Care to guess what gobs of resources your beloved Lex 200 had? That was the 1980s.
who knows what the consumption of resources the Lexicon uses, I do know that it has two, full sized circuit boards and they are full of ICs.
If it could be compared to Altiverb, the Lexicon 200 would be insignificant because the Lexicon does not use Impulse Response technology, which is pretty
demanding on RAM and processor useage, but by today's computer specs, Altiverb is no problem for even laptops.
