Hmm - i have tried one time annother Program as VST-host, it´s called UNIVATOR.
With the Univator as VST-Host the sound is definitly on my PC not as good, than with Cubase.
Perhaps this could be one reason - it seems, the programms have differencies to handle the sound - perhaps by memorymanagement, or by internal "tricks" to handle the Latency - i don´t know - but also for my ears there are Differences between different VST-Host-Programs - especially if you compare a expensive one (for example CUBASE) with a cheaper one - or Freeware...
The Soundsystem itself can also be a reason of big changes in the sound - especially the 5.1 options!! If you playing about a amplifier and change from DolbyProLogic MUSIC to DolbyPrologicCINEMA, or you change to LOGIC7 - try it: ALL this can change dramatically your Sound - depending on your amplifier.
Onother Reason very often is the Velocity. My Digipiano for example is too soft - and so i have to increase the Loudness of my amplifier - but than i´m playing more in the lower regions of the velocity layers - with the result of missing Dynamik.
My Solution was to changet the Velocitiy-curve in the programm and adapt it more to my style of playing. I take attention, that a FF also in the programm geos about 80% of the Rangepossibilty.
On this point you also to think on this point: YOUR Settings making a different sound, than a pure midi-playing!! If you comparing Midi-files with the Demos on the Internet, perhaps you have to changes again the settings different to your own live-playing-settings.
A MForte should not to be too less Loudness. Here you have to tryout to fiind your best solution , adapting your playingstyle and your used Keyboard.
With the right changes, the sound can change from a weak unimpressed sound to a strong and very dynamik Sound.
Often - i think - this couple of different equipment and programm-settings is the reason, some peoples thinking there sound isn´t as good as the Demos.
