Independent designer
and researcher

Retiring, my activities are essentially decided by my personal interests. That are music and exact science. Former colleagues and customers as well as all, who are interested, may appeal to me regarding acoustics in general, or also acoustical borehole measurement (cues are USBA, ABF).

My scientific work concerns a purely geometric theory of gravitation and electromagnetism with vital consequences for all physics.

My musical ambitions concern practical making music, and technical backing. I have made up two packages for all, who take interest in technical aspects of music.
A Linux music package. It provides individual MIDI based musical workplaces, inclusive of notesetting.
This is completed with a Linux based
organ package, see also text.
With a MIDI clavier block, one obtains a full house organ.

The artistic component, i.e. the actual sound creation, consists in soundfonts. That are sound samples, which are controlled and played with the software in above mentioned packages via MIDI. These are freely available, however, I reserve the right of commercial use for myself as author.
org_harp.sf2 (1.4 MB) * MIDI samples
Alive harpsichord and clavichord sounds from "natural" samples. Supplemented by additional instruments and synthetic organ sounds.
Two special organ soundfont banks:
alive2og.sf2 (1.3 MB), with MIDI demos.
The test version of a model organ, compatible with all soundfont drivers:
organ2MB.sf2 (1.4 MB), with its disposition.
Combines the noble and alive sound of best baroque organs with the possibilities of the computer technology. With "natural" samples.
A Wave sound sample (3.7 MB).
Soundfonts and wave data have been packed with `rar'.

Greatest artistic demands are met by three organ soundfont banks with carefully selected and attuned samples from historic organs. Also these are compatible with all soundfont drivers.
A universal organ (5.3 MB),
which fits in 8 MB dRAM. Includes everything. With a harpsichord section and subharmonic structures.
A Renaissance organ (1.3 MB),
which orientates itself at the transition from Renaissance to Baroque. It fits in 2 MB dRAM. Historically attuned, and with historic key allocation. The same in standard implementation. Exceptionally sound-beautiful.
A Baroque organ (2.6 MB),
which fits in 4 MB dRAM. It is a Baroque extension of the Renaissance organ, and backward-compatible with it.
Scherer organ (1.1 MB).
Unique sounds.

All organ soundfont banks have been designed for additive mixture. The programs of the organ package ensure it. A few test mixtures have been added.

DOS corner.
Best quality of reproduction is ensured with the already obsolete Creative AWE32/64 (with ISA interface). Therefore, I enclose a DOS program for hard disk recording. It uses the SB16 standard, and avoids any unsteadiness from multi-tasking operating systems.
Test programs for masterkeyboard and MIDI interface have been added.
