Editing OpenMPT (section)

== Features ==
OpenMPT's main distinguishing feature is its native [[Microsoft Windows|Windows]] [[user interface]]. Most trackers, even newer ones such as [[Renoise]], have interfaces modelled after the older [[DOS]] trackers such as [[Fast Tracker|FastTracker II]]. It supports samples, [[Virtual Studio Technology|VST plugins]] and [[Yamaha YMF262|OPL3]] instruments<ref>{{cite web|url=https://openmpt.org/openmpt-1-28-01-00-released|title=OpenMPT 1.28.01.00 released |date=2018-12-23 |access-date=2020-05-29}}</ref> as sound sources.
OpenMPT makes use of features common to Microsoft Windows programs, such as context menus for effect selection, "tree" views (for files, samples, and patterns), [[drag and drop]] functionality throughout, and the native [[look and feel]] of the Windows platform.

It supports both loading and saving of IT ([[Impulse Tracker]]), XM ([[FastTracker 2|FastTracker]] Extended Module), MOD ([[Protracker]] and similar), S3M ([[Scream Tracker|Scream Tracker 3]]) and MPTM (its own file format) files, imports many more module and sample file formats, and has some support for [[DLS format|DLS banks]] and [[SoundFont]]s.<ref name=ompt/>

OpenMPT was also one of the first trackers to support opening and editing of multiple tracker modules in parallel. OpenMPT supports up to 127 tracks/channels, VST Plugins, VST instruments and has [[Audio Stream Input/Output|ASIO]] support.<ref name=ompt>{{cite web|url=https://openmpt.org/features |title=Features |date=2011-02-05 |publisher=openmpt.org |access-date=2011-02-05 }}</ref>

===MPTM file format===

Due to limitations of the various mod file formats it is able to save, a new module format called MPTM was created in 2007.<ref>[https://forum.openmpt.org/index.php?topic=1613.0 ModPlug Central Forums]</ref>

OpenMPT introduced some non-standard additions to the older file formats. For example, one can use stereo samples or add [[Virtual Studio Technology|VST plugins]] to [[FastTracker 2|XM]] and [[Impulse Tracker|IT]] modules, which were not supported in the original trackers. Many of these features have gradually been removed from IT and XM files and made available only in MPTM files.

===libopenmpt===

libopenmpt is a cross-platform module playing [[Library (computing)|library]] based on the OpenMPT code with interfaces for [[C (programming language)|C]], [[C++]] and other programming languages. To ensure that the code bases do not diverge like in the case of ModPlug Tracker and libmodplug, libopenmpt development takes place in the same [[Repository (version control)|code repository]] as OpenMPT. Official [[Plug-in (computing)|input plug-ins]] for popular audio players ([[XMPlay]], [[Winamp]] and [[foobar2000]]) based on libopenmpt are also available from the website. [[FFmpeg]] also offers an optional module decoder based on libopenmpt.<ref>[https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/libopenmpt.c libopenmpt demuxer in libavformat]</ref> libopenmpt can also serve as a drop-in replacement for libmodplug and thus offer up-to-date module playback capabilities for software that relies on the libmodplug [[Application programming interface|API]].<ref>[https://packages.debian.org/de/sid/libopenmpt-modplug1 libopenmpt-modplug1 in the Debian package repository]</ref>
