MIDI Sequencing for Haiku


Sequitur is a BeOS/Haiku-native MIDI sequencer with a MIDI processing add-on architecture. It allows you to record, compose, store, and play back music from your computer. Sequitur is designed for people who like to tinker with their music. It facilitates rapid, dynamic, and radical processing of your performance.

Features:

  • An add-on architecture for processing MIDI and performing MIDI effects. Change a track's velocity, apply echo, add chorus, change its key signature, etc.
  • MIDI processing is integrated with editing: Paint with echo effects, paint chords in key, etc.
  • Easily rearrange songs with familiar phrase operations.
  • Customize your interface with skinning.
  • Achieve special effects with tool properties: Turn on gradual delete and slowly rub out MIDI events.
  • Full support of Haiku's advanced MIDI services: All Midi2-compatible software is automatically available.
  • Record, edit, and playback note, program change, control change, and pitch bend MIDI data.
  • Read and write standard MIDI files.

This version (2.1.2) of the source compiles and runs under Haiku, without any so-far-detected limitations. It is essentially identical in behaviour to the last 2.1 BeOS version, except that the FilePanels are a bit smarter (they filter to show only MIDI files, and preserve the working directory). It now saves files with MimeType 'audio/midi', but recognizes 'audio/x-midi' and 'audio/mid' as well.

The "devkit" folder in the BeOS original has been omitted from the user package because it has not yet been checked that it matches the current source [it almost certainly doesn't]. As the complete source is now freely available it is probably redundant anyway.

Downloads:

Sequitur 2.1.2 (3.73MB zip)
Complete MIDI Sequencing for Haiku. Download and unpack anywhere convenient for use.
Sequitur 2.1.2 hpkg (4.32MB hpkg)
Working recompiled version for current Haiku in Haiku-Package form. Download and drag to /boot/system/packages or ~/config/packages.
Original Sequitur 2.1.2 hpkg (3.61MB hpkg)
This is the original hpkg which no longer runs in recent updates of the OS. If you have an older installation it might work where the newer version won't.
Source for building the above version (2.89MB zip)
This source is complete for building Sequitur 2.1.2, but has been trimmed of about 5MB of code that is unused here. The complete original source from ARP, now patched to match this, is available at HaikuArchives.
SoundFonts
It seems that the TimGM Sounfont available from HaikuDepot is still not the fixed one!! Three of the instruments (admittedly not all that popular ones) are unusable in certain key ranges: "Harmonica" (23), "Bandoneon" (or "Tango Accordion" 24), and "Whistle" (79). I fixed the font several years ago, and passed it back to the author, but it doesn't seem to get propagated... If you want to experience the worst two instruments (Bandoneon and Whistle, here's a brief demo file! The really fixed version is here as a Zip file (5.31MB) or an hpkg (5.31MB)

There are may other soundfonts to be found on the web. One I find I use most is "General User" (29.83MB — get FluidSynth-version 1.44).
