Dave Smith Instruments SYNTHESIZERS

Wait,  I think I got it

The two nibbles make up the single byte,  
M - most significant
L - least significant

The byte is MMMM LLLL

Binary of 100 is 1100100

My most significant is 0110
Least significant is 0100

Dave splits these two parameters up b/c some of the parameters on the
evolver go higher than 127.

To enter the last few entries of the Program Parameter I sent out earlier

0000 vvvv   Paramter value, LS nibble
0000 vvvv   Parameter value NS nibble

Will be

0000 0100
0000 0110

And finally
SWEET!  :)


Thanks for your help!!!!!
