Learned controller assignments often get stuck in Logic.... (?)

Hey guys, when use hardware controllers for controlling parameters of softsynths in Logic, I find that the software knobs often get stuck while moving them. I can not see a pattern to this behaviour, but it happens if I learn assignments within Logic, or using my Novation remote SL and other controllers with templates.
Is this a known issue. Anyone else getting it?
thanks,
Rob

Yeah the whole controller assignment thing has me
baffled. It seems to be geared towards specific,
permanently installed "control surfaces".
Not really - you can completely create your own multi-layer control surfaces, it's just that doing a complete control surface, with bank shifts for controlling track groups and so on is a fair amount of work, and takes some getting to know the controller assignments window, and the terminology like "modes" and "zones" etc
However, the level of control it gives you is great, and if you want examples, you can for instance load a Logic Control controller surface into Logic and examine the way all it's assignments are configured.
If you want to be more sure you can set up a
transformer object to map midi cc's to your synths.
I find it's way better (for me at least) to develop my own control surface support. I use a Korg MicroKontrol and found the default controller support to be rather clunky and not ideal for me, so I've developed and been refining my own control surface support which suits my needs perfectly. It's takes time and is an ongoing process, but is highly useful.
I just wish some of the flaky behaviour was fixed, but my fingers are crossed for future versions...
In any case, if you want to map a fader to a softsynth parameter, just hit apple-L, click on the onscreen control, and twiddle you fader. Assignment learnt. Do this for the parameters you want, turn off learn mode, and twiddle away with perfect automation.
Don't also forget the automation quick access as well - assign your mod wheel to this, and you can select any parameter of a plug and quickly use the mod wheel to control it or write automation etc.

My camera often gets stuck or says "camera not available" what's the problem? What should I do?

My camera is not working properly. It often gets stuck or says " camera not available" and if I take video via manual mode it gets stuck with a photo but the video is being taken. What's the problem?

Pinch zoom is often getting stuck and going to the full extent of zoom since Yosemite upgrade

Are any other users experiencing an issue where pinch zooming is broke since upgrading to yosemite? When I use the two-finger pinch zoom, the zooming often seems to get stuck and keeps going after I lift my fingers. Whether zooming in or out, the zoom will often continue to the full extent of zoom capability in whichever direction it started. Tapping on the trackpad while it is in runaway zoom has no effect and I just have to wait for it to finish, then resize things manually. Is anyone else having this problem? I did a fresh reinstall of Logic but that didn't help any.

IOS apps often get "stuck" while installing- fix?

Summary: When downloading an app it will sometimes get "stuck" on the last step of installation. The progress bar is complete, but it says "Installing" for a long time after that, often requiring the device to be restarted.
Steps to Reproduce:
1. Download or update an app from the App Store. (The Target app for iPhone is one I've had this problem with, though it doesn't seem to be app-specific.)
2. Wait for it to install.
Expected Results: The app should finish installing shortly after the progress bar is full.
Actual Results: Sometimes it continues to say "Installing" long after the progress bar is complete. I've had it stay this way for as long as 15 minutes before giving up and restarting the device. As soon as I restart, the app is installed, though usually in a different location than it was previously. Other times the install will successfully complete after simply waiting a few minutes—longer than normal but with no extra action required.
Regression: I first noticed this problem recently in iOS 4.3, though another user told me it happened in 4.2.1 for them. This makes me wonder if it's related to a recent App Store change, rather than a change in iOS itself.
Notes: I haven't found a way to reproduce the problem reliably, but I've had it happen quite a few times
Anyone else?

your problem is not very unusual... I also faced the similar situation cpl of times when Oracle was not able to continue the installation coz the Immediate Shutdown was failed. Actually During the installation, Oracle mounts/opens the database and shuts it down many times and few times, Oracle is unable to shutdown cleanly as some process is hanging or not responding.
Piece of advise is that always use staging area to install Apps as it takes long time on Win2K (anything between 4-12 hrs) to install it and CDROM Access is lot slower than HDD. Also, it will prompt u every time to insert tbe CD. All this hassle can be bypassed by using the staging area. Read the Installation help document on how to create it.
For failure reasons, look in ur installation log file which is created in the default Temp folder usually C:\documents and settings\USERNAME\local settings\temp for WinXP or C:\winnt\documents and settings\USERNAME\local settings\temp for Win2K.
post or email me at [email protected] or [email protected] for further help/details.

