The MusicWeaver— Revision History

Here is a (mostly unedited) record of the various releases over the years. It might give a picture of the way the suite has developed.

Release 2.8.4 for HAIKU — August 2014

In the fourth update, aside from a couple of bug fixes (to Splitter and Karaoke) the main enhancements were to MidiPlay and MidiFile. The former now preloads files in the queue so they are played without delay; the latter now allows setting a start event. Documentation was also updated a bit where necessary

Release 2.8.3 for HAIKU — July 2013

This is the third Haiku update. It mainly fixes a few bugs that turned up, and bad layout in some of the module panels (left over from BeOS). The main Weaver program and its Supported Types have gained new (vector) icons, a couple of modules have been upgraded, and one new one was added. See the README included in the package for details

Release 2.8.2 for HAIKU — January 2012

This is the second major update for use under Haiku. Just about all the modules have now been updated in one way or another to suit them for Haiku and remove the — mostly cosmetic — deficiencies in their control panels.

There is one major new module — Synth — that gives you control over Haiku's built-in synth library ('fluidsynth') to play instrument sounds directly, with no need for external synth hardware. It provides much more flexibility than, say, MidiPlayer, allowing you to choose your own soundfonts — several if you wish — and set all the Reverb and Chorus parameters that fluidsynth provides. The old BeOS-era 'WvrSynth' has been removed as superfluous.

Both the heavily-used Program and Controller modules have been extended to permit custom lists for their control panels, making things much more convenient for your own particular soundfonts, or even external sound sources. One other module is new here, though it really only has a specialized use or two — Polyphony. It restricts the number of notes that can sound at once, which can be necessary for some software synthesis schemes.

Release 2.8 — rebuild (Oct 2009, released August 2010)

This was an interim upgrade so that the BeOS version would at least run on Haiku as well. The release 2.8 modules described below were rebuilt to remove dependencies on BeOS R4 conventions, but the code was not changed in any way. It runs on BeOS exactly like the previous release, but for Haiku is now superseded by the above.

Release 2.8

This March 2007 release has a few more fixes and enhancements, and two additions to the StreamWeaver set. These latter, 'PipeStream_PTY' and 'GetFile' are actually modifications to PipeStream and ReadFile respectively, but are sufficiently variant that they have been added to the set rather than replacing the others.

'RePlay' now saves System Exclusive sequences properly (a SysEx would corrupt the saved file), and 'DeGlitch' no longer has a crash under certain conditions.

'Transpose' now can be told not to transpose events on channel 10, so that percussion doesn't go weird. 'SysExGen' is now able to calculate checksums for sequences if required. 'Notator' is better at displaying closely spaced notes that previously might overlap, and will use "Melodic Minor" conventions if desired.

Release 2.6 and 2.7

These two January 2007 releases have some fixes of varying importance, one more new module — 'Notator' —, and a largely rewritten 'MidiPlay'. Notator will show you the notes (currently) being played, on a standard musical staff, with accidentals displayed according to the selected key-signature (no timing or sequence representation, just the current notes). MidiPlay now transmits more of the data contained in the midifile, and has more flexible queueing of files to be played. In the way of fixes, FilePanels now understand symbolic links(!).

2.7 fixes some glitches either added or not noticed in 2.6 (!) and has documentation that matches reality a bit better. The ChordSelect module has been improved, as have KeySig and Analyze.

Release 2.5

This August 2006 release has updates to only two components, but one of these is the Weaver program itself (now v3.2), which has had a couple of long-lurking bugs tracked down and fixed (it would sometimes crash on loading a diagram, and an element could 'vanish' sometimes when a move failed).

The other updated module is Replay, which has also had a bug or two fixed — it would crash if a loaded sequence had 'scaled' timing. There are a couple of added features as well. A sequence can now be sent out in 'steps' by successive external triggers, and a new Record mode lets you create sequences suitable for stepped output.

The downloadable archive is the full suite. (Simpler for me than trying to maintain update packages.) Unless you've moved things around in the folders, it should unpack over an already installed Weaver folder.

Release 2.4 (May 2006)

This release added a few new (hopefully) useful modules: These have been updated:

Release 2.3 (February 2006)

This time there is actually a revision to the Weaver main program [the first in six years!]. Weaver 3.1 allows configuration parameters (element settings) to be saved and restored alone, rather than only as part of a full configuration file. This should make it easier to reset diagrams to a desired state after changes.

There are a couple of new (or newly released) modules. MidiLink provides connection to external MIDI producers and consumers via the R5 MidiKit. SysExMon lets you look at the contents of System Exclusive messages (as hex sequences).

RePlay has some enhancements, as does the Controller module. Others have had minor updates and/or bug fixes. Most of the StreamWeaver modules are now included too, for convenience.

Update 2.2

The new modules are mostly concerned with extracting information, such as chord identification and key signature from a MIDI stream; only the Metronome actually generates events. They are: Revised modules: The package also has two updated non-music-specific modules icluded: StreamView and WriteFile, so that extracted textual data can be viewed and saved.

All licensing restrictions introduced in 2.0 have now been removed. All modules are freely useable.


These modules were new in 2.1 and 2.0:


The 2.0 release added recording and playback of MIDI, and provided new-Midikit access to and from other applications. You might use it in conjunction with a sequencer, such as Sequitur, for example, to pre- or post-process a recording.

The previous release to that (1.3) had a considerably upgraded Weaver main program ('v3.0'), with hierarchical diagrams ('Composite Elements'), on-line help, graphical routing and naming of paths, direct replacement of elements in a diagram, and so on. The MusicWeaver modules all had on-line help included as well, a few were been upgraded, and a couple of new ones were added. If you need the details, you can find them here.


The other modules supplied in the suite are:

The following 'Universal' Modules are also included as part of the basic Weaver 3 set.
