[sdiy] FPGA based synthesizer progress....

It is slow progress, but it is being made.  I just got the envelope 
generator core working.  This sucker was a lot more difficult to do than 
I thought.  It implements 512 ADSR envelope generators that can run at 
96K samples per second.  I already have 512 NCOs running...so, now all I 
need to do is get the VCA/Mixer running and connect that to my I2S 
core...and I will have a simple digital synthesizer with 512 voices...

As soon as I get this done, I will be posting it...on my website, and 
maybe Opencores.org.
