Re: [korgpolyex] New CPU - idea

2014-10-13 by John David Duncan

Hi,

I've missed a little of the discussion but I think I've seen three different ideas:

- replace the 8085 CPU 
- replace the tone generator
- add a tone generator based on a new processor chip

Of these three ideas, I like adding a tone generator best. 

It maintains the value of all the software and hardware work Mike's done so far.
It can be done in a way so that one 8085 code base works both for people who have the new tone generator and people who don't.
It preserves the Poly 800.  By this, I don't mean every facet of the Poly 800 is worth preserving.   I'm glad to see tape support go out the window.  But I would prefer to keep the ability to play the original patches (via some upgrade path) and make the original sounds, rather than simply transform a low-end 1980s synth into a low-end 2010s synth.
