Software (Open source and downloadable)

All software mentioned here written before 1997 is in Microsoft Basic QBX - PDS V7.1 for IBM-type PC's. All more recent programs are either translated or originally written in Power Basic (mostly PBWIN 10.04) and/or in C++. All this code compiles to real 32/64-bit code and runs under all Windows versions. None of this software is 'user friendly': not too much graphics, almost no idiotographs… A programmers delight. All compiled executables and DLL's can be found in a separate directory on this website. Source code is available on the site as well.

HarmLib: a library for generalized musical harmony

Instructions and links for downloading and use can be found in: Users Guide in HTMLThe new version works only compiled under PowerBasic Windows Compiler 10.04. Previous platforms (Microsoft Basic) are no longer supported. The library is now available as a a set of DLL files - and is now fully merged with and integrated into our GMT multitasking composition software. There also is a web page with FAQs about GMT

We are still looking for people willing to help us in further developing granular code sections, debugging, porting more code to DLL format, more elaborate support for real-time sound synthesis, graphics, device drivers, audio streaming, etc... So far we welcome and welcomed contributions from Kristof Lauwers, Philippe Druez, Lara Van Wynsberghe and Johannes Taelman.

GMT: a general purpose multitasking framework for use under PowerBasic Windows Compiler V10.04 and the Win32Api

<GMT>: multitasking programming language for real time algorithmic music composition in Basic [PowerBasic Windows compiler required]. This software package for programming composers has full support for musical syntax: extended counterpoint and harmony, real temporal autonomy of musical voices and processes, real time input and output devices... It is a 32-bit PC programming environment with full access to all Win32Api functions (including real time audio!) from within racing fast compiled Basic.

Users Manual for <GMT>Instructions for downloading are contained in this document. The files are in a single subdirectory with the URL: on the webserver. The version available now is for use under the Power Basic Compiler for Windows. The software fully supports the Win32Api, including callback functions and codepointers, objects, DLL calls etc.... Feel free to download the source code.. We advise you to install them under C:\b\pb\gmt\ on your PC. This makes sure you do not skip any essential files and that all libraries are in the directories where the program expects them to be....
