ASM1 LFO influance?

[e]

Hi all

small/big problem
The LFo of my asm1 seems to influance the hole synth somehow
(offcourse it is unpached!!)
example
i probe the vco and when i play with the lfo rate
some VERY minor fluctuations seems to appear to the amplitude of the vco
the fluctuation are apparently an lfo function on the pitch.
but it is barely noticed , only by scope or very concentrate hearing.
it appears in both vco's and both shapes.

when i changed the rate i can hear the rate faintly changes on both vco
thats how i related the lfo for the cause.

tnx
