before connecting the modules first add the standoffs to the back of the faceplate to make installation easier.
start from the bottom and continue up leaving the power distribution until last.
to attach the standoffs, place the screw through the hole from the outside and using a pair needle nose pliers hold the standoffs firmly at the back as screwing.
now repeat this procedure for all modules leaving only the power distro without standoffs.
be careful not to over tighten!
the power distro attaches to the frame differently to the other modules. first cut the standoffs for the psu in half using a pair of pliers or wire cutters.
then attach these shorter standoffs to the top of the frame to attach the power distro.
place the front plate face down. tip: put a soft surface such as towel beneath.
attach the modules to the back of the faceplate via the standoffs. it is possible to do this in any order but it is advised to do it going from right to left and top to bottom – starting with mixer – until the speaker module. to avoid crossing power cables and too much tangle.
place the module on top of the standoffs and ensure the jacks are correctly aligned with the holes. screw the module to the standoffs.
ensure the screws on the faceplate are not rotating. be careful not to over tighten. once screwed in place, plug in the cable to the power socket on the right.
this side up!
the speaker module pcb comes with a part that is not needed.
firmly and carefully break off the square part.
take care when installing the speaker as the cable connecting the speaker unit to the pcb needs to fit nicely.
in modular synthesis there are two types of signal. audio signals and control voltages (cv). audio signals are for sounds and cv is for controlling things. these two different signals will be used to connect the different modules together.
this is how sounds and patterns are created in a modular system. the beauty of modular is that you can pretty much connect anything to anything, creating all kinds of relationships and interesting sounds, that all dynamically interact with each other.
that said you should generally avoid connecting outputs to outputs or inputs to inputs.
in a modular synthesizer it is usually the job of the oscillators to make the sounds that are processed by the rest of the system. the 400 includes 3 oscillator types:
a square, a saw and a sine.
lets hear each of them through the 400's built in speaker. first let's make sure the volume of the speaker module is turned down. locate the level knob on the speaker module and turn it all the way to the right.
you can use audio signals as cv for some very interesting results and some cv modules such as the lfo can run at audio rates.
never connect headphones directly to the outputs of the 400. you can damage your ears and your headphones if you do this, so be very careful.
to hear the sound of the oscillator we need to connect it to the speaker. to do this take a yellow cable and connect it to any of the 3 jacks labeled output on the top of the square oscillator. any of these jacks is fine as all 3 will output the same signal. take the other end of the cable and plug it into the jack on the speaker called right.
now we can slowly increase the volume of the speaker by turning the level knob to the left.
if you do not hear a sound it may be that your oscillator tuning is too high or too low. turn the tune knob to alter the pitch of the oscillator so that it is in the audible range. also turn the pwm level all the way to the left.
control voltages are used to control different parts of the modular system. for example in the last example we manually altered the pitch of the oscillator but in this example we will use a control voltage to alter the pitch for us.
continuing from the last patch: set up a control voltage to control the pitch of our oscillator.
use the triangle wave from the lfo. locate the lfo module and plug a cable into either of the triangle outputs.
tip: set the rate to its slowest setting by turning the rate knob all the way to the left.
plug the other end of the cable into the input labeled control on the square oscillator.
turn the knob underneath that is labeled level all the way to the right. you should hear the pitch slowly rising and falling.
now lets change the 'rate' (speed of the control voltage). very slowly turn the knob labeled rate on the lfo to the right. the change in pitch should become faster until eventually we reach what is called audio rate modulation.
pro-tip: audio rate is a term used to describe cycling control signals that move so fast they actually become audible and enter the audible frequency range.
the lfo is actually just an oscillator that can reach very slow speeds. by modulating parameters at audio rates we can get all kinds of interesting effects.
let's patch a simple mono synth including the following modules: [saw
the diagram shows the flow of audio signals and control voltages when patching this mono synth.
first step is to connect the sound source [saw] to the filter. connect a patch cable to any of the [saw] outputs. connect the other end to the jack labeled input on the [filter]. this will pass the audio generated from the oscillator to the filter. now open the filter all the way by turning the frequency knob all the way to the right.
next: take the filter output and connect to the input on the vca. then connect the output of the vca to the left speaker input. turn up both the level and the gain on the vca. you should hear a constant note. if you don't adjust the tuning of the saw oscillator or check that you opened the filter by moving frequency all the way to the right.
the vca or voltage controlled amplifier will control the volume of the signal. it is possible to do that manually using the level and gain knobs. this patch uses the envelope for this.
now connect the envelope output to the control input on the vca. this will let the envelope signal control the volume of the sound. the envelope has to be triggered to know when a note is sounded. we can do this from the sequencer which we will also use to set the notes of the sequence.
connect the clock out of the sequencer to the trigger input of the envelope. the clock pulses will trigger the envelope every step of the sequence. adjust the adsr (attack, decay, sustain and release) on the envelope to get different changes in the volume. try setting attack all the way to the left.
