GuitarTuner V1.1
Written and ©1994 by Christopher Just
INTRODUCTION
Are you a guitar player? Great! Do you have perfect pitch?
Probably not, eh? Then this program's for you. GuitarTuner uses
your Amiga's audio ciruitry to produce the open string notes for a
guitar, giving you a reference for tuning your instrument.
Currently, only standard EADGBe tuning is supported, but that
could easily change in the next version.
DISTRIBUTION
This version of GuitarTuner is copyrighted by the author, but
is freely distributable. If you find this program useful, please
let me know. I'd appreciate a postcard from your locale, just so
I know how far this thing spreads. Or if you have any "rare",
"import", or <ahem> "live" tapes of Pink Floyd, I'd take those
instead :)
See the section on Bug Reports below for address information.
REQUIREMENTS
GuitarTuner doesn't need much, just an Amiga running 2.0 or
higher AmigaOS and a few k of free RAM. Also, it will be a lot
more useful if you have your Amiga's audio outputs connected to
some sort of monitor or speaker ;)
USAGE
At this point, GuitarTuner's windows are pretty much self-
explanatory, so I'll just give a rough guide here.
When GuitarTuner is run, it opens a small window on the
default public screen. On the left side is a set of radio gadgets
which allow you to select which string to produce a tone for (The
keys '1' through '6' can also be used to select a string). On the
right side are a slider to select volume and a check gadget to
turn the audio on and off.
GuitarTuner has the usual "About..." and "Quit" menu items, as
well as an item to open the user preferences window, which
provides additional control over the sound. Right now the only
implemented feature in this window is the Waveform gadget, which
allows you to choose a square, saw, or sine wave pattern.
Experiment with this to see which waveform is easiest for you to
use.
NOTE ON TUNING
Using this program to tune your guitar is much like using a
keyboard or pitch pipes as a reference. Try to match the pitch of
the guitar string to the pitch produced by GuitarTuner. When the
pitch is fairly close, you can use the beats produced by
interference between the two sounds to help you judge. The slower
the beats are, the closer they are in pitch.
For best results, you might want to tune just one string
against the program and tune the rest of the strings relative to
that.
ACKNOWLEDGEMENTS
This program would still have been possible, but would have
taken much longer to write, if it hadn't been for GadToolsBox by
Jan van den Baard and IFF To Source by J. Tyberghein.
Also, for suggestions and bug reports, I'd like to thank
Michael Bauer, Jonathan Gapen (whose request will be implemented
as soon as I get my hands on the new NDK), and Blair Yake
(alternate tunings, including bass tuning, will be included in the
program as soon as I collect enough to make them worthwhile (so
send them in, dudes!). By the way, I've never played bass, so
pardon my terrible ignorance, but just what is bass tuning?
BUGS & BUG REPORTS
If you find any bugs, or have any suggestions for
improvements, please let me know. I am particularly interested in
knowing what sorts of alternate tunings would be most appreciated
in future versions. If you have anything you'ld like to tell me,
send me a note:

RELEASE INFORMATION
1-19-94 1.0
- First release
1-28-94 1.1
- Added keyboard equivalents for gadgets & menus.
- About window image positioning wasn't font sensitive.
- I got my own zip code wrong in the docs :(
- Added saw waveform.
- If for some reason I can't start/stop playing a sound,
it's less likely now that the gadgets will be confused.
Still not impossible though.
