Audio and MIDI Files

You can view and manage all the audio and MIDI files on your device via the Files category in the Settings Page.

From there, use the File Browser to copy, move, rename, import or export files.

DOUBLE TAP on an audio file to open it in the Sample Editor.

Audio File Formats

Mono and stereo audio files at most bit depths and sample rates are supported:

• wav - Supports sample loop points, tempo, time signature and other metadata.
• aiff - Supports sample loop points only.
• ogg - An open source lossy compressed format.
• m4a - Lossy or lossless compressed format.
• mp3 - Lossy compressed format. You can load and edit mp3s but you must save them in a different format.
• mwav - NanoStudio's proprietary format for velocity split/round robin multisamples. You can load mwavs but you cannot edit or save them.

MIDI File Formats

The following MIDI formats are supported:

• Type 0 - All MIDI channels on the same track.
• Type 1 - Each MIDI channel is on its own track.

MIDI files may have a .mid or .midi extension.

File Locations

You are free to read or copy audio and MIDI files from most locations in NanoStudio's file system, but you only have write access (ie. save, delete, move, rename and create subfolders) in these folders:

• Library - This is your own area for files you use a lot and intend to use in more than one project.
• Project - This is the place to put files which will only ever be specific to your current project.
• Mixdowns - You can edit a mixdown using the sample editor and then save the new version back to this folder, or create subfolders to organize your mixdowns.

You can't directly write to or modify audio and MIDI files in these folders:

• Instruments - Instruments manage their own patches and any audio files they use.
• Other projects - You can only modify audio and MIDI files for the project you have currently loaded.

There are also two other special folders:

• Recent - Files you've recently loaded or saved.
• Trash - Files you've recently deleted. These may be deleted when the app isn't running if your device requires more storage space.

Library Inbox

You may see an Inbox subfolder in your audio or MIDI libraries. This is where NanoStudio places samples which have been exported to it (eg. when you select 'Open in NanoStudio' from another app).

If NanoStudio receives a zip file from another app which contains multiple audio or MIDI files, it will place them in a new subfolder within the Inbox so they don't get mixed up with other files.

When files are added to the Inbox, NanoStudio will notify you via the Status Bar. You're free to move them elsewhere using the File Browser.

Importing and Exporting Files

You can import or export audio and MIDI files via the File Browser.

There are also other methods available - see Integration and Sharing for more details.

NanoStudio will also import and export multiple files by placing them all in a single zip file.

Using Your Own Audio Files

To create an instrument patch using your own audio files:

• Place (or import) your audio files in the Library folder (create a subfolder for them if you wish).
• Tell the instrument to load them from the Library.
• Once you're happy with your patch, tell the instrument to save it.

Instruments always copy user files into the patch. This ensures the patch is unaffected by any changes you might make to your Library in future.

Factory and IAP files are not copied to patches as they never change or move. Instead, patches just save the path to where they can be found.

Using Your Own MIDI Files

To use your own MIDI files in a song:

• Place (or import) your MIDI files in the Library folder (create a subfolder for them if you wish).
• Use the Song Editor's MIDI Import Function
