OpenMPT 1.18 - Release Notes

OpenMPT has changed a lot since the last official release (version 1.17.02.54). This document should give a rough overview about the greatest changes in OpenMPT 1.18.

What's new?

General

Sequences: It is possible to have more than just one orderlist in the MPTM format now. This way, you can work on several tracks or subtunes at once using the same set of instruments. This is for example useful when working on game music. You can also convert your work back to the other formats - The sequences are merged into one orderlist then. Sequences can be managed comfortably from the treeview.
Support for new file formats: GDM (General Digital Music), IMF (Imago Orpheus), J2B (Jazz Jackrabbit 2 music) and 8 channel Startrekker modules can now be imported. Modules compressed with gzip can be loaded. Scala tuning files can be used with OpenMPT's tuning editor now. Support for other file formats was also notably improved: All PSM files (old and new Epic Megagames MASI) load correctly now, ULT (Ultratracker) and OKT (Oktalyzer) import is more accurate, XM files compressed with BoobieSequeezer or made with early versions of Skale Tracker load correctly, etc...
A countless number of playback behaviour fixes to maximise compatibility with ProTracker, Scream Tracker 3, Fasttracker 2 and Impulse Tracker, including a special "ProTracker 1.x" playback mode. Compatibility export features have been enhanced.
Support for ultra-low latency in ASIO mode, down to 1ms.
Time estimation in the WAV and MP3 export dialogs; improved MP3 export (including ID3 v2.4 Tags).
The panic button in the main toolbar can quickly cut all sample and VSTi voices.
Default directories for VST plugins and presets.
More customisable colours. Now, you can export your favourite colour scheme to a file and share it with your friends!
Some new options, including the ability not to reset the channels when the module is looping and sample playback indicators in the treeview.
Program settings are now stored in the Application Data folder by default.
More intelligent autosave behaviour, which does not autosave anymore if nothing has changed since the last autosave. A friendly reminder: The autosave and backup options should always be enabled; You will be very glad about them once OpenMPT really crashes or you accidentally overwrite a file.
New and updated keymaps with many new shortcuts!
The new cleanup dialog replaces the cleanup menu and offers more options. For example, the rearrange samples function is available again.
Redesigned several dialogs.

Treeview

It is very simple to switch to another module now: Simply click the module name!
Closing a module is almost as simple: Right-click the module name and select the appropriate context menu entry.
Sample and instrument playback indication icons. Has to be enabled from the settings.
Improved icons: Mute status is now displayed.
Sequence control including copying a sequence to another module.

Pattern Editor

The upper panel is a lot more compact now; The split keyboard settings have been moved to a separate dialog which can be called with a keyboard shortcut or through the main menu.
Parameter Control Notes: These new pattern events almost completely replace
```
Zxx
```
and
```
\xx
```
commands for VST parameter automation in the MPTM format. They are not bound to a specific channel or macro anymore; The pattern event stores all necessary information and can thus be moved around easily in the pattern. The format for those events is
```
PC(s) XX YYY ZZZ
```
, the parameters work as follows:
- A
```
PC
```
  "note" entry equals a
```
Zxx
```
  effect, a
```
PCs
```
  "note" behaves like
```
\xx
```
  .
- The instrument column (
```
XX
```
  ) contains the VST number (can be obtained from the VST list or through the context menu).
- The volume column (
```
YYY
```
  ) stores the parameter that is going to be automated, ranging from
```
000
```
  to
```
999
```
  (decimal).
- The effect column (
```
ZZZ
```
  ) stores the parameter value, also ranging from
```
000
```
  to
```
999
```
  (decimal).
Note Fade is a new note type in IT / MPTM modules, based on an unfinished feature in Impulse Tracker, displayed as
```
~~
```
. As the name suggests, this note fades out the instrument depending on its fadeout value (without releasing any envelopes). Therefore, it will not work in sample mode. Various players and trackers support this command already.
New combined effect in the MPTM format: Note Delay + Cut. Format is
```
:xy
```
, whereas
```
x
```
is the delay in ticks and
```
y
```
the amount of ticks after which the instrument will be cut off again (or more precise: the instrument will be cut off at tick
```
x
```
+
```
y
```
).
In the orderlist, multiple orders can now be selected at once (default multiselect shortcut: Shift). Order selections can be quickly rendered to a wave file using the context menu.
New paste modes: Overflow paste (which continues the paste in the next pattern if it reaches the bottom of the current pattern), paste flood (which keeps pasting the data again and again, until it reaches the bottom of the pattern) and push-forward paste (which pushes the already existing pattern data downwards, like in Impulse Tracker).
Improved MOD editing - now it should be almost impossible to write commands in the patterns that don't belong into MOD files. :-)
If no selection has been made, Shift-Clicking a point now draws a selection, starting from the previously highlighted pattern command;
The volume column effect
```
:
```
(fake velocity) has been removed.

Sample Editor

Sample drawing! Create new empty samples and doodle around in the sample editor to create cool chip samples, or fix small mistakes (f.e. peaks) in already existing samples.
Undo: Finally, you can now also undo sample modifications; there are up to 100 undo steps for each individual sample.
Mass export: Shift-Click the "Save" button to export all samples at once.
Duplicate sample: Shift-Click the "New" button to clone all settings and the sample itself into a new sample slot.
DC Offset Removal: Samples can now be aligned perfectly to the zero line, to allow maximum amplification.

Instrument Editor

The envelopes can now be edited using the keyboard; some of the default keymaps already have the necessary shortcuts assigned - if you are using a custom keymap, you might want to add those shortcuts to it using the keyboard setup.
The sample map (IT / MPTM format) is now also applied to VST instruments. This way, you can easily transpose a VST instrument up or down. Some entries have been added to the sample map's context menu, to simplify this.
A basic envelope zoom feature; Might still look a bit weird at extreme zoom. :-)

VST Plugins

Pressing Shift while changing a plugin parameter in the plugin's GUI will open the MIDI Mapping dialog. Does not work with all plugins.
Enhanced VST compatibility.

Known Issues

This list has mostly been copied over from the old 1.17RC2 release notes, so this not very comprehensive... :-)

Lacking support for VST 2.4+
Some controls are vanishing randomly all the time, most notably under Windows Vista and Windows 7.
Previewing samples from the treeview's file browser stops the playing module.
Cannot preview instruments directly from the MIDI library in the treeview.
Excessive performance drop when dragging over the graphical parameter editor during playback.
The Right Alt (or Alt Gr) key is not handled well by the keyboard configuration.
In Windows 98, the graphical parameter editor and instrument envelope editor grid display are messed up.
There is no real 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...
