### (3) How to move viewpoint in 3D space

You can move freely in 3D space, and look at MIDI datasets from all directions by operation of keyboard and mouse, like FPS (First Person Shooter) game.
Although there is sense of incongruity in the beginning, it will be very comfortable as experience is gained.

#### Mouse operation

When you click the window, it will become the view control mode by the mouse, and mouse cursor will disappear.
The eye direction synchronizes movement of your mouse.
If you click once again, view control mode will be canceled.
And you can rotate piano roll using mouse wheel.

#### Keyboard operation

Put your index finger on D, middle finger on W, third finger on A.

KeyAction
WSIt moves forward and backward.
QEIt goes up and down.
ZCIt moves along the direction of MIDI datasets.
(In PinoRollRain, it moves along the piano keyboard.)
SHIFT + [WS]
SHIFT + [QE]
SHIFT + [ZC]
When you push move key with SHIFT key, you can move at high speed.
CTRL + [WS]
You can control the eye direction.

#### For a left-handed person

You can also use a cursor key. If you use a mouse with your left hand, this one may be convenience.

KeyAction
It moves forward and backward.
It moves left and right.
PgUpPgDnIt goes up and down.
,.It moves along the direction of MIDI datasets.
(In PinoRollRain, it moves along the piano keyboard.)
SHIFT + []
SHIFT + []
SHIFT + [PgUpPgDn]
SHIFT + [,.]
When you push move key with SHIFT key, you can move at high speed.
CTRL + []
CTRL + []
You can control the eye direction.

### (4) Preservation of the viewpoint

When you do the following operation, your viewpoint returns to the default position.

• When you open a MIDI file.
• When you select stop menu.
• When you select play menu again, after end of playing.

At first, the default position is the viewpoint which looks at MIDI datasets from just beside.
If you want to change the default position, move to your favorite position, and select "Save viewpoint" from "View" menu.
If you want to restore default position which looks at MIDI datasets from just beside, select "Reset viewpoint".

If you want to save view point automatically at the time of application termination or scene change, select "Auto save viewpoint" from "View" menu.

### (5) Change of window size

Select "Window size..." from "View" menu, the Window size configuration dialog will appear.
Select your favorite window size, and push the OK button.
You can not change window size while playing or pausing.

The window size you can select is depends on your PC.
If you want to specify any window size, fill in "Width" "Height".
If you want to apply that size to the view area, check "Apply to the view area".

### (6) Display counters

CounterDetails
FPSFrame Per Second.
TITLETitle of music.
TIMEElapsed time.
BPMTempo (Beats Per Minute).
BEATTime signature.
BARNumber of bars.
NOTESNumber of notes.
SPEEDPlayback speed.

### (7) Structure of 3D piano roll visualization

(a) The structure of "Piano roll 3D" visualization

When MIDITrail open the MIDI datasets uses multiple ports, unused port will be not displayed.
For example, if the MIDI datasets uses port A, C and E, MIDITrail displays port A, C and E side by side, and omits port B and D.

(b) The structure of "Piano Roll Rain" visualization

When MIDITrail open the MIDI datasets uses multiple ports, only piano keyboards of port A will be displayed.
However piano roll bars of all ports will be displayed.

### (8) View mode select

You can select the view mode from "View" menu. You can not change the view mode while playing or pausing.

### (9) Display/Effect switch

You can switch the display/effect at "View" menu.

The piano roll bar will move up/down or right/left with change of pitch bend.
Some MIDI animation works are using pitch bend to shift the piano roll bars without change keys. If the MIDI animation is not displayed correctly, please disable the pitch bend effect to fix the piano roll bars.

### (10) MIDITrail command line interface

If you want to start MIDITrail by command line, you can use following arguments.

MIDITrail.exe [-p] [-q] ["path\to\file"]


argumentdetail
-pPlay MIDI file after startup of MIDITrail.
If you did not specify "path\to\file", this option will be ignored.
-qEnd MIDITrail after end of playback.
If option "-p" was not specified, this option will be ignored.
path\to\fileMIDI file path.
When you specify a path including a space character, please surround with a double quotation mark.

If you drop a MIDI file to the shortcut of MIDITrail, MIDITrail open the file on startup.

### (11) Graphic configuration

Select "Graphic..." from "Option" menu, the graphic configuration dialog will appear.
You can not change graphic configuration while playing or pausing.

Anti-aliasing
If anti-aliasing is enabled, a notch (jaggy) will decrease and a more beautiful picture will be displayed.
However, since processing of anti-aliasing is heavy, performance may be poor when you select a upper level.
If your PC does not support anti-aliasing, it is displayed as "Not supported".

Background image file path
If you want to display the background image, specify the file path of the image.

### (12) MIDI IN Monitor

You can view data sets received from MIDI IN device in realtime.
Select "MIDI IN..." from "Option" menu, then "MIDI IN configuration" dialog will appear.

Select the MIDI IN device for monitoring.
If you check the MIDITHRU, MIDITrail will send data sets received from MIDI IN to MIDI OUT.
When you select "Start Monitoring" from "Playback" menu, MIDI IN monitoring will start.
NOTE: MIDITrail can not record data sets received from MIDI IN.

