Wave editor
Open a wave file always
by selecting New wave editor instance in MIDI Locator's
main menu
Open wave editor window
Play, sound quality
If you have opened a wave file and you press play inside the wave
editor, the file will be sent to your default Direct-X wave output
device. Your wave file is internally recalculated to 44.1 kHz
and send to Direct Sound as 44.1 kHz stream, nevermind which frequency
your file uses. So it is possible to play a 96 kHz file, even
if your sound driver only supports 44.1 kHz.
On the other hand, a recalculation is only done by fast raw calculation,
there will be no quality interpolation when playing 96 kHz wave
files.
That was the the point of wave output. What about the internal
calculations used by edit functions ?
Inside the wave editor's edit function MIDI Locator will
always use the original material and internal calculate (mix,
paste, volume change etc.) with its frequency. That is, interpolation
is not used there, as long as not two pieces wave of different
frequency have to be merged. This happens if stretching or compressing
the copy buffer, and putting it back on the original wave. That
is a point where you can decide, if MIDI Locator should
use a high quality interpolation algorythm - or not. Because it
can be very time consuming. If you want it, please set 'Interpolation'
to 'on' in MIDI Locator's settings.
From edit functions now back to the realtime play : An original
44.1 kHz wave file will always be played in it's original qualtity,
because the output device will be set to 44.1 kHz, no recalculation
is necessary. But if you want the best play back result for a
96 kHz file, first open the wave, paste it to the copy buffer.
Then create a new wave file with 44.1 kHz with the same length,
and paste the copy buffer into it with 'Interpolation' parameter
set to on (but it will need a while to recalculate, you will see).
Single document window
If you want to open a second wave file while the first one is
still opened, please just create again a new instance of the wave
editor with "New wave editor instance".
A wave editor instance is a single document window. If you open
another wave by pressing the open button in one instance,
the preveous opened file will be closed.
Think of a wave editor instance
as a small wave editor application (with own toolbar buttons)
inside MIDI Locator. You can open 10 wave editor instances
if you want, but one and the same file can't be opened in another
instance at the same time.
MIDI Locator tries to safe your time as good as it can,
so all wave changing functions (volume, cut, paste...) are done
direct to your opened wave file. This keeps a frustrating
saving time at the end of your work out of your life, and all
changes could be undone by the undo function,
immediatelly. Inside the wave editor you'll be never asked for
"save file ..." like as working with the MIDI
functions, because the wave editor has saved your file !
The wave editor works with a separate, internal clipboard (copy
buffer). So it is possible to hold MIDI data and wave data in
it at the same time.
Fast view image
Visualisation of fast
view image file
MIDI Locator creates a fast view image for a preveous
not opened wave file. The creation can cost a little time if you
open a large wave file the first time inside MIDI Locator's
wave editor. The image is stored as separate data inside your
wave file.
Selection
When you press the left mouse button and move the mouse, you define
a selected area (inverse shown in the window). All further wave
changing functions are limited to the width of this selection.

file partially covered by a selection
Even if you press play, playback starts at the beginning of your
selection and ends at it's end. If you want to release
your selection (for example if you want to start playback from
the left screen side), just click the left mouse button at any
position inside the wave editor window and release it at the SAME
position - the selection disappears.
Use the +1 and -1 buttons to
expand or minimize your selection on it's right edge pixel
by pixel. This is usual used to hear a kick drum starting
and audible finding a beat in a peace of music.
The +1 and -1 button act on your last selected cue point or loop
point (see flags).
Only if no such flag is selected, the +1 and -1 button refer to
the selection end in the explained way.
Deselect a flag by pressing ESC or by touching the end of the
selection.
Zoom
If you want to zoom the wave file, just create a selection and
press the zoom plus button. Zoom back with the zoom minus button.
If you double klick the zoom minus button, you can get the whole
view of your wave in a very fast way.
Cut/Copy/Paste CTRL-X, CTRL-C,
CTRL-V
Cut your selection by
pressing the Cut button or CTRL-X,
copy it with Copy button
or CTRL-C, paste it with the Paste
button
or CTRL-V. The Cut function removes your
selection and its contens from your wave file and fills the copy
buffer (clipboard). Please read seperate page about Wave
editor's clipboard.
Delete DEL
If you want the same functionallity without filling the copy buffer,
press the DEL key.

Tempo calculation
MIDI Locator helps you in calculating the tempo
of sampled music : Create a selection which exactly covers 10
whole measure (use the zoom function, cue points, the +1/-1 buttons
and PLAY for exact adjustment).
You can now read the calculated tempo in BPM in the upper right
dialog part.
Gain
The gain volume doesn't have
direct affect to your wave file, it's just saved as a parameter
in wave file.
Use this slider to boost or lower volume of your wave without
changing your original wave. The gain change will be used in all
modules inside MIDI Locator where the wave will be outputted.
The idea is that samples which are soft should not be powerd up
with a destructive wave data changing "volume change".
You should just set a positive gain for them. Because if you later
command MIDI Locator to play that file (maybe by a Note
On event) with a low volume, MIDI Locator would lower the
volume of your up pumped wave file, unnessecarily.
The use of gain keeps the original dynamic of your wave as good
as possible.
Key
Set the original key of your wave file here, if you want to use
it in MIDI Locator's Virtual Sample Player.
Copy buffer properties
They specifiy how the wave editor treats the copy buffer. The
settings are only available if you have previously copied a piece
of your wave file into the copy buffer and have pressed the paste
button one time, so that the "ghost" is visible.
Velocity for use
in Virtual Sample Player
You can set a volume range if you will later user this wave file
in the Virtual Sample Player. Only if a Note On has a volume
value inside that range, the sample will be played.
Undo
You can undo the last 10 changes in your wave file. Note that
a first selection change after a preveous wave data change consumes
1 undo step.
