Guys - I need some help recreating about 10 seconds of sound from a classic prog tune

Hi - I am working up a recreated version of a Dixie Dregs song, called Night Meets Light, with real guitar and everything else midi.
 
In the early part of the song, there is some sort of a synth bass part that comes in a little after the 30-second mark, and then the tone changes as it is played over about the next 10 seconds, where there is distortion added to the sound.
 
I am trying to figure out how I can recreate that sound, using the soft-synths and effects that I have.
 
Here is a link to the song in YouTube, and the synth bass part starts coming in around between 30 seconds and about 40 seconds into the song.  Over that 10-seconds the distortion gets cranked up on the sound, but it doesn't actually get much louder, just more distorted.

My soft synths include Native Instruments Komplete 8 Ultimate (Kontakt 5, Reaktor, Massive, FM8, Absynth), and I also have the Arturia V Collection (recreations of Minimoog, Modular Moog, Arp 2600, Juno 8, Prophet, CS80, Oberheim SEM), as well as what comes with Sonar X3 Producer.
 
I can't quite figure out what T Lavitz originally used for this - it seems like he used a Minimoog for a lot of things, but I cannot quite get the sound quite right.
 
Thank you SOOO much for any attempts at assisting me with this - it is a project from the heart I am doing for a guitar playing friend of mine (he is playing all of the Steve Morse guitar parts for our rendition of it), and I am adding drums, bass, violin, synth bass, and keyboard lead for the project.
 
It is a beautiful song, and I want to give it my best shot.

Maybe I can do it that way - thanks - I will give it a shot tomorrow.
 
The original Minimoog didn't have any sort of velocity, if I recall correctly.  We had to do all that with the modulation wheel - of course that makes sense now that I think about it - I'll try that.
 
Remind me to put you in my will.  :)

Thanks for your help - I will give it all a shot this afternoon and post back later on.

Thanks guys - my son came over last night, and after literally 12 hours in the studio, he crashed HARD, so I will chill out for a bit and play some Black Ops 2 until he wakes up, and will then give this all a try.
 
I did manage to hook up a couple of additional speakers down there while he was snoozing, and am now just going through plugin updates and such, and some COD.

Thanks - it would be my honor to have you listen to it.
 
It will likely be November or so until it gets done, as I am moving in 2 days, and I also will separately be heading to Chicago - 900 miles of driving each way - for the month of October.
 
As soon as it is done, I promise I will post it.
 
If interested, I am also working up midi versions of:
 
UK - In the Dead of Night
Jean Luc Ponty - Mirage
Bill Bruford - Fainting in Coils, Sample and Hold, Palewell Park
Dixie Dregs - Twiggs Approved - and eventually also I'm Freaking Out.
 
I will keep you posted.  Thanks again for the interest :)

sounds like your progressive tastes are right up my alley...
 
i have favorites, but i like everything from atomic rooster to zappa.
LOL
 
i'd say, dregs, brand x, diMeola, holdsworth, Ponty, weather Report, could all be listed as early influences
