Mainstage shows keyboard input, no audio
The program shows midi input from my USB keyboard, but the screen keys don't suppress and no sound comes out. The audio is there when I mouse the screen keyboard.
simple beginner's question, but difficult to find how to assign the midi keyboard to the concert.
RT
Go to layout mode(command>1) and select the keyboard screen control. In the upper left hand corner you'll find the screen control inspector. Assign your keyboard here, either by selecting "assign" or manually selecting it in the MIDI port box. Do the same for pedals attached to the keyboard.

Per Sean Dale1, the following was mis-posted in the 10.5 Leopard thread (original post here: http://discussions.apple.com/thread.jspa?threadID=2201088):
Have been running into this problem more and more frequently on both a MacBook Pro and Mac Pro tower running 10.6.1 and 10.6.2: when I Control-right-arrow to move to my other "space" one or two of two bad things will happen:
(1) the icon in the middle-bottom of the screen showing which "space" I'm in does NOT fade away and disappear
(2) I am prevented from doing ANY keyboard-input into my programs there. I will be able to click and highlight windows using the mouse, as well as see menus activating and such, but anywhere there is a text field (browser or address book or ANYwhere) keyboard input is not displayed.
The only solution is to go into the Activity Monitor and quit the Dock application.
Have been seeing this problem for a few weeks which persists through reboots and such.
Ideas?This issue is being covered in more detail at this thread:

This suddenly started happening to me yesterday and now happens every time I switch Spaces with the keyboard. I've found that the only way around it is to only use the menubar icon to switch. Because I'm so used to clicking keys to switch Spaces and still do it unconsciously, I've disabled the keys in Spaces prefs. -
Maple13, tiling wm and keyboard input
Hi,
I am using a tiling wm (musca). I installed maple and at first had the problem, that maple would show only a grey window.
Using wmname and
wmname LG3D
I resolved the problem. Now the problem is, that the worksheets wont accept my keyboard input.
Mouse/menus work. All dialogs also work with keyboard input.
If I open a new worksheet, input works. But as soon as I switch worksheet it does not work anymore.
Anyone an Idea what I could do?
Thanks!
PS: I already tried sun jre (from pacman) and openjdk6 by changing the maple startup file. It's always the sameDepending in your window manager you may have the option to add a floating workspace. Try working there. If that doesn't solve the problem you can try runing an aditional floating window manager inside a Xnest or a Xephyr session. This has worked for me for some other problematic applications. For example try:
Xephyr -ac -br -host-cursor -noreset -screen 1280x800 :1 &
sleep 3
twm -display :1
this will initiate a new X session inside yours, which will be managed by twm. There you can run a terminal and of course maple. Maybe is a sub optimal workaround, but is the only alternative I have found.
(Note that Xephyr is found in xorg-server-xephyr package and twm, well in xorg-twm ) -

I've finished up a version of Pong for extra credit for a Java class i am taking, and i ran into an interesting situation.
I cannot figure out how to have a two player version of pong have both players control their paddles with the keyboard. The specific problem i run into is, when i enter one paddle to move, and the other attempts to move it stops the first paddle from moving, also there is the whole issue of the key delay that occurs when a key is held down. If anybody can help me out, i would be incredibly greatful.
It seems like it could possibly being done, for example, in games ive played before a character has been able in mid run(holding arrow key) press another key(such as shift) and jump into the air, while still running, to perform a run-jump.
I have tryed setting up a keyboard input test so if both keys are pressed both paddles move. This works for one movement, but have you ever tryed hitting two keys at once in word? they both will display once, their will be that short delay, then one of the two keys will continously repeat.
Any advice? I have it working with one Keyboard input, and the other Mouse input, but the mouse clearly has a big advantage over the keyboard player...
Thanks,
Sean Greenand the repeated key thing still happens as well as the delay....I guess you'll get this as long as you use keyTyped() for player1. Is
there some reason why you're doing this?
What I was thinking of was along these lines:boolean up1, up2, down1, down2;
keyPressedHandler()
if key is w up1=true
if key is s down1=true
if key is up, up2=true
etc
keyReleasedHandler()
if key is w up1=false
etc
drawingCodeOrWhereever()
if(up1 && !down1) player 1 is on the way up
(else) if(down1 && !up1) player 1 is on the way down
if(up2 && !down2) player 2 is on the way up
(else) if(down2 && !up2) player 2 is on the way downYou may want to handle the case of up and down both pressed
differently.
If getting rid of keyTyped() doesn't help, post some code. An example
simple enough to just show the problem woule be good. Say how
you would make a dot move left-right and up-down indepently. -
PPC apps (on intel): slow startup, no keyboard input, Excel-Office crashes
Hello,
It seems, that all apps that are using rosetta don't work properly.
- The startup time is extremely long, some minutes, spinning wheel is visible
- input via keyboard isn't possible
- Office v. X (Word, Excel, PowerPoint) apps are crashing at startup
A test with the Calculator.app switched to open with rosetta showed also this symptoms (no keyboard input possible)
Curiously all this happens *only with my account*. So first I thought it is a problem of the preferences or fonts. But deletion or substitution from backup does not succeed. Also I did the tip sudo "update_prebinding -root / -force" but it didn't help.
I mad up a fresh account and compared all the files in the ~user/Library path, if there is a file missing in the brocken account. But didn't found some.
Is there anywhere a file outside the ~user/library path, which has user dependend informations (for rosetta)?
Many thanks in advance for any idea
GeorgeYeah, I've got it!
In /Library/Caches I found the following files and trashed them. Now all PowerPC application incl. Office v. X are working again. Huh!
(My User ID is 504)
com.apple.ImageCaptureExtension2.ICADeviceDatabase.504

