Virtual Composer (VC) is a multiple track graphical music sequencer acting as a QuickTime Musical Instruments (QTMI) interface for the Macintosh, designed for perfect execution of complex polyphonic music using either QTMI's libraries or using custom SoundFont libraries.
VC is intended mainly for performers who want to generate high quality musical executables acting as a musical renderer and sequencer. It is thus predominantly performance-oriented. It is not intended as a musical notator as it contains only a minimal (but sufficient) set of notation capabilities, but can be used as such for simple scores.
Playing is effected via the QTMI synthesizers or via SoundFonts so no MIDI cables or external devices are needed. All upsampling and downsampling is done automatically by QuickTime.
Features
Sophisticated playback using QuickTime or SoundFonts.
The program manual is included with the download in .pdf format and describes the program's more elaborate program functions. You can read it here.
.mp3 Projects
The projects below have been created by exporting VC scores into .aiff's and then encoding them as .mp3's at 128/112 kbits and 44.1 kHz, using QTMI version 4.1.2. Click on an project to download:
Same Prelude (as above) from Lute Suite BWV 996 by J.S.Bach, using a custom Lute-Harpsichord instrument, created by VC with samples extracted and multisampled from a Hungaroton commercial CD, featuring Gergely Sarkozy's own Lute-Harpsichord (128 kbits, 0.8 MBs), (consult section on CD Multisampling for details).
The projects below have been created by exporting VC scores into QuickTime movies, hence are playable on any system that has QuickTime installed, with its version of QuickTime Instruments. Click on a project to download:
Latest version is 3.5.9, build #0 for MacOS 9 and 3.6.1 for MacOS X.
Registration
VC is freeware. Donations through PayPal are appreciated, but are not necessary. You can email the author and he will send you a registration number by email which you can use to activate the saving function of VC(X).
The table above assumes that you are booting into the indicted OS. The VC applications are not guaranteed to work if you are booting into a different OS or if you use the applications in Classic mode emulation from OS X.
Downloading the application and fonts without the supporting files or the opposite (the supporting files without the application and fonts) will be an exercise in futility/frustration. You need to download both, for the corresponding version of your OS.
You may need to install a different QuickTime version depending on your System configuration. For more details, consult the program manual.
The fat application is identical to both 68k/PPC versions and is provided for people who don't know if they are running on a 68k or a PPC machine (it will run on both). If your machine is a PPC, download the PPC version to minimize download times.
