This major update introduces a completely new audio engine with improved stability and support for multicore processors, as well as many workflow enhancements and a reworked VST 2.4 implementation for optimal VST plugin support. Furthermore, it is compatible with Microsoft Windows Vista now.
The update is free for all Orion Platinum 7 users. Orion PRO is discontinued with this 7.5 release and will not be updated further. However the upgrade to Orion 7.5 will be available to all Orion PRO customers for a limited period of time and costs only $49 instead of the former price of $99.
Other news from Synapse is that Orion-Reloaded is online now. The new community site for Orion users, formerly known as Orion-Center. The site allows sharing songs, presets, wavetables, samples as well as tips+tricks between users.
