CDEXPLOR PACKAGE - The Compact Disc Digital Audio Explorer for OS/2 2.x
by Dave Thomas
---------------------------------------------------------
Requirements
---------------------------------------------------------
This program requires:
- OS/2 2.0 or 2.1 installed with CD ROM support
- MMPM/2 1.0 or 1.1 installed with CD support
- An MMPM/2 supported CD player that allows digital audio disc playback
- See MMPM/2 documentation for supported CD drives
- Output through audio card requires an audio card including:
- IBM M-Audio ACPA
- Pro Audio Spectrum 16
- Soundblaster
- See MMPM/2 documentation for more information on supported audio cards
Installation
---------------------------------------------------------
- Unpack the CDEXPL.ZIP file using "pkunzip cdexpl.zip"
Use
---------------------------------------------------------
Provides a killer user interface to the CD drive attached to your system.
Features
---------------------------------------------------------
- Artist - Disc Title in window caption and minimize icon
(if user entered track information in template-specified format)
- See User Track Information below for more on adding user info.
- Output to
- Headphones
- Any MMPM/2-supported audio card
- Customized play order
- "Track repeat" option allows the same song to continuously play.
"Track repeat" takes precedence over other ordering schemes
- "Disc repeat" option allows uninterrupted play - wrap at end of disc
- "Disc Shuffle" option allows tracks to be played in random order.
- Shuffles differently every time. Very nifty.
- Mute
- Allows you to mute the sound when your neighbor bashes on your door
for blasting your Nirvana disc. Really, just ask my neighbors :)
- Track Information
- User track information associated with disc can be input/saved
The template of user info in the window is an adviseable format.
This template is VERY important if you want support for:
- Artist - Disc Title in the window caption (titlebar and minimize icon)
- Current track name in the status area
Basically the first line of the user track info will end up in the
window caption and subsequent lines will be associated with each track in
sequence.
I've allowed for about 64 chars for a disc title line
plus 64 characters for every track. Hope this is sufficient.
- Here's how you can enter and save your own track info:
1. Type it in the User Track Info window (and drive yourself nuts)
OR (looks longer but is actually much more flexible...)
1. Go to your favorite editor and type in your track info.
Here is an example of the format that works best:
U2 - Achtung Baby
1 Zoo station
2 Even Better than the Real Thing
3 One
(etc., etc.)
I keep a text file with all my stuff in it as a backup of CD Explorer's
profile. You don't NEED a backup, but it is wise if you have lots of
customized track info.
2. Copy the text to the system clipboard
(Many editors allow this: try to select the text and hit Ctrl-Insert)
3. Delete the template of stuff I put in the User Info window
(Select with mouse, then hit the Delete key)
4. Paste the clipboard contents into the User Info window
(With cursor in window, hit Shift-Insert)
5. Save user info
6. From now on, CD Explorer will automagically recognize the disc
- Disc track information displays each track length and start time
- Allows random track selection (double-click or select/push seek button)
- Disc transport function
- Eject
- allows you to change discs.
- Reverse to track start / reverse to previous track
- From inside a track (past 0:00) this will reverse to track start
- From track start (at 0:00) this will reverse to previous track start
- Stop/Pause
- Can manually set position in Position field while stopped
(See "User Cue" below)
- Play
- Forward to next track start
- Disc status area:
- Current track name (if user entered track information in template-format)
- See User Track Information above for more on adding user info.
- Track counter is user-modifyable on the fly via spin-button or direct edit
You can "spin" up or down. You can enter the track you want to go to.
- User Cue: position in track counter with random position setting capability
- This allows you to cue to any location in the track (with second accuracy)
While the disc is playing, this field is a simple position counter,
but when you stop the disc, it becomes the awesome "User Cue" field
Use of "User Cue":
1. Stop the disc (if playing)
2. Enter the desired destination time in track (in mm:ss format) in
the "Position" entry field.
3. Select the cute little "User Cue" button next to the "Position" entry
(I banged my head for a good and *small* button bitmap. I know,
the button doen't exactly scream out it's "user cue" function. )
4. When you resume play, it will resume from the new location
Notice: the cute little "User Cue" button disappears when the disc
is in playback. User Cue is only available when the disc is
stopped.
- Remaining in track countdown
- Partial function option inhales less system resources
- disables button animation
- disables status area and all other function dependant on position notify
- Mini window option requires less screen space to interact with CD
- Save Settings: saves user button selections, window size and position
- Shares device with other programs that use the CD
(open a bunch of CD Explorers at once -- another boffo CD Explorer feature)
Known problem on 486SLC systems with audio card only:
---------------------------------------------------------
- An OS/2 APAR has been opened against MMPM 1.1. Streaming digital data
to the audio card hangs PM. If you encounter this, manually eject the CD
and output to Headphones until OS/2 releases a fix.
