Doepfer

Hello all.
 
 Please forgive me if these are repeat questions and feel free to 
direct me to relative post #'s.

 I am about to send some ideas to Doepfer to address on their DIY 
page, but first want to see if any of you guys/girls (I'd like to 
think, anyway) have tried these mods.

1.  The schematic for the A-110 shows Linear FM and Soft Sync 
options.  Are these possible?  

2.  What value pot/resistor would need to be added to make a Fine 
tune control for A-110, and where to connect on circuit board?  I 
compared 110 to 111 visually, couldn't decide....

3.  Has anyone added CV control to A-140, 145, 146?  

4.  Has anyone tried to add Resonance Insert to any filters, 
especially the Wasp?  I did.....mixed results.  

  All replies are welcome.