I didn't look for the single fault in any of this files, but maybe someone has an idea, which file is related to rosetta and likes to post it.
Best regards and thanks to everybody who thoughts about a solution for my problem

OSX/SL 10.6.8 all window apps lose keyboard input; mouse and cmd-N work for spaces
Input suddenly stops going to all applications, from MacBook Pro and wireless keyboards, and from "Show Keyboard viewer" (OSX 10.6.8 'Snow Leopard', MacBook Pro). Though the OSX Keyboard Viewer shows the keys onscreen as they are pressed on the MacBook and wireless keyboards. 'Spaces' responds to cmd-N commands, but no input is possible to any running or newly-started 3rd party or Apple-provided application. Killing off applications one by one doesn't recover keyboard input ability; a complete reboot appears necessary to restore the ability to key input into applications. This happens repeatedly, yet never registers as an OS/X 'crash' because 'Force Quit'ting applications and restarting is still possible using only the magic mouse or trackpad. No data whether only logging out and back in would correct the apparent input-focus disconnect of all applications with the window manager. There may be some way to restart the window manager by using the mouse to open up new apps and/or cut and paste characters ( including a carriage return ) or cut and paste entire saved typed commands into a terminal window.
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. 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. When you reboot normally, the initial reboot may be slower than normal. 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 un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Show Keyboard & Character Viewers setting not working
I like to have access to the Keyboard and Character Viewers in the menu bar; however, the setting on my new MacBook does not work. I have checked the "Show Keyboard & Character Viewers in menu bar" many times and it unchecks itself as soon as I leave the Keyboard tab of the Keyboard setttings in System Preferences.
Could a preference file be corrupted? (I migrated data from my old MacBook (OS 10.7) to my new MacBook (10.9). Perhaps this has something to do with the problem?)
Or, is there a command line way to show the preference that might stick better than the checkbox in the System Preferences?
Any insights would be appreciated.
Thanks,

Indeed, the way Apple has done this in Mavericks seems both odd and cumbersome. I think it would be worth telling them so at

Photohop CS6 Update to 13.0.2 breaks keyboard input and shortcuts
Hi,
I just got the new update to 13.0.2 and after installing it Photoshop doesn't recognize keyboard input as expected? Shortcuts are not working anymore. Input values are not recognized. Text editing not possible anymore. etc.
And: When I start Photoshop I get the following trial info:
Master Collection trial. 32767 DAYS REMAINING
Thats over 89 years – I can live with that. ;-)
But there is something wrong with that update, that makes it impossible to continue my work.
Regards
PS: Is it possible to uninstall this update or do I have to uninstall Photoshop at all?Thank you for the quick answer.
Sytem Info tells me …
Optional and third party plug-ins:
Interpolate CS6 (13.0) ©1993-2012 Adobe Systems Incorporated - from the file “Interpolate.plugin”
Match Edges CS6 (13.0) ©1993-2012 Adobe Systems Incorporated - from the file “Interpolate.plugin”
Plug-ins that failed to load: NONE
Flash:
Mini Bridge
Kuler
Installed TWAIN devices: NONE
In the meantime I did a system restart and several Photoshop restarts. Finally some weirdness is gone. Trial mode seems to be gone and Photoshop seems to be activated again.
Two thing left:
1. I do have a text element, for instance, thats acting weird. The screenshot shows two "Login" text items with exactly the same settings for font and size. But they are displayed differently.
Easy fix: delete the weirdo and create a new one. But still worth mentioning, I think.
2. One of my favorite shortcuts is gone. cmd+alt+0 (num pad) to set zoom to 100%
Easy fix: set the shortcut again via Edit > Keyboard shortcuts …
Sorry for panicking, but I was really worried to lose the day looking at installers. ;-) -
Kazakh keyboard input not works
Hi.
I'm can't figure out trouble with kazakh(cyrillic) input to text controls in Flex4.
I'm embedded unicode fonts, and "Copy->Paste" kazakh text from notepad into flash app works fine!
But i need to keyboard input. In my case ordinar cyrillic letters inputs normal, but kazakh-specific
letters (located in keyboard's 1234 and 7890 keys) not works - ? symbol displays.
Please, anyone help me. I'm wasting 2 weeks in attempt to resolve it.
P.S: FlexSDK 4.0.0.12321, FP 10.0.42.34, OS Windows.When you paste and it works, take the string and look at the charCodeAt() for each character in the string.
Then when you type, see if the keyDown event is reporting the same charCode or not.
Another test is to verify that your browser can allow those characters when typed into an HTML INPUT tag.
Hi!
When i'm pasting kazakh letters into textInput, flexApp shows correct charCodes, e.g.:
әіңғүұқөһ -> 1241 1110 1187 1171 1199 1201 1179 1257 1211
but when i'm typing this letters from keyboard, flex shows these charCodes:
?і??????? -> 63 1110 63 63 63 63 63 63 63
(cyrillic-kazakh letters located in place of 2,3,4,5,8,9,0,-,= symbols of keyboard, on simple click - lowercase, with ShiftKey - uppercase).

