Now choose Add Soundfile from the File menu. When you have selected a
soundfile, use the OK button to load the file into MIX.
The sound will appear in red at the top left corner of the tracks area.
You can then select
another file, and again, use the OK button to load it. Click the Cancel button
to close the dialog box. Now use the right mouse button to move the sounds
around. You may move the sounds from one track to another.
The pan graphs work very much the same way as the volume graphs.
Panning is to the left when the graph is at the bottom.

Add one or more soundfiles (i.e.
soundfile references) to the current mix. Mix displays a dialogue box,
where you can select a soundfile to be included. When you press the
OK button, the selected soundfile is placed in the top
left corner of the current mix. Quite often you may end up with
several soundfiles that are placed on top of another, looking like only
one soundfile. To avoid this, you should move a sound file to another
position (using the right mouse button). Also, you may use the radio
buttons to place the new sound on a track other than the first. To add
more soundfiles, simply
press the OK button more times after you have selected
a soundfile. The dialogue box stays open until you press the
Cancel button.
If the sample rate of the soundfile does not match that in the audiosettings pane, you will be asked whether you
want to convert the soundfile. Converting the soundfile means the soundfile
on your disk will be converted.
The original soundfile will be copied to a file with
the extension .bak.
If you select Cancel, you should make the Sampling Rate setting in the
Settings:Audio menu match that of the sound file.

Using MIX
This section gives you a quick introduction to working with MIX.
For reference on menus and mix files, see the relevant sections
(after this section).
Preparing for a MIX session
First, you must have one or more soundfiles to work with, as
MIX has no facilities for recording or creating these sounds
(the new Record feature is not very useful yet).
The soundfiles must be in AIFF or AIFC format.
If you have soundfiles in other formats, use the soundfiler program
to convert these to AIFF or AIFC.
It will also make things easier if the files have the same sample rate.
Starting MIX
Start MIX. On the screen you will see 9 tracks, each with control buttons
to the left. The ruler above the tracks shows time in minutes.
Use the scrollbar and the magnifying glasses at the bottom of the screen
to change the view.
Changing volume and pan
Use the volume fader to left left of each track to change the master
volume of each track. To mute a track, click the MUT button, which then
appears in red. To "de-mute", click it again.
Volume graphs
MIX offers flexible control of a track's volume with the volume graphs.
Do as follows: Click the VOL button. You will now see a green graph in the
track area. The shape of this graph is an "envelope curve" which controls the
volume of the track. "Click actions" on the graph is done with
the middle mouse key only.
Things you may do on the graph:
Note that there is an end node which follows the position of the last node
but one.
Adding effects
The effects system in MIX is still at an experimental stage.
The architecture is somewhat unorthodox in that the aux send is pre-fade.
This means that you can adjust the track volume fader to suppress the
original sound while still hearing the effect.
To add effects to a track:
At the moment, MIX offers these effects:
Effects Box 2 is just an extension of Effects Box 1.
Buttons
Track Buttons
The Mut button mutes the track. The Vol and Aux
buttons are used to show the appropriate value graph on the track.
Pressing the track number button will solo that track, and it will
fill the screen (a rather useless feature).
The Menus
The File Menu
Add soundfile:The Edit Menu
The only option here is an "undo". This will load an entire backup file
from scratch, and is therefore time-consuming. Also, this function has
ben known to crash the program!
The Settings Menu
The Effects Menu
Menu choice:
The Tools Menu
The Variables Menu
The Graph Menu
The Group Menu
The group function enables you to work on several sounds at the same time.
First you select a number of sounds, which will appear in brown. Then select
