A-196 PLL System A - 100 doepfer
8
A very interesting variant of this patch is the usage of
the 8 external inputs of the lower A-155 row. Connect
these inputs to 8 different automatically changing con-
trol voltages (e.g. LFO A-145/146/147, ADSR A-
140/141/142, Random voltages A-118/A-149-1, mor-
phing controller A-144) or even audio signals. Automa-
tically varying waveforms will appear.
Another application is the generation of clock signals
for switched capacitor filters (SCF). For these types
of filters the filter frequency is defined by the frequency
of an external clock signal. So far no filters of this type
are available as A-100 modules but we are about to
experiment with SCFs.
The A-196 is a very experimental module and some
of its functions cannot be described straight forward as
for other modules. Rather the user should try out the
possibilities by trial and error.
E.g. the frequency jitter (i.e. actually too high LP fre-
quency for optimal PLL operation) or frequency slew
(i.e. actually too low LP frequency) can be used inten-
tionally to obtain certain effects.
Even the upper frequency limits of the VCOs can be
used on purpose ("frequency clipping").
Usually the three phase comparators behave comple-
tely different within the same patch so that this peculia-
rity leads to additional sound experiments.
