1 Quick start
Welcome to the . The is a very flexi-
ble generic CV processor. It can do almost any CV task
you can imagine, such as sequencing, melody generation,
slew limiting, quantizing, switching, mixing, working on
clocks and triggers, creating envelopes and LFOs or other
fancy voltages, or any combination of these at the same
time! While doing this, is very precise both in volt-
age and in timing.
You tell your what to do by means of a sim-
ple text file called “DROID patch”. That file is be named
droid.ini and is located on a micro SD card. No spe-
cial software is required for writing that file. A simple
text editor running on Windows, Linux, Mac or any other
device will suffice. If you have an X7 expander attached
to your master, you can access the memory card directly
from your PC or Mac via a USB-C cable.
The building blocks of a DROID patch are called circuits.
Every type of circuit performs some basic task. Just like a
Eurorack module each ciruit has inputs and outputs. You
can wire these either directly to some of the inputs and
outputs of the module or even connect them in-
ternally in order to create more complex networks of cir-
cuits.
A first patch example – step by step
Let’s do a first simple DROID patch!
1. Install your DROID master into your Eurorack sys-
tem and power it on.
2. Remove the shipped micro SD card from your
DROID master und put it into the micro SD card
reader that also as been shipped with your DROID.
Insert that reader into a free USB port of you Laptop
or PC. (Alternatively, if you have an X7 attached,
connect the X7 with a free USB port of your com-
puter and put the switch on the X7 to the left).
3. Locate the file droid.ini on that card with your
file browser (Explorer, Finder, whatever) and open
it with a text editor (like Notepad, TextEdit, VIM,
Notepad++, etc.).
4. Delete the current contents of that file and type the
following:
[contour]
gate = I1
decay = 0.2
sustain = 0.5
release = 0.3
output = O1
5. Save the file back to the SD card, eject the card
properly and then remove it from the reader.
6. Insert the card back into the DROID master – with
the visible pins facing downwards.
7. Press the button left of the card slot
If you have an X7, simply put the switch back to its cen-
ter position after ”ejecting” the SD card with windows /
Mac. It will then automatically load the new patch with-
out need to press the button.
Your DROID now will read in its new patch. If everything
goes well, it restarts with its rainbow color animation. If
not please check your DROID patch and repeat the proce-
dure. Refer to page 7for how to find the root cause of a
problem.
This first patch creates an ADSR type envelope that is
triggered at input jack 1 (I1) and outputs its CV on output
jack 1 (O1). For the parameters A, D, S and R fixed values
are being set for the while.
Now within the every parameter can be controlled
via CV. So instead of setting the release to a fixed value of
0.3 you can use the second input (I2) for CV controlling
that. This is easy:
[contour]
gate = I1
decay = 0.2
sustain = 0.5
release = I2
output = O1
If you have a controller such as the P2B8, the P4B2 or the
P10, you can use pots for controlling parameters. First
of all – for each P2B8 you need one line with the contents
[p2b8]. Likewise for a P4B2 you need the line [p4b2] and
for a P10 the line [p10]. (Note: If you mix P2B8s, P4B2s,
P10s and other controllers, the order of these controllers
in your chain must match the order of the declaration in
your DROID patch.) Now you can access the first pot of
your first controller with P1.1, e.g. in order to control the
sustain of the envelope via that pot:
[p2b8]
[contour]
gate = I1
decay = 0.2
sustain = P1.1
release = I2
output = O1
We have not dug into details yet – but you get the idea!
The rest of this manual will show you the wonderful world
of the . First you learn all general ideas and fea-
tures. In chapter 8there is a complete rereference of all
circuit types that you offers.
