Choosing a basic 88 key keyboard and latency

Please bear with a newbie's question.
I'm thinking about buying a very basic 88 key keyboard to get back to playing the piano (after 40+ years). All I'm really interested in is one that will just play sounds like a piano. My musical tastes are 99% classical. I don't have much interest in loops, creating my own music etc.
On another forum, someone suggested that latency might be an annoying problem. I have a G4 and wondered if latency will be an issue or what steps/tests can I take to establish if this might be a problem.
Many thanks.

I'm not sure I understand the problem/question.
Latency problems are usually related to processor intensive tasks like high track counts or plug-ins such as complex reverbs. If you are simply looking to get a piano sound, latency should not be an issue.
Keyboard choice should also not be an issue from a latency standpoint. Any midi keyboard will transmit the same midi data... one model vs. another will not affect latency. Unless I am completely misunderstanding, latency should not be a concern for what you want to do.

Number pad on 10 key keyboard and Windows

For some reason, my 10 key does not work on my keyboard on the Windows (XPSP3) partition. Anyone know of a button to use to turn on the number lock on it? It currently works as if the number lock is not on.
Thanks

Hi,
for activation of number keys you usually have to press the so-called 'clear'-key.
It's the one directly above the '7'-key of the number pad.
And you usually have to do that only once, as Windows 'remembers' that setting.
In Windows it's called the 'NumLock'-key.

Getting a cmd key on an external 101-key keyboard

I'd like to use my classic IBM Model M keyboard with my new MacBook Pro. I've connected the keyboard into the MacBook Pro via a PS/2-USB adapter and am able to type fine and enjoy all of its old-style clicky, mechanical key goodness.
The problem is, however, that there is no cmd/flower/Apple key on an old 101-key keyboard -- and this key comes often comes in handy in OSX.
Is there any way to simulate the cmd key in OSX? Or can I perhaps reassign another key to work as the cmd key? I do have at the top of the keyboard "Print Screen", "Scroll Lock", and "Pause" keys, which according to keyboard viewer, work as F13, F14, and F15. F14 and F15 work as screen brightness up and down and F13 has no function. Could I perhaps assign one of these keys to work as the cmd key?

*Modifier Keys* will indeed allow me to assign the Caps Lock, Control, or Option/Alt key to be the Cmd key -- but then I'm out either a Caps Lock, Control, or Option/Alt key.
Well, I decided I can live without a "Caps Lock" key better than I can live without a "Cmd" key, so I swapped away my "Caps Lock" for "Cmd" in "Modifier Keys".
It's functional for all the cmd-key combinations, but alas, it does make it HARDER TO SHOUT LIKE A N00B ON MESSAGE BOARDS.

New Apple Keyboard and Insert Key

I'm using the new Apple Keyboard (http://www.apple.com/keyboard/) and I'm quite happy with it. The only big disadvantage is the missing Insert-Key, the Apple Keyboard has a function (fn) Key, where the insert-key is normally located. I need the insert-key especially for selecting in midnight commander. What would be the best way to remap the insert-key to the fn-key for console and X-Windows?

Here are some relevant other threads:
http://bbs.archlinux.org/viewtopic.php?id=56619
http://bbs.archlinux.org/viewtopic.php?id=55482
These are just threads I've participated in; I'm sure there are more. The bottom line is: check with showkey (in the Linux console) or xev (in X) to see how the fn key is getting recognized. If it's working just like another key on the keyboard, e.g., like space or shift, then you can remap it the same way you'd remap any key. (The process is different for Linux console than for X.) But most likely it's not working just like another key on the keyboard, in which case it will be difficult/impossible to remap it to insert. However, you could always choose another key, or key combination, to remap to insert. Perhaps even a key combination of the form fn+KEY. The kernel won't recognize fn as a modifier like shift or control, but it should recognize SOME fn+KEY combinations as being SOME keyboard keys. For example, on my keyboard fn+left arrow is recognized as Home. I think that as far as the kernel and all the key-remapping tools can tell, I only pressed Home on my keyboard not any combination including left arrow.

I have a Macbook Air that had some coffee spilled on the keyboard and as a result the plus/equals key is no longer functioning. Can I use a program like Ukelele to reprogram a different key to be my plus/equals key? Can I program a function key? key

Water + electronics do not mix. Something was damaged insode, and the logic board may be corroding as is.
Take it to a Genius Bar for an evaluation and repair estimate.
This is accidental damage and not covered by warranty.

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows). The key behaves the same for the laptop keyboard and for an external Apple keyboard? This just started in last week after 6 months of use

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows).
The left shift key behaves the same on the laptop keyboard and on an external Apple keyboard.
This just started in last week after 6 months of use. The right shift key and other keys on the keyboard all appear to work correctly.
Suggestions greatly appreciated.

