In General

the track object in the mixer that is playing them is also set to stereo. If you play back the stereo file over a mono channel on the mixer, the information from both stereo sides will be summed together, and played back as mono. This can lead to unwanted dropouts or clipping.

Working with Audio in the Arrange Window

8.1Regions

Generating Regions

A region is to an audio track what a sequence is to a Midi track, so a region could be referred to as an “Audio Sequence.” The Adat Edit concept allows regions to be manipulated in the Arrange window in the same way as Midi sequences . Nonetheless, there are unavoidable differences between the two, by their very nature. A sequence contains Midi data, and a region refers to audio data on the hard drive.

When you record audio, a region based on the recording is automatically created in the Arrange window.

Audio files from other songs or other programs can be imported into a Adat Edit song. Simply click at the desired location for the imported file in the audio track, with the pencil tool, while holding down the Skey. Select the desired audio file from the File Selector dialog box, and the process is complete.

To play an audio file at a specific Song Position,it must be set as a region in the Arrange window.

Important: Remember that the tracks that contain regions should be assigned as audio tracks. More information can be found in the section Arming Tracks on page 193.

Dividing Regions

The Scissors tool used to divide Midi sequences can also be used for regions. When a region is cut, two new regions will be generated. The new regions will then be numbered consecutively.

Important: When you click on a region with the Scissors tool, you can precisely position the Scissors while click-holdingthe mouse button. If a finer resolution is needed,click-holdthe region with the Scissors tool and pressç(Mac) orA(PC). To obtain maximum resolution (ticks), hold downS while holding down the modifier key. The cut will be made when you release the mouse button.

Deleting Regions

Regions can be deleted the same way as Midi sequences. Select the region, and press the Bkey, or click on the region with the Eraser tool.

Deleting a Recording

If a region from a new recording is deleted, (any recording made since the song was opened for the current session), Adat Edit will ask if the corresponding audio file should also be deleted. By allowing you to completely delete unwanted takes, space on the hard drive is saved.

If you delete regions from files recorded in previous sessions, then this question will not be asked. This prevents any valuable recorded material from being accidentally deleted. If you want to delete any of these older files from the drive, first remove the regions from Adat Edit Song, and go through the computer’s operating system to delete the files.

Copying Regions

Creating A New Region

Regions can be copied and moved in the same way as Midi sequences. To move a region, simply grab and drag it. To copy a region, press the Okey (Mac) or theçkey (PC), while dragging the original. The new region will have the same name as the original region, and will be numbered consecutively.

The booundaries of the copied region can be changed, independent of the original. This can be compared to a real copy of a Midi sequence, created in the same way.

Multiple Use of an Existing Region (Alias)

It is also possible to generate an alias of a region in the Arrange window. In order to create an alias, press the Okey (Mac) or theçkey (PC), and theSkey simultaneously, while dragging the original.

If you edit one of these aliases, then all the other regions that were created from that same region will also be changed accordingly. This is comparable to an Alias of a Midi sequence, generated in the same way.

Looping Regions

As with Midi sequences, the loop parameter causes the region to play repeatedly within the track (see sectionLoop on page 178). It is important to note that the repetitions are guided by the region’s precise length. This means that even if the song tempo matches exactly, after a time, the repetitions may drift out of sync.

Working with Audio in the Arrange Window

Moving Regions

Just like Midi sequences, regions can be moved with the mouse in the Arrange window. When dragging a region, it will move in quarter note steps.

By pressing ç(Mac) orA(PC), regions can be moved in display format steps (e.g., sixteenths).

By pressing çS(Mac) orAS(PC), the regions can be moved by single clock ticks.

The delay parameter in the sequencer parameter dialog box can also be used (see section Delay on page 178).

Fine Movements

Usually, a resolution of one tick will be enough. If not, you can edit audio regions even more precisely in the Sample edit window.

Edits accurate to a resoultion of a single sample word can be achieved by moving the anchor in in the Sample Edit window.

Using the Event List to edit Regions

The Event list can be used to move regions numerically. Highlight the region, and then select Windows > Open Event List from the main menu bar. Using theposition column, regions can be positioned, tick by tick.

Even audio files in Arrangement window 2 can be displayed alphanumerically in Event List 1. Fine movement of regions is especially easy in the Event List.

Changing Borders

Regions can be lengthened or shortened by dragging the lower right corner. However, it is impossible to lengthen a region beyond the limits of the underlying audio file.

The same process, dragging the lower left corner, is used to adjust the start point of a region.

regions can be named at the same time, and a number at the end of the name will be appended to the sequences, to discriminate between them.

Loop

The Loop Parameter causes a region to repeat within the track, (as can Midi sequences). The region will continue to repeat until it encounters another region in the same track, or the end of the song.

Delay

Regions can be advanced or delayed with the Delay parameter. The delay is calibrated in increments of clock ticks.

Region Anchor

The anchor is a positioning reference point in the region. When a region is moved, the display will show the anchor point in the information line, instead of the start point, as with Midi sequences.

To guarantee perfect synchronisation with the sequencer, the anchor may need to be positioned within the region, and this position should be a peak, in most cases. Especially with drun recordings, this will allow you to move sections in the Arrange window so that the peaks fall on rhythmically logical points.

Recording

Some functions and parameters that are used for Midi events, can not be used for audio recordings.

Adjusting the anchor and destructive processing of audiofiles can only be done in the Sample Edit window.

Many important functions are the same for both audio and Midi, such as automatic naming of sequences, ability to change position and length, mute, solo playback, delay, loop etc.

8.2Recording

Setting Tracks to Record Audio

1. In the Arrange window:

Click on the round “Record Enable” button (R) of a PCR track in the track list in the Arrange window. This shows the status of theREC button on the audio track.

2. In the Mixer:

Open the mixer with the audio objects by selecting

Windows > Open Mixer.

Click on the REC button of the PCR audio objects you wish to record to.

Audio will be recorded only on tracks that are armed, regardless of which track the cursor happens to be on in the Arrange window.

If a Midi track is selected, Midi will be recorded.

If an audio track is selected, audio will be recorded on the PCR tracks that are activated as Record Enabled (armed).

Midi tracks and other PCR audio tracks can be recorded simultaneously by clicking on the Midi track, and then the audio track while pressing S.

Working with Audio in the Arrange Window

If more tracks in the Arrange window are assigned the same armed audio instrument (e.g., “Audio 1”), then the new audio file (or audio region) is recorded to the selected PCR track.

Disarming all Tracks

If many tracks are armed, clicking on the blinking REC button while pressing O (Mac) or the ç (Windows), will disable Record Ready for all tracks.

Recording Modes

Adat Edit offers several ways to start audio recording at a particular song position.

Standard Recording with Count-in

Recording can be started at any song position. Place the Song Position line to the desired spot, arm the audio track, set your input level, and click on Record.

Depending on the number of tracks that must be played back, there may be a small pause between clicking on the record button, and the start of audio recording.

Adat Edit automatically creates a region, based on the new recording. As audio is recorded, the waveform will be drawn into the Arrrange window in real time. You can also get an idea of the input levels in meters to the left of the track icon.

Manual Drop Recording

During playback, it is possible to jump into record mode. Start playback, and at the desired point, press the Vkey (this is thepre-setKey Command forRecord Toggle). Audio recording then will start, and can be stopped by pressing theVkey (in which case the sequencer continues to run), or by clicking on
