2025-09-06T00:00:00+00:00

The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.8.3 (2025-09-06)

[Bug] libopenmpt is now compatible with most non-standard builds of libmpg123 which do not by default output signed 16bit PCM.
[Bug] openmpt123: Pausing playback using the space key did not work since 0.8.0.
[Bug] Windows 10 binaries wrongly targeted Windows 11 22H2. They now target Windows 10 2004.
[Bug] in_openmpt: in_openmpt for Windows XP or later did not ever work in Winamp 2.x. We now provide a build specifically for Winamp 2.x in the Winamp2/ folder inside the retro.winxp package. The retro.win98 build was not affected.
[Change] in_openmpt: Modern and legacy builds of in_openmpt now officially only support Winamp 5.x.
IT: Even when the filter cutoff envelope is stopped before its first tick is applied, the filter should still be activated.
mpg123: Update to v1.33.2 (2025-08-05).

[New] Makefile now supports DragonFly BSD.
openmpt123: FLAC multithreaded encoding has been enabled for Windows builds (https://github.com/xiph/flac/pull/822/).
Since libopenmpt 0.8.0, swapping between samples on the rear channels could introduce a click on the front channels.
IT: Volume column slides no longer propagate their effect memory to the regular effect column volume slides.
FC: Allow files with a sequence size of 0 to load (fixes a broken copy of cult.smod).

[New] 32bit ARM builds now support Windows 8 (Windows RT) again.
[New] libopenmpt: New APIs for determining whether order list entrys or pattern indices have a special meaning: openmpt::module::is_order_skip_entry(), openmpt::module::is_pattern_skip_item(), openmpt::module::is_order_stop_entry(), openmpt::module::is_pattern_stop_item() (C++), and openmpt_module_is_order_skip_entry(), openmpt_module_is_pattern_skip_item(), openmpt_module_is_order_stop_entry(), openmpt_module_is_pattern_stop_item() (C).
[New] libopenmpt: New APIs for retrieving pattern time signature information: openmpt::module::get_pattern_rows_per_beat(), openmpt::module::get_pattern_rows_per_measure() (C++), and openmpt_module_get_pattern_rows_per_beat(), openmpt_module_get_pattern_rows_per_measure() (C).
[New] libopenmpt: New APIs for retrieving the restart / loop position: openmpt::module::get_restart_order(), openmpt::module::get_restart_row() (C++), and openmpt_module_get_restart_order(), openmpt_module_get_restart_row() (C).

When formatting pattern data, effect letters in the volume column are now always formatted correctly, regardless of the module format.
IT: Various playback fixes.
IT: When using tone portamento to another sample after the previous sample’s sustain loop has been released, the new sample should also not play its sustain loop.
IT: When triggering an empty instrument note slot, completely ignore the pattern cell - do not reset the currently playing instrument’s envelopes, and also don’t process any effects - including global ones.
IT: Offset with instrument number but no note should play offset effect with previous note.
IT: Fixed various combinations of volume column and effect column portamento effects.
IT: Implemented a quirk in command Lxx that always executes a portamento down when no tone portamento has been set up before, sometimes causing the target note to be reached immediately, or sliding the note down very subtly.
IT: Envelope Carry should not be influenced by a previous note-off.
XM: When a key-off is encountered before auto-vibrato reaches full depth, the depth is reset.
S3M: Combined slides (Kxy / Lxy) are no longer run on the first tick of a row in files made with Scream Tracker.
MOD: Groo’s “The Ultimate Beeper” now plays like in ProTracker.
DTM: Portamentos are now also evaluated on the first tick of the row.
MO3: If multiple sample slots shared the same Ogg Vorbis sample, only one sample slot was loaded.