I have a solution to this issue now after a discussion with Apple Support. Some where in the last few weeks, there was a change in the key that would do a Show Desktop under the Mission Control settings in the System Preferences. Even though the key sequence that was shown for the Show Desktop setting did not include the Left SHift key, by changing this first to having no key sequence and applying that and then changing it back to the F11 key, the Left SHift key issue that I was having has cleared up.
A second issue that was uncovered was that the SSD had some issues (uncovered when I ran Disk Utility using the Repair Disk key). I had to restart and use the Disk Utility through the Command R sequence to get to the stand alone Disk Utility. The SSD appears to be running better as a result as well.
Hope that this is of use to someone else in the future.

When I disable my left windows key for gameing using Microsoft keyboard and mouse software, I can no longer type in firefox. How can i fix this?

Microsoft Keyboard and Mouse Software that you install with Microsoft keyboard and mice, (latest version) allows you to disable your windows key so that you don't accidentally hit it when gaming. When I take advantage of this feature, I can no longer type in Firefox. Typing in Firefox is completely disabled. Other browsers, windows, applications work, but not Firefox. What is it about the windows key that firefox needs for typing. Strange problem, but annoying because I have to use a different browser while game. Certainly not a deal breaker, but kinda strange.

"new selection", restricted key figure and basic key figure

Hi,
I have a test report and i have a basic keyfigure "ZRevenue" and "restricted key figure"(its defined over "ZRevenue") and
a "new selection"(its defined over "ZRevenue").
Now that i have "material number" and "material color" and "request id" in the rows. ("Material color" is a navigational attribute of material number).
In the column level i have a basic key figure "ZRevenue" and "restricted key figure"(its defined over "ZRevenue") and
a "new selection"(its defined over "ZRevenue") .
In a "restricted key figure" or "new selection", we can include a basic key figure or new formula or calculated key figure or an already restricted key figure into it, then we restrict it, with one or more characteristic values. In the report output we get KF values only for those characteristic values, with which it has been restricted. Please correct me if my understanding is wrong.
Initially i restricted the "new selection" (with material number 1 to 3) and "restricted key figure" (with material number 1 to 4).
In the cube i have material numbers 1 to 11. Now all the values were displayed from 1 to 11, but for the
"new selection" (with material number 1 to 3) and "restricted key figure" (with material number 1 to 4) i got values only for 1 to 3 and values for 1 to 4 respectively. This is as expected and is working fine.
Now i tried to restrict the basic keyfigure "ZRevenue" with material number 1, the output was only until the material number 4 (this is the greatest value of the material number defined over the "restricted key figure").
Then i tried to restrict the "new selection" (with material number 1 to 9) , then the output was from 1 to 9 material numbers.
If i remove the restriction over the basic keyfigure "ZRevenue" , then i get all the material numbers from 1 to 11, for "new selection" i get values for the material number 1 to 9 and for "restricted key figure" i get values for the material numbers 1 to 4.
Can some one explain me why this behavior?

Hi,
This is where set theory comes in handy
So what you have is a basic KF (BKF), a selection (SEL), and an RKF.
When producing an output, BEx seems to be looking for the union of all the restrictions you place on these. So when your BKF is not restricted, the union comes out to everything in the underlying DSO. When you restrict the BKF for material number 1, this is how the restrictions might have been processed internally
BKF: Restriction on material 1
RKF: Restriction on material 1-4
SEL: Restriction on 1-3
Union of these three: 1-4
When you remove the BKF restriction and make SEL restricted to 9, this is how it plays out
BKF: NO Restriction on material
SEL: Restriction on material 1-9
RKF: Restriction on 1-4
Union of these three: everything.
As the union ends up giving you everything, you get 11 records. However, as SEL is restricted for 1-9, the SEL will have values for the materials 1-9. Likewise for RKF, you'll get values only for materials 1-4. Hope this clears things up!

Suhas

Mapping keyboard and mouse keys onto my gamepad

Have you tried using xbindkeys?
Do

External keyboard and modifier keys

I like to swap my "Ctrl" and "Command" modifiers keys and I've never had a problem doing this until upgrading to Lion. If I disconnect and reconnect my external keyboard sometimes my modifier keys are reset.
Lion lets you change modifier keys per keyboard which is where I think the problem lies. I also have duplicate listings for my external keyboard and I'm not sure how to delete the duplicates.
Does anyone know how to fix these issues?

Also, I'm not sure if it matters but my mouse and keyboard are connected through a USB hub which then connects to the Macbook Air.

How to create Basic Key Figure, Key Figure and Characteristic

Hello Gurus,
I have copied a standard layout of KP06, named it as a Z- layout and made changes to it, like defined the plan data upload field as Object Currency enabled.
However I want to add a Z-Field , tax holiday unit as a column to this layout which I am not being able to do. The reason is when I go to Insert a new element from Edit > Element > Insert Element and click on 'Key figure with Characteristics' I do not get the Z-Field as a key figure.
I want to define the Z-field as a key figure, so that I can add it as an element.
Would be really nice of you if you can let me know the t-code/menu path to do that.
Regards.

