Importing Samples

Napo 5.9, first used in EuleOrgan 1.0, introduces the following new functionality:

Storage Locations for Samples

Some more explanations concerning the three locations that can be used as repositories for samples files:

Resources

The Resources are part of the delivered app bundle. They are read-only for the app, and files therein are not intended to be accessible to the user. At each update of the app, the Resources are downloaded again and replace the previous version. In the Napo apps that were developed before Napo 5.9, the Resources contain all needed sample files. This is why each update of these apps induces the download of a large amount of data, which is a nuisance that we would like to get rid of in future apps.

Library

The Library is a place where the app can save data which should be kept at app updates. It, too, is not intended to be accessible to the user. In Napo 5.9 and later, imported sample files are stored in the Library. If a sample file is present in the Library, then this file, and not the version in the Resources, will be loaded.

Documents

The files in the Documents are accessible to users via the Files app (iOS) or the Finder (macOS). They are preserverd, too, at updates of the app. If a sample file is present in the Documents, then this file, and not the version in the Library or in the Resources, will be loaded. Beware: If you add sample files to the Documents, a Napo app will detect this only at its next start, and if you change or delete samples files in Documents while the app is running, it probably will show error messages and need to be restarted. Except from special circumstances or for temporary purposes, we do not recommend to use the Documents for storing sample files. Better import the files to the Library. However, if you want to place sample files in the Documents, this must be done in a specific directory structure that is described below.

In the Info tab of the Settings view there is an entry File statistics and a button Show. This shows an overview of the number and size of the sample files in each of the three possible locations, broken down to 16 and 24 bit files, and additionally there is information on files that are currently used by the app. The buttons Show all files and Show used files give more details. For example, when you have imported all stops with 24 bits in EuleOrgan, the table looks like this:

As you can see, the 16 bit files that were delivered with the app within its Resources are not used anymore. Instead, the app is using the imported files that are in the Library. There are eight 16 bit files in the Eule Szombathely sample set. Napo does not convert these to 24 bits as this would not have any use. Napo can happily work with a mix of 16 bit and 24 bit files.

If you would have done the import with 16 bits, then the app would have imported only those files that are not included in the Resources.

Import Functions

After choosing the entry Importing Samples of the action menu of the Settings view, you get another action menu with following entries:

Directory Structures

Unless you would like to create import sources yourself or use the Documents as a sample files repository, you do not need to care for the following.

Directory Structure in Import Sources

A Napo app can handle import sources (directories or RAR/ZIP archives) where the files are layed out as in the sample set that the app is based upon. Only the last components of the file path matter. Taking two files of EuleOrgan as example, the following structure is expected, where xxx is arbitrary. For the main file:

    xxx/near_dry/I-01-Prinzipal8/036-c.wav

For the release file:

    xxx/near_dry/I-01-Prinzipal8/L/036-c.wav

At this time, EuleOrgan is the only app where the releases are in separate files and the main file contains only the attack and loop part. For the other apps, there is just the main file, containing attack, loop, and release.

Directory Structure in the Repositories

In the repositories, the files are in a subdirectory Samples. This means, if you would like to drop sample files in the Documents directory, they must be organised like this (again using EuleOrgan as example):

    ./Samples/near_dry/I-01-Prinzipal8/036-c.wav
    ./Samples/near_dry/I-01-Prinzipal8/L/036-c.wav
