Change the Volume level, then Save the instrument with a slightly different name.
Also, it would be worth letting Technical Support know about the problem sounds so that they can investigate.
Search the FAQs first, via here. If they do not resolve the issue, there is a
red button link to the Technical Support form, for some one to one investigation and help. Response time aims to be within 2 working days (US (East Coast) Business hours, generally), but in the current circumstances please allow some more time.
And, to help others who run into a similar problem, please let us know what you did to resolve the problem. Please do not quote directly any correspondence from Support, as that may apply only to your particular circumstances and may lead others down the wrong track.