Trying to learn pointers and structs, getting stuck (C)

Hello. I've been reading along in the K&R (2nd ed, ofc!) and my aim is to make a simple blackjack clone as my first game. It's supposed to run in the terminal and have simple keystrokes for actions. I'm stuck on building the initial deck and a debug function to test and ensure the deck is built properly. What I have so far is in the following paste:
http://sprunge.us/JUMS?c
Understand that I'm sort of flailing about in my understanding of pointers and how they interact with structs. As far as I can tell, there are two ways to do this; with pointers and with array subscription. I'd prefer the latter if possible since it would be easier to understand, but I'd like to learn both. The problem I'm getting is that my deck isn't being built properly, which makes the test_deck() function return a few bogus cards and then a bunch of zeros (if it doesn't segfault!)
Any help would be great.

struct card nd;
struct card *pnd;
int suits;
pnd = &nd;
pnd++;
nd = *pnd;
Not good. "nd" is *one* instance of the struct, and "pnd" points to that. Incrementing "pnd" points it to a memory location after the end of the 'array' (which is only one element long). This is why it's segfaulting.
Here are two ways to do it, one using pointers and one using array indices (pointers in disguise). Both return a pointer to the deck (as it's an array), so the rest of your code will need to be slightly modified:
struct card* create_deck (void)
struct card* nd = (struct card*) malloc (sizeof (struct card) * 52);
struct card *pnd;
int suits;
pnd = nd;
for (suits = 1; suits <= 4; suits++) {
int n;
for (n = 1; n <= 13; n++) {
switch(suits) {
case 1:
pnd->suit = 'h';
break;
case 2:
pnd->suit = 'd';
break;
case 3:
pnd->suit = 'c';
break;
case 4:
pnd->suit = 's';
break;
pnd->value = n;
pnd++;
return nd;
struct card* create_deck (void)
struct card *nd = (struct card*) malloc (sizeof (struct card) * 52);
int suits, n, i;
i = 0;
for (suits = 1; suits <= 4; suits++) {
for (n = 1; n <= 13; n++) {
switch(suits) {
case 1:
nd[i].suit = 'h';
break;
case 2:
nd[i].suit = 'd';
break;
case 3:
nd[i].suit = 'c';
break;
case 4:
nd[i].suit = 's';
break;
nd[i].value = n;
i++;
return nd;
edit: Of course, you will also need to free the returned value at some point.

Logic keeps losing controller assignments???

I have an Axiom 49 with it's transport buttons assigned to various logic functions. I have assigned these in the key command section by "learn new assignment" Every so often these commands stop working altogether as if Logic "forgets" them. When I look at the learned command line it still shows the assignment but it isn't until I "relearn" the exact same assignment that it works again. This is extremely frustrating. Does anyone know why this happens and if there is a workaround? Thanks.

