ASM-1 sync amount

[Josue Arias]

Hi there,
I´m finishing my ASM-1 synth (2 ASM boards) and I´m trying to add some
features and aditional modules to complete the system.
I´d like to control,the sync amount in the oscillators. I use a lot the
"weak" sync output in my System 100, and I think that a soft or medium
sync is more "usefull" than hard sync...
Do you know if thre are a easy way to have Sync amount in a knob in the
front panel, or may be 3 different inputs?
I´m building the ASM1(with many difficults) but I don´t know pretty much
about electronics. All info is greatly apreciated.
Thanks!

Josue Arias.
