want to mess up your installation !!
Adding other repositories (like Lenny and Sid) is not recommended if you don't know apt pinning.

To install the latest version of LMMS, I simply added
deb http://ftp.de.debian.org/debian/ lenny main
to the repositories in Synaptic.
Then I did a search for lmms , upgraded my lmms 0.2 installation , and reverted the repositories to the default list.

With 64Studio, the repositories I normally use for Synaptic are :

deb ftp://ftp.mirrorservice.org/sites/64studio.com/apt/ 64studio main
deb http://ftp.debian.org/debian/ etch main contrib non-free
deb http://security.debian.org/ etch/updates main
deb http://apt.64studio.com/backports/ etch-backports main
deb http://wine.budgetdedicated.com/apt/ etch main
deb-src http://wine.budgetdedicated.com/apt/ etch main

The online manual is getting better every time I check it out, and it's great to have some extra standard instruments and VST plugins working in LMMS now :)

killall esd trick, pstree weirdness

After playing for a while with 64Studio , and trying some packages to change the look and feel of the desktop environment , suddenly I got an error message while starting Jack Control .

I posted a request for help on the 64studio users mailing list . (read it here)

The process esd was already using the hw:0 soundcard, so I could start qjackctl after first doing killall esd. (with Alacarte Menu Editor, it's easy to change the command in properties for Jack Control to "killall esd & qjackctl")
A second option is to go to the GNOME menu, then Desktop , Preferences , Sound , and disable software sound mixing (ESD) .
The third option is to replace libesd0 with libesd-alsa0, this way esd can keep running while I start qjackctl.

Something I still have to try out one day is what Ralf proposed to do here , I just didn't take the time to figure it out yet.

installed 64studio again

this is an old post

Yesterday I installed an old version of 64Studio again, and upgraded it to the most recent (2) (no cd or dvd needed, it all works with a simple 64studio dummy package after which I "apt-get 64studio-upgrade" (as root).

Now I'm back with the usual configuration stuff to deal with:
the mobo's onboard sound card is recognised first so put on hw:0
but I want my Delta 1010 to be the default card.

my first useful command is:

peter@64studio:~$ cat /proc/asound/cards
0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with AD1981B at 0xfebff800, irq 209
1 [M1010 ]: ICE1712 - M Audio Delta 1010
M Audio Delta 1010 at 0xdc00, irq 185
2 [M2x2 ]: USB-Audio - MidiSport 2x2
M-Audio MidiSport 2x2 at usb-0000:00:1d.0-2, full speed

(in ubuntu this would be

peter@64studio:~$ asoundconf list

but if do that command in 64studio, i get

Names of available sound cards:

with no cards listed)

Then I edited the /etc/modprobe.d/alsa-base file and added

alias snd-card-0 snd-M1010
options snd-M1010 index=0
alias snd-card-1 snd-I82801DBICH4
options snd-I82801DBICH4 index=1
alias snd-card-2 snd-M2x2
options snd-M2x2 index=2

to the end of it.
Let's see if it works ... I'll restart, because I don't know the command to reload the alsa-base file

More SynthEdit knob making tips

From the above tutorial I've learned how to use Blender a bit better again :-)
In short here's what I did :

the original image is the texture of a plane with 'shadeless' material, disabled 'traceable' and 'shadow' shades and 'win' map input.

That plane is the child of the camera.

The scene is set to output at the same size as the original image.

The background image in blender is the original image.

A '0.5 alpha' - 'Z-transp' - 'only shadow' shadowplane is put according to the image's floor. It also serves as the floor in the blender 3D set up.

Because I've done something wrong, you can see the shadow of the backgroundplane on the street.

The balls I added to the image with the pink floyd ladies show how it's important to use the right lense for the camera.

If you want to add objects into a piece of movie, that also is explained in
this great tutorial.

How to turn Blender-rendered images into working SynthEdit knobs

(follow these tips if you don't want or can't use KnobCreator)

Following to the post made earlier , here's how to finish the images from Blender (or any other images) into SynthEdit knobs .

Open the last rendered image ( in my case 0064.png) with the Gimp 2, hit 'ctrl+l' to open the "Layers" dialog. Select the other pictures (0001.png to 0063.png) and drag drop them in the "Layers" dialog.

Select the part you want to render as a rotating knob and choose Image > Slice so only the knob remains . Now choose Image > Canvas size and multiply the height to the number of steps your knob rotates .

Choose the move tool and select layer 1 in the "Layers" dialog, then click in the main window where we will move the layers one under/above the other. (This should be done by a script but I'm not capable of Perl coding to write script-fu for this purpose. With the shortcuts and a bit of patience I get myself through this for every knob or couple of knobs that are horizontally aligned. )

Use '-' and '+' to zoom in/out so you get a view over the strip with the little square image on top.
'Page up' and 'Page down' are shortcuts for selecting the previous/next layer.
The navigation keyboard buttons are for moving the layer, when 'shift' is hold down, the moves go with larger steps.

Now spread the layers over the strip, it's a repetitive job in this sequence :
'page down' > 'shift+down arrow' > 'page down' > 'shift+down arrow' > etc. (repeat 64 times)

Tip: It's faster to spread them first from a very zoomed out view and do the detailed finishing on a larger view.

When the knobs are one under the other, step 1 on top, the image is ready and can be saved as .png or .bmp to be used in SynthEdit.

How to design a layout for SynthEdit with Blender

Step 1: make a simpel knob to start with (to learn make a basic form , check the Blender wiki) .

Step 2: choose the number of steps, press 'F10' in the buttons window and set "sta" to 1 and "end" to the number of steps you want .

Step 3: go to frame 1 and position rotate the knob to it's start position, hit 'i-key' and choose "rot" .

Step 4: go to the last frame you want and set the knob to it's last position, hit the 'i-key' and choose "rot" again . Now the knob will rotate when you go to the previous frames .

Step 5: view the IPO editor window and make the Z rot line straight. To do this select the line, hit 'tab', select the vertex, hit 'shift+s' to snap them horizontal.

Step 6: select another knob and view the IPO editor window .
choose the same IP as the one you already rotated .

If you want lights, make them double so you can switch positions of one light(not lit) and another(lit). It's a good idea to add a text with the number of the light and make it parent of the light . When the synth has more lights or on of buttons, they can also made child of the text by selecting the child first and the parent (text) last and pressing 'ctrl+p' . Every frame where the lights should be lit , they can be moved all together. press 'alt+p' to unchild the mistakes you made.

Now go to the scene view, make sure output is set to .bmp or .png and hit the "animation" button. Blender will now render all frames from the start untill the end frame. The DOS looking window tells you where the images are saved and how much time blender needed to render each one. So you can calculate how much time you'll have for A BREAK !!

**shortcuts**
i : insert action into frame
ctrl+p : make last selected parent of other selected objects
alt+p : clear last selected parent relationship to other selected objects
F10 : in button window go to 'scene' buttons
shift+s : snap
e : extrude selected
ctrl+r in editor window : slice in X or Y direction
r : rotate (use the mouse and left-click to release or type the degrees on the numpad and hit enter)

To finish the rendered pictures, I've written another tutorial named
"How to turn Blender-rendered images into working SynthEdit knobs".