Hello Gurus,
I wanted to share this information with you, hoping this will help you to help me.
I also tried to create a Key Figure in t-code GS32. In the table I mention --> FAGLFLEXR and hit enter. It says no Key figure has been defined for FAGLFLEXR. Then I put the cursor on the 'Reference Entry'and click on copy. Then give the name of the Key Field I want to create.
'Create Key Figure' dialog box appears. When I input the 'Row Text' 'Column Text' and click enter, I am getting an error 'The basic key figure entered for table FAGL is not defined'. I go back and do an F4 on 'Basic Key Figure' field, then I do not get any options.
I would be highly grateful if you can let me know how to create this 'Basic Key Figure' for table FAGLFLEXR.

MacBook stuck with shift key enabled and numbers not working - even the keyboard app in languages wont type lowercase nor numbers?! Anyone know whats up? no spillage...cant understand why the keyboard app wont do anything.

Anyone have a clue? I can understand the keyboard being broke / shift key being stuck but why in the world would I not be able to type the numbers on the language keyboard app on the operating system? Numbers show up on the app but when I press them I still get the special characters like #^&#* and it wont type lower case. Nothing has ever been spilt, just stopped working one day. Rebooted from Time Capsule restore dated a month ago and its still doing it. (problem started two weeks ago). Only way to get lower case or numbers to actually show up is the copy and paste.
Any help would be amazing!
Details on computer: 13 inch MacBook6, 1 (Late 2009) / Intel Core 2 DUO / 2.26GHZ / 2GB / Memory running Mac OS X Lion 10.7.5

If you can afford it, I would recommend replacing the topcase and keyboard as Apple suggests. If like me, you can't afford it or are open to a hack fix, then read on.
The problem
Yesterday, a little water spilt on my 13" MBP keyboard. I turned it around immediately, drained out the water and used tissue to suck it all up but the keyboard was still acting funny. I turned it off and left it out in the sun for a couple of hours and turned it on again but problems remained. Like Rickdubya, my warranty had run out just a month ago and I knew Apple would not cover this under warranty. I tried to clean the shift keys and left it overnight with some rice on them with hopes that the moisture might get sucked out. Nothing worked. (The rice bit is an urban legend that seems to work with some electronics). Went to the Apple Store this morning and was told that they wouldn't even take out the key and clean it, and that the entire top case would have to be replaced. A total bill of 156 Euros which I cannot afford. I had a USB keyboard that would let me use the Mac for the moment so I decided to try to work out a fix.
Symptoms
- Boots in safe mode everytime (which I later found out was because the shift key is pressed)
- Cannot login because password is in lower case or has numbers
- Cannot boot in super user mode and try to disable keys or override password as some commands won't work in uppercase (I wouldn't recommend this anyway because its super user mode)
- All text is in caps and numbers are symbols as though shift key is always pressed
- Audio doesn't work
- Keyboard viewer would not always show the shift key pressed. The key seemed to get pressed at random
Fix
1. Hold the Option button down on boot to bypass the Safe Mode ensure a normal boot
2. At the login screen, plug in a USB keyboard and enter your password to login
3. Change your password to one that uses all caps and no numbers
4. Download and install KeyRemap4MacBook .
5. Use a combination of the functionalities of the Keyboard Viewer and KeyRemap4MacBook to figure out which shift key is the problem. In my case, I found out that it was only my left shift key.
6. Disable the left/right shift key on KeyRemap4MacBook and click on the 'Reload XML' button to make that take effect.
If only one shift key was the problem, then you are done. If both shift keys were shorted, then its likely other keys are too. In which case you should probably just replace the entire thing. If you think other keys are not affected, then you can use KeyRemap4MacBook itself to remap the shift functionality to a lesser used key like the Left Option key.
7. Under System Preferences > Users & Groups > Login Items , add KeyRemap4MacBook as an application that should start on login. This will ensure that your disable/remap of the shift key is active everytime you login.
Usage change/Things to remember
1. Remember to hold down the Option key everytime the computer boots or reboots to bypass safe mode. The fix above is at the software level. The key is physically still shorted at the hardware level and will affect boot.
2. Remember that at the login screen, the disable/remap is not active. So your password now has to be all caps and only letters.
As soon as I can save some money, I will get my topcase and keyboard replaced but until then this solution works great with minimal change. Hope this helps!

Hi, some of the keys on my mac book air aren't working e.g. Hyphen, colon but others such as question mark, full stop are fine. Does anyone know how to fix. My toddler pressed some keys on keyboard and this is the result!

You may have this sorted out by now - but if not try resetting your Language to English. I had the issue and found the emoji keyboard was set to spanish.
