Just to give you a heads-up, the next HALion iteration is already in the making. Although there is no confirmed release date yet, I can assure you that there will be some substantial new features and improvements that will answer long time feature requests as well as introduce completely new possibilities in HALion.
We are also investigating your reports about issues in other VST3 DAWs and are in touch with the companies to find solutions. As of today the issues seem not to be caused by HALion. As soon as we have more information to share, we will let you know.
