Subject:ParaGraphic EQ Posted by: BeachDog Date:12/5/2002 3:26:27 PM Hi, Try this if you have a chance... 1. Create a Simple 5 second 440 Hz sync tone. (It's a Preset in the Simple Synth box). Note that it plays at -12 dB 2. Open the Paragraphic EQ and select the Preset... "Remove very low and inaudible frequencies below 20 Hz". 3. Hit OK, or just Preview. Result: The volume is now louder (between -11.6dB or louder). This may sound like I'm nit-picking, and I realize I can reduce the "Wet Out", but shouldn't the level stay exactly the same? If anything, get quieter, not louder. Thanks, BeachDog

Thanks for the link, but I guess I can't see why it couldn't be made "ideal", since it's all digital, and especially since it's not being done in real-time. Thanks, BeachDog