The pattern channel limit was raised from 127 to 192 for some formats.
openmpt123: Multi-threaded encoding is enabled with libFLAC 1.5.0 or newer.
xmp-openmpt: Memory consumption during file loading has been reduced.

libopenmpt releases 0.7.13, 0.6.22, 0.5.36, 0.4.48

2025-01-06T00:00:00+00:00

The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.7.13 (2025-01-06)

[Bug] Work-around broken user locale support on Cygwin.
module::get_current_estimated_bpm could return infinity when rows per beat was set to 0. A default of 4 rows per beat is now assumed in this situation. The internal LFO plugin was also affected in Tempo Sync mode.
Instruments that have a MIDI channel assigned and NNA set to “Continue” could cause NNA channel starvation.
In non-compatible linear slide mode, the sample rate could wrap around with portamento slides to extremely low frequencies. This should only happen in compatible mode.
mpg123: Update to v1.32.10 (2024-12-14).
XMPlay SDK: Update to 2025-01-03.

libopenmpt releases 0.7.12, 0.6.21, 0.5.35, 0.4.47

2024-12-01T00:00:00+00:00

The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.7.12 (2024-12-01)

[Bug] Fixed various undefined behaviour found with ubsan.
IT: Don’t report files claiming to be made with Impulse Tracker 2.08+ as IT-made if they have no edit timer.
IT: Ignore sample data in slots that don’t have the “sample data present” flag set, if the file vaguely looks IT-made to avoid playing garbage caused by an Impulse Tracker bug that should not be audible.
S3M: Detect early Schism Tracker versions.
MOD: When trying to detect MOD files with broken order lists, the file size is now rounded down to an even number. This helps identifying some malformed files (MOD files can technically not have an odd size).
MOD: Also enable ProTracker-compatible tremolo ramp waveform for M!K! modules.
MOD: In ProTracker 1/2 mode, retrigger with instrument-less notes now keeps using the previous sample offset.
Warn when a Startrekker AM file most likely requires an (currently unsupported) external instrument definition file.
DBM / IMF / MED: When merging pattern commands, allow to move offset to volume column at the expense of a lower offset resolution.
MED: Fix correct octave transposition in some MED files that have hardware mixing disabled but sample transpose enabled.
MED: Don’t enable Amiga resampler if any stereo samples are found, as it does not support stereo samples.
MED: Fix tempo in some files using software mixing mode and legacy tempo values.
MED: Avoid importing effect memory for some commands.
MED: Retrigger with instrument-less note now keeps using the previous sample offset.
MED: Disable sample swapping on notes with portamento, and don’t resume stopped notes with portamento.
MED: Only use 7-bit volume commands in MMD3 files made with a new enough version of MED Soundstudio.
STM: Do not sanitize sample loop data. Scream Tracker 2 reads into the next sample’s data when loops exceed the sample length.
When evaluating MIDI macros containing letters “u” or “v” during seeking, the initial global volume was applied to them, rather than the global volume that would be reached at that pattern position.
mpg123: Update to v1.32.9 (2024-11-02).

2024-10-26T00:00:00+00:00

The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.7.11 (2024-10-26)

[Bug] The Autotools build system did use CPPFLAGS, CFLAGS, and CPPFLAGS directly. This caused build settings to get lost when the user overwrote these flags.
IT: Don’t import SAx High Offset command for IT 1.xx modules. This feature was added in Impulse Tracker 2.00.
IT: Limit Vxx parameter to V80 for files made with old Schism Tracker versions.
IT / S3M: Impulse Tracker 2.14 patch version information was incorrect.
S3M: O00 effects are no longer ignored if the tracker version in the file header indicates Scream Tracker 3.00 / 3.01, but the file was clearly saved with another tool (e.g. UNMO3).
S3M: As files made with Scream Tracker 3.20 and 3.21 cannot be told apart, both versions are now listed in the tracker metadata.
ULT: Try to preserve global commands if there’s e.g. both a speed and tempo command in the same cell.
STM: Improved tracker identification metadata.
SymMOD: When running out of Zxx macros, try to find the closest macro to use instead.
SymMOD: Ignore unknown hunks instead of rejecting entire file, as that’s what Symphonie does as well.
OKT: Disable loop on type “B” samples if they’re used on a mixed channel.
OKT: The last sample slot was never loaded.
PTM: Halve offset command strength for 16-bit samples.
mpg123: Update to v1.32.8-dev+r5433 (2024-10-24).
