Multiplay Engine V1.12

This Tool is using Windows MCI (Media Control Interface). This interface is supported in Windows 9X, Windows NT and Windows 2000.

My intention was to make a multiple player that can be used as jingle machine. Some of my personal requirements where:

  1. Fast restart (jingles)
  2. Easy to use
  3. OS Windows 9X, NT and 2000
  4. Saving configuration (loaded files, selected devices)
  5. Playing Sequences with overlap (jingle, filler, jingle, song)
  6. Minimum System requirement 200MHz
  7. MP3 Codecs installed (playing .MP3 files)
  8. Multiple Output control (2 soundcards)

The latest version is able to work with 2 sound cards. This requirement is added for DJ users. For each player you can select separate sound cards.

In the chapter SoundBlaster Live! (SB-Live!) you can read how to install 2 SB-Live! Sound cards.

This version of Multiplay has no volume control. There is no fading possible when playing a sequence.

The next version of Multiplay will have a playing list and sequence editor.

Maybe I will use Direct-X for the next version. Using Direct-X will ask more system performance.

The Multiplay engine is able to play MP3 files when you have installed a MP3 Codec on your PC. When you have installed a Windows Media Player on your PC you already have the MP3 Codec. Use the "Microsoft Sound Mapper" as Output Device. This mapper will select correct Codec according to the file to be played.

Using 2 SoundBlaster Sound cards

It depend on you requirements.

You can choose the following configurations:

  1. Install a SB PCI128 together with a SB Live! Card. The PCI128 can play files successive without overlap. The SB Live! Is able to play multiple files.
  2. Install (note 1) 2 SB Live cards. Both sound cards can play files with overlap.

Note 1: It is not possible to install 2 SB Live! Sound cards in 1 PC using the regular SB Live drivers. After a lot of browsing on the net I found a driver that can be used for the 2nd SB Live Card.

You can download the APS driver here http://come.to/sblive

Load

Use this button to load a file. When the files can not be played using the selected output device you will be notified. It is possible to select the correct Output device after selecting the file.

With the standard Windows file browser you can select the .WAV or .MP3 file you want to load. The directory from where you selected the file will be memorised for the next file select.

This will clear the complete loaded player settings.

This will Pause/Resume when the player is in Pause or Playing mode.

Progress Bar

This Bar will show the actual position of the player. You can also use this bar to set the starting position where the player should start playing the loaded file.

Actual Playing time

This represents the actual playing position

Delta time

The Delta time will be used by the next player in a sequence. For instance:

Player 1 Delta time is 500 (ms) and the sequence is Player 1 =1 and Player 2 =2. When player 1 actual time reaches its total time Ė 500ms, Player 2 will start to play.

Sequence A (Player)

You can make 2 separate sequences. Both are identical. You can select only loaded players only once. The sequence number will increase when a player is selected.

When a Sequence is started, all files will be played according to the sequence. When you configuration allows overlap you can also use the Delta Time.

Sequence B (Player)

See Sequence A.

Output Device

When you configuration allows multiple Sound cards you can select an Output device for each player. You need to know that only .WAV Files can directly be played by a sound card. If you want to play a .MP3 file you should select the "Microsoft Sound Mapper" as Output Device. This Output device will be available when you have installed the MP3 Codec for the Windows Media Player.

(I often use .WAV jingle or filler files and .MP3 song files).
