The wave editor can be entered by double tapping an existing or adding a new audio track in the track list.
It is also used for editing samples in a user instrument.
There are 5 ways to fill an audio track:
An audio track can only be linked to one audio file. Opening another file in the wave editor will link it to the selected audio track. Editing in the wave editor always changes the original audio file in the Audio folder, unless you tap the “Save as” button to save it under a new name. This improves the workflow by not having to save and type filenames every time you change an audio file.
The menu buttons to the left to the display (for playback and undo) and the zoom buttons are the same as in the Keyboard screen. The loop button toggles looping, but in the sampler mode it toggles the loop markers to set the looped sample range.
Tap the record button to open the audio recording popup for recording a wav file into the Audio folder.
See External Hardware.
By default, a file name that doesn’t exist yet in the Audio folder is displayed. Tap it to change the name of the file you are going to record.
The input gain fader is visible on top of the input levels only if your iOS device has input gain support or if the connected audio device offers input gain adjustment. Decrease the gain to avoid clipping, or increase it if the volume of your recordings is too low.
Tap anywhere on the input level bars to reset the clipping indicators. The red clipping indicators light up if the stereo input level bars hit full gain. This means that clipping has occurred and there probably will be a clipping noise in the recorded file.
Note: Only the levels of the first 8 input channels are displayed.
Input monitoring outputs the input audio signal before and during audio recording. There are 2 modes:
Note: to prevent feedback, input monitoring is only available if headphones or an external microphone are connected.
Note: Monitoring is not available if Audiobus input is selected.
With the internal microphone, only mono is available. If an external microphone or CoreAudio device with more than 1 channels is connected, the following options are available:
Listening to the song during recording is essential for singing or playing along. Situations where you wouldn’t enable this checkbox are if you start your song with an audio recording, or if you record snippets which will be used in multiple songs independently of the tempo.
Enable the metronome button to listen to the metronome during recording.
Note: If count-in is enabled in the metronome setup, it will kick in during audio recording too.
Tap the record button to start and stop audio recording.
Tip: Keep an eye on the input levels. Increase the distance to the microphone or decrease the input gain if they reach 100%.
Tip: If you want to trash the recording and re-recording, tap the undo button right after recording to delete the file.
The load audio file popup presents you with 4 options:
To save the current audio file under a new name, tap the save button and enter a file name. The original audio file will remain unchanged.
Tip: In many cases, enabling the Save selection only checkbox is more handy than using the trim button.
The delete button removes the current audio file from the Audio folder permanently. Undo is not possible after this action.
Tap the display or the ruler to change the units between seconds and measures (= bar.beat).
Tap the leftmost selection button and slide over an area in the wave form to select it. Use the markers on the ruler to adjust the selection, or tap one of the other two selection buttons to extend the selection to the beginning or the end of the audio file.
The trim button cuts the areas outside of the selection away from the audio file.
The delete button cuts the selected area from the audio file.
Place the playhead at the point where you wish to insert silence, by moving your finger on the ruler. Then tap the insert silence button and enter the length in seconds.
Tip: tap and slide your finger on the display to quickly adjust the length of the silence.
The reverse button reverts the selected area of the audio file, so that it sounds backwards when played back.
Normalization modifies the audio file’s volume to that the peak is at the desired percentage of the maximum volume.
Here are a few examples:
Limiter (soft knee)
The limiter checkbox becomes available at a percentage of over 100%, where clipping would occur. Applying a soft knee limiter prevents clipping (crackling), but it introduces some artifacts that reduce the quality of the audio file.
Tapping the fade in or out button unfolds a sub menu with 3 choices for the gradient: slow, linear, or fast.
The two most common cases are fading in the beginning and fading out the ending of an audio file. Try out the different gradients and tap the undo button in between.

Audiobus is an iOS app (available on the App Store) that enables app-to-app audio and MIDI routing between iOS apps that support Audiobus. Music Studio can send and receive audio and MIDI to and from other apps, through Audiobus. For more information see http://www.audiob.us
Music Studio is an Audiobus input and an output:
Audio workflow example:
(Unavailable in Music Studio Lite, only available in the full version) Inter-App Audio (IAA) was introduced by Apple in iOS 7.0. It provides universal audio routing across apps. It's not as reliable as Audiobus, but IAA doesn't require a separate app, in other words it's free. There are 4 kinds of Inter-App Audio apps:
Music Studio is a host, it can record and utilize other IAA node apps.
Generators produce audio can be recorded onto audio tracks. Many IAA instruments can also be recorded as if they were generators. Examples are drum machines or apps that don't feature a keyboard. To record an IAA generator app in Music Studio, add an audio track, tap the Record button and select "Inter-App Audio" instead of "Mono" as input source. A second menu appears where you can select all recordable IAA apps that are installed on your device.
IAA instruments receive MIDI from the host (Music Studio) and produce audio output. All installed instrument apps are listed in the Inter-App folder in the Instruments screen. They can be assigned to MIDI tracks the same way as internal instruments.
Effect apps process audio signals. All installed IAA effect apps can be selected as track, send or global effects.