The red colored "record ready" button has disappeared from my track header area.
The other four buttons are showing fine, (input (i), hide (h), mute (m) and solo (s).
Can anyone help me with this?
Thanks
JohnnyAhrenshof: Thank you for your suggestion:
((preferences>audio>devices (re-select your input source) ))
I already had that done IE. I had duet already chosen as input and output etc etc.
The problem seemed to be the issue that was addressed by Eriksimon:
(( ctrl-click the track Header.))
Following that advice gave me a drop down menu which allowed the various buttons to be
checked and unchecked.
Thanks so much for taking the time out to
help with my problem. It seems to me that
this formum is far better equipped to handle
user's problems than any or the options that
are available on the acual Logic help menu.
It appears that Logic has been put
together by techies who, (though they
may be brilliant at computer software issues), then have
virtually no skill or imagination with regards explaining
how to use it, to the actual users.
I have a PhD in Egyptology. I mention this not
because I think it a particularly brilliant acheivement
but just to indicate that I am not a total dummy.
More to the point I find using Logic needlessly tiresome
and the explanations that are given in the "Help" menu
are nothing short of tragic. Perhaps Apple could start to give
out free ropes or razor blades to everyone who buys the program.
Not to say it is not much better that the other junk out there, it is,
the sorry fact is that that is not saying much at all.
I send sincere thanks to all the users out there who support
each other through this forum. johnnyloonybin -
I am looking for a way to put my gui application in a "wait state." What this entails is that the mouse cursor shows an hourglass and mouse clicks are ignored. Also, any keyboard activity is ignored as well. The reason for this functionality is that there are times that my program needs to perform cpu intensive work and I would like the user to wait until the work is complete before the gui becomes responsive again.
Now, I figured out how to ignore the input from the mouse by using adding a mouse listener to the GlassPane of the gui's JFrame and setting the GlassPane visible. But I can't find a way to use the GlassPane as a "buffer" between the user's keyboard input and the gui. The only alternative that I have found is to add a KeyListener to every component that can receive keyboard input but I would rather not have to manually add a new listener to every single button, textfield, and table that I might have added to the frame. Is there an elegant solution to ignoring or consuming all keyboard activity on a frame that is already set visible? Thanks for your responses.You know, if I read the entire message of the OP, I wouldn't look quite so dumb!
Take a look at the following. It will block and unblock keyboard input.
public class DispatchTest
KeyEventDispatcher blocker = null;
public JPanel buildPanel()
JPanel p = new JPanel(new FlowLayout());
p.add(new JTextField(20));
return p;
public void blockInput()
if (blocker == null)
blocker = new KeyEventDispatcher()
public boolean dispatchKeyEvent(KeyEvent e)
e.consume();
return true;
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(blocker);
public void unblockInput()
if (blocker != null)
KeyboardFocusManager.getCurrentKeyboardFocusManager().removeKeyEventDispatcher(blocker);
public static void main(String[] x)
JFrame f = new JFrame();
DispatchTest t = new DispatchTest();
f.setContentPane(t.buildPanel());
t.blockInput();
f.pack();
f.setVisible(true);

Alternative ASCII characters for standard keyboard input using TextEdit?
Hi, how can slight variations to characters be made on the fly while typing in TextEdit? For example, using Option + O I'm able to type "Ø"...how can I type other "variations" of O...with accents, umlauts, etc? thanks
Choose Show Keyboard Viewer from the menu with the flag icon. If it doesn't appear, open the International pane of System Preferences to enable it and the input menu.

Keyboard input changed to wrong language
I'm using a dual g5 desktop running tiger 10.4.4. This morning all keyboard input is in the wrong language. It's greek or one of the symbol fonts. According to the setings in the international panel everything should be set to US English, roman script. I know that CMD+space used to toggle between input choices but that now brings up Spotlight. Is another key combination that toggles the languages? Other settings to check? It's interesting that the input menu tab of the international pane still says use CMD+space to toggle inputs, but that no longer works.
Help? thanksAccording to the setings in the international panel
everything should be set to US English, roman
script.
The setting that matters is system preferences/international/input menu (not languages). Also make sure you have the box checked for "show input menu in finder," so you can see what keyboard layout is active in the "flag" menu at the top right of the Finder.