This may work for your controller assignment issues. I haven't tried that specifically but it definitely works for solving problems with midi ports changing depending on what you have hooked up when you boot Logic.
The CA (Controller Assignments) are "Pre", regarding the Logic Physical Input in Click & Ports layer, so this will not solve the "Input Floating Ports" problem I guess... I think a little tip using IAC bus can work cause once IAC is activated it is a MAC constant virtual port.
*The IAC Tip*
1. Cut the "Sum" cable from the Physical Input and cable the IAC (Bus1) port to the Monitor object (1) - see the pic below. You can name the Monitor (IAC Bus1 IN) etc.
2. Cable all physical ports to the "Sum Physical Ports" Monitor object (2).
3. Create an Instrument object (3), assign its port to IAC, set its midi channel to "All" and cable from "Sum Physical Ports" Monitor object (2).
4. Create a new Fader in the Environment and cable it to the IAC Instrument as shown (4).
5. Move the fader of your external controller you plan to learn to see what is its CC# and channel# in the "Sum Physical Ports" Monitor. (You can skip this step if you are familiar with the physical fader/knob hardware CC assignment previously).
6. Select the virtual fader (4) labeled as "Temp Learn" in the environment and set its output CC definition number and midi channel to match your external controller you plan to learn in the inspector.
7. Save your new midi setup as a Logic template song.
8. Press (Command+K) to open the Logic CA expert dialog. Do the standard "learn" procedure to learn any channel strip or plugin parameter but instead of moving the external controller fader/knob you must move the virtual environment fader labeled as "Temp Learn" (4). This way Logic CA will be learned from the IAC bus (you will see that in the CA expert dialog). After this "Dummy" learn process you can tweak the physical controller - done!
The method must solve the "Input Floating Ports" problem cause all CA assignments will be learned from the IAC port which is constant (non-floating until you may decide to switch it OFF in the Mac AMS).
The other good side is if you decide to move your Logic Preference file ( i.e CA) to another machine - all assignments must work this way ( I did not try yet but in theory it must work ).
Another advantage is that you can patch lots of interesting "Transformer Gears" between the "Sum Physical Ports" Monitor (2) and the Instrument IAC port (3). In other words you can use the Logic Environment as an advanced "MIDI JUNCTION" engine serving its midi processing to other apps, CA etc...

Desperate user need help. My GPIB instrument get stuck with my labview program frequently

Hello to all labview users,
i am a beginner in using labview. I am currently writting a labview program to automatically control a digital control rotator HD201e and a network analyzer 8720a to work with the anechoic chamber. The program receives an initial position, amount of increment and # of steps. My program will then ask the controller to rotate to the initial position and at the meantime, the program will monitor the position of the rotator to ensure the requested position is reached. After that, at the position, the program will ask the NA to perform a reading of the measurement. Once the reading is done, the program will ask the controller to rotate to the next position and does a reading of the measurement and so on.
My program seems to be able to perform the tasks; however, the dig.controller part seems to get stuck around 50% of the time when running the program. Sometimes, even the controller receives the requested position (can be seen from the lcd screen of the controller), the rotator just simply would not rotate; also, sometimes, the controller just simply does not respond when sending the command of moving a position, as in the debug mode (the one with a lightbulb), i see that i got "ok" on all the blocks in the writing portion ofthe program, but the controller just doesnt seem to receive the position (as seen no new position received from the lcd screen) and the cursor on the lcd screen blinks weirdly, due to that problem, my program will then get stuck in an infinite loop.....
Usually, that problem occurs after few positions have been reached.....
so, when that happens, i have to stop my program and re-run it. that means the program will have to re-do the measurement that were read previously....
sometimes i have to stop and re-run my program several times to get all the measurement of all the positions done.....so...that bug renders that program to be an unefficient program.
I have been trying to resolve that bug for weeks...but no success....i have tried to put some wait time between each block....result is not much different...
I have also tried putting "clear" block before and after the "write" block.....same problem.....
I have heard that the serial GPIB "flush" block may help...but i tried..but it seems the controller doesnt recognize/accept flush....
i have also tried using the "Visa open" and "Visa close" block to see if ithat reduces the stucking thing....but seems that the controller can still get stuck....
i have also even tried using "lock asyn" and "unlock asyn" block...but didnt seem to work....
Has anyone experienced such problem.? Is it a known problem with some gpib instrument?
Is there any discrepancy or bugs in my program that i am unaware of that causes this problem?
Any advice and or opinion would be greatly appreciated....
PS: i attached the controller part of my program and the overall program

hi xseadog
i got what you meant about the gpib reference
actually, that final frame works because the gpib reference is already done inside that subvi.
but my problem doesnt arise from that. most of the time ive seen, it arises between the writing frame and the while loop frame. as i mentionned, sometimes. the controller just simply doesnt rotate even i can see the requested position display on the controller lcd screen; also sometimes, just the controller is stuck without acknowledging the write position command. but in labview...while in debug mode. it is shown ok on the block.

