How can I properly install my MIDI keyboard?

Hello,
I recently bought an iMac and I still have trouble figuring some things out. For example how I can install my Keyboard. It's a Yamaha PSR 1500. I bought Cakewalk MIDI cables so I could use my keyboard on my computer. I had an Acer laptop before and everything worked good. I've installed the program, but I have trouble getting it to work. I had to connect my Keyboard to my iMac with the MIDI/Audio configration, but I have no clue how it works. In the book there's a whole different Setup than I have on my iMac.
This is a printscreen of the Audio/Midi I have. Does anyone know how I can get my MIDI to work on this? Help would be very much appreciated.

[SOLVED] How to stream audio output over wifi?

Hello,
I have following problem. I would like to listen to the music from my laptop on my home Onkyo AV receiver (amplifier). Both laptop and receiver are connected on the same network, laptop via wifi, receiver using LAN. Receiver is capable to play internet radio streams in various format - e.g. ogg or mp3.
My idea is to produce ogg stream on laptop and listen to this stream through amplifier. I was searching for this solution a found something that has always some disadvantage, like MPD + MPC (can play only from database of local files, not from jamendo or other network services), DLNA can play only local files, Icecast + Ices can play from predefined playlist.
My idea is to have something independent - something what takes audio data normally played on soundcard and feeds it to network stream, something what can work with any player - audio or video, or even with desktop notifications.
Does anybody here know how to do it?
Thanks!

Thank all of you for your hints. Finally I have decided for ALSA based solution that simply works for all applications smoothly in background and it is here when I need it - in other words, it is something that doesn't borther me when I do not need it. I use ALSA loopback with ffmpeg and ffserver for streaming in mp3 format.This is my final solution:
You need following:
alsa
ffmpeg
if you use KDE4, then you need phonon-gstreamer backend, as in my case phonon-vlc didn't work (it was heavily distorted)
Procedure:
Modprobe snd-aloop (2 loopback channels are enough)
modprobe snd-aloop pcm_substreams=2
For permanent solution follow arch wiki https://wiki.archlinux.org/index.php/Modprobe
Create ALSA configuration file and store it either to ~/.asoundrc (just for user) or to /etc/asound.conf as system wide:
pcm.!default {
type asym
playback.pcm "LoopAndReal"
capture.pcm "hw:0,0"
hint {
show on
description "Default with loopback"
#"type plug" is mandatory to convert sample type
pcm.LoopAndReal {
type plug
slave.pcm mdev
route_policy "duplicate"
hint {
show on
description "LoopAndReal"
pcm.mdev {
type multi
slaves.a.pcm pcm.MixReal
slaves.a.channels 2
slaves.b.pcm pcm.MixLoopback
slaves.b.channels 2
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
pcm.MixReal {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
#rate 48000
#rate 44100
#periods 128
#period_time 0
#period_size 1024 # must be power of 2
#buffer_size 8192
pcm.MixLoopback {
type dmix
ipc_key 1025
slave {
pcm "hw:Loopback,0,0"
#rate 48000
#rate 44100
#periods 128
#period_time 0
#period_size 1024 # must be power of 2
#buffer_size 8192
You can play with sample rates and buffer sizes you you have any problem. This configuration works on my system.
Prepare ffserver configration and store either to default location /etc/ffserver.conf as system wide setup or anywhere to your home:
# Port on which the server is listening. You must select a different
# port from your standard HTTP web server if it is running on the same
# computer.
Port 8090
# Address on which the server is bound. Only useful if you have
# several network interfaces.
BindAddress 0.0.0.0
# Number of simultaneous HTTP connections that can be handled. It has
# to be defined *before* the MaxClients parameter, since it defines the
# MaxClients maximum limit.
MaxHTTPConnections 2000
# Number of simultaneous requests that can be handled. Since FFServer
# is very fast, it is more likely that you will want to leave this high
# and use MaxBandwidth, below.
MaxClients 1000
# This the maximum amount of kbit/sec that you are prepared to
# consume when streaming to clients.
MaxBandwidth 1000
# Access log file (uses standard Apache log file format)
# '-' is the standard output.
CustomLog -
# Suppress that if you want to launch ffserver as a daemon.
NoDaemon
# Definition of the live feeds. Each live feed contains one video
# and/or audio sequence coming from an ffmpeg encoder or another
# ffserver. This sequence may be encoded simultaneously with several
# codecs at several resolutions.
<Feed feed1.ffm>
# You must use 'ffmpeg' to send a live feed to ffserver. In this
# example, you can type:
# ffmpeg http://localhost:8090/feed1.ffm
# ffserver can also do time shifting. It means that it can stream any
# previously recorded live stream. The request should contain:
# "http://xxxx?date=[YYYY-MM-DDT][[HH:]MM:]SS[.m...]".You must specify
# a path where the feed is stored on disk. You also specify the
# maximum size of the feed, where zero means unlimited. Default:
# File=/tmp/feed_name.ffm FileMaxSize=5M
File /tmp/feed1.ffm
FileMaxSize 200K
# You could specify
# ReadOnlyFile /saved/specialvideo.ffm
# This marks the file as readonly and it will not be deleted or updated.
# Specify launch in order to start ffmpeg automatically.
# First ffmpeg must be defined with an appropriate path if needed,
# after that options can follow, but avoid adding the http:// field
#Launch ffmpeg
# Only allow connections from localhost to the feed.
#ACL allow 127.0.0.1
</Feed>
# Now you can define each stream which will be generated from the
# original audio and video stream. Each format has a filename (here
# 'test1.mpg'). FFServer will send this stream when answering a
# request containing this filename.
# MP3 audio
<Stream stream.mp3>
Feed feed1.ffm
Format mp2
AudioCodec libmp3lame
AudioBitRate 320
AudioChannels 2
AudioSampleRate 44100
NoVideo
</Stream>
# Ogg Vorbis audio
#<Stream test.ogg>
#Feed feed1.ffm
#Format ogg
#AudioCodec libvorbis
#Title "Stream title"
#AudioBitRate 64
#AudioChannels 2
#AudioSampleRate 44100
#NoVideo
#</Stream>
# Special streams
# Server status
<Stream stat.html>
Format status
# Only allow local people to get the status
ACL allow localhost
ACL allow 192.168.1.0 192.168.1.255
#FaviconURL http://pond1.gladstonefamily.net:8080/favicon.ico
</Stream>
# Redirect index.html to the appropriate site
<Redirect index.html>
URL http://www.ffmpeg.org/
</Redirect>
This sets ffserver for streaming in MP3 format, stereo, 320kbps. Unfortunately I haven't succeeded with OGG Vorbis streaming.
Now you have all configuration you need and if you want to stream following two commands do that:
ffserver -f ffserver.conf
ffmpeg -f alsa -ac 2 -i hw:Loopback,1,0 http://localhost:8090/feed1.ffm
You can test it for example by mplayer:
mplayer http://YourLinuxBox:8090/stream.mp3
And that's it. Sound is played by normal sound card and sent to stream simultaneously. If you do not want to listen sound from computer you can mute your soundcard. It has an advantage that one can normally listen to music on the computer with or without streaming and in both cases without any reconfiguration. To start streaming just call ffserver and ffmpeg.
Advantages:
+ very simple solution without any special sound server
+ no special SW required (in my case I had already instaled all I need for that)
+ streaming on request by two simple commands
+ normal soundcard function
+ streaming in MP3 format that is supported by many home AV receivers
Disadvantages
- phonon-vlc backend not compatible (also VLC does not work)
- OGG streaming does not work
- some latency (~ 5 sec)
- all sounds are sent to stream, including various desktop notifications (in KDE could be managed by phonon)

