   Patches and Upgrades

ActiveX version (amp3dj.ocx) 3.5.0.10 (June 11, 2008)
Multimedia engine version (AdjMmsEng.dll) 7.5.0.0 (June 18 , 2008)

Fixed builds can be downloaded using the same link, username and password received after purchasing the product: if you should have lost them or if they shouldn't work anymore, please, contact our Technical support.

VERY IMPORTANT: Before proceeding with the installation of updated versions, don't forget to close all of the running applications and to UNINSTALL the existing version: missing this step could prevent the new version to run correctly on your development PC.

Fixed Bugs (since version 3.0)

  • When using more than on instance of the control, the SilencePositionAvailable event will report wrong values.
  • Allocating several instances of the control on several forms that will be opened and closed could cause issues with the visual feedbacks.
  • Changing visual feedback's settings during playback can cause a GPF
  • Calling the CloseSound method immediately after a call to the RequestSoundExportToWav method can cause a GPF: in any case, note that calling the CloseSound method immediately after a call to the RequestSoundExportToWav method is not a correct behaviour and must be avoided.
  • WAV ADPCM format files can cause a GPF during a ReadSoundInfo method's call
  • Changing the width of Spectrum bands through the Spectrum.BandWidth property doesn't produce any visible effect.
  • Starting a recording session, through the Active Sound Recorder control, can cause a discard of the loaded song from memory.
  • If no sound is loaded inside a player, the RemoveTrigger method doesn't remove the given trigger.
  • The manual BPM calculation, performed through a call to the RequestSoundBPM method, will cause a GPF on sounds loaded inside a memory buffer.
  • If more than one instance of the control has been instanced, the Waveform analisys will fail for all of the instances different from the first one.
  • The visual feedbacks suffer a momentary stop of their graphic rendering when one of the players completes playing the loaded sound.
  • Setting the ScaleUnits, SoundsDirectory, ForwRewGranularityType and ForwRewGranularity properties from instances of the control different from the first one will have no effect
  • If both Active DJ Studio and Active Sound Recorder are instanced on the same form the sound card's speakers enumeration could fail.
  • If both Active DJ Studio and Active Sound Recorder are instanced on the same form, the enumeration of players available inside Active DJ Studio could return a wrong value
  • Making a call to the PlaySoundRange method after disabling the automatic fader, through a call to the Fader.Exit method, could result in a GPF.
  • Sounds playback is not always good on AC97 based sound cards.
  • After a call to the Fader.Exit method, on a fader initialized in FADE_SINGLE mode, the SoundDone event is fired over and over again
  • Loading a MP3 file from an Internet URL through the LoadInternetStream method can cause a GPF

  • Memory leaks are generated when instancing the control inside a web page.
  • The control doesn't register correctly on Windows 98 and Windows ME.
  • Positioning through the SeekSound method is not performed correctly on AAC and MP4 sound files.
  • Speakers assignment is not reliable on Windows Vista.

  • The PlaySoundRange method fails if the ScaleUnits property is set to a value different from milliseconds.
  • Speakers assignment is ignored by LoadInternetStream and CreateSoundFromPCMBuffer methods.
  • Methods returning a string could end with spurious characters.
  • An error could be raised when launching two different applications both of them using our control.
  • When a playlist has been performed completely, and no loop has been set, the SoundDone event is raised over and over again.
  • If more than one instance of the control has been created within the same application, the SetPlayerSpeaker, SwapSpeakersRearAndCenter and SwapPlayersSpeakers methods will work only with the first instance.
  • The GetMp3Tag1Field method returns a string with spurious characters.
  • If a LoadSound call fails, a memory leak is generated.
  • The SetRewindOnEOF method doesn't work if no sound is loaded into the player.
  • The LoadSoundSync method won't generate the SoundSyncLoaded event (with error code) if the file to load doesn't exist.
  • During the execution of two playlists with automatic fading, the player reported by the SoundLoaded event will be always the first one.
  • The RequestSoundExportToWav method doesn't work as expected
