DSP Quattro

Universal Binary support: DSP-Quattro runs natively on Macs based on new Intel processors
the graphic engine has been totally rewritten from scratch to support Quartz graphic libraries of MacOS X
new event dispatching engine for very important improved performances
several GUIs have been re-designed and re-stylished

NOTE:
VST plug-ins are not supported anymore on this version.
Hardware samplers SCSI dumps are not supported on this version.

Requirements
This version requires MacOS X 10.4 or later.
MacOS X 10.5 (Leopard) full support still under investigation.

Improvements :
- now the PlayList window has a title according to the current PlayList file.
- improved AIFF protocol, now DSP-Quattro does not fail to load AIFF files generated by new versions of QuickTime.
- even better code optimization.
- several minor things.

NOTE: Roland S760 SCSI dumps are supported on MacOS 8/9 ONLY.

Bug Fixes :
fixed a problem of audio corruption occurring when playing fast-backward the PlayList on crossfades between tracks
fixed a problem of plug-in latency compensation on the PlayList.
fixed a problem displaying the program preset names for AU plug-ins.
other minor bug fixes

Requirements
- Mac OS 10.2 or newer.

New on this version :
Latency Compensation is now fully supported for real time and off-line AU/VST plug-in processing with the sample precision
Unlimited number of plug-in slots on Effx sends: now this number is configurable by the user.
New Audio CD track ISRC and disc EAN/UPC codes support for audio CD burning (MacOS 10.3 or newer only)
New Audio CD track PQ subcodes support: CopyProhibition and Pre-Emphasis options (MacOS 10.3 or newer only)
ISRC, EAN/UPC, PQ codes are compatible with Jam audio CD Images.
New 'Reset' option on the File popup menu on Effx send windows to clear all the sends with only one command.
Now an empty effect slot on the Effx send can be turned ON/OFF also without any effect, so it can be used as additional gain factor also for processing.

Improvements
SCSI dumps are now fully compatible with the MacOS X IOKit for 10.3 or newer compatibility
The PlayList pauses are burned as reverse counter on audio CD
Better pause values support doing export/import of audio CD images with Jam/Toast
Now the user can choose to dispose the audio file documents when removing the corresponding items from the BatchProcessor.
Now the BatchProcessing table scrolls following the item which is under processing
Very much better BatchProcessing table visual updates during processing
Better file extensions management doing BatchProcessing
Now the PlayList table scrolls following the item which is playing
Now the GenericMarkersToRegions function uses the marker names creating the names of new regions
Now ImportRawData function always force the RAWData file type, also for known audio file formats.
New 'SampleStart Offset' parameter doing ImportRawData
New options in Preferences.
Several other minor improvements

NOTE: Roland S760 SCSI dumps are supported on MacOS 8/9 ONLY.

Bug Fixes
fixed a problem starting cd-rom burning when a blank disc has been inserted before DSP-Quattro asks for it.
fixed a bug in the 'replace with xfade' algorithm interface
fixed a bug ordering new files on the PlayList table, when doing Drag&Drop or importing Jam AudioCD images
now menus are correctly greyed-out when DSP-Quattro displays the AudioCDROM burning dialog.
other minor bug fixes

Requirements
- Mac OS 10.2 or newer.

New on this version :
- now the audio file Info dialog allows the editing of the sample rate to force this value without applying any resampling algorithm
- now also the MIDI parameters are editable into the audio file Info dialog (standard MIDI information is not supported by all audio file formats, anyhow).
- now DSP-Quattro keeps memory of the last mouse click position on the waveform when pausing the audio file player.

Bug Fixes :
- fixed a bug when rendering to file a PlayList having a mono track.

Requirements
- Mac OS 10.2 or newer.

New on this version :
- New PlayList command 'Set All Pauses To...', to set (with options) all the pause values to a certain value with one mouse click only.
- Now the AU plug-in name does not include the vendor name when displaying it on the Effx Send Mixer
- New settable parameter on the preference dialog for the default 'pause' value for newly created PlayList tracks

Bug Fixes :
- Fixed a problem with WAVES, SONY and some others AU plug-ins, appearing greyed out in 2.0

Requirements
- Mac OS 10.2 or newer.

New :

New innovative audio file Doc manager, to work on audio files without the need to rebuild the overviews. Working with the PlayList or BatchProcessor only, do not request any additional waiting time
New Batch Processor, for automated file format conversion, plug-ins and additional processing.
New state-of-art HQ Sample Rate Converter (SRC) algorithm with selectable quality options, applicable also exporting the PlayList, for AudioCD-ROM burning and for BatchProcessing.
New option for using a new graphic engine for the immediate Cut, Copy&Paste, no need to rebuild the overviews in this case.
Immediate undos/redos, always without the need to rebuild the overviews
New Internal VST plug-in database management: no more long waiting times during the application startup
New nested menu interface implementation for the best VST and AU plug-ins management,
Cut, Insert and Replace editing functions now works also on single L&R channels of stereo files.
'Copy Left On Right' and 'Copy Right On Left' channel edit functions.
New export function to save the PlayList Tracklist into a text file for printing.
New preference options

Improvements :
no need to rebuild overviews after saving a file
the computation to build the overviews is even 500% faster.
improved Altivec support (if applicable)

Bug Fixes :

fixed a missed reinitialization of the track effects on the PlayList
fixed a problem on the scrollbar position when scrolling the waveform while playing the audio file.
