[sdiy] ASM-1 VCO: Sensitivity of linear FM Inputs?

[Michael Zacherl]

Hi List,

I just went through the description of the ASM-1 
VCOs and found follwing note:

"The 560 kohm input resistors for linear FM can be 
made whatever value you want, with smaller 
resistance allowing for wider FM sweeps. 560 kohms 
is just copied from Electronotes."

What's the sensitivity of this inputs with this 
560k resistor? How many Hertz per Volt (appr.)?

Thanks a lot,
    Michael.
