Impact Version 1.1 for Pro Tools|HD Accel Systems For Mac OS X & Windows XP March 16, 2004 Impact 1.1 is a free update for all existing Impact owners with Pro Tools|HD Accel systems on Pro Tools 6.2 and higher. Impact 1.1 uses the same iLok authorization that previous versions of Impact use. Important Announcement Software Bug in Impact Compressor Plug-in for Pro Tools|HD Accel Systems Our recent release of the Impact plug-in for Pro Tools|HD Accel-powered Pro Tools systems contains a bug which prevents Impact from producing the useful, "musical" compression for which it was designed. We've posted a downloadable update here. What is the Nature of the Bug? A bug was introduced very late in the development process, after our listening tests, when code used to control and smooth the meter ballistics on the user interface was accidentally inserted into the compressor DSP code that calculates gain reduction. This bug extends the Impact compressor's attack time far beyond the time shown on the GUI. The user interface shows a minimum attack of .1 ms but even at the .1 ms attack time setting, actual attack times are approximately 200 ms. What is the Audible Effect of the Bug? With an attack time that long, it's not possible to create many of the types of sounds you'd like to get from a good general purpose (or mix bus) compressor. For example, if you want to pass the attack transient of a drum, but quickly bring up the "body" of the sound by using a relatively fast attack along with a fast release, or when you want the mix to "pump" in a musical way, the compressor's attack time needs to be somewhere between .1 and 15 ms. If the attack time is set too high, these effects can't be achieved. We recognize that this is a pretty major shortcoming, and we'd like to apologize wholeheartedly on behalf of Digidesign to anyone who tried Impact and found it fell short of their expectations. The plug-in now functions correctly, and the attack is accurate as labeled. We think you'll be pleasantly surprised by how great the corrected version sounds. There are no other side-effects of this bug (for example, no damage done to your audio). So if you already liked what Impact was capable of, you can install the newer version of the plug-in knowing that you can create some of the same sounds as before by setting the attack far slower on the GUI, and also get some great new results using faster attack times. Again, we apologize for the inconvenience caused by this bug, and encourage all users to download the updated, corrected version of Impact. What's Fixed in Impact 1.1 Impact 1.1 contains the following: Fixed: The Impact compressor attack time now functions with settings as low as .1 ms (Item #46923)
Includes Fix from Impact 1.0.2 Fixed: Impact Multichannel Instances Can Become Unstable
and Mute Audio When Sharing the Same