Controller assignments lost

Hey, so I just took my midi controller (oxygen49) over to a friend's house to mess around on his computer, and brought it back to my place only to find that the previously learned functions had all been forgotten. It still recognizes it as the same controller, and it says it still has all the settings learned, but none of the knobs or sliders are doing anything.
Oh, but NOW the oxygen49 settings all disappeared, but then reappeared under oxygen25. Which makes no sense, since I don't even have as many controls on the 25. I DON'T KNOW WHAT'S HAPPENING, CAN SOMEBODY PLEASE HELP ME? I REALLY don't want to go through and make it learn everything all over again.

Your controller assignments are stored in the Logic controller preferences, not eh regular preferences where your key commands are.
When Logic crashed, it probably didn't write the preferences out properly.
If you have custom controller assignments, make sure you back up the controller prefs:
/user/Library/Preferences/com.apple.logic.pro.cs

Login gets stuck -- only volume keys get it unstuck

On two of my computers (iMac and Mac Mini -- both recent and both running Lion), the login screen often gets stuck. I click the user to login or start typing a password and the computer just stops responding. The only thing that fixes it is raising and/or lowering the volume (in either order, but it's the volume that does it). Once the volume is changed, the system goes back to normal and the letters I typed appear (or rather dots do -- this is the password field after all). Very occasionally it will get stuck twice during the same login.
This is obviously a huge issue logging in remotely because I can't get the volume keys to work via screen sharing (or at least I don't know how to).
This happened almost immediately upon setting up the systems, so I don't think there's a third party app issue at play.
Has anyone experienced a similar problem?

That is an extremly strange scenario, even for one computer, the fact it's happening on two is bizarre.

Canvas gets stuck

What does it mean when a white circle with a black X in it appears in the upper right part of the Canvas? Whenever that happens, the canvas gets stuck on a single frame and freezes up. Scrubbing the playhead back and forth in the Timeline then does nothing in the canvas; there is no motion there. I usually have to quit Final Cut Express and relaunch it to free up the canvas.
What's the deal there?
Tom

Thanks for the info, Tom. It's FCE 2.0.3, and yes, the canvas is set to "Fit to Window." All these clips have been in the project for a long time, so there's nothing to render.
I sometimes enlarge the Canvas window to see details better, and that seems to be when the Canvas most often gets stuck and freezes (with the X appearing). Do you suppose FCE can't keep up the frame rate in a larger window?
Anyway, if it is processing something, it never seems to get finished doing it. And when it gets stuck, I can't unstick it without quitting and restarting the program. While the canvas is frozen, no matter where I click on the Canvas' scrubber bar, the video in the Canvas won't jump to the new place. I can also run the playhead up and down the Timeline witn no effect on the Canvas. It remains well and truly jammed. Very annoying.

Logic Express 9 doesn't remember my controller assignments

Hi,
I'm using M-Audio Axiom 25 and UC-33e with Logic Express 9. I know how to use the midi learn function, and I'm able to get everything working until I quit logic and open it up again. After that, the previously working assignments won't work, even though logic shows them in the controller assignments window and shows that some midi data is coming in. I've been searching the forum and m-audio forum as well, and they said, that the problem must be with logic. Apparently I'm not the only one with the problem.
However I managed to get the key commands work (with Axiom 25, not UC-33e) by exporting them, but I'd also like to be able to use the knobs etc.

I was never ever able to get Logic 8 to remember my controller assignments for very long or at all. Nor was I was ever able to find a solution to the problem despite all my efforts to try.
My solution was third party. I purchased a Novation Remote SL which uses Automap. As aggravating as it was to have to do this, it solved my problems permanently. Automap is Novation's software that maps itself to Logic as well as to many if not most audio units. It also perfectly controls transport functions without a hitch.
I felt a bit non plused that such a simple feature in Logic was never very reliable. I haven't tried it since upgrading to Logic 9 since I'm still happily using the Remote with Automap. Hopefully someone can provide better help other than simple explaining how to set the learn function up in Logic. The manual explains that just fine. A better explanation as to how to keep it working or get around the bugginess of it would be more useful - and that I was never able to find.

