Assembly & Installation
The MD unit needs the Doepfer DIY Synth board to work, it is
sold separately. If you have bought a bundle, chances are that the
dealer has already mounted the board for you. If not – the
installation is extremely easy and straightforward, just please read
the following steps carefully to avoid problems.
1. If your DIY Synth is equipped with a tempco, unplog its
cable from the onboard socket.
2. Plug the tempco connector in the respective socket (1) on the
back of the MD unit. It is located to the right of the power
head (2)
3. Now, push the DIY Synth on all the headers (3), very gently.
Observe the goldpins carefully to avoid bending them.
Attention on the 2 sockets (4) and (5).
4. Make a connection from the power socket (2) to the busboard
of your cabinet. The red string indicates the -12V rail on the
module (dot mark). Measured the 5V Voltage on the testpoint
TP1 (5.000V). trimming with R19 2K Trimmer. Caution!
The MD unit is NOT secured against reversed power
connection.
5. Mount the screws and turn your system back on. If your
system working the green and red LED are blinking.
Controls & Operation
The panel has been laid out in most obvious monosynth style manner. We took
advantage of all inernal patchpoints provided by Doepfer. Also, there are normalled
connections made behind the panel so you can use the MD as a selfcontained analog
synth voice without even plugging any patch cables in. These fixed connections are
marked by with respective function typed within the [BLACK BOXED]. Of course, the
real fun starts when you break them by simply patching anything into their respective
input jacks.
The synth sconsists of 7 modules: VCO (9), LFO (14), VCF (10), VCA (11), ADSR
(12), Slew limiter (13) and inverter (16). All of these can be used independently. For
rurther information, lease refer to the the Doepfers DIY Synth manual.
Modification: Fixed VCF outputs are now mixed in different configuration and the vca
offset can be adjusted by the trimpot (8) on the back.
By design, the VCF resonance is provided by feeling the output back in. We found it fun
to actually open up the feedback loop for routing the signal outside (any output) and
back (RES FDBCK IN SOCKET (15). Now you can obtain some interesting results
with the external threatment through effects, filters, etc. Happy experimenting!!
