source file: mills2.txt Date: Fri, 8 Mar 1996 09:23:22 -0800 Subject: Tuning files From: non12@delta1.deltanet.com (John Chalmers) I have placed binhex 4.0 encoded, compressed ascii files of most of my JiCalc scale archives in the Mills ftp site (in the CCM mac software directory along with JiCalc). JiCalc 4.2 runs under Hypercard 2.0 or above on the Mac. It is shareware and is available both from the Mills ftp site and from the Just Intonation Network. Hypercard readers do not appear to support all of the JiCalc functions, so the HC 2.X application is essential to use these files. The files are JCA.sit.hqx, JCB.sit.hqx, JCC.sit.hqx, TC.sit.hqx and a short non-binhex encoded readme file, JC/TC_README. The files may be uncompressed and decoded with Expander, Unstuffit or similar programs. JCA and JCB have 400 tunings each and JCC 396. The TC file has 590 entries, most of them from my book, "Divisions of the Tetrachord." The uncompressed and decoded files may be read with any word processor or inserted into a JiCalc stack with the READALL command. I recommend using multiple stacks renamed for each file, at least on the older, slower Mac's. The scales are a mixture of JI, tetrachordal, CPS, tritriadic, tempered, McLarenish, etc. and are not always fully documented as they represent various research interests of mine over the last 8 or 9 years. Because some early versions of JiCalc did not permit one to annotate entries, some entries are rather cryptic. However, I think most will be of interest to at least some of the Tuning List readers. In JiCalc, all scales, equally-tempered, non-octaval, non-Just, non-ET, etc. must be expressed as ratios, either exact or approximate in the case of tempered or other irrational intervals. The approximations are usually within 0.1 cent and were generated by the use of Carter Scholz's algorithm or by Viggo Brun's version of the well-known Euclidean algorithm for approximating irrationals. These four files contain more or less the same tunings as Manuel Op de Coul's SCALA, though in a different format as his program can combine cents with ratios. This resemblance is not entirely accidental; Manuel and I have been exchanging scales by email. His program, however, is more than just a tuning editor. JiCalc may be used to tune a number of popular synthesizers, particularly those made by Yamaha and Ensoniq. Full-keyboard tuning is supported and scales do not have to repeat at the octave (or at all). Adding new scales to JiCalc is easy and the program comes with a very good help file. --John Received: from eartha.mills.edu [144.91.3.20] by vbv40.ezh.nl with SMTP-OpenVMS via TCP/IP; Fri, 8 Mar 1996 19:40 +0100 Received: from by eartha.mills.edu via SMTP (940816.SGI.8.6.9/930416.SGI) for id KAA15097; Fri, 8 Mar 1996 10:39:59 -0800 Date: Fri, 8 Mar 1996 10:39:59 -0800 Message-Id: Errors-To: madole@ella.mills.edu Reply-To: tuning@eartha.mills.edu Originator: tuning@eartha.mills.edu Sender: tuning@eartha.mills.edu
