Please excuse my wordiness.
I am a long time owner/user of GOS and GPO but, because of my work as a psychiatrist, have only recently been able to begin to attempt to use them productively.
I am in the process of finishing up my dentry to the Orchestral Challenge 5 and am having difficulty with aliasing leading to a nasty distortion in several instruments.
I have a pentium 4 3.0 ghz box running Windows XP pro. 2 gig of memory
I have two echo sound cards - Layla 3G and Gina 24 daisy chained with the Layla as the master.
I am running the ASIO drivers in Sonar 4 and have a tmeplate loaded with 6 instances of GPO VST. Challenge 5 is a modestly thick orchestration. There have been few problems with the exception that I am getting a lot of distortion of the sound of Trumpet 1. Especially noticeable on long held notes. There are no other instruments in unison with the trumpet and the distortion is noticeable to a much lesser extent in other instruments.
Sonar is set for 24 bit audio there areno conflicting settings with the sound cards that I can find.
Are there any obvious things that can cause aliasing in a set up like this?
