Quicktime 7 and Audio MIDI bugs in 10.3.9

I posted this in the 10.3 audio forum and am trying here as well
I am having overloaded CPU issues that won't allow playback in Pro Tools 6.8 M-Powered and made Reaktor 5 unusable. Reason Adapted cannot access core MIDI. This issue has grown worse as the day has gone by. I have been trying to trace down what the problem is and from what I can see, Quicktime 7 (.0.1 -.0.2 - .0.3) has caused major audio bugs in 10.3.9 OS. The first problems I had was when I first installed QT7. So here is a list of symptoms.
I can't open MIDI set up in the Audio MIDI set up.
I get popping and high pitch oscillation in Pro Tools and Reaktor.
The oscillation is also audible from inside the computer (Yes, I know this is the CPU making the noise)
I cannot get playback in Pro Tools because of CPU overload or buffer size is to small (I have the buffer maxed)
I cannot use and external MIDI instruments due to crash of the set up
Digidesign (Pro Tools) just posted issue very similar to mine last week.
Native Instruments (Reaktor) tech support says there is an issue with g4 Power Books and the CPU but they aren't sure what is causing it.
Just a side note, On my G4 Desktop, All is well with QT6.5 and 10.3.9
On my G5 desktop All is well with QT 7.0 and 10.4.1
I am using G4 (Ti) Power Book that is almost 3 years old
512 RAM
1GZ CPU
a M-Audio Firewire 1814
a Lacie D2 160GB in the firewire800 port
I really think this is a Quicktime bug. If any one has figured out anything or wants to dig into this further....... I wish there was an un-installer for QT7.0.3 so I could go back to 6.5.2 and all would be fine. Below is the crash report of the Audio MIDI set up

Thank you Kirk for your reply and the solution. I couldn't find the .smil format option under Sys Prefs/QuickTime/Advanced MIME Settings, but then I realized I didn't install Real Player after the OS X upgrade from 10.3.9 to 10.4.7. I installed Real Player and restarted the system. The speech file that was not working came alive with the Real Player icon intact.
I really appreciate your help and I look forward to reading your book on QuickTime in the near future.
Sincerely,

Sample rate and audio-MIDI sync issues

Disclaimer: I did read other posts similar to this but couldn't find an answer to my specific situation. So here it is:
Logic was perfectly fine when everything was running at 44.1kHz sample rate. Then I got vocals at 48 kHz so I had to convert the sample rate in Logic Pro to match it.
Suddenly I get a slew of "Error trying to sync MIDI and audio" messages. After crying and changing the sample rate back to 44.1, then to 48, and over and over again, it finally works again.
So Logic is fine at 48kHz. But when I go to a track that's at 44.1kHz, I get the sync messages again and have to play "toggle the sample rate" for about 5-15 minutes before Logic decides whose master again.
Why is it doing this? Do I need to change Logic Pro to some kind of default settings every time I go from one song to another with a different sample rate? Or will this not be an issue if I upgrade to 7.2? (I have 7.1.0)
PowerPC G5 Mac OS X (10.4.6)

This is not a bug, but a nuisance.
You should upgrade to LP 7.1.1, which is way more stable than 7.1.0. No need for you to go to LP 7.2.
"Then I got vocals at 48 kHz so I had to convert the sample rate in Logic Pro to match it."
Are you certain, that in your song, in your regions, you used the newly converted 44.1kHz files, chosen from the Audio Window, and not (still) the old 48kHz files?
"So Logic is fine at 48kHz. But when I go to a track that's at 44.1kHz, I get the sync messages again"
LP doesn't do this well. And for a reason, but we'll not get into this now.
See: "Audio > Sample Rate > ..." and select one.
Perform proper conversion and make sure ALL of your audio files running in your song are congruent. Check your Audio Window and the files associated to the regions.
Set up your autoload to contain these settings. From then on, whenever you know that you will be importing other sample rates, change the settings in "Audio > Sample Rate > ..." before loading the sounds/files, if indeed you are starting from scratch. This will save you significant time.
Been there, done that.

