The "User Manual" is online in the Apple menu as Help (command-?). To help get you started, here is how the Controls palette works.
1. Play - Plays the sound. If the option key is held down, it plays the loop. To set the loop use command-L.
2. Record - Records a sound. When the record button is pressed, the recording process is automatically Paused. Press the Pause button to start recording. Select one track to record in mono and two tracks to record in stereo. You will get a warning if the sample rate or size is not supported by the input device. Make sure the "Sound In" Preferences are set correctly. You can also Resample to the correct sample rate and size. If the option key is held down, it will play the unselected tracks while recording (overdub). After recording, you will need to offset the recorded tracks to the left to put them in sync with the other tracks. Use the Track Offset Tool or delete the unwanted area. You will probably need to use headphones so the sound your listening to doesn't get recorded too. Pausing is not allowed when overdubbing.
3. Shuttle - With the Shuttle you can fast forward or rewind at speeds up to 32 times faster or slower. Click on the Shuttle and move the mouse to the left to rewind, and to the right to fast forward. The farther you move the mouse the faster it will go. Hold down the option key for slow motion. If you hold down the Command key, it will "lock" the speed when you let go of the mouse. You can use the Shuttle whether a sound is playing or not. If a sound is not playing and no part of the sound is selected, the cursor will be left at the point shuttling stops. The Shuttle range is set by the "Sound Out" Preferences with the Rewind and Fast Forward settings.
4. Tools - The Track Offset tool is for shifting the track horizontally or vertically (option key). The Eraser tool is for erasing parts of a sound. The Pencil and Line Tools are for drawing sounds.
5. Speaker Volume - Controls the speaker volume when playing sounds or the play through volume when recording sounds.
6. Mouse Coordinates - Shows the position of the mouse.
7. Selection and Loop Points - Shows the selection and the loop points.
8. Sound Length - Shows the length of the sound. While selecting part of the sound or if the Caps Lock key is down, it shows the length of the selection. While playing a sound, it shows the position of the play cursor.
9. Sample Size/Rate and Free RAM - Shows the sample size/sample rate, and the amount of free RAM in thousands of bytes.
10. Select Track - Toggles the selection of a track. If the option key is held down, the track is hidden. Click on it again to show the track. If the control key is held down, all of the tracks are selected. In the picture above, 1 and 2 are selected, 3 is not selected, 4 is not selected and is also hidden. You can also toggle the selection of a track by holding down the option key and clicking on a track, or select all of the tracks by holding down the control key and clicking on a track. Hold down the shift key and click on a track to change the selection length.
11. Solo Track - Toggles the Soloing of a track. If the option key is held down, the other tracks are hidden or shown.
12. Mute Track - Toggles the Muting of a track. If the option key is held down, the track is hidden or shown.
13. Boost Track Volume - Toggles the volume Boost of a track (doubles the amplitude). If the option key is held down, the other tracks are hidden or shown.
14. Track Volume/Level Meter - While playing sounds, it controls track's Volume and shows the track's output level. When the red light comes on, it means the sound is at or above the maximum level. When the Boost is off the range is 0 - 100%, when it's on the range is 0 - 200%. When the option key is held down, all the sliders will be moved. While recording sounds, it controls track's input Gain and shows the track's input level. When the red light comes on, it means the sound is being clipped. When the slider is centered the Gain is 100%, far left 50%, far right is 150%. If no slider is visible while recording, either Auto Gain is on in the "Sound In" Preferences or your Mac doesn't have input gain control.
15. Track Pan/Delay - Controls the track's Pan and Delay when playing stereo sounds. With the default "Sound Out" Preference settings, each step (pixel) equals one millisecond, so you can delay it from 1 to 31 milliseconds. When the option key is held down, all the sliders will be moved.
16. Output Volume/Level Meter - Controls the output Volume for the left and right channels. When the red light comes on, it means the output sound is being clipped. Some clipping is normal, but too much causes distortion. When the option key is held down, both of the sliders will be moved.
