OpenMPT released

It's time for the next big OpenMPT release, and OpenMPT 1.24 again brings a great amount of long-awaited new and improved features. Here is a short summary of the most notable new features:

  • ITP is dead*, long live MPTM! No worries, your old ITP files can still be imported, but the clunky ITP format has been dropped in favour of some new features in the MPTM format: Instead of linked instruments, you can now keep references to external samples in your MPTM files, effectively reducing the file size even if a sample is shared by several instruments. The ITI instrument format has been extended in a similar way so that ITI files can now simply reference external sample files instead of directly embedding the sample data (choose "Impulse Tracker Instruments with external Samples" in the save dialog). Unlike in the ITP format, it is easy to mix external and internal samples in one file and relocate missing files.
  • Each song's window position and contents are now saved, so that you can continue right where you left off when reloading the file.
  • "Remove unused sample data" now also finds samples with identical stereo channels and offers to optimize them to mono.
  • Dropping a folder on OpenMPT that contains modules or VST plugins opens / registers them directly now.
  • Song length estimation can now show the length of all "hidden" subtunes in the current sequence.
  • Many small improvements in the audio output code again, also to improve performance on Wine systems.
  • In the pattern editor, Ctrl+(Shift+)Scroll wheel can now be used as a replacement for the "(Coarse) Data Entry" shortcuts.
  • Further enhanced drag&drop functionality in the tree view: Dropping a module or folder on the sample browser opens this module or folder for browsing, dropping a soundfont file on the upper part of the tree view adds it to the list of soundfonts.
  • In the tree view, sample waveforms can now be reloaded from disk (e.g. after editing a sample in an external application) if OpenMPT knows the sample's original path, e.g. after loading or saving it, or using MPTM's external sample feature.
  • When adding a new plugin through the plugin manager that is missing from some open file, it is now automatically loaded and restored in that file.
  • "Randomize Parameters" now applies a customizable randomization factor to plugin parameters.
  • Resampling samples to any custom sample rate is now possible, thanks to the high-quality r8brain-free resampler.
  • Adjusting the sample frequency updates all playing notes' sample frequency immediately (only in IT and MPTM).
  • Custom background and selection colours for the sample and instrument editor.
  • Rearranging samples (e.g. through song cleanup or the tree view) no longer messes up the undo buffer history.
  • When previewing instruments with a fadeout value of 0, instantly stop them on key-up instead of letting them play forever.
  • The first instrument of a soundfont can now be loaded directly without registering the soundfont in OpenMPT. Useful for single-instrument soundfonts.
  • S70 / S71 / S72 commands do now also work with instrument plugins. NNA / DCA settings are now applied to plugins assigned to sample-less instruments as well.
  • Smooth MIDI macros do now, to some extent, work with external MIDI messages. They interpolate from the previous Zxx or \xx parameter from the same channel to the new parameter.
  • In all mix modes since 1.17RC2, a way too long volume ramp (some times up to 100 times longer than the user-supplied ramp setup) was applied for extreme global volume changes. This is now disabled except for legacy 1.17RC2 mix mode.
  • Re-implemented stereo separation to be applied on the master mix. This means that it also works as expected with stereo samples and plugins now.
  • Linear frequency slide mode (in all formats except XM, which already worked as intended) has been re-implemented to fix some unwanted inaccuracies which can add up very quickly when using extra-fine slides.
  • Reverted XM compatibility export to always write out 256 order items, which should restore compatibility with a couple of players that were previously choking on OpenMPT's XM files.
  • Use "normal" compatible mix mode instead of FT2 panning mix mode for XM files that were compatibility-exported with OpenMPT 1.22 or older, and XM files made with other trackers that use linear panning.
  • Compatible playback mode for S3M: When enabled, OpenMPT emulates certain ScreamTracker quirks as it did until now (linked pattern effect memory and ignored effects on muted channels). Compatible mode is disabled automatically for files made with less compatible trackers. S3M files made with OpenMPT always have this mode enabled, and its state is not saved in S3M files.
  • Amiga frequency limits can now also be enforced in MOD files without activating ProTracker 1/2 mode.
  • Added loading support for a MOD variant introduced by SoundTracker 2.6 and Ice Tracker.
  • Completely rewrote MT2 loader. Some files that would previously not load properly do now load. Support for VST plugins, drum patterns and some extended MT2 pattern commands has been added.

