1971-74	For reasons connected with Act One of my Retrospective, I began work on a music-theoretical project which became more important to me than the composition of individual pieces. This project had two objectives which needed to be achieved separately and then integrated: 1. the development of an efficient and robust notation theory. 2. the development of a way of dealing with hierarchically ordered information, independent of symbols and their meanings.

1999	Publication of the first edition of this website. New material included: An open letter to musicologists and A short introduction to krystals Work continues on the Music Toolbox.

2005	February: Consultancy agreement with Hartmut Ring, the author of the capella music notation editor and its public CapXML file format. First windows computer (an Acer Laptop). This was bought for me by Hartmut Ring and Hans-Ulrich Werner of capella software. Beginning to program again. Port to Windows of my existing Krystals software in C. Learning Python (which is used to write capella's plugins). September: learning C# and the .NET framework. Ceased active participation in all virtual projects in order to concentrate on the capella consultancy and Moritz. Shut down the first edition of this website. I want to tie all the above threads quietly together. Study 1 (a score written in CapXML using Python).
2006	Work continues on Moritz.
2007	February: Capella Consultancy agreement comes to an end. April: Moved to my current address in Cologne. Work continues on Moritz. December: Karlheinz Stockhausen dies.

2009	April: Act Two becomes the new edition of this website. May: First 64bit computer (MUSIC STORE Audio PC4 Core i7-940 Silentmaxx) Work continues on Moritz.
2010	July: Study 2a (a score using an early version of Moritz’ new algorithmic composition module — written in C#). An algorithmic composition module is being developed for Moritz (work continues). October: Study 2b. November: Moritz begins to learn non-standard music notation.
2011	February: Scores Study 2b2 and Study 2b3 completed.
2012	Spring: Moritz v1 archived. Moritz v2 begins — without the patch editor and without standard music notation. I begin to learn Javascript. Moving towards making Moritz open-source. July: Uploaded the Study 2c scores and Study 3 Sketch October: Uploaded the first web version of the Assistant Performer. This does not yet take MIDI input, but has advanced control functions which can be used when playing SVG-MIDI files. The source code for this project (HTML5 and Javascript) has been made public (open-source) at GitHub. December: Updated the Web AssistantPerformer. It can now use MIDI Input and be used as a proper assistant.
2013	March/April: Uploaded major updates of the Web AssistantPerformer.
