MIDI Stopping problem in LE 7.01

Hello,
I have two LE setups, one on an iMac G5 and one on a PowerMac G5, both using M-Audio 2x2 interfaces. Both systems experience a problem in Logic where the MIDI output ceases after 5-15 minutes of continuous playback. The problem is resolved by stopping playback and then starting again. I don't need to quit or turn off any hardware. Our problem is that we are using these systems for research purposes, and having MIDI cutout on us invalidates a given testing session. We would like to be able to solve this and continue using LE, but are considering switching sequencers unless we can resolve this. Any ideas?
Thanks,

Are you using MIDI to trigger internal software instruments on your Macs, or external hardware sound generators? Have you tried saving the file as a Standard Midi File in Logic Express, then using something like Quicktime Player to play it with simple internal sounds? You may also have extraneous Midi controller messages that could cause the problem. Open the file in Logic Express, open the Event Editor, and try the various filters to find anything bizarre other than notes in your file.
Then too, it could just be something about your M-Audio interfaces. I have an old MOTU Timepiece interface and have played continuous looped sequences for hours in Logic Express without problems.
Let us know if you find the problem!

I need to upgrade my 10.5.1 os on my G4/1.25 (I'm having some audio-midi setup problems), but it's a machine that is not connected to the internet. Do I have any options? Thanks!

Friends,
I'm having some audio-midi setup problems on my G4/1.25/10.5.1 machine. I'm thinking that a routine OS upgrade might help. However, this machine is not connected to the internet. Are there any alternate methods for upgrading system software? Thanks in advance!

OK, what you should do is download the updates on another machine and burn them to a disc. Start at this link http://support.apple.com/downloads/#leopard for downloads and find, among other things, the 10.5.8 combo updater that works on PPC machines, plus security, QuickTime and other updates. Going from 10.5.1 to 10.5.8, there will probably be a bunch of things that you should install. Being off the internet with the machine, you can't have Software Update sort it out, so something might get missed, unfortunately.
My suggestion is this: if it looks like you might need a download, get it onto that disc.

Thank You,
Muhammad NasirSo bassicly you are saying this is a problem of the emulator? Which hasn't anything to do with ADF Mobile or Oracle.
Googling your problem doesn't seem very hard.

Zen MX Skip/Stop Problems

I just bought a 'like new" Zen MX from amazon.com and today was the first day I've used it; every four or fi've songs it will skip/stop for a split second every couple seconds and then play like normal. My question to anyone who can answer this is: does this mean it's gonna die on me pretty soon or is this just an annoying but normal bug? Because I am obviously not covered by Creative Labs since I bought this from an amazon merchant so if this mp3 player is going to die in three months I really doubt that I could get my money back from the merchant after that long. Any help would be appreciated!

Hi,
You might want to perform a Clean Up, Reboot to see if it resolves the Skip/Stop problem.
To enter recovery mode:
<li style="padding: 0px; margin: 0px;">Turn off your player.<
<li style="padding: 0px; margin: 0px;">Press and hold the power button to turn on the player.<
<li style="padding: 0px; margin: 0px;">When the Creative logo appears , press and hold the back button until the Recovery Mode screen appears. Three menu items are shown:<strong style="font-style: normal; font-weight: bold;">Clean Up[/b], <strong style="font-style: normal; font-weight: bold;">Format All[/b], and <strong style="font-style: normal; font-weight: bold;">Reboot[/b].<
As for the cancer warning, I suppose you already have your answer after reading these threads.

Macbook pro mid 2011 problem to eject usb hd

Hi, using a macbook pro 13 mid 2011 with w7 professional 64bit
I've a problem almost every time I connect an external hd to the usb
and then i try to eject it using the icon on toolbar... the hd usb is seen
like external keyboard... So if I eject it the macbook pro crashes...
the internal keyboard stop working. Any one has a solution ?
It's a very annoying problem.
Thank Yoy.
F.C.

This sounds like a Windows configuration issue. Have you tried using the device manager to "remove device" on the HD while it's attached? THis should remove the drivers, etc, then allow you to re-connect it and let the OS re-detect and load drivers. I would think that this would allow the OS to select the right driver for the external HD this time instead of the HID driver...

