OpenMPT is an open source audio module tracker for Windows. It originally started out under the name ModPlug Tracker, and was developed by Olivier Lapicque in September 1997.[2]

OpenMPT was named by Computer Music as one of the top five free music trackers.[3]

History

ModPlug code origins

Originally called ModPlug Tracker, it was initially developed as a plug-in named MOD Plugin for Internet browsers,[4] to allow users to listen to music modules (for example, IT, XM, S3M, and MOD) present in some websites. ModPlug Tracker, along with a player application named ModPlug Player later evolved from this plug-in.[5]

In December 1999, Olivier Lapicque sent the module-playing parts of ModPlug Tracker's source code to Kenton Varda, under the GPL, to write a plugin for XMMS based on the code. The source code was in 2001 released in the public domain,[1] and the mod-playing code was split off into a separate library, libmodplug, maintained as part of the ModPlug XMMS Plugin project. This project lay dormant from late 2003 until early 2006, when it was picked up again. Today, libmodplug is included in many Linux distributions as a default audio plugin for playing module files and is a part of the popular OpenSource multimedia framework gstreamer.[6]

Due to lack of time, Olivier Lapicque discontinued development of ModPlug Tracker itself, and in early 2004, he released the entire source code under an open license. The ModPlug Player source code is still closed as of October 2014.

OpenMPT

Lapicque's MPT code was taken up by a group of tracker musicians/programmers and is now known as OpenMPT. Also based on the ModPlug code is OpenMPT's "sister project" Schism Tracker which contributed several backports of bugfixes to OpenMPT.[7]

OpenMPT is distributed as free software and is, as of November 2015, under active development. Until May 2009 (v1.17.02.53)[8] OpenMPT was licensed under the Copyleft GNU General Public License and then relicensed under the terms of the permissive BSD license. Since OpenMPT 1.23 (March 2014), OpenMPT is also available as a 64-bit application.[9] This allows musicians to use 64-bit VST plugins and make use of the entire physical memory on 64-bit systems. For this purpose, OpenMPT provides its own plugin bridge, which can be used to run plugins with a different bitness than the host in a separate process, or to run plugin in a sandbox and prevent them from crashing the host application.

Features

OpenMPT's main distinguishing feature is its native Windows user interface. Most trackers, even newer ones such as Renoise, have interfaces modelled after the older DOS trackers such as FastTracker II. 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 Extended Module), MOD (Protracker and similar), S3M (Scream Tracker 3) and MPTM (its own file format) files, imports many more module and sample file formats, and has some support for DLS banks and SoundFonts.[10]

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 ASIO support.[10]

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.[11] However, the format is still in experimental stage and is expected to be changed in the future.[12]

OpenMPT had previously introduced non-standard additions to the older file formats. For example, one can use stereo samples or add VST Plugins to XM and IT modules, which were not supported in the original trackers. Many of these features are gradually removed from IT and XM files and made only available in MPTM files.

libopenmpt

libopenmpt is a cross-platform module playing library based on the OpenMPT code with interfaces for the C and C++ 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 code repository as OpenMPT. Official input plug-ins for popular audio players (XMPlay, Winamp and foobar2000) based on libopenmpt are also available from the website.

Reception and users

Nicolay of the Grammy-nominated The Foreign Exchange has revealed that ModPlug is his "Secret Weapon".[13] Movie and video game music composer Raphaël Gesqua also revealed to use OpenMPT in an interview.[14]

Peter Hajba and Alexander Brandon used OpenMPT to compose the soundtracks for Bejeweled 2,[15] Bejeweled 3[16] and other PopCap games.

Electronic rock musician Blue Stahli has mentioned that he used ModPlug Tracker and other trackers in the past.[17]
