MStereoExpander 5.01 is considered as a smart yet professional program offers expansion based on either actual sample or delay, and provides stereo field modification to increase or reduce the clarity of the spatial differences between channels. 

1. Expansion based on actual sample or delay.
2. Perfectly mono compatible.
3. Full randomization - using a single button you can generate completely new settings. By clicking the button you can walk through the billions of possible settings and find the best one for you! And if that's too much, you can just hold ctrl and MStereoExpander will only slightly modify existing settings.
4. Adjustable up-sampling 1x-16x to minimize aliasing and get an even clearer sound.
5. Extremely advanced and easy-to-use user interface - products are always designed to enhance the workflow. You can easily change all values, fine-tune each control in multiple ways. Easy orientation in a standardized GUI, textual editing and smooth visualization with almost unlimited zooming are standard in all of plugins. Moreover plugins are the world first (and still the only ones), which support resizable and stylable GUI's.
6. MIDI controllers with MIDI learn - you can map any parameter to any MIDI controller or MIDI keyboard and control it realtime or record and automate it.
7. Very fast, optimized for SSE and SSE2 processors.
8. Global preset management and online preset exchange - using a title button you can save your settings (which are shared on the computer) so you can easily access these in other songs. Moreover all plugins can automatically share your presets and download presets of other users from servers (if this feature is enabled). 
9. Fully automatable.

• Surround is now off by default, because it causes problems with some hosts (known are FL Studio and Studio One). If you use surround processing, please enable "Activate surround" in the plugin settings, it will enable all plugins at once.
• Plugins can now access additional volumes on Mac OS X.
• Band editor in equalizers doesn't close when clicking on a band type any more and shows filter steepness.
• Fix: Plugins could crash in AU when requested mono to stereo configuration.
• Fix: Styles are now moved to user data folder, because some computers have permission problem with all-users directory.
• Fix: MFilter caused massive gain in parallel mode in some special circumstances.
• Fix: Analyzer in equalizers didn't show correct spectrum if activated after upsampling change.
• Fix: MMultiBandConvolution didn't remember custom paths correctly on Mac OS X
