LFO Destinations

In my subtractive synth I am implementing the lfo section. If I want to modulate the FM amount or any other parameter that isnt signal based I take it I need to have the signal amplictudes of the lfo modulate signal? I am doing this using number~ so I am getting amps of the signal which I then intend to scale and send to the parameters to vary the amount already set by the amplitude values.
The numbers wont produce very smooth modulation of the parameters.

Would that be the best way to modulate those parameters using an lfo?

why is your FM amount _not signal based ?

Well the dial which controller it is not a signal but once it has been put through a *~ it is. Am I better off modulating it at that stage?

absolutely, unless you need to save the CPU
it will need.

connect your LFO as signal to the synthesizer DSP
(or write it completely in signal), then just do
[snapshot~ 25]-[prepend set] to your dials to have
them updated.
