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 Dieter Doepfer > -----Ursprüngliche Nachricht----- > Von: xxxxxxx_xxxx@xxxxxxxxxxx.xxx [mailto:xxxxxxx_xxxx@xxxxxxxxxxx.xxx] > Gesendet: Freitag, 14.
