I just bought an M-Audio Keystation 49e off of craigslist and I'm at a bit of a loss on where to start to use it as an input device for muse or rosegarden.
Everything seems setup, but I'm at a loss on how to use it in the applications. It doesn't have any sound synthesis abilities on the keyboard, it's just an input device. Without the keyboard I usually go this route:
jackd -R -d alsa &
timidity -Oj -iA &
rosegarden
And midi events output sounds and all that jazz. I'm wanting to input notes / record from the keyboard. But still output all sounds in the aforementioned manner. If I could get those to happen while I record that would help a bunch. Maybe it's just too late in the day for me to wrap my brain around it at the moment.
I am using ubuntu 9.10 (kernel 2.6.31-9-rt) and an M-Audio Delta 1010 PCI sound card, and trying to get MIDI inputs and outputs to work on this sound card.I have Jack installed and working. MIDI signals from virtual keyboard or a MIDI player can be routed to fluidsynth, and fluidsynth's audio can be played back through the outputs of the delta 1010.I can use a MIDI sequencer (e.g. rosegarden or qtractor) to record MIDI from virtual keyboard, with jack handling the routing.
But, no matter how I configure the connections in jack, I can't get any signals from the "MIDI In" port on the sound card.Does anybody have some thoughts on how to fix this? Where is the disconnect between the delta 1010 and qtractor? I am concerned also that the "MIDI In" LED on the front panel of the Delta 1010 never blinks. There must be some basic ALSA configuration that needs to be done to activate and use these MIDI ports, or something. I've been trying to figure it out for days.
I'm new to ubuntu but i do have a basic understanding of programming, but nothing too serious. The reason I am mentioning this is because I have a little project. Currently I use JACK to control the transport of all the aps i use to make music with ardour, hydrogen and rosegarden mainly. I also have an external midi drum machine that I sometimes hook up into the mix via midi in/out, my drum machine (yamaha ry to be exact can send and receive midi data. My question is can I use the transport controls on my external drum machine to control JACK's transport controls? If there is already am app that does something like that, excellent!
Long story short - on my laptop, touch pad is recognised as PS/2 mouse. Everything works (moving, clicking, dragging, vertical scroll). But I often accidental click the pad while typing.Synaptic driver recognises it as ALPS glide point it seems (synclient -m 1 gives me back only x,y difference for the gestures, but X,Y coordinates are always 0,0) - so then I get everything right including disabling mouse on keyboard input - but scrolling doesn't work So I came up with 2 possible ideas - which I don't know how to do/test:1. Perhaps there is a way to disable mouse input while typing without synaptics drivers?2. Create a dummy input device (mouse), and tie synaptics driver to it. Add another input device in xorg.conf to point to the real touch pad as PS/2. And make the synaptics disable "real mouse" by enabling GuestMouseOff option.
I am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).
When X.org boots up, Synaptics touchpad works well. But when I remove the module it falls back to /dev/input/mice and don't use normal driver even when touchpad is available again.
Xorg.0.log: ... (II) XINPUT: Adding extended input device "Synaptics Touchpad" (type: TOUCHPAD) (--) Synaptics Touchpad: touchpad found # { rmmod psmouse && echo mem > /sys/power/state && modprobe psmouse; } (WW) : No Device specified, looking for one... (II) : Setting Device option to "/dev/input/mice" ...
How to tell X.org to try it's InputDevice again (without restarting X server)? rmmod psmouse is needed to prevent crashing of Acer Extensa 5220 when resuming from suspend-to-ram. Found answer myself: Doing xinput set-int-prop "Synaptics Touchpad" "Device Enabled" 8 1 after reloading the kernel module reloads touchpad. Now suspend-to-ram works OK.
I am building a midi synthesizer that I'd like to be able to control from linux. I know its a rather broad question, but, how do I go about this? At this point the hardware consists of a simple UART bridge, and I've already written a simple C++ program using termios to send the raw midi data to the device. Obviously I don't want to write a player/sequencer from scratch, so where should I start if I wanted to get this thing to work with, say, a sequencer like rosegarden? Do I write the driver for rosegarden, or hook into alsa or what?
