Well, I think that you'll need to find out where it is installed in your system. Then, in the plug-in manager, which you access from the tools menu in Sonar. Unfortunately, the plug-in manager will not have focus. You will need to go to the top of the window with the jaws cursor, then arrow down to VST instruments and left click. Once you have the plug-in manager in focus, press alt O to go to the vst options dialog. Go to the add button and browse to the path where your haylian's dll has been installed and press enter. Then tab to the scan plug-ins button and press the space bar. After the scan is done, you close the plug-in manager with alt f4. I know this all sounds a bit confusing, but it is the only way to do what you need to do. Gord ----- Original Message ----- From: A.

And I thought that you might missed my email among many things you have to answer, That is why I am copying that last email once again here. I do not want to sent duplicated emails to the list not to bother people who are not really interested in the subject but I have problems with Sonar and need help. Thanks Caglar Hello Caglar Are you familiar with using the plug-in manager? Is Haylian a vst or a dxi or a rewire device? I would need to know this to give you proper instructions. Gord Hello Gord, Unfortunately No I am not familiar with using the plug-in manager. On there web side they call it HALion - The VST Sampler. Then I think it is a VST. Thanks Caglar