THIS IS WHAT THE FINISHED PATCH SHOULD LOOK LIKE.
now lets make the classic talking filter patch. for this patch we will use the following modules: [square
] and [speaker
the diagram shows the flow of audio signals and control voltages when patching this talking filter.
first connect the audio source to the filter. patch one of the square outputs to the audio input of the filter.
connect the filter output to the speaker. turn up the volume and open up the filter frequency to get a long droning sound.
sine through rand
use the noise and rand to create a stepped filter. the noise and rand modules work as a pair to create sources of randomness in our modular system. take the saw output of the noise module and connect it to the in of the rand module.
the rand acts as a sample and hold. meaning the rand will sample the voltage level of the incoming signal at a rate determined by either the rate knob or clock input. for example: to send a sine wave through the rand will give a stair stepping output. the saw noise output will be used for this patch. the saw noise creates a random pattern making it possible to create unpredictable results. this can be useful for adding an element of surprise to your patch.
for this patch, take the rand output and patch it to the filter frequency input labeled control on the left of the filter module.
set the filter control level input to max and adjust the rate and level on the rand to create a talking filter patch.
it is also possible to patch the sequencer output to the square oscillator key input and at the same time patch the sequencer clock out put to the rand clock input to get a different filter frequency for each note.
using the oplab module
it is possible to control the 400 from the OP-Z. to fully use the oplab module you will need two splitters cables (y cables). the stereo cables provided with the 400 also work but will only give access to the basic features of the ZM-1 module.
when connecting to effects pedals it is very important to be careful with signal levels. it is possible to damage your pedal by running the audio through at full volume. always start with the volume at minimum and slowly raise it to the correct level.
it is possible to integrate 400 with other modular systems and semi modular synths.
why not try connecting in some extra envelopes from your external system?
unlike most other audio equipment, modular synthesizers output audio and control voltage at much higher level (voltage) than other studio equipment. for this reason we recommend the following precautions and practices.
do not connect headphones directly to the 400. you can damage your headphones or much worse your ears.
do not plug outputs of the 400 directly into equipment that is not designed to handle the larger voltage. for example, pocket operators, effects pedals etc. please consult the manufacturer of the product in question if you are not sure.
it is generally advised that you avoid connecting inputs to inputs or outputs to outputs. doing so can put unnecessary strain on the system and over time may eventually lead to damage.
square is a square wave oscillator that can be used both as an audio signal and as an lfo, to control, trigger and modulate other sources.
pro-tip: with pwn set to above 50% no sound is heard. this can be great when modulated to create interesting rhythmic effects.
these three identical outputs can be used simultaneously.
control + key
these are inputs for controlling the pitch of the square waveform. key is set to 1v/oct, and control can be scaled by level.
turn level to adjust how much any incoming control signal should modulate the waveform.
pulse width modulation or pwm input can be used to shape the waveform by offsetting the ratio between maximum and minimum voltage. try patching any signal through the pwm input to hear what this sounds like.
adjust the pwm level with this knob. if nothing is connected to the input this knob acts as manual pwm control. if you can't hear anything make sure to turn this all the way down.
tune sets the main frequency of the waveform. if you can't hear anything try setting this to somewhere in the middle.
saw is a sawtooth wave oscillator generating sounds rich in overtones. it can be used both as an lfo and as an audio signal.
these are inputs for controlling the pitch of the saw waveform. key is set to 1v/oct, and control can be scaled by level.
this is an input for linear fm or frequency modulation of the saw waveform. use this to modulate the original waveform into more complex shapes. try running any signal through the fm input to hear what this sounds like.
when something is connected into fm you can use this knob to adjust the amount of fm.
sine is a sine wave oscillator generating a fundamental frequency without many overtones. use it as an audio signal or as an lfo.