Unable to capture audio

Hi,
Last week I updated the drivers for my Blackmagic Multibridge extreme. Now when I try to capture the material in FinalCutPro 5.1.4 I can see the picture, hear the sound on my monitors (they are connected directly to Multibridge), but the captured material doesn't have sound, because it takes the sound from the internal audio input. I tried to capture from Blackmagic Deck Control (an external application) and it works fine, it captures with sound. So I suspect I have to change the audio input in FCP, but dont know where. In audio/video settings in FCP everything is set to DeckLink (Multibrige extreme).
Where is the problem?
Thanks,
Simon

Thanks for the reply.
Looking at system preferences I found that audio input was set microphone. Don't know how it happened. I switched it to DeckLink and now FCP displays 16 input channels in Log and Capture dialog. I didn't try to capture yet but I think it solved the problem, because before I had only two channels displyed.

Unable to capture audio from BlackMagic HD Extreme via Voice Over tool

Hi !
I'm trying to capture audio via my BlackMagic HD Extrem card using the Voice Over tool in FCP6, but I can't, no audio is incoming.
I can ingest audio with video using log and capture, then I know my card and my cables are working.
I tried to set the BM card as audio input in my Audio's System Prefereces Pane, but it isn't working either.
I've been looking on the BM website, but I found nothing.
Can you help me ?
Thx

Thanks for the reply.

Unable to capture 2 audio tracks

FCP refuses to capture 2 audio channels?! I have one mic on channel 1 and another mic on channel 2 but FCP captures only 1 mono track eventhough in Clip Setting both channel 1 and 2 are selected. Does anybody know what could be wrong?
Another thing is that when I have captured a clip - it won´t appear automatically in the Browser as it always has done? Now I need to import the Clip from my Project folder. FCP going crazy.

Audio malfunctioning on hp ultrabook?