ITunes and Audio Midi settings for digital output sampling frequency

Most of my music is sampled at the CD standard of 44.1 kHz, but some is 48 kHz.
I have Audio Midi set to output 48 kHz with 24-bit depth.
I've been told that to avoid having iTunes up-sample when playing 44.1 kHz music, that I need to quit iTunes, manually reset the setting in Audio Midi to the lower, matching, number, and then re-start iTunes.
This strikes me as odd. Is it true? If so, is there any less cumbersome way to deal with this?

Wheat I agree entirely with your last sentiments.
I had a similar problem to 'Luckydog'.
I have a Roland HP3 digital piano which itself is a standalone musical instrument (synthesiser if you like) but also has midi in/out and audio in/out.
I made the mistake of connecting my Mac PBG4/GB2 setup to my HP3 via the Edirol UM2 USB interface, expecting to hear my piano's sounds recorded in GB2. Of course GB2 did not record anything when I selected real instrument track beacuse the Roland, I think, was sending audio not midi data to GB2. What I have since realised is that to record a real instrument whether it be a digital piano (or acoustic piano via microphone) is to set the GB2 input to audio and feed the signal from the Roland via its audio outputs to my Mac via audio interface. (I have a USB Grifin iMic).
Of course I could use the Roland purely as a midi controler and select a software instrument track in GB2, but I also have a Radium 49 simple midi controller keyboard for that.
One thing that does puzzle me though is, that if I hook up my Roland via the UM2 to a WindowsXP laptop running an app. called Cakewalk Music Creator, the Roland sounds are recorded in the timeline and can be viewed, edited and printed as conventional music scores(great for composers!!) Also the Roland track recorded in CMC can be played back through the Roland's on-board sound generator.
In this scenario there is no audio feed between the Roland and the PC only two way midi via the UM2 USB/midi interface.
This is seems to be a fundamental difference between GB2 and the Cakewalk product. Can you explain what's going on hear Wheat?.
Sorrry such a long post !!

Can Anyone suggest and audio/midi interface for MacBook Logic Express?

Can anyone suggest an audio/midi interface for use with a MacBook and Logic Express? I'm seeing a lot of problems with Tascam devices; does anyone have an interface that actually works well? Two audio inputs and midi i/o would suit my current needs, but more would be fine if it works.
Thanks!

Any of the Pro-Tool Mboxs will work with Logic Express. Kind of an unadvertised feature. But I have an original M-box with very nice Focusrite Preamps that works like a charm. No midi though.. some of the newer M-boxes have them.
Also, I have a Presonus Firebox and I know they make some smaller interfaces. No problems working with those.
M-audio Makes some great interfaces too. Their Fast Track pro would probably have everything you need for under $200.

Streaming, Flash, Quicktime, and Audio Drivers not working

Purchased and installed 10.5 on Saturday, installation caused a crash and finally got it to work today, but now when trying to view flash and quicktime streams on safari, I just get a question mark. i've read all the other posts on this, tried changing the MIME settings, no change.... those posts were not helpful.
PLUS: the install deleted the audio driver, i can't adjust the volume, nothing comes out of the speakers when itunes is play a song. is there any way i can restore the drivers for both these problems without re-installing 10.5 and risking another crash?

Try this for the flash/quicktime problem:
Go to home/library/preferences
Find the file named com.apple.quicktime.plugin.preferences.plist
Move the file to your desktop.
Quit Safari, then restart Safari. Problem fixed? If so you can trash the plist file from your desktop.
On the audio problem, I'm not sure. Perhaps check the settings in AudioMidi Setup in your Utilities folder.
Hope this helps,
Jeff

IPhoto slideshow to quicktime and audio tracks fadeout, undesirable.

I made a quicktime movie out of an iPhoto slideshow and the audio tracks fade out. Can this be prevented?

You probably will need a 3rd party application to convert the . mov QT file that iPhoto creates into a format for the iPod. Some are VisualHub, ViddyUp, and iSquint. You can find them at VersionTracker.com.
Happy Holidays
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Quicktime and Audio inputs.

