OpenMPT 1.31 + x64

Pattern tab
   [Imp] <js> Keep track of active SFx macro during seeking.

Instrument tab
   [Fix] <js> Importing soundfont instruments into IT / XM files did not remove the release node settings.

VST / DMO Plugins
   [Mod] <js> Prepend plugin name to default filename when saving a plugin preset or bank (http://bugs.openmpt.org/view.php?id=1108).

Playback
   [Fix] <js> The "note cut" duplicate note action did not volume-ramp the previously playing sample.

Other formats
   [Imp] <js> DSM: Support restart position and 16-bit samples.
   [Imp] <js> DTM: Import global volume.

Misc
   [Fix] <js> Possible crash when calculating song length in patterns with many nested pattern loops.

Third-Party Libraries
   [Mod] Update libvorbis (v1.3.6) and unrar (v5.6.2)

General

• Song cleanup can now merge identical patterns.
• Ogg Vorbis and Opus support is now built-in and no longer requires an external library for stream export.
• Add a new "MP3 (compatible)" export file type that is implemented only via libmp3lame and is the same as the old libmp3lame CBR mode with strictly ID3v1 tags only. The regular MP3 export mode uses more modern defaults for better audio quality.
• Added hidden setting Misc.DistinguishModifiers to distinguish between left and right modifiers (e.g. to create FT2-like play pattern shortcuts).

Pattern Editor

• Double-clicking an empty order list cell creates a new pattern.
• To make Data Entry more useful, it is now only applied to the first column type of selection, even if it spans several channels (e.g. if the selection starts in the volume column, only volume will be changed).
• Find & Replace can now find ranges of data (e.g. notes C-5 to D-6) and replace them also with relative values or percentages. PC events are now also fully supported by Find & Replace.
• When jumping around between patterns, plugin parameters affected by PC events are now updated.

Plugins

• Shift-clicking a plugin editor toggle button closes all other editors.
• OpenMPT now reads the VST plugin vendor. Searching for a plugin in the plugin manager also searches in the vendor names.
• When opening an instrument plugin editor, check if the currently selected instrument would be suitable input instrument for the plugin, rather than just the first instrument that uses this plugin.
• If available (on DirectX 9 and newer), DMO plugins now process in floating-point precision rather than 16-bit PCM.
• Plugin editor position is now restored properly on multi-monitor setups.
• The MIDI Input / Output plugin now sends MIDI Clock events. It is now directly integrated into OpenMPT and no longer shipped as a separate VST plugin.
• The DigiBooster Pro Echo DSP is now fully emulated and can also be used in other formats as a plugin.

Sample / Instrument Editor

• The resampler tool can now use any of OpenMPT's interpolation filters for resampling in addition to r8brain.
• Loop cross-fader now also works with sustain loops.
• Try to load SF2 instruments with left and right layer as stereo samples. Detuned SF2 samples are now finally fixed!
• Ogg Vorbis and Opus sample loading support.

Playback

• Instead of having one "compatible playback" per file, every playback quirk now has its own flag. This includes a dialog to edit these flags. These flags should not be edited manually, except for the "Set Defaults" functionality.
• For old files made with MPT / OpenMPT before v1.24, sample rates are now computed in periods again in linear slide mode. This fixes for example the drum line sample in Zanoma's "Late At Night". Similarly, old OpenMPT-made files that use portamento at speed 1 now sound as in OpenMPT 1.17 - 1.20 again.
• Each sequence now has its own restart position in the MPTM format.
• Parameter Extension (#xx) now also works with Position Jump command in the MPTM format, adding the possibility to jump order list items ? 256.
• Samples in MPTM files are now compressed by default (lossless IT compression).
• Extra fine portamento now works properly with custom tunings.
• Playing a sample at a sample rate close to the mix rate could lead to small clicks when using vibrato.
• If no instrument number was provided, New Note Action with empty sample slot and Duplicate Note Action sample checks were broken.
• Countless other playback fixes.

File Format Support

• Improved MT2 support.
• Support for SoundFX / MultiMedia Sound (SFX / MMS) and ProTracker 3.6 IFF-style modules has been added.
• Better tracker detection heuristics for Ultimate SoundTracker modules.
• MO3 support is now built right into OpenMPT, no longer requiring the closed-source UNMO3 on Windows 7 and newer.

There's more...Known Issues

• The plugin bridge is new and hasn't been tested very much yet. It is known that some plugins don't work in it at all. Custom plugin GUIs are known to not work in Wine. Please report any other issues you may be having with the plugin bridge!
• Far from perfect VST support (no buses for audio / MIDI routing, not all tracker effects are supported, etc...)
• Previewing samples from the tree view's file browser stops the playing module.
• Cannot preview soundfont instruments directly from the MIDI Library in the tree view.
• Excessive performance drop when dragging over the graphical parameter editor during playback.
• There is no really convenient way to find out what features of the tracker are supported by the original trackers (Impulse Tracker, Fasttracker 2, etc...) when working with those file formats...
