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?

Apple TV plays two languages at the same time!

Hello,
I ripped some of my DVDs using handbrake. I added two language tracks (original language + my mother tongue).
After adding meta data with subler i also checked both language tracks at subler so they will both appear in itunes.
Everything works fine when i watch the movie on my computer, i can perfectly switch languages in the settings menu.
But wen i stream it to my apple tv (i use itunes on my computer at chose apple tv as streaming device/airplay instead of browsing with the apple tv directly)
it will play both languages at the same time! no matter if i chose a language in itunes or not, it always plays both languages.
Did anyone else have this problem?
Or even a solution?

When an apple tv and an airport express are connected at the same time and the apple tv is powered on, the itunes multiple speakers feature will show both the express and the apple tv. you can select either, or both using the multiple speakers option.

How to play two videos at the same time

Hi everyone!
Ok, so what I'm trying to do is basically play two videos, which are already saved on the computer, at the same time. I can get one video to play, but when i try to start another it just displays a blank screen.

Anyways, heres the modified code in case it will help anyone

[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

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:

Save the VI
Close the VI

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.

Play two instruments at the same time?

Hi!
I'm stuck with GarageBand right now, where I can only play one instrument at a time. Preferably I want to play both (for example) piano and strings using one real-time MIDI input. Is it possible to do that with either Logic Express or Pro?

Do you mean play the same thing at once with two instrumets simultaneously playing two different sounds?

Can itunes play two songs at the same time? Mine can!!

If you let a song run until just before the end and then click to an earlier part in the song on the time bar, itunes starts playing both that tune and the next one.
Does this happen with anyone else?
What a basic error, how did apple not catch this?
Peace and God Bless.
ibook g4 Mac OS X (10.4.8)

Actually, I have the same problem...only moreso.
When I'm streaming from another computer, my songs frequently start double-playing without my doing ANYTHING at all. Right now, The Skeleton Killers' "Despair" is doubling up--that's twice the dirge--and I wasn't even touching the computer when it started.
Oh, goodie! One of the streams has finished and the next song, George Michael's "Outside", has begun, now running concurrently with the last minute of "Despair". I can't tell you how poorly these songs go together.
The problem started with 7.0 and continues with 7.0.1
Apple! Help!

[KDE] Unable to play two sounds in the same time

I am switching from gnome to kde, and i did a fresh install (i formatted) the entire system.
The problem is that, for example, before in genome i was able to have songbird playing while a movie was being as well played and if someone talked to me via pidgin, the warning sound would be heard as well....
In kde, if i am listening to amarok, i cannot listen the audio from a video from youtube, and sometimes, while i am listening to music, someone talks to me on kopete, stops the playback on amarok and then plays the new message warning sound...... i understand this is a misconfiguration of my audio system, isn't it?
Where should i start from? I am using xine as sound engine (phonon-xine)-.....
Thanks!

Maybee your gnome was configured with pulseaudio?

Is it possible to play two videos at the same time in Captivate 4

My idea is to create some e-learning material which shows a screencast of a powerpoint presentation and a video in the top left corner of the screen showing somebody presenting the slides.
Does anybody know if it is possible to do this with Captivate 4?
I know this functionality is provided in Adobe Director.
Any help regarding this will be greatly appreciated
Kind Regards
Jay

Hi Jay
Do you have the eLearning Suite? If so, you have Adobe Presenter available to you. If you don't, you should be able to download the Presenter installation file and evaluate it.
Presenter is an add in for PowerPoint. The neat thing about it is that it provides for a Table of Contents type of functionality as you see is configured in Captivate. But the twist with that is you are able to do something you cannot do in Captivate. You are able to insert videos inside the TOC area!
Just musing out loud... Rick

How can you listen to music and play a game at the same time?

How can you listen to music and play a game at the same time?
I am playing music, by starting the Crash Baandicoot Nitro Kart 3D game it shuts off the music playing. Is there a way around this?
It seems like this should be possible.

Select the music play list you want to listen to and start it playing. Go back to the home screen and start the app you want to use, music will stop. Press the home button two time quickly and it will bring up a simple control for controling the music. This works for me with all of the apps I have purchased including games. Just a note you can pull up the same music control if the iPod is a sleep and locked by pressing the button three times quickly.

Is there a way to show two angles at the same time in the final edit rather than switch between them with Multicam?

Can I show two angles at the same time in the final edit rather than alternate with Multicam?

Stack two clips on top of each other and reduce the sizes. I think that's what you want.

One again, "can I use CC on two computers at the same time?" - in practice.

I know this has been asked before and all those threads are locked. Many asked the question, but I haven't found a satisfying answer yet.
Can I multi task with CC?
I want to have my laptop next to my desktop. And while I render, export or whatever my newly shot documentary on the laptop I want to work with a music video project on my desktop. Then when the render is finished I render the music video and go back to the laptop and continue on the documentary. Or maybe I just work 5 minutes on the desktop music video, then come up with something brilliant for the project on the laptop and switch. Back and forth. Will that kind of activity result in any kind of limitation, usage-wise?
So, working on Premiere on my two computers at the same time.. is it possible? Technically? I know the EULA says "only one person". But will it let one person mutli task?
I need to know this before I buy. sorry for asking this again, please bless me with a clear answer

Hi Jimmy Crim,
Yes in case of Creative cloud subscription you are allowed to install and use the cc apps in any two machines.
Even if you want you care allowed to use these apps together in both the machines.
