Hi, guys!

I'm developnig a simle arcade game with J2ME. I've already done with the engine and now I'm a bit confused with the sound.
I want to loop a midi sample as a background music and I also want to have some sound effects: explosions, shots... etc. The problem is - I can not do that with my Nokia 6230i. I've tried to run my game on the Nokia emulator and everything worked just fine. Is there any limitations on simultaneous midi playback?

Here is the piece of code I use for sound playback:

   private Effects(){
      instance = this;
      try {
         boomSound = Manager.createPlayer(getClass().getResourceAsStream(
               "/effect.mid"), "audio/midi");
         
         laserSound = Manager.createPlayer(getClass().getResourceAsStream(
               "/effect.mid"), "audio/midi");
         
         missileSound = Manager.createPlayer(getClass().getResourceAsStream(
               "/effect.mid"), "audio/midi");
      } catch (Exception e) {
         e.printStackTrace();
      }

   }

.....


   public void playGameBG(){
      if (!MainMenu.settingsMusic)
         return;
      try {
         if (bgSound != null && bgSound.getState() == Player.PREFETCHED)
            bgSound.deallocate();
            bgSound = Manager.createPlayer(getClass().getResourceAsStream("/game.mid"),
                   "audio/midi");
          bgSound.setLoopCount(-1);
          bgSound.start();
      }catch (Exception e) {
         e.printStackTrace();
      }
   }

6230i has some realy nasty sound bugs - makes it an absolute biotch to pass certification.

(if a sound is playing when a call interupt occurs, the sound subsystem completely breaks - and you can no-longer play sound)

Ridiculously, we often have to resort to using the Nokia API for sound on this phone.