Discontinuous midi playing problem

Recently I am developing a game on Motorola V980. A sound playing problem has occurred in my working progress. That is when I continuously play two Midis, first one worked fine, but second one was played discontinuously. However, when I played the second MIDI independently, such problem did not occur.
Detail logic of my program were organized like this:
1) Open a binary file and stream it
2) Copy streams into local buffer, such as byte arrays
3) Create Player object for each sound and organize them in an array
4) Invoke Start, Stop, ... methods according to my game logic
5) Finally, a level was completed, stop and destroy Player objects and recycle memory allocated.
I am wondering if it is a bug of sound system of Motorola V980. So I looked for solution in relative Motorola official specifications, media guides and many J2ME developer forums. Unfortunitely nothing I have got. Anyone kindly give me some advices on this issue would be greately appreciated.

Novice Logic Express user has Midi setup problems

Hi, folks. I'm a novice Logic Express 7 user (I used a much earlier version as a sequencing package a very long time ago). I've just installed Logic Express 7 on my Mac OS X and connected my Technics PCM Digital Piano PX 107 to the Mac via a MIDIsport UNO midi interface. There's some stuff happening (and not happening) that I don't understand yet.
Firstly, I can see on the transport window that midi in and out are both registering events, but I am getting a wierd echo of very low notes coming back through the keyboard speakers, making it impossible to make any sense of what I am playing.
Secondly, if I turn the volume off on the digital piano, I can't hear anything at all, even when midi events are being registered.
Thirdly, I don't appear to be able to record anything. Once I click record, the midi seems to stop functioning altogether.
Lastly, my midi metronome click comes back through my keyboard speakers as a very low note.
Should I have my keyboard volume turned up at all? (My guess is I shouldn't, but I can't hear anything at all at the moment if I turn it down). And can anyone help me with these perplexing problems. All contributions very gratefully received, thanks.
Mac OS X Mac OS X (10.4.5)

I think you need to figure out how to turn off local playback on your keyboard. You are probably hearing the sound from your keyboard as you are playing, plus the sound that the keyboard plays when Logic is sending midi notes.
There appears to be another problem that your midi is being transposed down in Logic. That would explain the low "echo" and low metronome click.
All the sounds are being made by your keyboard--that's why you can't hear anything when you turn it down. What is it that you are trying to do? Do you want to record midi and have that play back through your keyboard, or do you want to just use your keyboard as a controller for Logic's sounds?

Mac Mini Server mid 2010 problems

I have a Mac Mini server mid 2010 model, running Mountain Lion server.
It reported a fault with the HDD in the lower drive bay some months ago, so I changed the disk. It still reports a fault with a new disk and the original disk works perfectly in a portable enclosure, so it cannot be a disk problem but something more serious.
I have now discovered that bank 1 ram slot has failed. I have two 2GB ram modules, and whichever way I insert them bank 1 claims to have no ram.
Are these two problems related, and what is the fix. I'm just hoping there is something simple and that I don't need to replace the logic board.

Run Apple Hardware Test to try and pin down where issue is.
However, it does sound like it is a logic board issue. These
days, since pretty much all the ICs on the board are BGA
(ball grid array), even the best electronics hobbyist can't
replace them.
I just did a quick Google of logic boards for 2010 Mini and
they are pretty pricey ($500-$600 range). If you have Applecare,
however, you should be covered.
At that price for logic boards, you may be better off looking for
someone selling a 2010 Mini and just replace yours.

ES2 midi assignment problem

Hey,
yesterday I made midi assignments with my ES2 without any problems.
Then I chose a preset of the ES2 - no assignments possible and now even with the standard preset no assignments are possible anymore.
Did anybody had problems like that?
Please help

*I've got so much to learn about MIDI.*
Well, MIDI (as a protocol) is quite straightforward (except maybe the 'sysex' department - that can be a science of its' own). It is its' signal flow that can be bewildering sometimes... as in this case...
10 is the customary channel for drums, but there is no reason other than common practice. Drums will work on any channel. I often have a barebonesrythmsectionpopband to start a song: Piano on ch 1, Bas on 2, and guitar, or synth on 3 and drums on 10. But I could put them on any of the others as well (except 16, which is often used as the default sysex channel).

Audio MIDI latency problem (from iOS 7.0.6 till current version)

This problem started since i updated my iPhone 5 16GB and iPad Air 32GB Wi-Fi from iOS 7.0.4 to 7.0.6 (iOS 7.1 still have this problem):
i'm a DJ and using my iPhone and iPad as mobile but powerfull dj setup (with installed DJ Player ios app (http://djplayerapp.com)) and connected Vestax VCI-400 dj controller (with separate power adapter and powered hi-speed usb cable) via original Camera Connection Kit.
MIDI touch responce was perfect until upgrading to iOS 7.0.6. After that i got audio latency issues.
For example: i press to any button or moving crossfader and jog wheels for scratching on dj controller but sound starts just after a few seconds. DJ controller works fine (with usual aftertouch audio responce) with other music apps instead this one.
By the way: Connected AKAI MPK25 midi keyboard responce is OK in DJ Player and in other apps too (with separate power adapter and connected CCK via USB hub) without any problems after iOS updating on both Apple devices.
Main topic was started a month ago on the forum of DJ Player app developer: https://getsatisfaction.com/djplayer/topics/sound_delays_when_playing_from_vesta x_vci_400
Anyone have the same problems?

