+,ABOUT PSTUNER (1:3) - SHAREWARE NOTIFICATION
+B     PSTuner came about as I was getting more and more into my 3a,O
+Btrying to grok OPL, and playing more guitar (more about music in aO
+Cminute). It occured to me that while I didn't always carry a tuner,O
+"I almost always had my 3a with me.O
+D     I wrote PSTuner to exploit the digital sampling and programmingO
+Cfeatures of the 3a, and because it was something I could use. It isO
+Dmy hope that you, too, will find it useful. If you DO continue usingO
PSTuner, it is shareware...O

OVERVIEW
+A     PSTuner is a Psion 3a 'strobetuner' that determines pitch byO
+;grabbing quarter-second samples and counting cycles/second,O
+@using a couple of creative algorithms tailored to the Psion 3a'sO
sampling environment.O
+F     It is extremely accurate (at a cost of some speed) and will yieldO
+@best results when fed clean, consistent notes (a note struck tooO
+Dhard will ring sharp before settling in). Or, you can use harmonics.O
+	HARMONICS
+A     Every note consists of a fundamental, and harmonic overtonesO
+E(thirds, fifths, octaves, etc.). These 'harmonics' can be isolated onO
+Fa guitar (or bass) by partially muting a string at the twelfth, fifth,O
+Cor seventh frets, as you pluck the string. This dampens the grosserO
+Fvibrations of the string, letting the higher-pitched components of theO
+Bnote (harmonics) ring through. 12th and 5th fret harmonics produceO
+Chigher octaves of the fundamental; 7th fret harmonics yield fifths.O
THE DRIVER - Sys$samp.ldd
+C     PSTuner makes use of a driver provided by Psion. The docs thatO
+Acome with the driver include the following disclaimers, which areO
+.not as dire as they might sound at first read:O
+B    ''Psion will not be held responsible for any loss of data as aO
+Bresult of use of Sys$samp.ldd, which is still to some extent in anO
+@experimental phase. It has not been exhaustively tested, and canO
+Fnot be relied upon, i.e., not to reset your 3a occasionally. It is notO
an official Psion product.''O
FILES
+APSTuner requires three files, which must be kept in the followingO
+-locations on the (same) drive of your choice:O
        \APP\PSTuner.opaO
        \OPD\Tuner.picO
+3        \Sys$samp.ldd   (must be at the root level)O
+EIn addition, Psion has authorized distribution of Sys$samp.ldd on theO
+Fcondition that the docs and sample files (originally uploaded by PsionO
+Aas TSMP10.ZIP) are kept together. They are included with PSTuner.O
STUFF
+H     The 'Esc' key will get you out of most PSTuner screens. Help is notO
+Davailable while in LISTEN mode. If you don't back up your 3a, eitherO
+Ato a RAM card or another CPU, please re-read the help file calledO
+:PSTUNER HELP: THE DRIVER, and give backups some thought...O
+,unless, of course, you have nothing to lose.O
+A     I am not responsible for out-of-tune performances or loss ofO
+@data resulting from use or misuse of PSTuner or the Sys$samp.lddO
+?driver. Oh, and don't forget that PSTuner is shareware. Thanks!O
