[sdiy] Ray Wilson Filter question

[synth at oldmail.charlielamm.com]

I am trying to use this Ray Wilson filter in something I am building:

http://www.musicfromouterspace.com/analogsynth/statevariablefilter.html

I am using +/- 15V instead of +/- 12V.  

I am also using mod CV of 0 to 5V--the circuit looks to me like it expects 
0-10V for a good sounding filter freq sweep?

To make this work, I think I need to change R6 to about 47K for the 0-5V
CV for freq mod, and R14 to about 180K to accommodate the greater supply
V's.  I can't think of any other mod necessary.

Can anyone else?  Are my subs OK?

Thanks in advance for any help.  --Charlie Lamm
