Sorry for my late reply. But so far I had to A-111-3 available to try it
out. Indeed the A-111-3/A-160-1 combo does not work as it should under
certain conditions (problems occured around 250 Hz A-111-3 frequency). With
an LFO (A-145) or another VCO (A-110-1) with the same frequency everything
was fine. To speak the truth I don't really know the exact reason for the
faulty behaviour in combination with the A-111-3. Maybe it has to do with
the signal level that generates some kind of crosstalk inside the A-160-1
(the level of the A-111-3 is higher than the A-145/A-110-1) and/or the edge
details of the A-111-3 signal. Anyway - I found two solutions for the
problem:
- attenuating the A-111-3 signal by means of an A-183-1 (when the signal
level is lowered the artefacts disappear at a certain knob position of the
A-183-1)
- soldering a capacitor in parallel to the A-160-1 clock input (I tried
1nF - 10nF and all worked)
Hope this helps