Logic gets stuck in a funny kind of loop when i hit the stop button twice!

Hello,
i bought a Midikeyboard Novation Remote 61.
Working with Logic is just fine except one Problem:
since i got the remote i've a problem whereby if i hit the stop button twice on the remote logic gets stuck in a funny kind of loop at the start of the song
Does anyone else have this problem and how can I get it fixed?

Only thing that I can think of is that it is triggering some sort of repeat trigger (I had this with my ProjectMix) on a command. Check and see where your stop button is mapped to in the controller assignments (in your prefs) and see if it is mapped as a key command with a key repeat. That's all I can think of for a start.

Running a mid 2009 iMac on 10.7.5, 3 gb memory, 320 gb hd.
Suddenly the computer stoped reading DVDs and the only time I can read a CD is if I restart. Quite often when I insert a CD it gets stuck and I cannot get it out until I restart and it shows up on the desktop where I can then eject it.
I have checked and double checked the finder prefs and all looks normal showing a check mark on CDs,DVDs etc. (the ones I want to show up on the desktop)
I have reset the PEAM, repaired permissions with both the disk utility on the computer and the disk utility when I start up in the Recovery Disk. I did notice that sometimes the permission repeat the same correction several times before it moves on, and sometimes it doesn’t. I have Windows installed on a partition but I keep it unmounted until it is needed for my wife’s work. The dock seems to be just fine and all the apps seems to run just fine. When I insert a photo CD iPhoto does not open but when I insert a music CD iTunes does open.
Also, most every time I open iPhoto it takes a long time(sometimes as long as 2 minutes) for it to load.
Sometimes my Mail (Mail 5.3) does not post new mail but most of the time it does.
Once and a while it seems like the computer slows way down but then it seems ok ten minutes later.
All of these ‘things’ seemed to have happen suddenly and I have not downloaded anything from the internet in some time.
Of course the warranty and extended warranty are both no longer in effect having had this computer for more than three years.
I am running Java and Adobe Player because some of the sites I go to a lot require both.

I believe that insufficient RAM may be the source of some of your problems. If you have a RAM of somewhere 4 to 8GB, you will experience smoother computing. 3GB doesn't seem right, so you might want to learn more by going to this site:
http://www.crucial.com/store/drammemory.aspx
I don't know what know what's happening with your optical drive, but it seems you use your drive quite a bit. In that case, look into a lens cleaner for your machine. It's inexpensive, works quite well.
I hope you'll post here with your results!

Why doesn't Logic Pro X remember controller assignments when I switch patches?

I'm trying to work with setting up External Controller Assignments with my Akai MPK25. I'd like to have Knob 1 map to the 1st Automatic Smart Control knob I can see (like Timbre or Cutoff or whichever is leftmost) OR have Knob 1 always map to the same paramater (Timbre, Cutoff, etc).
I'm able to successfully set them up on a single patch but the moment I switch to a different patch, Logic completely forgets the assignments. And if then I switch back to the original patch, the assignments are also ost. If I toggle "Compare" in the Automatic Smart Controls window back and forth, Logic loses the assignments. But oddly, it remembers one or two (out of eight potential paramater assignments).
How do I get Logic to remember these assignments?
Here's a screenshot of my window: https://www.dropbox.com/s/uqzqen6etkh0uxf/Screen%20Shot%202013-11-24%20at%205.02 .43%20PM.png
Thanks so much in advance.

No, no need to chase any pur.
You can clickhold that No Output slot and assign an output.
...but for that to work you need to have chosen your audio hardware in the preferences, of course. And while you're at it, make sure you also have all Advanced Tools enabled.

Learned controller assignments often get stuck in Logic.... (?)
