The Autodrop locators allow for numerical input in the Transport window.

The beginning and end of an Autodrop zone can be set in the bar ruler, as well by using the locators in the Transport window. Remember that theAutodrop locator points in the Transport window are located ton the right side of theCycle locator points.

Tip: A smaller Autodrop zone can also be defined within a larger Cycle zone. This works very well when a musician must replay a difficult passage in the middle of the song, and many takes are necessary.

Recording in Cycle Mode

Audio can be recorded if Cycle Mode is turned on. For each cycle, Adat Edit creates a new track object of the same type, so that for 10 cycles there will be 10 audio tracks of the same type, with 10 regions. You may then select the best take, and delete the others.

After Recording, Please Note…

After audio has been recorded, it is not a good idea to change the tempo. The Tempo should be determined before the first audio recording. Audio recordings have a constant playback rate, and it is very difficult to adapt them to a new tempo. Time Compression or Expansion Algorithms in other programs may affect the sound quality of the audio files negatively.

It is not generally recommended to move the anchors of regions

Adjusting Tempo Automatically

Adat Edit provides a function for adjusting the tempo of your song to a pre recorded audio file. For this to work properly, the audio file must be a steady tempo, and must be a known number of measures long. This command is called up from the

menu.

Digital Mixdown

Audio data can be mixed together digitally in the Arrange window (Digital Mixdown), by using the glue tool. This function is not destructive, because Adat Edit creates a new audio file, based on the selected regions. The new audio file will be stored on the hard drive – the memory capacity of the drive should constantly be monitored.

To execute Mixdown, select the glue tool from the tool box, and select the desired regions. Click on one of the regions, and they will be merged.

Mixdown for the regions on a track

When many regions are selected on one track, and these regions are not contiguous, the program will not execute Mixdown. Instead, the program will request that new data be created (named after the first region), and the selected regions will be mixed together without any volume change or level check (Clipscan).

Any empty space between two regions will be written to the new audio file as silence.

Functions

Real Mixdown with Clipscan

If audio data from two or more tracks is combined, the mixerl settings for pan and volume on each track will determine the pan and volume levels in the new audio file. If both sides of a stereo audio file are to be merged to mono, set the pan position for both channels either completely to the left, or completely to the right. Automated changes in level or pan will not be recorded by Digital Mixdown. To achieve this, the Bounce function should be used, instead. This is explained later in this section.

Mixdown can be executed during song playback.

After the digital Clipscan and Mixdown are complete, Adat Edit will replace the region that is currently selected with a region generated from the newly merged audio file. With the Undo function, the original audio regions can be brought back, and the program will ask if the newly created audio file should be saved (keep), or erased (delete).

During Mixdown, Adat Edit automatically maintains the highest possible level – without clipping – and processing is done with 32 bit resolution.

Bounce to Disk

In many cases, the Bounce to Disk function is better for accomplishing digital mixdowns. Automation, and effects are reflected in the audio material resulting from a bounce.

A Bounce button on the Output object of the Mixer (Master) will execute this function. A window will open, where you may name the bounced file, and set a destination for it on the hard drive.

Tip: When only dealing with a few regions or tracks (or only a certain area), the regions or tracks affected should be switched to solo, or the locators should be set to the respective area. This will limit the bounce to just the part ofd the song yopu wish to mix.

The Mixer

9.1Integrating Midi and Audio

An essential characteristic of the new version of Adat Edit is the adaptive mixer – which configures itself automatically to reflect your track list, and displays Midi and audio channels in the same way. The mixer has a three-bandequalizer for audio channels, and two auxiliary sends for internal effects. Any Midi object can be mixed using the standard GM (General Midi) controllers.

Opening the Mixer

In order to open the integrated Adat Edit mixer, select Windows > Open Mixer, or use a Key Command for this function.

9.2Midi Objects

Besides offering control for audio objects, the mixer has easy- to-useoptions for controlling Midi tone generators directly in Adat Edit. The control options for accessing a GM device (general Midi tone generator) are particularly flexible.

General Midi

General Midi is an extension of standard Midi, which prescribes certain requirements for tone generators.

Simultaneously receives 16 Midi channels

128 pre-setpatch locations for GM standard sounds

The Mixer

Pan and volume controlled by Midi for each channel

3 more freely selectable controller options per channel

All these functions are found on the Midi channel strips of the Adat Edit mixer.

Except for Program names, Chorus and Reverb, all Midi control functions can also be used for a tone generator that does not support the GM standard.

Try the following:

Open the Tutorial Song and start playback. A piano can be heard on Channel 1.

Move Fader 1 (click and drag the mouse).

The piano will become either softer or louder as the Fader is moved.

Click on one of the buttons for Channel 1, and move the mouse back and forth.

The value changes according to the vertical position of the mouse.

Technically, “Control Change” produces Midi events. These are processed by all Midi tone generators, but only GM tone generators are guaranteed to react to these Midi events in the way intended, if at all.

How a tone generator (not supported by the GM standard) responds to the GM mixer will depend on the Midi tonegenerator. Most Midi devices, whether GM or not, use standard controller assignments, such as CC#7 for volume, etc. The main discrepancy with most non GM devices is in program sounds. Non GM devices will not store sounds in the same order. For example, a non GM device may store an Organ sound in the first program location, rather than a Piano sound, as defined by GM.

Midi Objects

Bank Select

If your tone generator contains more than one bank of sounds, and if it responds to Bank select messages, then you can send a command from Adat Edit to switch from bank to bank on a per channel basis.

You can set the Bank select format that Adat Edit will send to your tone generator in the Song Settings. Check the documentation for the tone generator to determine which format is appropriate for that device. (see sectionBank Select on page 115).

A bank is a group of 128 sounds. Within each bank, sounds can be chosen from the program’s pull-downmenu.

GM Mixer Program

A sound can be chosen by name from the GM tone generator in the pull-downmenu, located along the upper edge of the channel strip. Every channel has its ownpull-downmenu.

Here’s how to select a sound for a Midi channel:

1.Click-holdon the Program name flip menu.

A pull-downmenu with all GM sound names will open up.

2.Select the desired sound from the menu, and release the mouse button.

Adat Edit will select the sound from the GM tone generator.

Volume

The Volume Fader controls the volume for each channel.

Click on the Fader, and drag the mouse.

Mute

The Mute button switches the channel volume from zero back to the preset fader position. This means that when the button is

2.Click the button once more to unmute the channel.

Pan

The Pan button regulates the pan position of the sound.

2.Drag the mouse up and down.

The knob will move to the right as the mouse is dragged up, and to the left as the mouse is dragged down.

Controller

Optional control data can be sent by using the three upper rows of buttons. A description of the pre-setController definitions follows.

Portamento

This knob turns on Portamento (one tone slides smoothly onto another), and controls the Portamento time. The further the knob is turned up, the longer the Portamento time. The minimum setting turns Portamento off.

Chorus

This knob controls the depth of the chorus effect. The further the knob is turned, the stronger the effect.

Reverb

This knob controls reverberation. The further the knob is turned, the louder the effect.
