Doepfer

Hi Paul

I modified the A-121 12dB State Variable Filter, corresponding to a hint
from Dieter Doepfer (In the original version there is a capacitor which
damps some unwelcome resonating behaviour at very high frequencies, but
this capacitor causes a -6dB decreas in the high frequencies in the
Highpass).

Most of the CV1 Input-sockets (VCOs and VCFs) do not switch off the CV-bus.
I broke up the lines on the PCB and rewired them in the way, that now the
socket is a switching socket.

I tried something similar like the A108 with the A122: I fed back the
resonance after 12dB; this sounds very nice, because at 12dB the resonance
is not as cutting and thin as with 24dB. But since it required a high
effort and switching between the two modes was very complicated, I turned
it back.

I built also some simple Modules for other people: CV- or audio-mixers,
AD-envelope, simple-VCAs, panners, step sequencers.

I made the fifth plug of the A-180 as switching socket, so if I plug in a
jack to the fifth socket, the sockets 1 to 4 are one group and sockets 5-8
are the other group.