Hello! So i just recently got a laptop in late june almost early july.
Its a HP ENVY touchsmart 4 Ultrabook
Its not even 2 months old and the speakers on here suck. They kida slurr and like lag. Its stutters really bad. I can't listen to 1 song without it doing that. And sometimes it freezes but only very quickly. And also my down arrow button came off like within 2 weeks.
This is my first Laptop so im not sure if i can return this and get a new one because its audio is malfunctioning and stuff? I have a one year warranty on this.

Hello Gurjot24,
If you want to return it rather than getting it fixed, please contact HP support over the phone to see what options are available.
If you are in the US or Canada the number is 1-800-474-6836, if you reside in a different location click on this link. Click on your country, then click “technical support after you buy”, and the number will be provided.
I hope everything works out.

How do I use my web cam to record audio and video? I can get the video to work but no sound.

I want to record both audio and video at the same time. The video works fine but not the audio. I do use Skype without any problems using both.

PwmBoat,
This made me smile, because things like this do make me smile... I never make videos on YouCam, but I did this time, so I could test this one out.
You did not say what webcam software you are using...
======================================================================
Video and audio recording works on YouCam V3.5.1.4606
Make sure you have turned on a working microphone in Settings:
YouCam > Right-Side Settings >
Right-Side, Lower-Right, Select a working Microphone from the Drop down list
AND
CHECK "Capture with audio"
OK
You can also buy (for $38 US) YouCam 5.0 from the Cyberlink.com website and it has audio/video and all sorts of other goodies, too. (They have 3.x as well, but why buy what HP already gives you?)
==========================================================================
I hope this helps!

Yes it is done through iTunes. The iPhone will never show up in Finder as a device. The following is general information on iTunes sync: http://support.apple.com/kb/HT1386 and the following is a previous discussion where the post by Andreas Junge helped others that had a problem syncing audiobooks: https://discussions.apple.com/message/20052732#20052732

Why does GarageBand audio work for guest user but not my account?

Hello, I have a 15-inch MacBook Pro (2.2 GHz Intel Core i7, 4GB 1333 MHz DDR3) from late 2011 that I bought brand new in 2012. I'm running OS X Mavericks 10.9.4 and my MacBook has 500 GB of storage.
About a month or two ago I tried to download the new GarageBand (10.0.2) but I had trouble completing the loops download. The download would stop halfway through because of a network error. So last week I decided to try to download it again, and I was able to do so after reading some discussions about the issue. I successfully completed the download in safety mode and then I restarted my MacBook. At this point I was able to open GarageBand 10.0.2 and create a new project. Unfortunately, there was no audio coming through the output and sound bar for the various audio components in GarageBand. I had no audio when previewing the loops or playing it back in an audio track. I didn't really test anything else out because I figured I needed to fix this problem first. I have read many discussion boards about audio problems with GarageBand. I have already made sure everything is set properly in the GarageBand preferences and the audio preferences in system preferences. I've tried restarting GarageBand and restarting the computer.
This evening I found a discussion from the username icewhatice and they seemed to have had my exact problem. I'm not sure that I found the answer on this discussion though. For reference, this is what icewhatice posted: "I have no audio coming from Garageband 10.0.2. Downloaded it on Saturday and have spent the last two days trying to figure out why it won't work. I'm using a macbook pro with an Alesis QX49. GB registers keyboard when I plug it in but no sound whatsoever, not even from the onscreen keyboard. It seems to read the keyboard as if I play a C chord, it appears in the display. I've done all the obvious stuff like check preferences, restart, I've deleted and downloaded new GB several times and always with same result. Actually, it took me about four attempts to download it in the first place as I was getting an internet connection error message right at the end of the download, and I see others have had that problem. Managed to solve that by downloading in safe mode but now the no sound thing is driving me absolutely crazy because I can't play my keyboard!!!!! Also, worth noting that there is no audio level being read anywhere, I believe in the new version this appears in the volume control at the top. I've also looked into it potentially being a problem with my keyboard and it possibly needing an update but can't find any difinitive answer for that anywhere. I've stopped looking into that because the on screen keyboard doesn't even work - if that worked then I would know at least GB works and it's something to do with the keyboard. So, I am at a complete loss. If anyone has any ideas about why this is happening or what I could do to solve then I would be very grateful."
After reading this, I realized that I am unable to create new tracks, and I realized that I have the same problems with old projects saved from the last version of GarageBand I had. I have not tried to download GarageBand again since it did not work for icewhatice. léonie ended this post by saying: "Something is certainly wrong - either the current project, some settings in your user account, or the downloaded GarageBand version. Or incompatible software may be interfering. If a new project does not work, try to test by logging into a different user account, for example the "Guest User" account. Create a new project using this account. Does GarageBand work better from this account? Then we will need to troubleshoot your preferences."
I have tried this and started a new GarageBand project in the "Guest User" account. GarageBand was working fine in the "Guest User" account and all of the audio was working properly. Does anyone know how I should troubleshoot my preferences?

