Lexicon Lambda duplex support

I have a Lexicon Lambda USB audio interface. It works fine other than the fact that I can't get it to run in duplex mode. Right now when I record I use the Lambda for getting input from microphones and I use my onboard soundcard to output sound to my monitors. This is not desirable because I can't hear what I'm recording and what I'm recording along to at the same time.
I found this: http://www.spinics.net/linux/fedora/als … 01899.html which seems to identify the problem pretty well (assuming that he knows what he is talking about). No solution is offered and I am having serious trouble trying to find one myself. My only thought right now is to patch the module responsible for throwing the error so that it handles the way the interfaces are numbered when this particular device is connected to. The only problem is that I have no idea where to start. Do I have to recompile the whole kernel? The snd_usb_audio module? The usb module?
What I am asking for is some pointers on where I might start looking for the source code files so that I can attempt to remedy this problem, although any help will be much appreciated.

I do have an ~/.asoundrc and I have been through that wiki page multiple times before, I couldn't find anything that worked. The error messages I'm getting (from dmesg) seem to be from a lower level than the one which ~/.asoundrc works at. That being said, there are downstream solutions to upstream problems.
According to a follow up post:
They may have used the same code from their Omega, which I believe might have 8 interfaces, and just changed the number of interfaces without actually renumbering them.
So, the Omega might not even be susceptible to this issue.
Also, in the linux source code, I found out that linux-3.3/drivers/usb/core/config.c prints the error messages that were in the aformentioned post (and that I see too). I have not yet read enough of the code/docs to have the vaugest idea of how a solution might be implemented.

Lexicon Lambda Audio Interface - newbie question

OK, not strictly a Logic Express question, but I am using a Lexicon lambda audio interface with LE.
I'm new to audio interfaces, having just bought my second synth, so I needed an interface in order to connect both synths to the Mac.
Both synths are stereo (2 quarter-inch outputs), and having played around with the Lexicon I'm forming the opinion that I actually need a 4-input interface, rather than a 2-input, in order to connect both synths in stereo. I was hoping I could use an adapter on the two quarter-inch plugs to convert to a single quarter-inch stereo but I still only get sound through one channel.
Can someone confirm that it is actually a 4-input interface I need?
Thanks in advance.

Hi.
I 've had a lexicon omega for a while and have tried it in a macbook (osx 10.5) and a mac mini (osx 10.6.2).
The interface works wonderfully for about 10mins and then it stops processing the playback signal. I can only hear sound on the direct.
I've returned the interface to the vendor and they say it's fine. I've contacted lexicon support and they responded: "If the clipping is only heard when the Monitor Mix knob is set to Playback, this may be a problem with your Mac's Core Audio. In this case you may want to contact Apple or try reinstalling the OS".
Since I've tried with 2 different Mac machines, and with different osx versions, i think I can rule out trying to "reinstall the OS".
Do you guys have any idea how I can mend this?
It has become really frustrating...
Thanks

Problems with Lexicon Lambda Interface and Mac OS10.5

Hi everybody
I used my Audio interface Lexicon Lambda for a wile with 10.4 and it worked great. I updated now to 10.5.2 and since then I have buffer problems. I can change all the setting but it just change the time until it happen. Everything sound digital noise, a delay and so on.
For test reasons I went back to 10.4 and it worked fine, now I am back on 10.5 and still problems.
The answer from the Lexicon Pro Support was: "There are no firmware updates for the Lambda; however, there may be software updates for the Leopard OS that improve the performance of your audio application when using the Lambda hardware."
So any ideas, any persons with similar problems? Is it just me, but in my opinion this should be a Lexicon problem, am I wrong?
Thank you for all your answers.
Marco

Leopard is really a different OS. Lots of things have been changed in networking, security, core audio etc.
Changes often carry problems.
A 10.5.3 update is on the go but until then it's better if you remain with Tiger.
cheers

Why won't 'Speakable Items' Work with USB Audio Input Device (Lexicon Lambda)?

I am new to Apple Macs, yay for me!
I really want to use the 'Speakable Items' feature but unfortunately it just won't work with my Lexicon Lambda external USB Audio device.
Now, the Lambda is plugged in and working, and I know this from using the "Diction' feature which works perfectly.
When I go to System Preferences and click on accessibility>'Speakable items' and I turn on speakable items, I notice that under 'microphone' I'm unable to calibrate the microphone for some reason (if that's at all relevant).
I follow the instructions and have been asking 'what time is it?' and nothing happens
Any ideas?

I'm having the same problem, using 10.8.4. I have been using Speakable Items for a long time, but it's not reacting at all anymore. I'm on a Mac Mini and have tried several inputs, that all work with dictation, and are selectable inputs for Speakable Items. Zoom H4N, Apogee Duet and an UAD Apollo. The only problem I can see, aside from something in the OS, would be that I have SoundFlower and WavTap installed. Will try uninstalling them, to see if that helps.

