hello martin,

regarding filters:
if you don't need highpass and notch outs, the
a108 is the better choice in my opinion, but
that is only my personal preference.
the a121 has a more neutral sound, while the a108
sounds "moogy".

regarding a106/1 and a124, i'd prefer the a106/1.

it really is difficult to point you to specific filters,
it's too much a matter of taste.

the a134 is a dual vca. one vca closes, while the other opens.
this can also be done when you invert the panning cv and feed
both inverted and normal cv to the cv-inputs of an a135.
if you need two outputs (the a135 has only one output),
you can do the same with two standard vca's (if you use an
a132, you need to add an offset voltage added to the
inverted cv.

the problem with divided lfo's is that the dividers only
output square waves, you cannot divide triangles or sinewaves,
as the divider will turn them into square waves.
if this is ok for you, then one lfo is ok.

best wishes

ingo