Hi everyone,
thanks for your time.
I need to record some fast videos with my macbook pro and I want to use Quicktime because it is really fast and easy to use.
This is the problem.
When I start to record a new video and I select my "Focusrite Pro 24DSP" as main audio interface, Quicktime records only inputs 1 - 2.
How can I choose other inputs, like 15 - 16 (where it is the loopback function), or simply record the Mix Out?
I need to record my keyboard along with some songs on iTunes.
I tried to go into the audio preference, but I can't do anything for the inputs. I am asking if with another audio interface, like an Apogee duet maybe, I can resolve this problem (I can select which channel to record! 1, 2, 3, 4... or the DAW, or MIX L - R).
I could do this with my windows XP and with a 30$ USB interface (I could select the mix as record input from the audio preferences).
Why can't I do it with a 1500$ Macbook?
I don't want to use Logic Pro for this (it works good): I need a fast video - audio record, but I just have to record the complete mix (L - R), not only 1 - 2 inputs.
I hope that everything is clear!
Thanks for your help,
Marco

I just did my first feed Monday night. I used a video mixer and Mackie board myself. I feed the audio and video(component) into my DSR-20 VCR, which I also use for a tape backup recording. This then feeds the QT Broadcaster. I don't think you can feed anything but a firewire machine or iPhoto camera into Broadcaster. Might work with an USB camera/vcr???
I feed H.264 video, at 320x240 with mono 16 bit audio. Hint... don't do disolves, as they increase the frame rate. simple cuts-only seems to be the best. We also fed keynote slideshow into switcher... carefull there, as it produces saturated colors that will effect the signal... the switcher will think the super saturated video is sync and glitch the video. red is the worst, of course. Next week I am going to use a little proc amp to drop the chroma a bit.

Spectrasonics - White Noise, No Audio, and Audio/Midi Sync Sample issues

Just installed all of the spectrasonics software. Omnisphere, Trilogy, RMX, Atmosphere. Im getting very mixed results.
The patch plays, sometimes there's clicks. Then it goes to white noise. Then there's no output.
Thoughts? Thanks

I hear your point re Spectrasonics. Generally when you call a software specific provider, they tell you that they do not provide support for 3rd party software - e.g. Logic etc. Im not sure the troubleshooting is on the Spectrasonics side. Actually, all of them have worked succesfully at various points. Further, the white noise now comes and goes with EXS 24, Battery and others. So, it does not appear to be a problem that is specific only to Spectrasonics.
I use an Apogee Duet. I have tried different buffer settings (256 and 512) and that seems to help with certain apps. E.g. Kontakt appears to work better with less latency at 256. Spectrasonics, when it works appears to work better on 512.
Thanks

Loss of audio after upgrade os x 10.7.5, reset PRAM, SMS, updated software and other recommendations i could find. Master volume sliders inactive in Audio Midi section. Can see sound bar responding it input on line in but is not being internally routed.

Recently upgrade to OS x 10.7.5 resulted in loss of what appears to be internal communication of line in audio, and output. Have tired several remedies including resetting PRAM, SMS, updating all software, multiple Sound and Audio Midi applications adjustments to no avail. Also no audio is recognized on USB mixing board I tried as well, though Audio USB Codec was displayed. THe master volume sliders and other options are greyed out on Audio Midi application whn I try to troubleshoot that. Nothing external will play through computer speakers, but internal sounds and iTunes play normally.I made sure the audio sampling rates were default. Software issue or soundcard/hardware failure.?..Pullin my hair out!

Might be corrupted sound preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following;
/Library/Preferences/Audio
Click Go then move both .plist files from the Audio folder to the Trash.
com.apple.audioDeviceSettings.pllist
com.apple.audio.SystemSettings.plist
Restart your Mac. See if that made a difference ...