I have a Kore Controller from Native Instruments [URL] using it as a sound card on Fedora 12. Its input knobs are supported by Linux, too, but they are pretty useless for me.It came out that these input knobs send mouse movements from time to time, letting my mouse pointer jumping to the upper left corner of the screen.
So I want to disable the knobs, i.e. I want X to not interpret these "knob actions" as mouse movements. What is the best way to achive this? Can I disable it somewhere in HAL configuration or do I have to modify xorg.conf? And how do I do this?Simply plugging out the Kore Controller is not an option for me because I use it as sound card.
I need to set the default input device to be the microphone on my webcam for when I skype, but it seems to keep resetting itself, so I keep going in and changing it.
I am right clicking the volume icon and going into Sound Prefs -> Input, and selecting the camera.
How do I stop it from forgetting this and resetting it?
I am trying to record a video clip, using my webcam, but sound synchronisation is always poor. I have used Cheese, UCView and VLC. One possible cause is explained in the reply to this question, but I am not an expert. In desperation, I now want to try ffmpeg. The ffmpeg documentation gives the following example
Code: ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg My system has no /dev/dsp, but does have /dev/snd with these files Code: $ ls /dev/snd
My touchscreen "LG Display LGD-MultiTouch" will be recognized sometimes as /dev/input/event0 and sometimes as /dev/input/event3. How to hardcode /dev/input/event0 using udev and xorg.conf?

Code: ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg I want to use alsa, not oss, but need to know the alsa input device name (/dev/dsp is created by loading the oss modules). By running alsamixer, I have nutted out that /dev/snd/controlC0 refers to the HDA Intel sound card, ~controlC1 is my USB webcam and ~controlC29 is the microphone built in to my notebook, but these are control devices, not inputs.
[Code]...
However, that does not explain which device is the mic built in to the laptop: by my calculation, it should be pcmC0D1c, but there is no such device. In /proc/asound/card0/pcm0c/ I have directories for sub0 and sub1, which I am guessing relate to the mic jack and inbuilt mic respectively. Do two physical mics share one logical device somehow? I am starting to really confuse myself, if you haven't guessed that already.
I think my question boils down to "How do I record a video clip on Fedora 14 using ffmpeg?", but I am specifically interested in knowing how to specify each of the alsa sound input devices for my system.
my thinkpad Edge 11 has some problems with the touchpad and the trackpoint, so i want to permanently disable the touchpad, but not the TrackPoint. Both are PS2 devices.
I have installed Lynx and want to use two X servers at the same time. Each server has its own ServerLayout section in xorg.cong. The first ServerLayout Section has AutoAddDevices enabled, so that new input devices are added automatically. The second ServerLayout has AutoAddDevices disabled, and one InputDecice pointing to /dev/input/mouse3. That way, this mouse is the only input decive affecting the second X instance.
Unfortunately, this mouse is also controlling the first server (due to AutoAddDecives). Can anyone tell me how to disable this? I want every input device to be added to the first server, except this mouse. In earlier versions of ubuntu, I used a hal rule to make hal ignore this mouse. So it was not added to the first server. Now that hal is not used by lynx anymore, I don't know how to do this. I have already read some things about udev and the xorg.conf.d folder.
I use a USB webcam with a built in microphone. It works fine, but every time I plug it in I have to go to sound properties and select it as the input device. There are no other input devices present on my system. Since it's the only one there, is there any way to get it to automatically select when I plug it in? If not, I think that would be good functionality to add. Does anyone know who or what team to contact about that?
No audio input device can be found in sound preference>input but in sound preference>hardware>it shows the input webcam recorder device.
When I use
Code: alsamixer
onto terminal it shows this
and also i checked cable device and everything. And it was working till I last hour. I rebooted computer then there's some problem, I haven't change anything before or after rebooting.
I'm using FFADO on JACK in order to use my firewire device (M-Audio Profire 610) and I seem to have the opposite issue as others who have similar problems. Everything starts up fine, and I can record audio into Ardour using my inputs, but I can't get any output from any of my 8 line outs.
