Yes, Gizmo somehow affects the sound of Ramzess aircrafts. It appears to be all scrambled when gizmo plugin is loaded. I think this issues were already made public, sorry if i´m wrong. Until the corvalis last update, it was ok because gizmo was only used to activation purposes, but now that it´s used inside the plane, the option to not use gizmo is not in my side anymore. But don´t get me wrong. The update is great and the use of gizmo raise the bar with xp addons. The problem is only with incompatibility with others addon´s that are already in the market. And i´m not a xp geek to debug all the possibilities that can cause problems. ;D I´m using xp in win 7 64. The other plugins that i have are FJCC_UFMC, PilotView, Checklister and ChaseViewDeluxe and many other aircrafts, including the crj, marquise, seamax, etc. For now, i will zip gizmo and only use it when i fly the corvalis. It´s a simple workaround that i thought only later after my previous post above. : Thanks!
