Help with recording midi instruments : two sources at the same time

Hi -
I'm trying to learn Logic after using Performer for years, and though the audio is fine, I just can't get the midi to work doing something really simple.
I have a MOTU midi express XT, which is an 8 channel midi interface. Piano plugged into channel 1, drumkit plugged into channel 2. I want to play both and record both, which should be easy, but I am stuck at the first hurdle.
So, new project, add a midi track for the piano, and select XT1 and plays and records fine. Add a track for the drums, and try to put it onto XT2, and now the keyboard plays the drums when I press the keys. Likewise, the drum kit triggers the piano. I have tried unchecked auto demix by channel but that doesn't help.
This ought to be trivial, but even with the manual, I cannot figure out how to simply choose midi input and output per track.
If anyone has a tip I would be very grateful!
thanks
Steve

I believe that I have followed your instructions, but I am seeing the same result: both midi sources trigger (and record) each other. Hmm.
It looks like the midi channels are not set properly or something like that...
What kind of midi tracks have you created - Software Instrument tracks - if yes set their midi channels to 1 and 2 ? If you have created Standard Instrument objects and want to use them with external sound device check the midi channels of these Standard Instrument objects again in the Environment of in the Arrange track Inspector - they must be set to ch.1 and ch.2.
If you use a Multi Instrument set it to ch.All in the Environment and create tracks for its sub midi channels 1 & 2 in the Arrange.
The Autodemix by midi channel Logic setting must be enabled as Bee Jay mentioned as well both tracks must be armed "R" !
Go to Click & Ports Environment layer and have a look at the "Input View" Monitor to check the incoming midi channels of the external instruments. Play a piano note(let's say C2) on the first instrument which is set to ch.1 - you must see some midi message like:
"1 C2 56" in the Monitor - which means ch1. Note=C2 vel=56.
Trigger a drum note (A2 for example) on the second instrument (Drums Set) on ch.2, so it must be shown as "2 A2 78" which confirms that the midi channel i.s OK. If not, then you must check you hardware settings again etc.
PS. If these re-instructions do not solve your problem, please provide a download link of this Logic project song so we can check up it. Make a short description on which tracks you try to record or just name them "Piano" & "Drum Set" something like that.

[Bug] Writing to the same trace in Citadel from two Sources at the same time

Howdy
I am experiencing an issue and am looking to get some NI support:
I have two distributed applications that can write to a Citadel database at the same time.
And I am investigating the possibility of what would occur if both of them were writing to the same variable at the same time, with possibly the same timestamp data.
I did this in the attached VI by using the same timestamps with a constant for the data (either #1 or #2).
This generates an error, as expected, stating you cannot have two references open at the same time.
The data file, dumped from Citadel, contains 1000pts with all data from only one of the arrays (in this case #2) and everything looks fine:
However, what appears to be happening randomly tho, is that the same portion of code can also returns no error.
When the data is dumped from Citadel this file contains 2001pts - 1000pts from each array and one separator (or break) point:
You cannot write an older timestamp to Citadel without it throwing an error, but from further testing it seems you can write the same timestamp repeatably. So I am guessing what is happening above is race condition that is somehow allowing two references to be opened to Citadel which should throw an error but it does not and this is somehow allowing both sets of data to be written by both loops??
The data, IMO, is now corrupted.
Is being able to write to the same timestamp a desirable feature?
Or is this a known issue or a bug?
What about acquiring two references - bug?
Is there a workaround to protect the data from multiple distributed-application writes?
Cheers

The race condition of opening the refererence in two places at once should still apply to two different VIs running at the sametime.
Will a CAR be lodged for this?

If you open up the code and save it as a .vit, you don't get any missing VIs. Only when you change the extension without the aid of LabVIEW.
No VI should have missing members by simply renaming its extension outside of LabVIEW???
I think there is an issue with the VI.
Can you replicate the following and verify what I am seeing?
Attached is a Project with Main VI (contains a call to the Open Trace.vi polymorphic only), a Class and a Build Spec
If you Build the spec with the Main VI outside of the Class it works
If you place the VI in the Class, save then Build, the Spec fails with the error:

Close the VI

I want to play two sources at the same time - what software is there?

Hi
Something of an unusual request. I have CDs of natural background sounds (my favourite is one of the sea which I have on iTunes on repeat). The sad thing is, I have to choose between these and my music.
What I need is a free CD player (software) that allows me to play my CDs on repeat in the background, then I can use iTunes for all my regular music playlists, and have them both going at once.
Any ideas?

I've found something called SimpleAudioCDPlayer which plays the CD (and does have a Loop facility).
Problems:
1. there is no icon in the Dock, just a little icon that floats right in the middle of my screen (I can adjust it to tiny but it's not moveable and is a bit of a nuisance)
2. more seriously, there is no volume control which means I cannot reduce the sea sound to background sound.
So maybe someone knows of something better?

Two profile two thunderbird at the same time with same user account

Dear,
I would use two Thunderbird at the same time for two different profiles with the same user accounts.
I using linux OS.
I was thinking of using:
# thunderbird -P profile1 &
# thunderbird -P profile2 &
But when launching the second command nothing happens.
Only brings in the foreground thundirbird already started.
If possible use this configuration now or in the nex future?

As a rule thunderbird only runs one instance of a profile.
However, there are a couple of options you could try.
You could use an addon to esily switch profiles:
* https://addons.mozilla.org/en-US/thunderbird/addon/profileswitcher/
there is more help here:
* http://kb.mozillazine.org/Run_multiple_copies_of_Thunderbird_at_the_same_time
It does say: 'Multiple instances is intended for debugging, so use it at your own risk'.
One method would be to use: Start > Run
"C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -no-remote -P profilename
there is a space before '-no'
and also before '-P'
followed by a space and the profile name
You could create a shortcut/icon to run each separate profile.

