2.0 What’s New
Notable Fixes/Changes in Version 6.0c
  • Fixed a problem that could cause a hang when AAS’s Lounge Lizard 3 is opened and an ACID project is autosaved.
  • Default patch settings are not applied to VSTi soft synths when new tracks are added to a project.
  • Fixed a bug so MP3s with Unicode ID3 tag information no longer cause problems with track names.
  • A drawing issue has been resolved involving drum maps with note data outside their drum map parameters.
  • Fixed a problem that could cause a crash when deleting a bus from a 5.1 surround sound project.
  • Fixed a variety of issues with the Piano Roll Editor caused by dragging files from the Explorer to the ACID timeline.
  • Fixed a bug so that MIDI notes selected using the in inline editing mode will play as displayed while loops are being previewed.
  • Fixed a bug that could cause a crash when rendering to a new track using M-Audio Ozone with a USB connection.
  • In 5.1 surround mode, when a track is routed to a bus, the Surround Master now receives the input monitoring signal.
  • You can now pan tracks that are routed to a bus in stereo and 5.1 surround modes.
  • Fixed a bug so bus levels are preserved after selecting Undo after a bus has been deleted.
  • Fixed a bug that grayed out VSTi sub-busses when the main bus was muted.
  • Fixed a bug that caused audio to stutter or drop out entirely during playback after UAD-1 effects had been added to the project.
  • Fixed a bug so that busses are renamed to their default names when a new project with busses is opened using ACID’s default settings.
  • Various improvements have been made for using ACID as a ReWire device.
  • Fixed various VSTi window sizing issues.
  • Added program change maps for the Korg Karma, Korg Triton rack (system version 1.52), and E-mu Planet Earth.
  • Resolved an issue so audio and MIDI ports remain open when focus is lost and the Preferences pane is open.
  • You can now undo a key change to a MIDI clip.
  • Fixed a bug that could cause ACID to hang when adding keyframes to 5.1 surround projects.
  • Fixed a bug that could cause a crash when you import MIDI files with no note data into your project.
  • Fixed a bug that prevented NI Akoustik Piano, E-mu Emulator X, and Proteus X from loading properly.
  • Resolved two issues regarding undoing MIDI program changes:
    -Undoing a MIDI program change now updates MIDI drum maps with the proper settings.
    -Undoing a MIDI program change now updates MIDI devices or soft synths with the proper settings.
  • Fixed a bug that caused audio glitches at the start of playback in a project with two MIDI tracks routed to a DLS soft synth.
  • Fixed a problem with incorrect event clips caused by removing unused clips and then selecting Undo.
  • Resolved an issue so that you have the option of choosing any audio editor that is configured and not just the first one listed under the Tools menu.
  • Implemented key support for MIDI clips. You can set a MIDI clip's key on the Clip Pool tab of the MIDI Track Properties window. A clip's key affects playback and now notes are drawn in events.
    -When you create a new MIDI clip, the key is set to None.
    -When you open a MIDI file, ACID will set the clip's key based on the MIDI file. If a clip contains key changes, only the first is used.
    -When you open a MIDI file as a project, the ACID project key is updated to match the MIDI file.
    -When a clip's key is set, the project key and key change markers are applied to MIDI clips. MIDI notes in events are drawn as WYSIWYH
     (what you see is what you hear).
  • Implemented various optimizations for memory usage and performance.
  • Improved performance for ASIO drivers that do not notify host applications of buffer-size changes.
  • Improved handling for MIDI track, clip, and event pitch-shifting.
  • Clip names in the Clip Pool window are now updated when clips are saved to new file names.
  • Fixed a bug that prevented arming multiple MIDI tracks for recording.
  • Fixed a bug that could cause a crash when renaming an unnamed clip in the Clip Pool.
  • Fixed a problem that could cause MIDI clips to drop notes during looped playback.
  • An issue has been resolved that prevented FXPansion BFD MIDI files from being added to the ACID timeline.
  • Fixed a bug that could cause a crash when changing the channel of a track routed to a ReWire device.
  • Fixed a bug that could cause a crash when closing Reason when in use by tracks in your ACID project.
  • Fixed a problem that could cause a crash when playing back with certain audio plug-ins (including Antares Filter and Sony Pitch Shift).
  • Fixed a problem that could cause a crash or hang when using the Undo command after MIDI step recording.
  • Fixed a problem that could cause a hang when arming an audio track for recording while recording MIDI data.
  • Fixed a problem that could cause NRPN and RPN MIDI data sent to the DLS soft synth to respond incorrectly to pitch bend or controller data.
  • Fixed a bug that could cause dropouts when routing a multichannel VSTi's outputs to a bus other than the Master bus.
  • Fixed a bug that could cause dropouts or timing irregularities when routing a multichannel VSTi to a non-in-place plug-in (such as Time Stretch, Pitch-Shift without preserving duration, and some Vibrato settings).
  • Fixed a problem that could cause the MIDI Step Record dialog to remain active after canceling step recording.
Notable Fixes/Changes in Version 6.0b
  • In previous releases of ACID 6.0, VSTi plug-ins would stop producing output if the plug-in caused an exception. You can now click the Enable button in the Soft Synth Properties dialog twice to clear the exception to reset the plug-in (if the plug-in allows resetting).
  • You can now load MIDI files that contain only SysEx data. When you load a SysEx-only file, a single track is created, and the SysEx data is displayed as keyframes.
  • A bug has been fixed that caused SysEx data timestamps to be calculated incorrectly during playback.
  • A bug has been fixed that prevented you from opening SMF Type 1 files created in ACID 4 and 5.
  • A problem has been fixed that could cause some VSTi plug-ins to reload the current patch after receiving SysEx data.
  • A bug that could cause a crash after copying envelopes to the clipboard has been fixed.
