The information covered in this section includes all application and project settings that exist in the Acoustic Labs Multitrack Plus. All settings can be accessed by selecting the "Settings" pulldown menu (visual aid item #1). These settings include the project settings, application settings, color settings and metronome settings.

  • Project Settings

    Multitrack Plus Project Settings Selecting "Project Settings" from the "Settings" pulldown menu option (visual aid item #1) will open the project settings dialog box as shown in the image to the right. Project settings includes the project description data, volume level adjustment and tempo and pitch adjustments.

    The project description data consists of a title, artist, album, year, genre and description. When saving or mixing down the project to an MP3 file, this information will be used in the MP3 file's ID tag. The volume level controls handle the overall or main volume of the project when playback is performed. As shown, the volume can be adjusted by either left channel or right channel. Using the "Lock Left and Right Channel" option when adjusting the volume applies changes equally to both channels. The project's tempo and pitch values can also be controlled in the project properties. There is no difference between controlling the tempo and pitch at this location than adjusting it in the Track View Interface as explained in Section 5: The Track View Interface in Detail.

    Application Settings

    Multitrack Plus Application Settings Selecting "Application Settings" from the "Settings" pulldown menu option (visual aid item #1) will open the application settings dialog box as shown in the image to the right. Application settings include general audio settings, general application settings, tempo and pitch processing settings and the playback buffer size setting.

    The general audio settings consist of the audio path, output device, time display and the extended playback amount. The audio path is the directory path where all temporary and saved digital audio is kept. The audio path is needed due to the extremely large size audio files can become in size. It is not possible to save all digital audio data to one file, therefore all digital audio snippets that exist in a project must be saved as separate files. These files are kept in the audio path. The output device is the audio output device that is being used for playback. If more than one audio output device is installed in your PC you can select the desired device for playback using the drop down select list. The time display setting controls how time values are displayed in the different interfaces. There are two options: Standard and Tempo. Standard time displays in a minutes, seconds and milliseconds format. Tempo time displays in a measures, quarter notes, sixteenth notes format.

    The general application settings control activating the snap-to-grid option, applying project settings to audio editor data and using realtime tracking during project playback. The snap-to-grid option applies to the Track View Interface. When viewing the Track View Interface you'll notice that the time bar (visual aid item #17) displays grid-like measurement marks. When the snap-to-grid option is selected, snippet movement will occur only in line with the measurement marks. When the time display is set to tempo, this is very useful for keeping snippet movements in proper tempo time. The next checkbox setting will allow project settings of audio snippets to be applied when viewing and playing back audio in the Audio Editor Interface. For example, if an Extended Audio Snippet is being edited in the Audio Editor Interface and it has realtime audio effects and/or a different internal tempo than project tempo these settings will be applied to the audio in the Audio Editor Interface. This is useful when attempting to edit audio while keeping in mind how it will sound during project playback. The final checkbox will allow for the view in the Track View Interface to follow the audio that is currently being played back.

    The tempo and pitch processing setting allows the user to choose between a higher quality of tempo and pitch adjustment verse processing time it takes for the tempo and pitch adjustment to be made. There are five different levels for this setting. Level 1 is the best quality and the slowest processing. Level 5 is the worst quality and the fastest processing. Depending on the PC's specifications, processing time may become a factor when mixing many tracks at once. If any audio playback or record problems begin to occur, increasing the level may help resolve the problem.

    The playback buffer size setting allows the user to choose the size of the playback buffer. Increasing the buffer size will allow for less chance of any interruption in playback or record of audio data. However, this will also result in an increased latency. When applying changes to levels and effects of audio data in realtime, latency is the time that it takes for the adjustment to take effect in the audio output.

    Color Settings

    Multitrack Plus Color Settings Selecting "Color Settings" from the "Settings" pulldown menu option (visual aid item #1) will open the color settings dialog box as shown in the image to the right. Color settings apply to the color of the waveform, the background of the waveform display and the color of markers used in the Audio Editor Interface. As you can see in the image different color settings can be applied to each audio track in the Track View Interface, each audio loop in the Loop Bank Interface and any audio loaded into the Audio Editor Interface. The "Waveform" setting controls the color of the actual waveform. The "Outline" color applies to the outline of the waveform. The "Background" color applies to the color of the background of the waveform and the "Markers" applies to the color of the markers in the Audio Editor Interface.

    Metronome Settings

    Multitrack Plus Metronome Settings
    Selecting "Metronome Settings" from the "Settings" pulldown menu option (visual aid item #1) will open the metronome settings dialog box as shown in the image to the right. Metronome settings control how the built-in metronome behaves when recording new audio to a track from the Track View Interface. The metronome can be turned on or off using the radio buttons located under "Metronome Status".

    The type of beat used for the metronome can be set in the "Metronome Beat Type" option. There are two general options: a typical drum machine type beat of a bass drum, snare and hi-hat cymbal or the user can choose the classic click that mimics the familiar type of clicking sound that is common with most metronomes. Many people find that it is easier to keep rhythm with a beat, therefore we incorporated the drum machine type beat into the Acoustic Labs Multitrack Plus. The volume of the metronome can be controlled under the "Metronome Volume Settings" control. The volume is in units of decibels. A decibel level of 0 is a normal volume level, a negative decibel level is a quieter volume and a positive decibel level is a louder volume level. The "Accent the first beat" checkbox will make the first beat (or click) of a measure slightly louder than the other beats. This usually helps people keep tempo easier.
