The Dyad System 2025 is a major update and expansion of the earlier version previously available here.
DyadSystem 2025 in the zip file and the rar file are the same. Open with whichever unzip or unrar you have.
Inside are the instructions for setting up the software, and the ArityProlog32Win directory containing the Prolog interpreter with the DyadSystem files (in the bin directory, NUCTRANS.ari, PROLOG.ini, prlg.ari - do NOT alter these!).
There are also the executable INHN programs that are explained in the executable inhn utils directory. The included source code in c for the generation of inharmonic spectra with specific dyads that utilize various algorithms can easily be adapted to other audio synthesis programs.
Explanatory documents and manuals are also included in the archive files. Detailed explanations are in the files "using Dyad System INHNTRVL.txt" and "using Dyad System Prolog.txt." There is also a quick guide to Prolog syntax inside the DyadSystem. Once the DyadSystem is running, you input prlg. and/or prlg2.