  • A bug that could cause a crash when using Lynx audio hardware in ASIO mode has been fixed.
  • A bug has been fixed that caused the Join command to incorrectly join unselected events that overlapped selected events.
  • A bug has been fixed that could cause a rendered file to be truncated if you rendered immediately after changing the project tempo.
  • General improvements when adding, removing, or renaming ReWire devices.
Notable Fixes/Changes in Version 6.0a
  • MIDI ports that are used by the Generic Control device driver are no longer reserved exclusively for external control and automation.

    If you have a MIDI controller that includes buttons and knobs, you can use the device as an external control device and as a MIDI input device—for example, you can use the buttons, knobs, and sliders on the device for external control, and still use the keyboard, pitch wheel, and modulation wheel for recording MIDI. MIDI messages that are mapped to external control functions are filtered when you record MIDI.
  • Multiple velocity stems can now be selected and edited with the Selection tool when in inline MIDI editing mode.
  • SMF type 0 files now report their track count correctly.
  • A bug has been fixed that could multichannel MIDI files from ACID 4 or ACID 5 projects to load incorrectly.
  • A bug that prevented rendering to QuickTime format has been fixed.
  • An alternative drawing method has been added for VST instruments. Right-click an instrument on the VST Instruments tab in the Preferences dialog and choose Use alternative drawing method. This alternative method may resolve issues with some VSTis displaying their user interface incorrectly.
  • A bug has been fixed that could cause ACID to crash when pasting an envelope to a MIDI track.
  • A bug that caused ACID 5 projects to load with incorrect MIDI envelope data has been fixed.
  • A bug that prevented aftertouch data from being exported with MIDI has been fixed.
  • A bug has been fixed that could cause ACID to play out of synch with external MIDI devices.
  • The Pitch shift and Speed settings can now be adjusted independently in the Event Properties dialog for one-shot clips.
  • A bug has been fixed that could cause a crash when loading a stereo project when a 5.1 surround project was open.
  • A bug has been fixed that could freeze the Mackie Control Universal when enabling 5.1 surround mode.
  • Various improvements have been made for using ACID as a ReWire synth.
  • A bug has been fixed that could cause audible clicking when playing fade-ins and -outs on looped audio events.
  • Pan envelopes are no longer hidden for busses that are routed to hardware outputs.

3.0 Known Issues
  • Close all applications before you begin installing ACID software.
  • If you have a USB SmartMedia reader device installed on your PC, you may experience problems when you attempt to access your CD drive from ACID software for extracting audio or burning CDs. This is due to an error in the SmartMedia reader driver. Using the Unplug or Eject Hardware Wizard to remove the reader should allow the software to function normally.
  • If you save an ACID project from an earlier version of ACID software in ACID 6.0, it will be unusable in earlier versions of ACID software. Use the Save As dialog to save the project with a new name after editing it in ACID 6.0.
  • If you open an ACID 3.0 project that includes MIDI tracks that have track effects applied, the effects will be discarded.
  • If you open an ACID 3.0 project that includes MIDI tracks that have DLS voice sets applied via Track Properties, the DLS association will be lost. Please create a soft synth control in the Mixer window and apply the appropriate DLS set to the soft synth control. You can then route your track to the soft synth.
  • Timeline offsets are not sent correctly when generating MIDI timecode. Synchronize your projects so measure one starts at 00:00:00.000.
  • 24-bit Windows Media Audio files will always be read as 16-bit files in Windows 2000 (multichannel files are read as 16-bit stereo). This is a limitation of the operating system. You can render 24-bit WMA files, but if you want to read these files as 24-bit audio, copy them to a Windows XP machine.
  • Your network connection needs to be enabled and active to register the Gracenote® Music Recognition Service. If you register without an active network connection, the Gracenote service may appear to register successfully, but you will be prompted to register again when you attempt to use the service.
  • If you use the selection tool to select MIDI notes before clicking the event to select it, changes made on the MIDI Processes and Filters dialog may be applied to notes that are not selected.
  • The .acd-zip file produced from saving a project whose uncompressed media total more than 2 GB in size is likely to be corrupt.
  • When using the Chop to New Clip command on a mono clip, a stereo template may be selected by default. Use the Template drop-down list in the Chop to New dialog to choose an appropriate mono rendering template.
  • When using ACID as a ReWire device in Reason, playback may fall out of synch if you initiate playback using the transport controls on the ACID MIDI Clip Properties window. Stop playback and restart using the main transport controls below the ACID timeline.
  • When ACID is operating in ReWire device mode, automation recording will not create envelopes properly. Existing envelopes will function correctly.
  • When using Reason as a ReWire device in ACID, resetting MIDI ports from Reason may cause ACID to hang or crash.
  • Performance may be decreased (and ACID may become unresponsive) when using ACID as a ReWire mixer and using an external control surface at the same time.
  • ACID may become unstable and crash after rendering when using the ASIO driver for the M-Audio Ozone audio interface. Use the Audio Device tab in the Preferences dialog to switch to the Windows Classic Wave Driver when attempting to render while using this audio interface.
  • If Windows Terminal Services is turned off, ACID will display an error during startup. You can re-enable Terminal Services in the Services Control Panel. Choose Start > Settings > Control Panel > Administrative Tools >Services, and then double-click the Terminal Services entry. In the Terminal Services Properties dialog, set the Startup type drop-down list to Manual or Automatic. Click OK, and then right-click Terminal Services and choose Start from the shortcut menu.
  • ACID Pro 6.0 includes drum, control, and program map template files for a number of MIDI hardware devices. In many cases, we do not have access to this hardware to verify these template files, so they are officially unsupported. However, we encourage you to send updates to so that we may include corrections and support for additional devices in future releases.
