## 2. System requirement

OS: Mac OS X 10.7 (Lion), 10.8 (Mountain Lion), 10.9 (Mavericks), 10.10(Yosemite), 10.11(El Capitan), macOS 10.12(Sierra)
CPU: intel CPU (MIDITrail has no support for PowerPC)

It is recommended that your Mac has high performance graphics for smooth animation.
If the MIDI datasets contains a lot of notes, the software needs more performance graphics.
As long as the performance of your Mac allows, please enjoy MIDITrail with large window.

## 3. How to install and execute

### (1) How to install

Extract ZIP file, and execute "MIDITrail".

### (2) First setup

At first, you must setup the MIDI OUT port.
Select "MIDI OUT..." from "Option" menu, then "MIDI OUT configuration" dialog will appear. At least, you must select the MIDI OUT device of "Port A". Ordinary MIDI datasets is sent to "Port A".

If you want to play the MIDI datasets which uses multiple ports, you must select the MIDI OUT device of port B, C, and so on.
NOTICE: To play the MIDI datasets which uses multiple ports, it is necessary to prepare MIDI interface and MIDI module which supports multiple ports.

### (3) How to uninstall

Delete "MIDITrail" application.

### (4) How to open Recomposer data files

Recomposer is an old popular MIDI sequence software in Japan.
MIDITrail for Windows can open Recomposer data files (*.rcp *.r36 *.g36) using RCPCV.DLL (Recomposer File Converter) which Mr. Fummy releases. However, RCPCV.DLL did not work on macOS. So MIDITrail for macOS does not suport Recomposer files.

## 4. Usage

### (1) How to open a MIDI file

Select "Open..." from "File" menu, the Open File dialog will appear. And choose a Standard MIDI File (*.mid).
Or you can drag and drop a MIDI file into the window of MIDITrail.

### (2) How to play/pause/resume/stop

Push the following keys, or use "Playback" menu.

Key | Action
--- | ---
`SPACE` | Play / Pause / Resume
`ESC` | Stop
`1` `2` | Skip Back / Skip Forward
`4` `5` | Playback Speed Down / Up
`F2` | Double speed playback

### (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`.

Key | Action
--- | ---
`W` `S` | It moves forward and backward.
`A` `D` | It moves left and right.
`Q` `E` | It goes up and down.
`Z` `C` | It moves along the direction of MIDI datasets. (In PinoRollRain, it moves along the piano keyboard.)
`SHIFT` + [`W` `S`] `SHIFT` + [`A` `D`] `SHIFT` + [`Q` `E`] `SHIFT` + [`Z` `C`] | When you push move key with `SHIFT` key, you can move at high speed.
`CTRL` + [`W` `S`] `CTRL` + [`A` `D`] | 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.

Key | Action
--- | ---
`↑``↓` | It moves forward and backward.
`←``→` | It moves left and right.
`PgUp` `PgDn` | It goes up and down.
`,``.` | It moves along the direction of MIDI datasets. (In PinoRollRain, it moves along the piano keyboard.)
`SHIFT` + [`↑``↓`] `SHIFT` + [`←``→`] `SHIFT` + [`PgUp` `PgDn`] `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 Mac.
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

Counter | Details
--- | ---
FPS | Frame Per Second.
TITLE | Title of music.
TIME | Elapsed time.
BPM | Tempo (Beats Per Minute).
BEAT | Time signature.
BAR | Number of bars.
NOTES | Number of notes.
SPEED | Playback 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 in Terminal, you can use following arguments.

    open ./MIDITrail.app --args [-p] [-q] [path/to/file]

argument | detail
--- | ---
-p | Play MIDI file after startup of MIDITrail. If you did not specify "path/to/file", this option will be ignored.
-q | End MIDITrail after end of playback. If option "-p" was not specified, this option will be ignored.
path/to/file | MIDI file path. When you specify a path including a space character, please use escape code. ex."file\ name.mid"

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 Mac 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 Mac 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. 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 Mac, please try to open MIDI file which contains few notes. If the animation does not improve, please use Mac which has high performance graphics.

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

Move your viewpoint to your favorite position, and select "Save viewpoint" from "View" menu. Then your current viewpoint will be saved.
Or you can select "Auto save viewpoint" of "View" menu.

### (3) Q. I want to customize the window size and position.

You can customize the window size and position. Please open following file by Property List Editor.
Property List Editor is a utility application of Xcode.
If you want to customize the window size, edit "Width" and "Height".
If you want to customize the window position, add "WindowPosition", "X" and "Y".

    ~/Library/Preferences/jp.sourceforge.users.yknk.MIDITrail.plist

    View
        WindowSize
            Height=600 (Type:String)
            Width=800 (Type:String)
        WindowPosition
            X=100 (Type:String)
            Y=200 (Type:String)

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

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

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

You can change size of the ripple by editing configration 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.
    http://ci.nii.ac.jp/naid/110002935789

    http://ci.nii.ac.jp/naid/110002712125

You can get some related papers by searching web.
comp-i seems to a software for Windows, using World-ToolKit.
It is not opened to the public. I want to see it someday...

#### MIDIJam / Author: Scott Haag / 2005?-2007

"MIDIJam" is a MIDI player for Windows using OpenGL.
This software displays the 3D musical instruments which are performing in real time. MIDIJam supports 92 different instruments in the latest version.