Hi. I am trying to record a video on my iPad 2 but hoping to use an external condenser microphone via my Lexicon Lambda interface. Is this possible, and if so, how?

Trying to record a video on the default iPad 2 video app, but not using the iPad 2 internal microphone. I would like to use an external condenser microphone via my Lexicon Lambda interface. Is this possible?

Try a restart.
If that doesn't fix the problem, shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

Lexicon Lambda, Finale 2011, Hiperscribe, MIDI problems

I have a brand new imac. While it recognises my Lexicon Lambda sound card it cannot run hyperscribe function on Finale 2011. I had no problems with a mac book pro or PC wit same midi set-up. Any help?

How is your keyboard connected to the Mac?
Have you checked/changed your cables/connections?

Lexicon Lambda

I'm trying to record my guitar into GarageBand using my Lexicon Lambda USB Interface. I can record the midi input just fine with my keyboard, but I seem to be having trouble figuring out how to record my guitar through the interface. Any suggestions? I really would like to start recording as soon as possible.

Make sure to add a real instrument track
then on the right side of the screen (near the bottom) there is a setting for the input source.
select either Channel1(mono) or Channel2(mono)
if you are using the instrument input on the Lambda it would be Channel1 (mono)
is the guitar signal showing on the Lambda?

New feature to add: Manual Duplex Support for Non-Duplex-Printers

Hi,
I wanted to propose the implementation of a feature which helps users with printers that don't support automatic duplex printing.
+The feature should help to sort the document right (even vs. odds), start a first job, wait for an user's confirmation that he has put the paper back into the printer after first pass and start a second job.+
Printing on both sides of a sheet is very, very uncomfortable at the moment.
Is it possible to implement such a feature?
What do you think? If you agree, help to get some attention to this post!
Message was edited by: Deflex

Is it really so bad? It's only two or three mouse clicks more than what you are asking for. I'd hardly call that "very uncomfortable".
If you want to send a feature request to Apple, you can do it here: http://www.apple.com/feedback/macosx.html

Hp p1005 driver doesn't support duplex

The driver for my HP LaserJet P1005 (version 1.4.0) doesn't support the manual duplex option that was available under previous version of the OS. This behavior exhibits in all applications. Have tried deleting, adding, resetting print system. Other printers seem fine. Installed via USB.

OXR wrote:
I found a ppd file for a different printer thatThad duplex support, added 7lines of DuplexUI to the ppd file, which yields a dialog box, but alas still prints single sided. So, I think I'm close, but not there yet.
I doubt that another PPD file will work. Your printer does not have a mechanical duplex unit. Any duplex output must be done in software that is usable for all printers or is specifically part of the manufacturer's software for your printer model.
Remember also that your printer is a very dumb printer. It has to have its firmware sent to it each and every time it is turned on. You will not be able to just use any driver that contains a provision for duplex.
But you are spot on, for the current driver. Generic print only. I've p,ayed around with some of the other HP drivers, but get worse (no print at all) results. So I'm hoping the CUPS solution will work. Just missing a few things yet.
Your best bet is if an older version of the HP software is usable in Mavericks. Failing an older version working, you would seem to be left with only the chance that the PDF workflow that HP provides will work for you.

Support multiple clients.

hi, all
I have some ideas on it and want to see if it makes sense. May you share your experience/expertize? thx in advance.
The target is to support multiple clients in one server. It uses TCP socket. The design choices are:
1. Uses one ServerSocket for one client. starts a new thread for each ServerSocket.
2. Uses one ServerSocket for all clients. everytime accept() returns, starts a new thread for this client.
I think #2 is better since it uses one port number and less resources.
Any ideas?
thx
Tim

You're welcome. I posted an example on a Multithreaded Server that does this, it actually uses two threads per client to provide full duplex support.

Any way to override default printer settings into a PDF

Hi -- I work for a large organization that has lots of computers and printers and prints a lot of forms and documents. We are moving towards more digitization of documents and records including printing forms as needed as opposed to having large sets of forms onhand. This should save us a lot of time and money once complete as these forms often change and the old process would be to then trash much of these documents and re-print for just one change. The majority of our printers do have letter & legal trays as well as duplex support, however due to the vast number of users the default printer settings tied to each user and/or computer may be slightly different. While standardizing all the printer settings across all users/computers would be one solution, we don't anticipate doing this as depending on the job peformed the different settings may be more preferable / advantageous for that user.
As such the other solution I can think of is to hardcode the specific printer settings needed to correctly print a large document into that PDF file which may differ from that computer's print settings. For example, the default computer print settings may be to print on just 1 side but duplex would be encoded / scripted directly into the PDF so IRREGARDLESS of the computer/printer settings this document would always print duplexed.
Is there anyway to do this? I would need to do more than just duplexing -- ie some form sets would need to be both duplexed and 'fit to printable area' whereas some would need to be only on one page and 'shrunk to printable area', etc, etc. Our current practice is to insert a 1 page coversheet at the front of each document with the printer settings that need to be used for that form set, however this has been difficult for some users to do and has caused unnecessary time with our IT troubleshooting form printing.
-Brandon

Hi Brandon,
You can use the Print Presets in Acrobat for that purpose. Please follow the steps below:
1. Open the PDF in Acrobat
2. Open Document Properties dialog (using Ctrl + D)
3. Select the "Advanced" tab
4. In the "Print dialog Presets" section, you can choose DuplexMode as well as Page Scaling for this document.
Please let us know if this works for you
Thanks,

Two sided printing on HP with Yosemite no longer available?