I've checked the connections using QjackCtl, and I tried to route audio from another program (Audacious) but I can't seem to pull audio out of the device (or the computer won't send my device audio?).
I can't use my line-in/microphone jack. In system-management-sound input tab there is no input device listed, and the input controls are grayed-out. sudo lshw -C sound produced:

I am using Debian testing i386. Just upgraded to 2.6.39-2-686-pae. After reboot, and ever since, I am getting warning: WARNING: Could not find hdaps input device (No such file or directory). You may be using an incompatible version of the hdaps module. Falling back to reading the position from sysfs (uses more power). Use '-y' to silence this warning.
I have a bluetooth usb dongle which I cannot get to work. I start kbluetooth. The icon in system tray is blue (not grey). Right click on it -> Device Manager -> New The wizard starts. It sees my Palm, but then says: "Sorry your Bluetooth Device does not support input Service". I don't know what to do. Opensuse 11.3 kde 4.5 kbluetooth 0.4.2-10.5
On karmic the audio input device would constantly reset to muted. On lucid, it keeps resetting it to the microphone jack at the back of the computer (While I have a webcam up and running that it knows is what I use. How can I get it to remember my audio input? One more functionality issue till bingo. How can I give a window "Widget" status: I want it not to minimize when I hit ctrl alt D (Like conky and other widgets).
I'm having here annoying "problem" with my webcamera. Everytime I want to use it as a microphone it needs to be switched manually in sound settings menu. It's not a big deal but I would really rather let it be switched automatically like plug and play or something like that.
I have a computer with a trackpad and a touchscreen. I want to run unclutter if I use the touchscreen, and kill it when I use the trackpad or a USB mouse.
The I'm pretty sure the touchscreen is /dev/input/mouse0, and the trackpad is /dev/input/mouse1
I have a general idea of how this should work, but no idea what tools and commands to use to implement it.
I use a Logitech USB headset with microphone at work for phone conferencing, and for some reason whenever I restart Ubuntu (and sometimes seemingly at random times), the settings for the audio input device revert to the defaults (the internal audio hardware).I can always reset it back to the USB headset by going to the sound configuration menu (Preferences -> Sound -> Input), but if any applications that use a microphone are already running, they will need to be restarted in order to make use of the newly configured input device.
I am trying to hook up an external MIDI keyboard to Ubuntu (Studio) with no success. I can play MIDI files but not get the s/w to reguster any events from the MIDI keyboard. I have a soundblaster LIve! with front panel and am usng the MIDI in on this, with a ROland PC-300 kybd. Headphones work fine on the panel so I know this has been connected OK. The software (Rosegarden) 'sees' the keyboard as in input device but nothing happens when I play.
I would like to know how I can play a midi file in Slackware command line. I write "aplaymidi -p (port number) file.mid" and I see that it is working, but I can't hear anything. As I have Windows XP in a computer and Windows 7 in another, I have to convert the midi files into wave files in order to listen to them in Slackware using play. There is another thing that I haven't ever been able to do in spite of the fact that I have had Slackware installed in my computers since 2002, and this thing is: I have never been able to connect Internet using Slackware or any other Linux distribuition. I like Linux very much but I am frustrated at not being able to do these two things: to play a midi file in Slackware and to connect Internet.
i am having dell inspiron 1540 laptop installed with ubuntu 10.04 (updated). i wanted to install LAMP(Linux,Apache,MySQL,PHP) for software development purpose.
but after restarting the system, following things occured:-Message box appears saying "Ubuntu is running in low-graphics mode" Your screen, graphics card and input device setting could not be detected... OK
Then i get prompt saying what would you like to do ?Run ubuntu in low-graphics mode for just one session. i get a message starting display in one minute.....nothing happens ... i switch to text mode by pressing escape. There is a brown color star before: Speech dispacher configured for user sessions.on battery state there is a infinte loop i.e. no response and system just hangs there...startx at text mode makes the screen blank...
Please tell which part of '/var/log/Xorg.0.log' sholud be scanned to find required information.
i am a new to ubuntu How to solve this problem i donot have internet connection and its important that i get it repaired as soon as possible....essential to get it running else i will be forced to goto Windows...