Yamaha MO8 and Korg Volcas with Logic Pro X- recommendations for mixer and audio interface

I plan to use Logic Pro X to access and configure the patch list for my Yamaha MO8 workstation. The Steinberg software I downloaded previously didn't work and never allowed me to configure the sounds. From what I've heard, I was told to use a cheap mixer or a Audio/MIDI interface (like the Scarlett 2i2 or 4i4). The Yamaha MO8 will be used as a master and has MIDI IN, OUT, and THRU. I also have the Korg Volca synths to use as slaves (they only have the MIDI IN port), and plan to connect them to the MIDI THRU on the keyboard. I already have the Yamaha USB driver installed, and the Mac recognizes the device. I also have the Portmidi app and wonder if that will allow me to see the patch list (with the actual names, not numbers).
What mixer and audio/MIDI interface do you recommend to use the Yamaha MO8 and the Korg Volcas? Just to be clear, I don't want to use software synths, but would like to use the external instruments to get the audio (which I know can be selected through the Environment Panel on Logic Pro X).

Anything with 2 audio inputs and 2 MIDI outs.
-Out HP jack of Volca-1/8 to 1/4 adapter into Audio interface 1 (For any that are stereo use both 1 and 2 and use a Y splitter in addition to 1/8 to 1/4 adapters.
-Midi out from interface to Midi in of volca (Or buy a USB to MIDI interface for about $35)
-When starting up the volcas hold down the "Memory button" the LED will tell you what MIDI channel it is set to, you can change it if you wish)
-Create external MIDI track and set it to the same channel as the Volca (Only if you want to do sequencing in the DAW, if thee Volca sequencer is handling it then not necessary)
-Patch together the Volcas via the "synch out/Synch in" jacks to insure they are synched
-Record them all together or one at a time, depending on how many simultaneous tracks your interface can handle.

Audio Midi Setup, multichannel speakers, Snow Leopard & possible bug

I scoured this forum as well as the usual places across the net and haven't seen any mention of this issue, thought I'd post it here and see if anyone else has had this issue. I'm having a problem with a fresh install of 10.6.2 that I detailed in a bug report to Apple. Here's what I sent them:
"I have a firewire audio interface I use successfully with Logic Pro/Quicktime Pro 7/Finder in a multichannel (5.1) configuration for scoring and post, which works fine in 10.5.8. I can play multichannel (interleaved) 5.1 files bounced out of Logic Pro in Quicktime Pro and from within the Finder using QuickLook, and all channels play out of the speakers (which is of course configured properly in both Audio Midi Setup and Logic Pro).
In the latest version of Snow Leopard however, even though multichannel audio works fine in Logic Pro (probably because it has its own multichannel speaker config in Logic's audio preferences), this same hardware setup does not work outside of Logic. Multichannel audio files only play out of the left & right channels (C/LFE/Ls/Rs are summed). I believe the problem is Audio Midi Setup. Even though I enable the correct stream and choose the correct speakers from with "speaker configuration," and even though the test tone buttons work over the appropriate speakers in that window, after I hit "apply," when playing multichannel audio files in QT7 or via Quicklook in the Finder, the problem persists (summing all channels to L & R speakers).
Furthermore, when I click "Done" in the speaker config window and quit Audio Midi Setup and re-open it, the speaker configuration window reveals that my multichannel setup has reverted to Audio Midi Setup's intial state: a 2 channel (stereo) setup. I've done this at least ten times, as well as having deleted the AMS prefs and launched the utility in 32-bit mode with no success."
Has anyone else with a multi-speaker setup had any problems with AMS initializing their speaker configuration, and just plain not working?

I don't know if this will help you, but I once had a problem with Audio Midi Setup forgetting its settings - I found that the settings were only securely stored if I made the changes while logged on as an administrator.

What has happened to audio/midi support in the Quicktime plugin?

I have a six-month old iMac running Mavericks (10.9.3) with Safari 7.0.4. I use midi a lot when I'm trying to learn a new piece of music, which is often. I don't want to have to download a midi file into another app just to audition the file.
Why has the support for audio/midi been removed? (again)
What can I do about it without spending money? (again)
I seem to be in a cycle where over a period of years, additional software is needed for some time and then the feature reappears with an update to either the system or Safari, only to again be deleted. Is it just me?
The outrageous thing is the cost of the Quicktime Pro which in Australia costs AU$37.99 which is more than the cost of the entire Mavericks or Mountain Lion operating systems. I'm sure I've bought this before, but junked it because the feature reappeared, and now it's gone again. I don't want to have to buy it again, particularly not at this price.

