The following appends even the first line as a new line, so the initial empty string becomes an empty line:
Code:
 note=""
 while [ "$not" != "==================================" ]; do
  read not
  note="$note
$not"
 done

You must either branch on a state variable (e.g. $firstrun), or use the "$separator variable" trick as follows:
Code:
 note="" sep=""
 while
  read not &&
  [ "$not" != "==================================" ]
 do
  note="$note$sep$not"
  sep="
"
 done

EDIT: I have changed the oder of read and [ ]. Otherwise one must initialize not="" (or it might have the value from a previous cycle).

NAME

       sfxtest - test utility for the Linux AWE32 driver

SYNOPSIS

       sfxtest [command parameters] ...

DESCRIPTION

       This  manual  page  documents  briefly the sfxtest command.  This manual page was written for the Debian GNU/Linux distribution (but may be
       used by others), because the original program does not have a manual page.

       sfxtest is a program designed for testing that the Linux AWE32 driver has been set up properly, and that the appropriate  patch	files  are
       loaded correctly (using sfxload(1), or gusload(1)).

OPTIONS

       The program takes a series of commands followed by arguments. It accepts the following commands:-

       X      Instructs the program to use channel control mode.

       x channel
	      Changes the channel being operated on to channel

       b bank Changes the bank being used to bank

       p program
	      Changes the program (instrument) being used to program

       n note velocity
	      Sends a noteon command for note note at velocity velocity

       k      Kills a note (sends noteoff).

       K note Kills the note note (used for channel mode).

       r value
	      Sets the pitch sense to value

       w value
	      Sets the putch wheel to value

       t      time Waits for time hundredths of a second.

       c value
	      Sets the panning value to value

       v note velocity
	      Changes the key pressure of note to velocity velocity

       D mode Sets the debug mode of the driver to mode

       C mode Sets the chorus type to mode

       R mode Sets the reverb type to mode

       F parameter value
	      Sends an effect command type parameter , with value value

       I      (Re-)Initializes the AWE32 driver and EMU8000 chip.