How to control 8 current sources in the same time with labview?

Hi,
I'm a French student who have to create a program which is able to control 8 current sources in the same time.the aim is to plug the currents sources in the input of a laser.
If someone has an idea, it would be very nice to inform me !!!
Thanks in advance.

Is it really Tektronik or is it Tektronix. Tektronix is a major test equipment manufacturer. I can't find any reference to that model number on their site, though.
There are several resources for learning instrument control. One good place to start is http://zone.ni.com/devzone/cda/tut/p/id/4357.
Assuming that you have a NI GPIB controller for the pc, you will be using the Instrument I/O Assistant or the VISA commands to send/recieve data from the current sources. Without having access to the programming manual, I can't give specifics on what commands you need to send. Your topic mentions controlling them at the same time. Truly simultaneous control is possible in only a few situations. If you have a couple current sources in the same mainframe, you may be able to send a single command to set them all. It will really depend on the commands that the vendor has implemented. With separate mainframes, you will send commands first to one, and then another, etc. Again, depending on what the vendor has implemented, it may be possible to sequentially program all sources to a ready state and then trigger all simultaneously.

Generat two signals at the same time and reading voltage

Hii
i have try to generate two signals at the same time and read voltage from another port on the board(not have to be at the same time), i have not alot of expriens in labview
and i based my code of example(http://zone.ni.com/devzone/cda/epd/p/id/5197) from yours site and try to suit to my needs
now my problem is when i generat the 2 signals(that work perfect) i canot read voltage from another port on my CB-68LP
i can not find the problem and make it over i hope there is away to figer out and fix it.
i have two cards 6229, and two CB-68LP board.
labview 8.5.
my code is look like this - http://img142.imageshack.us/my.php?image=scrennshot2no2.png
(this works perfect).
and this is my code after suit to my need - http://img183.imageshack.us/my.php?image=scrennshotfl5.png,there is error exception at the right side.

sorry...
The AO tasks is very important they will be synchronize ,it is very importent the two tasks will start at the same time
and after it run at synchronize mode i will need to make reading of voltage
i gust try to make simulation of machin (i give that machin AO and reading from it voltage that all)
first of all i make the two signals(synchronize signals).
and after it i will need to reading voltage.
i can make two signals synchronize together.
i can make reading voltage
but i can't make two signals synchronize together with reading voltage
it throw to me this error message.
i am looking for away to figer this out.
thank's for any help

Two images at the same time

Hi!
I'm new into FCE and I would like to ask for some help. Can I work with two images at the same time? I mean, Can I superimpose two images to make one? How can I do it?
Maybe this is something easy, but I'm just starting,
thanks in advance for your answers
Message was edited by: angelcotallo

Yes, you can. You can put one clip on top of the other in the timeline. You can make both clips visible by reducing the opposite of the clip or top, or by scaling back the clips so they are smaller. You can reduce the opacity and scale of the clips in the viewer by opening the clips from the timeline into the viewer. You can also scale the images directly in the canvas when it is in Image+Wireframe mode.

Singletons running on two servers at the same time

Hello,
          we faced one interesting situation with our application, running on clustered BEA Weblogic 9.2. We implemented some Singletons (ie. Singleton Service in a Weblogic cluster) and they are running fine. Most of the time.
          Common scenarios: cluster is started -> the singletons run on one server; the server is brought down -> the singletons are started on the second server.
          However, we had recently two situations where the Singletons started on both servers! Here they are:
          1) We use Database Migration Basis and we have a dedicated table for Weblogic to capture current state of the singletons. Due to the fact that database (Oracle RAC) was partially available one of the Managed Server could not get the lease and probably assumed that no singleton is running, therefore started the singletons locally.
          2) Network outage: we had several minutes where none of our servers could communicate between them (neither between SASU MS nor with the database). Consequence: each MS decided to start the singleton locally (after some time, which I assume is the waiting time). Once the network came back the servers could communicate again but the duplicate singletons are not deactivate, so they are running in parallel.
          Anyone experienced the same or similar issues? How to prevent the above? Is the Consensus Migration Basis a better choice? (I think yes for #1 but not for situation #2).
          Any helpful answer is appreciated.
          Thank you, best regards,
          Remus.

In general its not a good idea. Running PSConfig will try to establish a lock on the configuration database. Doing that from two servers at the same time may cause the update to fail.

Run two VIs at the same time

Hello!
I want to know how i can run two VIs at the same time.
I mean that i want to run a second VI ( N.2) while another VI (N.1) is in
execution without suspend it (N.1)
If anyone has suggestions, please help me!
Thank you very much.
roby.

If you say "run a vi", I assume that you have the VI open in LabVIEW, then press the run button. (Some of the earlier answers taks about programmatically calling VIs, which I don't think is the focus of your question)
You can run as many VIs as you want at the same time. Simply press the run button of the second VI and they will both run.
Of course you should ensure that they don't use the same resources (e.g. DAQ device, or listen on the same TCP port, etc.) In these cases, the second VI might fail. (Also if the second VI is a subVI of the first VI, you won't be able to run it seperately, because it will be already running.)

Write a progarm to test two parts at the same time

Hi:
I need to write a program in LabView that is capable of testing two parts at the same time.
Explanation:
I star the test on a unit, once all the electrical test is done move that unit to the pressure test without loosing the current test information and continue the test of the unit thewn generate a serial number only if it passes all the test. Then while the previous unit is going thru the pressure test star testing another unit for the elecrical test and so on.
I am using LabView 2012
