new JI Calc version

Version 4.4 of JI Calc is now available at:
ftp://mills.edu/ccm/tuning/software/mac/jicalc44.sea.hqx

JI Calc is a Hypercard stack for creating and archiving musical
tunings, especially in just intonation. It provides MIDI transfer
of tuning data to instruments that support alternative tunings,
specifically Yamaha DX-, TX-, and SY- units, the Emu Proteus series,
the Ensoniq EPS series, and the MIDI Tuning Spec. It also plays
up to 8 simultaneous tones using Macintosh local sound.

This stack requires Hypercard 2.0 or higher. Sound on PowerMacs
requires QuickTime 2.0 or higher and QuickTime Musical Instruments.

JI Calc 4.4 changes (1/1/97)
New features:
- Single version for PowerMacs and 680x0s. Checks for QuickTime
and Sound Manager; uses them if present, falls back to older
Sound Driver routines if absent.
- "Lattice" card draws diagrams of tunings.
- String length and fret position calculations for all tunings.
(Thanks to Steve Curtin and John Chalmers.)
- "Help" stack is now identified with JI Calc version number.
- Holding "shift" while clicking Clear clears only the lower part
of each ratio field (results of calculations).
- Ear training feature no longer repeats an interval twice in a row.
- Write and Read functions use standard file dialogs.
Fixes:
- Slower MIDI transfers to avoid problems with some fast PowerMacs
and some synths. Failure to transmit SY-77/99 tuning names fixed.
- Cosmetic changes to interface, incorporating Steve Curtin's "fret pos"
and John Chalmers's "string len" buttons.
- Write and Read bugs fixed.

Too small for sounds. Even though I don't have a web page, I can tell.

Or I suppose you could go telephone quality 8 bit, 8KHz. Bleah...

I hear say that ".AU" files, which I THINK is a file format that Sun
invented, are (losslessly) compressed. Anybody know if helper apps for .AU
files are common, or does pretty much everybody use .WAV in web pages?

Also, I heard from a not-so-authoritative authority that .WAV files
encode ONLY the raw audio data, and do NOT encode sample size, sample rate,
nor number of channels. Anybody know if that's true?

Gary,
My home page and desendants takes considerably more that 1Mb. OK, I
am addicted to 44.1k and 48k stereo sounds, and I have a number of
separate existences.

I currently have 24690275 23.54Mbytes. Of this 24041418 bytes are
sound files (pieces, examples, extracts). The rest are HTML, GIF and
Csound orchestras and scores, and a couple of midi files, and I
suspect some junk.

Sound files are big, and do not compress well. If you were to use a
Csound or MIDI format it might be OK.

Just my experience..... I do get into trouble with local system gurus
at the size of my home page stuff.

ohn

I think so, too. You should probably look into one of the larger
national ISP's, like Webcom. You might also want to consider getting a
domain name, like "garytunes.com," which would enable you to move from
one ISP to another without changing your address. It isn't cheap -- $200
to start, plus $50 every two years to maintain -- but depending on your
purposes, it may be worth the investment.

In addition to site space, you might also want to ask whether the ISP
provides access to the logs of hits to your site. Many of the smaller
ones don't. You'll see how many people a day hit the site, where they're
from, and what pages they visited. These logs can be interesting, and
especially useful if you're promoting an event or a product and want to
check out the effectiveness of your efforts.
