Thanks for the responses..
Let me explain where I am at with the soft synth world.

As Frank prefers, I also am using Forte[host].
My softsynths consist of Roland's Hypercanvas, Super quartet, Orchestral and DX1.
I also have M-Audio's Key Rig.
I also use Native instruments B4 and FM..

Arranger software, I use OMB and Jammer Live...

Other than SMF playback and single lead sounds, I have found the arranger programs live too uncomfortable, compared to the hardware arrangers..

When I added Key Rig, it has 4 modules and I can insert any of the modules into the GM module, allowing me to add a piano[piano module], synth[synth module], and organ[organ module]..I can mute a part from the GM module and select the channel on another module...Great but you pretty much have to keep a fixed map with the added module channels..for example , maybe a brass synth sound on channel 3, organ on channel 4, and piano on channel 1..

The weakness of the Key rig...a single drum kit,,,it sounds great but without the kits I am use to on my G1000..

Another question,, what do I have to set up to accomodate sound fonts? Please give me specifics..
