Project button: Opens a pop-up menu where you can import audio/MIDI files, load/save or mix your projects, etc. If you start up the program, the project is called 'Untitled.prj'. When you choose to save the project, you will be asked to enter a new name. Choosing 'Save project' subsequently, will just save under the new name.
Scroll button: puts the program in 'Scroll' mode. This mode allows you to view your project without any risk of altering any audio or MIDI region, which can be very convenient. See the section on Editing for more information.
Edit button: puts the program in 'Edit' mode. This mode allows you to move and trim audio/MIDI regions. See the section on Editing for more information.
Split mode button: puts the program in 'Split' mode. See the section on Editing for more information.
Range button: Puts the program in 'Edit range' mode to perform cut/copy/paste operations. See the section on Editing for more information.
Remove button: Puts the program in 'Remove' mode. See the section on Editing for more information. Note: when Automation mode is active as well, you can delete automation points by sliding your finger near the point(s) you wish to remove.
Automation button: toggle to switch between normal and automation mode. See the Automation section for more information.
Undo button: every edit on regions on the time line can be un-done. This is particularly important, because editing on phones or tablets can be less accurate than on desktops, so a mistake is made more often. Press once to go one step back in the editing process. The undo stack is unlimited, so you can undo all the way back to when you started editing.
Redo button: similar to the Undo button, but re-applies what you have just un-done.
Cut/Copy/Paste buttons: use in combination with the 'Range' button. (only available on large tablets)
Loop button: toggles loop playback on/off. When active, only audio/MIDI between the two yellow loop markers will be played back. When the time passes the yellow end marker, playback will continue at the yellow start marker, playing indefinately. You can also start anywhere within the loop range by putting the green marker in between the yellow markers.
Grid button: pops up a menu where you can select a certain grid to display and snap to. If a grid is selected, the editing features like move/split/etc. will be bounded to the grid you specified. Use in combination with the Tempo and signature settings dialog for aligning drum samples etc. The tempo dialog can be accessed by tapping the time indicator at the bottom of the display.
Jump To Marker button: pops up a menu in which you can choose where to jump to. The time marker will be set to this location.
Add marker button: inserts a marker (a blue numbered triangle) in the time code bar. You can use this to mark certain passages of a song or recording. Use in combination with the 'Jump To' button to quickly jump to these markers.
Next screen button: moves to the next screen. There are currently three screens in Audio Evolution Mobile: the arrange screen, the channel mixer screen and the master/group mixer screen.
Time line area: shows all your audio tracks. Use in combination with the top area buttons to edit or view your samples. When not touching a sample, but touching an empty grey area, you can scroll up/down/left/right your project view.
Hint: Long press a sample, an empty part of a track or outside the tracks to get a pop-up menu with more functionality!
Mixer channel: displays the mixer channel of the currently selected track. Tracks are selected when you perform operations on them or if you are in move mode and select a track. The mixer channel that is displayed here is only part of the full mixer channel. The mixer screen (entered by the green 'next screen' arrow on the top right) will allow you to view the full mixer channel. See the Mixer screen for a full explanation of the mixer channel.
Play from start: puts the timer marker at 0:00:000 and starts playback.
Play: starts playback from wherever the time marker (the green triangle) is currently located.
Stop: stops playback or recording
Record: starts recording from wherever the time marker (the green triangle) is currently located.
Time indicator: Displays the time where playback will start or displays the current time. Available in minutes:seconds:milliseconds or bars/beats. Note: tapping this area will pop-up a dialog where you can set the tempo and metronome.
Project overview / scrollpad: This area shows an overview of your project. The white lines indicate the length of your samples relative to the length of your project. Tip: move your finger over this part to scroll through your project fast!