If an application is working in a different account, but not in your regular account,try t find out, what you configured differently in your own account, for example start-up items or preference panes you are using, applications and other helper tools, that are only installed for your regular account. As a first guess, remove GarageBands preference files from the user library in your Home folder.
But you will have to reset all settings you did in the GarageBand preferences dialog. And GarageBand will not remember the last project. You'll have to find the file manually.
Remove these files from your User Library to a folder on your Desktop:
~/Library/Containers/com.apple.garageband10/
~/Library/Preferences/com.apple.garageband.plist
~/Library/Caches/garageband
Quit GarageBand, then remove the files to a folder on the Desktop and restart the computer, before trying again to open GarageBand.
You user library may still be hidden, as is the default in Mavericks: To open your hidden user library:
Select the "Home" folder icon (the little house) in the Finder's sidebar and press the key combination ⌘J to open the "view options".
Enable "Show Library Folder".
Then open the Home folder and open the Library folder inside and navigate to the Preferences, Caches, or Containers folder. Remove these folders completely - don't leave anything inside: ~/Library/Containers/com.apple.garageband10/,
~/Library/Caches/garageband .

Does the mini DVI port cary audio if using a Mini-DVI to HDMI Adapter?

Hello everyone,
I've heard it is possible for a DVI port to transmit audio data to a HDMI connection if a DVI to HDMI cable is used, which will allow the sending of both audio and video to your TV. see: http://en.wikipedia.org/wiki/DigitalVisualInterface
I'm assuming this is not possible using apples mini DVI port, but just wanted to check to make sure. My main goal is to get surround sound out of my powerbook. To do this by simply adding a Mini-DVI to HDMI Adapter would be GREAT!

Hi Jonathan,
I'm assuming this is not possible using apples mini DVI port
Yup, no audio, unfortunately. The audio will have to transmitted separately via the analog audio output.

How to connect sound or audio to my tv using hdmi adapter. I tried to connect thru sound settings but my tv is not found.

how to connect sound to my tv set using hdmi adapter. Im using 2009 macbook pro 13". I went to sound settings then output and it shows internal speaker built- in, it wont locate my tv set. pls. help, thanks

You probably can't because it looks like your MacBook Pro is too old to carry audio over HDMI. You will need to run a separate audio cable from the audio out port on the MacBook Pro to the audio in port on the TV.
Check your MacBook Pro model year against the list in this Apple tech note:

The yellow RCA jack is called "NTSC Analog Composite Video", or "Video" for short. You need an adapter to "Video".
Exactly which MacBook Pro (or which output Display Port) do you have?

Need help to open audios attached in a PDF file

Hello
I just need help. I have ordered a reviewer online that has audios and texts in a pdf file. I was told to download the latest adobe reader on my computer. I have done the same thing on my ipad mini. I am not so technical with regards to these things. Therefore I need help. I can access the audios on my computer but not on my ipad.
I want to listen to audios with scripts or texts on them so i can listen to them when i am on the go. I was also informed that these files should work in any device. How come the audios doesnt work on my ipad.
Please help me on what to do.
Thanks

Audio and video are not currently support on Adobe Reader. :-<
You need to buy a PDF reader that supports them. My suggestion is PDF Expert from Readdle ($US 9.99)

How can I display & split the audio & video from the same digitized clip?

I digitized a scene into iMovie that I edited on a professional system which I don't have access to anymore. The whole scene is 1 clip. Now I see a few tweaks that I want to make, so I was hoping to do them in iMovie.
I want to "pull up" the audio in one section - meaning I want to take cut about 20 frames of audio from the end of a shot, and then move all the other audio up to fill the hole. To compensate for the missing 20 frames, I'll cut video off the head of the next shot. Some call this prelapping. Some call it an L-cut. Some call it asymmetrical trimming. Either way, I can't figure out how to do it in iMovie.
My clip appears in the timeline as one track - a single track that contains the video and 2 audio tracks. How can I display the audio that's tied to the video on its own track? Then I think I could split audio & video wherever I wanted and trim things up - but I can't figure out how to do it.
Am I asking too much of this software?
BTW, I never see the option to "Split audio clip at playhead". I'm not displaying clip volume or waveforms. Choosing to display waveforms doesn't show me anything. Maybe iMovie thinks I'd only want to see waveforms of audio that isn't tied to my video-and-audio clips?
Thanks in advance for any help...

Jordon,
"Am I asking too much of this software?"
No, you're not.
You first want to select your clip(s) and choose Advanced>Extract Audio.
This will copy the audio from the video clip and place it on one of the two separate audio tracks while lowering the audio level to zero in the original video track.
You can now edit and move the audio independently of the video.
With the audio clip selected, you'll find you now have access to Edit>Split Selected Audio Clip at Playhead.
