I didn't realize you had 36 separate regions (and EQs) to manage. How about this then: Set up the EQs as you need them for each region, and save them as unique channel strip settings. Number them to match the order of the regions. Then simply use the "next channel strip setting" command to call up the new channel strip (EQ setting) when you need it. Since it is available as a key command, you should be able to assign a midi event to control it, and then just simply program up the necessary midi events to automate the process. There will likely be a slight lag time as it is changing presets. But if you have a second or two between regions, this should not be a problem. -------- Eli Krantzberg http://www.nightshiftorchestra.com Almat Productions