pro-tip: sine waves are great for fm modulation. use it as a control voltage source for your filter with an increased resonance for some cool vocal sounding filter fm effects..
these are inputs for controlling the pitch of the sine waveform. key is set to 1v/oct, and control can be scaled by level.
this is an input for fm or frequency modulation of the sine waveform. use this to modulate the original waveform into more complex shapes. try running any signal through the fm input to hear what this sounds like.
the mixer can be used to sum three signals into one.
pro-tip: the mixer can be used to mix audio signals but it can also be used to mix control voltages. for example both lfo and one envelope can be mixed into one control signal. for best results do not mix audio signals with control voltage signals.
mixed output for any incoming signals.
level control for first input.
level control for mixed output.
level control for second input.
level control for third input.
rand is short for random and is a sample-and-hold module. patch anything into the input and it will sample it and generate a random output signal based on that. a good source for the input is the saw noise.
these are the two outputs for the random signal. they are identical and can be used simultaneously.
this is the input for the signal being sampled. make sure you have something patched into here to get an output from this module.
if you want rand to be tempo-synced then patch a gate signal into here. this will override the manual rate knob.
turn this knob to adjust the level of the incoming control signal.
this knob sets the rate of which the input signal is sampled, unless something is patched into clock.
lfo is short for low frequency oscillator. this one has four outputs, two square and two triangle waveforms. it can be used to modulate any control input.
these square wave outputs can for example be used as gates to trigger the sequencer clock, or the env and rand modules.
try patching these triangle wave outputs to any control input, for example to modulate the filter cutoff frequency, the pitch of the oscillators or the amplitude of the vca's.
use this knob to control the rate of the lfo. at high rates the frequency goes into audio range.
env is short for envelope. adsr stands for attack, decay, sustain and release, and when triggered it is a control source for shaping a sound over time.
this outputs the control signal used to shape the sound. try patching this to any control input. these two identical outputs can be used simultaneously.
patch a control signal into this input to trigger the envelope. you can for instance use one of the sequencer outputs or any clock or gate signal.
sustain level. this is the level at which sustained notes will be held.
vca is short for voltage-controlled amplifier. patch any signal through this module to modulate its amplitude, such as changing the volume of a sound.
whatever is patched into in gets modulated by control, and then back out through here. these two identical outputs can be used simultaneously.
this is the main input for the vca. patch whatever audio signal you want to modulate into here.
this is the input for the modulating control signal. try patching the output of an env into here.
this knob adjusts depth of the control signal.
this knob adjusts level of the input signal.
noise outputs two types of continuous noise, great for adding texture to any signal or for generating randomness in a patch.
white noise output.
saw noise output. this is a unique noise source that uses a saw wave as its basis.
filter is a resonant low pass filter that allows you to shape a signal by filtering out high frequencies.
(left + right)
these are inputs for controlling the cutoff frequency of the filter.
this is the input for the filter. patch whatever audio signal you want to filter into here.
(left + right)
turn level to adjust how much the incoming control signal should modulate the cutoff frequency.
this controls the resonance of the filter. turn this up to emphasizes the frequencies around the cut off point to get a sharper thinner sound.
this controls the main cutoff frequency of the filter. turn it down to only let low frequencies pass through. if you don't hear anything try turning this all the way up.
sequencer is a 16-step sequencer module used to control and modulate everything on the 400 or external devices. this can be used to create melodies or rhythmic patterns, by patching an output to a control input.
each of these two outputs sends a clock trig based on the tempo used.
left / right
patch a trig signal into here to reverse sequencer running direction.
these are the three main outputs of the sequencer and they can all be used simultaneously.
adjust this knob to set the internal tempo for the sequencer, if nothing is connected into clock in.
use an external clock and patch that into here to have the sequencer follow the external tempo.
whenever this is triggered the sequencer resets to the first step.
D1 – D4
these are binary inputs for addressing individual steps of the sequencer.
this lights up whenever the first step is triggered.
turn these knobs to set the level of control voltage sent to output, for each corresponding step. setting a knob to max will shorten the sequence and play only the previous steps.
speaker is a dual input speaker module allowing you to to hear what your patch sounds like.
this is the volume control for the speaker module and for the output. it is reversed so turn it counterclockwise to turn the volume up and clockwise to turn it down. note: when using the speaker or the output always be careful with your ears and equipment.
