Welcome to TuningFork, another in the short line of programs
developed by the Lestershire Group. TuningFork allows you the
distinction of owning one of the worlds most expensive (and most
accurate) tuning forks -- your computer. Before I tell you more,
though; let me take up a collection.

TuningFork is being distributed as Shareware -- that means you may
try the program before you decide to buy it. That does NOT mean the
software is free or in the public domain. TuningFork is a copyrighted
program, and may not be used, abused or otherwise slandered except as
provided below. The Lestershire Group reserves all rights, etc.
You are granted a limited license to evaluate TuningFork for a
reasonable period of time. If you decide to add this program to your
software "arsenal", please register your program. The cost is a modest
$10.00, and entitles you to gripe at me for all the features I callously
omitted from this release. You are also granted license to distribute a
copy of this program to as many people as humanly possible. Please feel
free to pass it around the conservatory, or user group meeting, etc.
Also, please upload this program as soon as possible to all BBS systems
that have not yet removed your access. Two small limitations go with
this license: You may not alter the program in any way, and you must
include this erudite documentation file. You may NOT add any of your
own files to the archive -- in particular, you may not place your BBS ad
in the distribution archive.

ATTENTION: This program carries no warranties, expressed or
implied. I make no guarantee that the program will work with your
computer. For all I know, it may shatter every capacitor on your
motherboard. It may lock up your system, make your cat sterile, or
cause cancer in rats. You use this program at your own risk. Use of
this program constitutes your agreement to hold the Lestershire Group
harmless for all overt or covert disasters remotely associated with the
use of the program. I will guarantee that tomorrow will follow today.
If I am wrong, SUE ME! Otherwise, you are on your own.

TuningFork is really very simple in concept: it uses your computer
speaker to generate a very exact tone, suitable for tuning your autoharp
(or whatever instrument you happen to prefer). The program will sound
any note you happen to want, to the limits of your PC speaker. The
frequency range of most PC speakers is from a low of about 20 to a high
in excess of 12,000. WARNING: Do not try one of the really high
frequencies around a particularly sensitive dog!
TuningFork will also allow you to select a frequency for "A". The
standard frequency of A is 440.00 (the default value); however, a number
of ensembles prefer to tune to a slightly higher pitch -- say, 443. You
may set standard A to any frequency at any time. This comes in very
handy when tuning your trumpet to match a piano that can only attain


You may quit the program any time that a note is sounding from your
speaker by hitting either the or key. You can also exit
the program by "entering" nothing when you are prompted to enter a note.
Instead of entering a note, just smack the key, and you will be
returned to DOS. (I put this paragraph up here at the top because I
*hate* pouring through docs to find the exit instructions)


To run TuningFork, change to the directory that contains the
program, and type TF at the DOS prompt. If you put the file TF.EXE in
your path, you can run TF from anywhere. Whichever. The program starts
up with my logo, and a little paragraph reminding you that I NEED YOUR
MONEY! Tap any key to enter the program proper.
The program will first prompt you to enter a benchmark frequency
for standard "A". If you want to use 440 for "A", simply tap the
key. Otherwise, enter a frequency. You may specify up to two
decimal points if you are *really* interested in accuracy.
Once you are past the calibration step, you will be prompted to
enter a note. Type in any note in the scale, from C to B. You may type
in natural notes, like "C", "F", etc., or any sharp, such as "G#", "D#"
et.al. If you prefer, you may use the letter "s" in place of the "#"
sign. The program is not case-sensitive, so "G#", "Gs", "gS" and "g#"
are all the same. If you happen to make a typo (like asking for H# or
something), the program will patiently erase your spurious entry and
politely wait for you to get serious. I, on the other hand, get really
ticked off to think that you can play a stinkin' violin, but you cannot
type in a lousy letter even once in a row.


Once you have entered a note, your computer will play that note, as
found in the octave starting from middle C. Please note: the tone
sounded will correspond to the piano note as entered. The program will
not automatically transpose your entry if you happen to play a Bb
trumpet. I am saving that feature for a later release.
Changing the pitch is really very simple. To go up a half step,
tap the up arrow key. Down arrow will take you down a half step. If
you hold down the arrow key, you will go up (or down) the scale until
you either 1) run out of patience, or 2) run out of notes. To change
octaves, tap the [PgUp] key (to go up one octave, naturally) or the
[PgDn] key (I leave description of the resulting action as an exercise
to the student).
To directly change the sounding note, simply begin typing in that
note at any time. For instance, if you are currently playing low G, you
can change your pitch to the B above middle C by typing the letter "B".
As before, tap to complete your specification of the note; the
program will then play your newly selected note in the original (middle)
At any time that a pitch is sounding, you may change the standard A
frequency by tapping the key. The program will halt (but the
current note will continue sounding) while you type in a new frequency.
As before, simply tap to keep the current specification, or type
in a new frequency, and then tap . The sounding note will
immediately adjust upward or downward as appropriate.


You may notice that the speaker emits an annoying clicking sound
every half second or so. Alas, this is unavoidable. The program checks
the keyboard every half second to determine if you have requested a
change of some sort. A shorter duration naturally results in more
clicks per second. A longer duration makes the program much less
responsive to your wishes.
If the clicking noise is interfering with your tuning efforts, you
may "freeze" the computer in one of two ways: either hit the key
on your keyboard, or tap . Tapping the key stops the
computer in its tracks, but does not turn off the speaker. This results
in an uninterrupted tone more conducive to tuning activity. In order to
get the computer operating again, tap the key once.
Another way to generate an uninterrupted tone is to tap the
key. The official purpose of the key is to change the frequency
of A. The unofficial side benefit is that the program will immediately
stop in its tracks to record your new frequency selection. The speaker
is not turned off, so the current tone will merrily continue to sound,
sans the annoying clicks. When you want to resume program action, just
tap the key (thus accepting the current frequency for A).
If you want silence for a moment (the darn telephone rang, for
instance), simply type any letter. The program will assume you are
trying to enter a new note, and will stop to accept your input. Unlike
the key trick mentioned above, the speaker is turned OFF when you
begin typing in a new note. Of course, when you are ready to resume
making your PC sing, you will have to complete the entry of the new
note. If you backspace over the letter you typed, and then hit the
key, the program will assume you want to exit, and will.


If you find this program useful, enjoyable or unbearably silly, I
would like to hear from you. You may contact me by mail (see address
above), or you may leave me electronic mail in the ILink Internationally
BBS network. Try leaving your message for Jim Collinge in either the
ChitChat or ShareWare conferences. Leaving the message in Chocolate or
Politics will make the moderator angry.
Actual product support will be available on the main board of the
Lestershire Country Club BBS at (609) 582-7444. Address your messages
to SYSOP. I look forward to hearing from you.