Apple has ended support for MIDI in browser playback but they can still be played with QuickTime Player 7 once you download the file to your machine.
QuickTime Player 7 for Mac OS X v10.6.3 or later
The free version is all you need and MIDI files are tiny and quick to download.

Alignment of external MIDI events and audio

Hi,
I've been doing some careful measurements of the timing of MIDI events under Logic 8.0.2. I record a lot of external MIDI hardware, so the timing of external MIDI events and its relation to recorded audio is very important to me.
My setup is OS X 10.5.5, Logic 8.0.2., all relevant patches and updates. I'm using an RME fireface 800 as both the audio and MIDI interface in these examples.
I've created a project in which there is no plug-in of any kind: neither instrument nor effect. Even the klopgeist is gone.
My preferences settings:
Audio/Devices:
buffer=1024 samples
sw monitoring=off
indep mon level=off
I/O safety buffer=off
Audio/General:
PDC=Off (I also measured with PDC=all, to verify that it has no effect)
low latency mode=off
I create an external MIDI track of quantized whole notes: C3, playing on the first tick of each bar. BPM is 120.
I then create another external MIDI track, cable MIDI OUT to MIDI IN on the Fireface, and record the first MIDI track onto the second (i.e., loopback test). The note data is right on the money; within one tick of the original values. I set PDC to all, repeat the test, same result.
I then cable MIDI out on the Fireface to a hardware synth, and call up a patch with a sharp attack. I route the audio output of the synth to an audio input of the Fireface. I create an audio track with this input selected, and record the output of the synth. The recorded audio is early by 20ms or so -- roughly equivalent to the buffer size.
I repeat the test with PDC set to All, same result. PDC has no effect, as you would expect, as there are no plug-ins in this project.
I then set Preferences/MIDI/Sync/All MIDI Output delay to 21ms. I repeat the audio recording test, and now the recorded events are on the money.
Here are my questions. First, am I doing something wrong, or does Logic have a fundamental bug concerning the linkage between MIDI timing and audio timing?
It seems clear to me that this timing error has nothing to do with PDC. There is no "P". Right?
I thought that the RME has timestamped MIDI. The RME manual speaks of very accurate MIDI timing, and I can verify that the MIDI jitter of the Fireface is indeed low, in the 1ms neighborhood. This is borne out by the MIDI loopback test I did above. But MIDI timestamps don't mean anything if they are not correlated to the time code of the audio, haha! What am I missing here?
If timestamping the MIDI data can't work for some reason, could this problem not be solved by having Logic automatically delay the transmission of external MIDI data by an amount equal to the audio buffer size? Put differently, my solution to this problem is to set a MIDI output delay in preferences equal to the audio buffer size, i.e., 21.3ms. And this seems to work. Is that a proper solution, and if so, why does Logic not do such a thing automatically?
Thanks,
-Luddy

OK, so I just retested and here is the best part... I recorded a loop from my drum machine, cut the first note nicely to the 1 on the first bar... using a count in etc.
I played it back and looped outs 3-4 back into 1-2 on my Ensemble. I also played back the same kick on my drum machine just to check this reverse latency issue. I was not concerned with hit for hit layering accuracy. What I got back astounds me!
The "loopback" recording was spot on to the original being played out... totally locked. BUT, the one that was midi clocked by Logic and play from my drum machine came in ahead of the 1??? How is this possible when I am hearing it when monitoring this recording and it is slightly behind? RIDICULOUS! What does this mean?
Logic is NOT recording what I am hearing, but rather recording some timewarped version of it in which it places events ahead of when they happened, but ONLY on midi clocked or midi sent notes!
I have lurked here a long time and I know that there is not much known here about this issue, so before anyone tells me the typical solution I will say as I did in my last post:
I have done a ton of tests like this, I also followed the loopback testing as described on Logicprohelp.com.
Yes I tried it with all PDC modes, SW monitoring on AND off.
I am truly beginning to think that this is a major bug of some sort.
Anyone else out there with hardware that reports latency to Logic (RME, Metric Halo, and Apogee stuff are ones I know that do this) experiencing this abberation?
thanks

