File Format Overview
At its core each DecentSampler sample library consists of two things: a folder containing a bunch of assets like audio files and pictures, and a single text file (called a dspreset file) which describes how the engine should use all of those files. This reference document is a guide to creating dspreset files.
dspreset files are just XML files. As such, each one begins with an XML declaration:
<?xml version="1.0" encoding="UTF-8"?>
The top-level <DecentSampler> element (required)
At the top level of every dspreset file is a <DecentSampler>
element. Every file must have one. Here is a list of attributes:
minVersion
(optional): This is the minimum version on which this preset is known to run. If a user is running an old version of DS, and a developer has specified a minVersion for their instrument, a dialog box will show up telling users that their version is outdated and that they should upgrade in order to get the full effect. They can than choose to ignore this warning or hit download. The dialog box does not show up for iOS users as most of them have auto-updates turned on.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<DecentSampler minVersion="1.0.0">
<!-- More tags go here. :) -->
</DecentSampler>
Underneath the top-level <DecentSampler>
element you can put any number of other elements, all of which are described in the sections that follow.