## 5. Restriction

### (1) Synchronization of MIDI sound and display

If you use the MIDI module which delays sound (such as software sound modules), the MIDI sound and display may not synchronize.

### (2) Performance of graphics

MIDITrail renders all notes of the MIDI file in real time.
Therefore if MIDI file has a large number of notes, the load of rendering becomes high.
In order to enjoy MIDI file which contains tens of thousands of notes comfortably, you have to use PC which has high performance graphics.

### (3) Multiple ports

In specification of SMF (Standard MIDI File), a method to select port is not defined.
However there is the unofficial method (*1) to select port. MIDITrail supports that method, but may be unable to play the MIDI file. It depends on the MIDI file.
(*1) Meta event (FF 21 01 pp) is the command to select port.

### (4) Time format of standard MIDI file

MIDITrail can't open the MIDI file whose delta time represents actual time.

## 6. FAQ

### (1) Q. I got "d3dx9_**.dll was not found" error. I can't start MIDITrail.

Microsoft: DirectX End-User Runtimes (June 2010)

### (2) Q. The animation is not smooth.

Please try to change window size to small, and turn off anti-aliasing. Then the load of rendering becomes low.
Check FPS value in window title. If the FPS value is under 60, the performance of graphics is insufficient.
When MIDI file has a large number of notes, the load of rendering becomes high.
To confirm the performance of your PC, please try to open MIDI file which contains few notes. If the animation does not improve, please use PC which has high performance graphics.

### (3) Q. When I play the music, my viewpoint returns to just beside each time.

Or you can select "Auto save viewpoint" of "View" menu.

### (4) Q. I want to customize the window size.

You can customize the window size. Please open following file by text editor, and edit "Width" and "Height".

Windows 2000 / XP
C:\Documents and Settings\(user name)\Application Data\yknk\MIDITrail\View.ini
Windows Vista / 7 / 8 / 10
C:\Users\(user name)\AppData\Roaming\yknk\MIDITrail\View.ini

[WindowSize]
Width=800
Height=600


### (5) Q. I want to display in full screen.

In present version, MIDITrail can not display in full screen. It may support in the future.

### (6) Q. When I display the menu, the animation stops.

Sorry, it is a specification.

### (7) Q. I got "The application failed to initialize properly." error on Windows 2000. I can't start MIDITrail.

If you are using Windows 2000, you must move "msvc*.dll" files to the folder "MIDITrail.exe" exists from "Microsoft.VC90.CRT" folder, before executing "MIDITrail.exe".

### (8) Q. I got "DirectX API error. / FUNC: DXRenderer::Initialize / INFO: 8876086A" error.

If your PC does not support Direct3D, this error occurs.
Please execute "DirectX Diagnostic Tool"(dxdiag.exe), and select "Display" tab. Is the "Direct3D Acceleration" enabled?
If you can't change "Direct3D Acceleration" to "Enabled", your PC does not support Direct3D. Please use the PC which supports DirectX 9.0c graphics.

### (9) Q. I want to change the ripple more showily.

You can change size of the ripple by editing configuration file.
Please Check "7. Customize - (2) Piano roll".
Change the value of "RippleHeight" and "RippleWidth" larger.

## 9. Appendix

### (1) Story of development

I was enjoying "MIDI ANIMATION" videos which were made by artisans of NICO NICO DOUGA community. (NICO NICO DOUGA is the video hosting service in Japan.) Then I got the image that I am walking through the trail, there are many floating piano roll bars. In order to actualize this image, I started development of MIDITrail.
However, after a few days, I found the demo video of "MIDIPlayer" which supports 3D piano roll at NICO NICO DOUGA. It dejected me a little, but I continued development to actualize my image.

### (2) Aapplication software witch supports 3D visualization of MIDI datasets

In Google and Youtube, you can find many videos which converted MIDI datasets into 3D CG animation. But there is few applications which synchronize MIDI sound and display with 3D visualization.
The applications I found are shown below.

#### 3D MiDi / Author: Marc Cardle / 1998-2000

"3D MiDi" is a MIDI player for Windows using OpenGL.
Cubes and balls move about with MIDI sound. Now, it has been hard to get the software.

MADO NO MORI: "3D MiDi" Alpha 0.1, synchronizes MIDI sound and 3D animation.
http://www.forest.impress.co.jp/article/1999/11/18/threedmidi.html


#### comp-i (Comprehensible MIDI Player-Interactive) / Author: Reiko Miyazaki, Issei Fujishiro, Rumi Hiraga / 2002-2004

"comp-i" is the software which provides 3D visualization of MIDI datasets. Its target is intuitive editing of MIDI datasets.
comp-i has been trying to visualize not only a pitch but various parameters of MIDI datasets.
This software is explained in the paper which tackled 3D visualization of MIDI datasets.

Reiko Miyazaki, Issei Fujishiro: "3D Visualization of MIDI Datasets" July, 2002.
