you can use dimension pro, or dimension le, or drop zone, or rxp. i'm not sure if rapture le. the easiest way would be rxp. it is able to load wav files and it has many filter options that are automatable and i think even session drummer can play wave files loaded into the pads and you have a filter also. ----- Original Message ----- From: Stacy Bleeks To: ddots-l@xxxxxxxxxxxxx Sent: Wednesday, September 24, 2008 2:35 PM Subject: [ddots-l] envelope filter? Hi. Anyone know of an envelope filter plug in effect that works with the Sonar/CakeTalking combo? Envelopoe filter might be called other things too, but it is the effect that sort of muffles a sound and allows you to open the soudn again in a kind of swooshing sweeping effect. The envelope can open quickly or slowly with more or less intensity. Thanks and sorry bout my non technical quick and dirty explanation. __________ Information from ESET NOD32 Antivirus, version of virus signature database 3469 (20080924) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
