PlayAlong Panel

You can play-along with a music in your iPod library.
PlayAlong panel can be used just like a music player; but there are some additional features that are useful for play-along.
To close the panel, tap the "Done" button at the bottom or swipe the panel to the right.

Load Song

To load a song to the player, tap the "Music ..." at the upper center.

The iPod navigation screen will appear, where you can select a song.
Note: If you access the iPod library for the first time from this app, you may be confirmed your permission.
After the selection and loading are completed, the controllers of the player are enabled.

The song duration time (playback time length) is shown in seconds on the middle band.
Also, a play-pause button will appear to the bottom right on the Main screen: described in the Player Control on the Main Screen section.

Eject

To eject the song from the player, tap the "Eject" at the upper right. A confirmation warning will appear; tap the "OK" to execute, otherwise tap the "Cancel".
When the player is empty, controllers of the player are disabled; the play-pause button on the Main screen also disappears.

Playback Control

When a song is loaded, the player is operable.

Controller	How it works
Volume slider	You can adjust the volume independently without affecting the device's volume setting.
Channel selector	Selects the channel that is convenient for play-along; normally "L&R".
	Toggles between playback and pause. Tip: Long-press makes the song replay from the marked time.
	Makes pause and returns the song to the beginning; also, when playback is completed, it goes the same.

Time Control

Current playback time and marked time are displayed in seconds at the left of the duration display in the middle band.

Controller	How it works
Time slider	The time slider position indicates the percentage of the current playback position. You can change the playback position by dragging the slider. While dragging the slider, the playback time reflects the dragging position, but the actual playback position changes when the dragging is released.
	Marks the current playback time. The marked time is shown in second above the Mark button in the middle band; default is 0 seconds.
	Replays the song from the marked time.

Player Control on the Main Screen

When a song is loaded on the player, the play-pause button will appear to bottom right on the Main screen.
That button works exactly same as the play-pause button on this screen; tapping toggles between playback and pause, and Long-press makes the song replay from the marked time.
