Spalding, dont worry, when I have time I'm here to try to explain you untill you have understand how is working the MS and the possibility that we have.
First, look again the styles video, because I had starting playing styles with GIGA drums and then I had swtich to GM/GS styles only and back again to GIGA style.
The 3 GIGA drums was developed from Groovepark germany and the files are about 20Mb each.
For loading this GIGA files the Linuxsampler need about half second and when is in PC chace I can switch the styles without latency.
So, the concept of the MS arranger work in this way:
1) we must have all the 16 midifiles patterns in one folder, the folder name will be the style name.

2) After i have all the midifile, I touch the function key EDIT:

http://www.lionstracs.com/data/gui/chaedit.png and here about the GIGA:

So..now about your VST question, YES is possible routing the styles to the VST plugins too.
http://www.lionstracs.com/data/gui/styleedit.png each preset will recall the right program change of the desidered destination.
If you look again the Video about the VST connection, I can open the Kontakt and connecting where i like.
the arranger have the MIDI OUTS and I connect it to the kontakt and then I can use the kontakt only OR a mix of other device.
http://www.lionstracs.com/data/gui/jackmidi.png when is connected ONE time ( you can also make a Jack presets) you dont have to touch there nothing, all is connected and you will play the MS normally.
Other MS possibility:
we know that with VST we can have latency for loading the samples, BUT who told us to use the only VST or GIGA??
IF someone like the Roland sounds only, they can buy one external Rack expander, like the Fantom XR, OR Ketron SD2, AKAI sampler...what better you like, you will have the totally FREEDOM.
Chose one external module, connect the MS midi OUT to the module IN and the Audio OUTS of the module in the MS LINE IN L+R.
Now this soundmodule is INTEGRATED in the MS system.
You routing the arranger midi out to the soundmodule and RE EDIT one of the 12 style sound preset with the right prg, Var of your desidered module.
Or still you can connect the MS keyboard to the module and play his sounds ONLY.
IF the yamaha will make one Tyros 2 sound module, the MS can have the totally SAME sounds integrated.
Today is saturday and I dont have fun to make a new video.
Monday i wil make one video and shown you there how I can edit the sounds styles, with GM and Giga.