* Not that anyone would have noticed - some fundamental errors in the ITP saving code have gone unnoticed since the release of OpenMPT 1.21 two years ago...

libopenmpt has been updated as well to reflect the latest improvements in OpenMPT. New features include independent pitch and tempo modification as well as better subsong selection control.

It’s so wonderful! I’ve been using OpenMPT for a several years, and it’s getting better and better yet relatively simple to use. Thanks!

I guess it’s time to create something…

Matthew says:

These releases keep getting better and better. There is just one thing missing......The ability to edit The effects row with out having to manually press down....I've been wanting this feature for a while. being able to edit the effects row with out having to manually press down I feel is NEEDED. It's just a thing that kinda keeps me from going in and actually dedicating to a song.

If this is a thing already then I can't seem to find this anywhere in the options.

Saga Musix says:

I guess you want this feature because you are used to how other (DOS) trackers work, but OpenMPT probably already has better and faster ways for you to do this. For example, you can enter your effect in the first row, then make a selection until the last row until which the effect should last, and then press Ctrl+K or whatever your "intepolate command" shortcut is - if the last row if your selection is empty, it will automatically repeat the first command from the first to last row. Alternatively, if you want your effect to last until the end of the pattern, you can copy the effect and then use the Paste Flood shortcut to repeat it until the end of the pattern.
This is simply much more efficient than keeping your finger on a key for 10 seconds until all rows are filled.

8BitZtuner says:

Is Midi export ever being concidered to be rewritten or taken off?
I mean, it's a cool feature, but it is not really helpful when pitch information, tempo info and all that fun stuff are not written down in the Midi file (FL Studio 10).
Will be ever good or just thrown off?

Saga Musix says:

Maybe, maybe not? I personally don't have any plans to do it anytime soon, but that doesn't mean that noone else will do it.

Cassualboy says:

I hear from several comments there are many request for enhancing MIDI support in OpenMPT. Unfortunately nobody want to program it and I myself doesn't have programming skill to do something.

If there is other thing than programming that I can do to improving MIDI support in OpenMPT, I 'll definitely do it.

Anyway ...

Synthfont, a good MIDI and SF2 player has VST version.
Does it means that OpenMPT will become a good MIDI Tracker if I use this VST plugin?

Casualboy says:

If I use , will it make OpenMPT read MIDI better?

Saga Musix says:

No, the only thing Synthfont does is playing Soundfonts. Soundfonts are usually arranged by the General MIDI standard, but that has absolutely nothing to do with OpenMPT's MIDI import.

DaVince says:

It's a pity that the MIDI export feature is low on the priority list. Even though it has a long-standing bug where the last half second of the music gets dropped from the MIDI entirely. If that gets fixed and volume changing gets implemented, MIDI export would be pretty much perfect for me. :P

Maybe I'll look at the code sometime (even though I'm not exactly a great coder).

Saga Musix says:

Nothing gets dropped, it's just that MIDI files end with the very last command, and if your last note is followed by nothing but empty lines, that last note is the last command.

Alfred Anthony says:

I was curious if there are any plans to add piano roll editing?
I know it would be very scaled down, but I find myself losing focus with the note numbers rather than seeing which note I'm working with on an actual 88 key reference grid. It would also be nice to draw durations and splines for other parameters instead of inputting the data voice by voice.

Saga Musix says:

It would make more sense to post this on our forum or issue tracker, but in short: No.