Since updating my iMac to the latest Yosemite, (10.10.2) my HP all in one C6280 printer does not even offer the option of two sided printing. Is there a way to get this feature back? The printer used to do two sided printing, and the option used to come up, but no longer seems to be there. I read several posts which suggested renaming a preset, but in the preset dialog box, it indicates that this is no longer an option. Any help would be appreciated. Thanks

If it's greyed out, it could mean that your device does not support duplex printing under OS X. One thing you could try if you haven't already is remove the printer entirely then add it back in again. The drivers that Apple supplies are the latest drivers for this device, there are no full-featured drivers available for this OS version.
Also, verify that you are using the proper steps for manual duplex printing:
http://support.hp.com/us-en/product/HP-Officejet-6500A-e-All-in-One-Printer-seri es---E7/4083974/model/4083869/document/c…
If that doesn't work, you could try this two-sided printing application from HP:
http://ftp.hp.com/pub/softlib/software12/COL35975/mp-88750-2/HP_Two-sided_Printi ng.dmg
If the above doesn't work, I think an email to HP support is in order. I suspect that they dropped support for duplex printing for your device with the later OS versions. When was the last time you had duplex support? Was it automatic or manual (i.e. you had to flip pages and print again)?

CS4 Crashes when opening a PP project saved on another identical workstation

Hello,
I have 2 identical computers Running PP CS4 in seperate buildings. When I copy a project to a USB flash drive or network drive from workstation A and copy it on to workstation B, the project acts like it successfully loads and at the very last second when you can see the timeline and everything it crashes out.
My system: PC - Intel Core 2 DUO 3ghz processor (E7500) with 2 gigs RAM - Lexicon Lambda usb audio interface - NVIDIA GeForce 9800 GTX + video card on windows xp pro service pack 2. Premiere pro cs4 version 4.2.1. I went throught the steps in the "Guide to an effective question" and per the instructions there I have attached links to the DXDiag results, MSINFO32 results, and screenshots of a couple of the screens in Process Explorer: (these screenshots are from workstation B, where I'm trying to open the project file and it crashes)

>2 identical computers
Hmm... if they are EXACTLY identical, there is something you might try as a LAST CHANCE (not to be done lightly, since hardware signatures will likely mean that you have to RE-authorize Windows and all software)
Buy http://www.terabyteunlimited.com/image-for-linux.htm (or your disk imaging software of choice)
Make a drive image of GOOD computer to USB hard drive... ditto for BAD computer
After both images are made, write the GOOD image onto the BAD computer's drive and test
If all works well (after any RE-authorizing due to any hardware signatures) you are good to go
If things do NOT work well, simply write the BAD image back to the BAD computer and you are back to where you started
Do not attempt this unless the two computers really are EXACTLY identical !!!!!

Mac mini external speaker problems

my mac mini using an audio interface (Lexicon: Lambda) and linking with external speaker (ADAM: A5x). they can play music and video smoothly before Mavericks update recently. After the updated, I can't play music and videos with iTunes and youtube smoothly, but it is ok when played with internal speakers. I had tried to clean up my desktop files, emply trash, and release ram by OnyX, but all these does help, and i don't know wheat to do now, pls help! Thanks!

thanks all, I fix my problems finally!
I just tried the following process and then the probelm solved
1. turn off mac mini
2. unplug the usb of my audio interface
3. then change another usb port at the back my mac mini in order to plug my audio interface again
4. turn on mac mini
and it is smooth and fluencent when i play songs and videos on my mac mini now.
exactly, I don't know why my problem can be solved this way... but anyway...
this works for me!

How can I get Log Express to recognize my external keyboard? - NEWBIE

I'm using a Lexicon Lambda phantom powered converter (I think that's what it's called) to run my Left and Right 1/4" cables to, from my Kurweil master out. Then the USB cable from the Lexicon out, to the Mac. How do I get Logic Express to recognize the Kurzweil so I can record the Kurzweil's on-board sounds rather than using it as a Midi controller?
Very new to Logic and all of this-any help is appreciated in layman's terms.

OK - got logic to recognize the Kurzweil keyboard on a new track, I can hear the on-board Kurzweil piano sounds, but Logic is not recording it. what gives?
