hello,

here are some a137 examples.

a triangle wave with fixed frequency coming
from an a111 vco was fed into the a137 input.

this is the a111 triangle, used as source.

in the first example the parameters of the a137
were controlled manually by hand.

in the second example the parameters of the a137
were modulated by four triangle lfo'S, or to be exact,
by one a143/3 quad lfo.

the a137 can provide so many timbres out of one single vco.
modulations can be subtle or dramatic. for instance you can
do smooth morphs from triangles to skimmed sinewaves, or
you can do those ringing, screaming lead sounds.


also cool for creating unusual effects is when you
use white noise as a137 input. the a137 can modify
noise like no other module i know and it sounds completely
different compared to a filter. good for creating
special effects like the crackling of old vinly.
