hello list,

here is another short sound example of the a111/2 prototype.
this time you hear the composed waveform of the vco only.
consequently the morphing section, vcf and vca have not been
used (knobs set to most neutral position).
the a111/2 triangle wave output is patched back to the cv-wf input.
an additional triangle wave from an a147 is patched to
the a111/2 cv-pw1 input. you hear a short eight-note sequence.
the starting waveform is a combination of sawtooth and triangle.
first the attenuator of the cv-wf input is set from zero to eight.
this switches between different waveform combinations within
one waveform period. then the pulse1 is added by turning the
pw1 knob from zero to five. then the pulsewidth modulation is
added by opening the cv-pw1 attenuator.
after that the wf knob is set from "sawtooth + triangle" 
to "sawtooth". then the pulsewidth modulation is removed,
then pulse1 itself is removed. finally the modulation at
the cv-wf input is fully attenuated. the ending waveform
is a sawtooth.

when viewing this recording on an oscilloscope the waveshapes
might look a bit "noisy", but don't worry, this is only because
of the mp3 encoding.

best wishes
