Hi Ingo
Thank you! Your examples helped me to complete clarify the essence of
this phaser now the key is experiment.

Subject: 1 vactrol phaser example


hello list,

despite the things i wrote yesterday, i had some time
to do a patch with the vactrol phaser. it may be a bit
unusual soundwise, but i had so little time. maybe next
week i can do some more typical things with it.


1.

first i created a synth line with the following modules:
2x a111, 1x a138, 1x a185, 1x a131, 1x a142, 1x a145,
1x a102, 2x a155, 1x a154, 1x a156

nothing special here i guess. this is the sequence
without the phaser.

2.

this sequence is then used to feed the vactrol phaser
in "6-stage mode", this means that only half of the module
is used. an a147 lfo (which is controlled by an a155)
is used to shift the phase. also a bit of positive
feedback is applied.

3.

ok, now we are leaving the standard. the stage 4 output
is patched into an a137 wave multiplier. the a137 output
is going into an a132 vca, which is modulated by an
a147 lfo (the same one which sweeps the phase).
the a132 output is then patched back into the
feedback 1 input.

4.

now a second feedback loop is applied.
stage 2 output is patched into the feedback 6 input,
which emphasizes the higher frequencies a bit.

ok, thats all for now. i'll be back on monday.