Java MIDI Synthesis Problems!

Hi! I've been searching for a solution to my problem for almost a week now. I'm new to Java so I was hoping someone here could help me out!
I'm familiar with a few other programming languages and I got all the "Hello World" stuff going, but the MIDI synthesis in Java is stumping me. Maybe it's just my computer that's the problem, but I'm not sure.
I'm using Eclipse for programming.
Inside my miditest.java file I have a miditest class with this code in it...
import javax.sound.midi.*;
class miditest
        public static void main(String[] args) {
               MidiDevice.Info[] mdi = MidiSystem.getMidiDeviceInfo();
               Synthesizer synth = MidiSystem.getSynthesizer();
                  synth.open();
               final MidiChannel[] mc = synth.getChannels();
               Instrument[] instr = synth.getDefaultSoundbank().getInstruments();
               synth.loadInstrument(instr[90]);
               mc[5].noteOn(60,600);
               synth.close();
}At "MidiSystem.getSynthesizer()" it's throwing "MidiUnavailableException". It's throwing that at "synth.open()" too.
I've checked my MIDI for availability... and I'm assuming since every other program can run MIDI that my device is working fine.
Anyway, thanks for any help!

You are going to have to tell us exactly what type of installation problems you are having w/Java? Any error messages? What do they say? Where did you download Java from? Which browser & version are you using?
I also play games on Pogo, recently updated Java and so far no problems playing their games. Although I do have different OS'es than you. I use both SL (MBP) & ML (iMac).
I did have to repair permissions and restart my computer a few times for the Java to "take" as I had to do several Java installations & one applet installation.

Iphoto '11 book upload stops problem

I had the frustrating problem of iphoto '11 stopping during uploading of photo books and found a simple solution. I left the process running overnight or during mornings and for 5 to 6 consecutive the process stopped midway and I found an error message. Tried restarting the whole thing, rebooting, turning off everything else that was running, etc. Same result.
I tried this and it has worked so far for 3 books in a row in the first try: I went into the System Preferences and extended the computer sleep time to "Never" and left the process running.

Non stop problems since update

Ok, so I updated to 10.4.8 and am now on 10.4.9 as of yesterday. Anyway, upon updating to 8 and deleting my windows partition with bootcamp, I have been having more issues than ever befor.
First my internet started disconnecting constantly which seems to be ok now, but Ichat constantly stops working.
Then my macbook started running a lot hotter.
Upon working on a project in photoshop (I was saving 150mb images, a lot of them) my computer got unbelievably hot. Now the bottom is kinda warped, the left corner is lifting, just to the right of the screen opening button the case is lifting, above the card slot is slightly buldging out, and now if i pick up my laptop by the left side where the speaker is, the screen shorts out and will only come on by restarting.
Then the battery is doing this strange thing where it will say it is at 4700 for full charge capacity, then 15 minutes it will say 3200, and will go back in forth between them. Then when it gets down to 0% it will run another 20 - 40 minutes. I have recent the PRAM and done all the suggested resets and what not.
Seriously, this is rediculous. It's about 9 months old and is the intel core duo 2.0 ghz 15 inch.
Any ideas of what mac will say about this if I bring it in. I'm a student and can't really afford to be having so many problems with this.

MIDI PORT PROBLEMS HELP!

This is a recent problem. In environment when clicking to change port to either RAX on my desktop, V-Stack, and/ or Plogue Bidule, the first 3 ports work fine but anything past port 4, whether that be Bidule 4, Rax 4, etc etc, just clicks to "All" and thereafter reverts to the first bunch of ports on the list as opposed to the final ports on the list.
I have trashed prefs but this hasn't helped, and yes, it happens on all Logic songs, whether new projects, or legacy projects from a while back.
I'm running a 2 x 3GHz Quad-Core Intel Xeon with 16GB Ram. Logic Vers 8.0.2, RME Fireface and Midi Over LAN.
Thanks in advance for your help chaps and chapesses.
