Controlling AE modular via MIDI
Now, we will patch a „classic“synth that is playable via MIDI; patch as shown in the example:
MIDI Breakout Cable
(included)
MIDI Cable
to MIDI OUT of
your DAW,
Keyboard,
Groovebox...
?Set the send MIDI Channel of your DAW, Keyboard (or whatever you use) to Channel 1
?Now, AE modular gets MIDI data; the MASTER module converts these to a control voltage (CV) depending on the
played note, a GATE signal (“high“ voltage signal when key down, „low“ voltage for key up, and MIDI timing
informations (MIDI clock / start / stop)
?These signals are available on many modules at the lower sockets of the left row of sockets (named „BUS xxx“)
These can be patched with short patch wires to the corresponding inputs of the module (e.g. the VCO module gets
the CV 1 input from BUS CV - red in the example above); same with ENV module, gate input GT1 and BUS GATE.
?Now, AE modular should play the notes that it receives via MIDI.
?NOTE: The note range of AE modular is limited to the MIDI notes C -1 ... C4; MIDI notes outside this range will be
ignored.
?The MASTER module has two switches: CH1 - OMNI selects the MIDI channel; left is MIDI channel 1, right is OMNI,
that means MIDI Notes from all channels are received. The LEGATO switch changes the behavior of GATE signals on
overlapping notes: with LEGATO ON, no new gate signal will be generated, with LEGATO OFF, a gate signal is
triggered for every new MIDI note.
?The dotted, violet line shows a variant: here, the ENV for the filter is not triggered by the MIDI note, but by the
STEP10 trigger sequencer. The STEP10 iteself gets it‘s clock from the BEAT DIVIDER module; the BEAT DIVIDER
takes the MIDI clock (which are basically 1/96th notes - very fast) and slows them down to 1/4, 1/8 or other selectable
measure.
?Now, you can set switches on the STEP 10 to the upper position, and for these steps, a trigger is generated for the
ENV module.
?The result is: The pitch is controlled by the MIDI note, the rhythmical structure for the filter modulation by the
STEP10 sequencer.
?If you want to trigger the volume envelope (second ENV) just patch another wire from STEP10 TRIG OUT to the
GT1 input of the second ENV.
Conclusion
I hope you enjoyed this first look into the world of modular synthesis with AE modular; this Quick Start Guide can give
only a very short overview to get the thing making sound, but has given (hopefully) a first idea how the things work.
Feel free to experiment! Try connections as you like, listen and try to understand „why does this sound like this“ or
„why do I hear nothing“ (what also can happen...)! E.g. from ENV to VCO CV, from one oscillators output to CV / PWM
/ SYNC in of another, with LFO output to everywhere... If you are lost, just get back to the simple patches that are
described here.
Please also take the time to go through the detailed brochure that will be available soon (and sent for free to all
Kickstarter backers who purchased a device, or otherwise available in the webshop).

QUICK START GUIDE
You have received your AE modular, now you want to get sound out of it! This short guide shows you the first steps
into the world of modular sound synthesis, which may look a little challenging if you are used to“normal“ synths,
whether that is hardware or software synths. With a Modular, there are no presets, you have to patch the entire signal
flow from scratch, you could say you build a new synth every time ;-) Don‘t worry, this sounds more complicated than
it is; if you take some time and patience (which is definitely necessary) following these examples you will soon discover
the potential and fun of this device.
Happy patching!

internal connection to the module; they can be used to split or
„multiply“signals (similar to the multiple outputs described above)

Exploring the FILTER

?Connect the Output of the first oscillator on 2OSC
with the input of the filter (shown in red) and
output LP (Lowpass) of the FILTER to the
MASTER, our main output to the speakers (shown
in green).
?Turn RESONANCE on the FILTER fully left; move
FREQ and listen to the opening and closing of the
filter.
?Increase RESONANCE and try combining with
changing FREQ; the more RESONANCE is
increased, the more the filter starts to „ring“ listen!
?In parallel, try different Oscillator frequencies, and try also the sawtooth wave of the oscillator (red dotted
patchline).
?Finally, change the output of the FILTER to BP (Bandpass) and HP (Highpass); tweak the frequency and resonance
and enjoy the wide palette of sounds!

Modulating the FILTER

double the speed, then adjust if desired), so you
get a kind of percussive beat
?The S&H module is a so called Sample & Hold; it works as follows:
- there are two inputs, one for a signal (IN) and
one for a trigger (TRIG)
- if the trigger signal goes high, then the
momentary value of the signal is frozen and sent
to the output
?So what is this useful for? The classic application
is to get some random control for modulation;
but where do we get a random value as signal
input for the S&H? The answer is: NOISE! Noise is
a randomly fluctuating waveform which is the
perfect source for this case.
?In the example, the LFO is again the source for
the „beat“, in this case the trigger of the S&H
(blue); The A output of the NOISE is the signal
for S&H (green). This means the random noise signal is frozen on every clock from the LFO
?The output of the S&H goes again to the CV 1 in of the filter, and when turning up the CV1 knob on the filter we
hear a randomized opening/closing of the filter. Quite nice rhythmic structures!
?BTW: If you want to hear the NOISE directly, patch NOISE -> FILTER -> audio output; tweak FREQ of the NOISE
module and also FREQ / RESONANCE of FILTER - all kinds of wind, waves.... will be audible.

It‘s quite common that you want to mix two or more sound sources; for
this there is the MIXER 4-4 module. It offers 4 audio inputs (A1...A4)
with mixing knobs, the output is OUT A. Additionally there are 4
inputs for control voltages; these are mixed at full level and sent to
OUT B.

NOTE: Here, we have used the ENV for modulating the FILTER, the other typical application of an envelope is to give
the sound a volume contour with the VCA - we‘ll see this later when controlling AE modular by MIDI. At the moment
we are still dealing with a static tone.
