If The Access Virus TI is hardwired how can operating systems updates add so much

[Newly Accessed]

Hello,
Can someone explain to me how The Access Virus TI has had so much added to it through operating system upadates if it is a hard wired synth?

By the way how can a hard wired synth have so many mod matrix options as the Virus TI has in its sources and destinations?

Thanks for any info.
