I use Logic X on Macbook Pro late 2011 (the computer configuration is below). The trouble is that Logic causes CPU overload when using heavy plug-ins like Waves CLA pack or Izotope Ozone even in very simple projects. When a track is played, first i hear crackling noize and then one of two errors appears: 1) System overload 2) Error while trying to synchronize Audio and MIDI. Sample Rate xxx recognized. Check conflict between Logic Pro X and external device. (still no external device is used)
If you get an error message when you try to open the sound card mixer or nothing happens when you try to open it, this means that the selected audio driver doesn't have an associated Record or Play Control window. In this case, the audio device will usually have a separate control/mixer console that you can access from the Control Panel. You will need to check with your sound card documentation if you are not sure where to find it.
You select the Audio Driver type in Options | Preferences | Audio. You should normally check the "ASIO Always On" checkbox in the ASIO Audio Drivers dialog (the option is provided in case a particular ASIO driver has a problem with being on constantly - if unchecked, then it's turned off while your song is stopped). If you are using a DXi/VSTi synth, ASIO audio drivers, and have ASIO Always On enabled, you should be able to play your external MIDI controller and hear what you're playing with almost no latency through the DXi synth. You should find ASIO latency settings (also called 'buffer size') in the ASIO driver's control panel. A higher buffer size is 'safer' but more latency. You should start with a high buffer size and gradually reduce it until you start having problems, such as errors or audio glitches.
The Audio Delay setting in Options | MIDI Devices. This will delay the start of audio playback and audio recording, which is useful if you want to attempt to keep audio playback/recording in sync with MIDI, especially if you are using a software based synth for MIDI playback. Normally, you will set this to match the Synth (visual) Delay setting. If you are finding that the audio comes in before the MIDI (MIDI is slower), increase this setting. The audio will be delayed by the amount in milliseconds that you specify. You may have to experiment a little to find exactly the correct delay. Note that while the Synth Latency setting should normally be set to the same value as the Audio delay, the Synth Latency setting is quite different; it is only for keeping the visual display, such as displayed times and highlighting of notes, in sync with MIDI playback. It doesn't have any effect on what you actually hear.
You may also get the error "The waveform device can't play this format" when you try to play the file. This is most likely a sample rate problem. The sample rate is the number of audio samples taken per second; the higher the sample rate, the more samples per second and higher the quality of the file. Often the problem is that you have RealBand set to record at a higher sample rate than your sound card supports for playback. The audio file type setting is found in the Options | Preferences | Audio. You may need to choose a different file type. Check the documentation or settings for the sound card to determine what the sample rate is.
Yes you can. To record Digital Audio and MIDI at the same time, first make sure you have selected the correct recording input in the Record Control mixer. Select an audio track and simply start recording your audio while playing the MIDI device. If RealBand receives MIDI data while you are recording, it will be placed on the next available track. RealBand will also offer to put any recorded audio on the next available track if you are recording MIDI. You can enbable/disable this feature in Options | Preferences | Audio.
If you reduce the 'Output Buffer Milliseconds' value, the response to mixer moves will be faster. The lower the setting, the quicker the program will respond when you change volume, pan, mute, or effects settings for an audio track. 1000 milliseconds (1 second) usually is good overall setting for fast enough response, while still leaving enough buffers to avoid audible dropouts or clicks. If you have a reasonably fast CPU (over 1 GHz), try a 'Track Buffer Size' setting of 8192 and an Output Buffer Milliseconds setting of 500. This will reduce the buffering delay substantially.
If you are trying to install a program that you downloaded, you might get this error if the download did not finish properly or the file is corrupt for some reason. Delete the file that you downloaded, restart the computer, and try downloading it again.
This is usually because you have the application open when you are trying to install the update. Close the program and try installing the update again. If the application appears to be closed and you are still getting this error, reboot your computer.
The audio effects that you access via Edit | Audio Effects... are not real-time effects, which means that you have to add these effects while the song is stopped, and they take some time to process. These effects are also "destructive". This means that when you apply these effects to your track, you are permanently modifying the audio data on the track. What we suggest you do is to duplicate your track before applying one of these effects - that way you have a copy of the original track if you are not happy with the results.
The audio effects that you access in the Mixer window - ie, by clicking on one of the FX buttons - are non-destructive, real-time DirectX effects. You can apply these effects and make adjustments to them in real-time while the song is playing. You can experiment with them as much as you want without modifying the raw audio data on your track. 2b1af7f3a8