Midi and Audio tracks simultaneously armed for recording

All, whilst engaged in laying down the bass track for the guitar solo section of my latest monster his, I encountered one of those sorts of frustrations that makes one long for some means of swift egress from this mortal coil, this vale of tears: that is, while laying down my totally awesome bass track that when they hear it will send JP Jones and Boosty Collins to employee as actuaries, I kept getting the hateful "unable to synchronize the audio and midi error." I'll spare you the catalog of the various lame attempts I understood to remedy this problem, as well as the curses directed toward my fate, and Daw ineptitude in general. Then I nnoticed that both the software instrument tracks (Addictive drums) and the audio track (aforementioned bass) were both armed for recording, signified by the red R in the track header! Well, upon de-arming the software instrument track I was able to record by bass line in a mimimum of takes, and as visions of illegal intozicants and comen of questionable morals dance through my noggin as recompsense for my trouble, with to make the point to all relative newbies such as myself that the answer to problems that seem on surface intractable as usually staring you right in the glazed eyeball.

What?...
I'm sorry maybe I don't understand everything you are sayng... but I can replay to the titles of the Topic!
Actually recording a MIDI instrument and an Audio Track symultaneously comes with serious bug!!!
you cannot use Punch-in on Fly when an Audio and instrument track is armed at the same time...
or better you can but the MIDI and audio output will be dropped for a moment
Provide a Logic feedback
http://www.apple.com/feedback/logicpro.html!
THIS IS A LOGIC 8 BUG!!! BIGGEST SERIOUS BUG!
I suggest you to use Logic 7 when you need that!
Thank you so much for remember me this..
I'm sorry no alternative solution... or.. if you have 2 Macs you can use one for Logic MIDI and another one for Logic Audio!

Midi and audio regions overlap when recording with autodrop

Say you are playing a melody for notation purposes with midi. You record 2 bars. Region is 2 bars long. You learn the next 2 bars and notice that this phrase actually starts at bar 2 beat 4. So you set autodrop to bar 2 beat 4 and punch in. The new region begins at bar 2 beat 1. If you adjust the region start point you see the end of the first region hiding behind it. In the score window, before trimming that new regions start point, you see rests for the new region and notes from the first region together..really lame. If you trim the new regions start point to bar 2 beat 4 it looks right. This is in replace mode mind you.... Why doesn't the punch appear at the autodrop location instead of at the beginning of the bar. I don't remember logic working like this before, did it? Seems like it was doing the same thing with audio, had regions hiding all over the place behind punches...very confusing. I saw a similar post but it didn't seem to resolve this issue...Is it a bug?

A few things (and there aren't many) regarding capture recording... For me it's been a tried-and-true feature of Logic for a very long time and continues to work flawlessly.
How Capture Works (and some operational notes)
Logic continually captures any and all MIDI data from the time you hit PLAY to the time you hit STOP, even if you're not "in record". Notes, program changes, controllers, sysex, anything MIDI will get buffered as you play and are ready to be turned into a region once you hit your Capture k/c. You can play to picture, improvise, whatever, for a very long time and never worry about Logic losing any of what you played.
The KEY is that after you hit STOP, you must hit your Capture k/c before hitting PLAY again, because once you hit PLAY, the MIDI buffer is, out of necessity, be cleared.
However, you don't need to STOP Logic to use Capture. You can play along with a track and hit Capture at any time. Logic will create a MIDI region from what you played and continue capturing additional MIDI data from your real-time performance while Logic continues to run. So you can start Logic, play some stuff, capture, play some stuff, capture, all without hitting STOP. In this scenario, just remember that if you hit STOP at any point that you will need to hit Capture that last bit of your performance (if you hadn't done so already) before hitting PLAY again.
One other operational note that's really important...
CYCLE MODE: If Logic is set to cycle and the cycle wraps to the L-locator before you've captured your performance, you will lose what's in the MIDI buffer. Jumping back to the L-locator in cycle mode is the equivalent of hitting STOP and then hitting PLAY. This is probably the single most important thing to watch out for. I've lost a few good "noodlings" because I had my L-locator set too close.
Hope this helps. I'd be curious to learn of your Capture experiences and see what you guys think!
