Sat arvo Jam - 10th Jan 2017

A great way to spend a Sat arvo with Paul (aka Cobramatic) ,
Messing around with some euro mainly today.   ....and a video synth and a the Makenoise 0-coast.

Paul showed me some great new modules .. two by Intellijel... the Rain maker & Plonk.
These are both digital.

A post shared by jono (@dj_jondent) on
The Rainmaker.... it a deep complex digital sound processor that can create resonant sounds that go into the "pseudo physical modelling territory". loads of precets.
Its much more than just a delay.
It has 16 taps, each with has its own resonant filter (LP/BP/HP) and granular pitch shifter.
In addition to being able to save the type of filter at each step, you can set resonance & cutoff frequency.
They can even self oscillate . The pitch shifter has a range of +15 semitones to -16 semitones.

Plonk.
You can probably view this as a drum module that specialises in making percussive sounds... natural and unnatural. I've never really been into digital, but i was impressed with this one. i´m absolutely in no doubt that the Plonk will pair VERY well with a Rings.
The Plonk definitely emits very realistic sounds of the mediums it tries to emulate but it's capable of some very alien sounds too!


It's not a samplier, it uses physical modelling. A microprocessor calculates the type of sound that is produced ...depending on the characteristics of the membrane (called the resonator) and the percussion device (the exciter). 

So its uses mathematical modelling.
Plonk offers several types of resonators: beam; marimba; drumhead; membrane; plate; and string.
There are 2 types of percussion devices: a mallet and a noise source.

There are 128 user preset slots with import/export via USB. These come filled with factory presets designed by Richard Devine and AAS.

 --------------------

The video synth I tested yesterday ia the new Vidiot by LZX.
It arrived only Friday so I did the big unboxing yesterday.

Here are some quick videos to show you what we came up with in just one arvo.
Lots of variation. I think its a great synth and a good way to begin your journey if you are new to video synths.
Even if you have a big LZX system, I think this is still useful as its size makes it perfect for live gigs.

ARSEq - NLC - Build notes

These are my build notes for the ARSEq. It's a Nonlinearcircuits module in Eurorack format.
 ARSEq ( =Attack Release SEquencer). Its a hybrid sequencer and AR envelope generator.

The thing that makes this special and unique is that the envelope needs 2 clock signals to work.. one to start the attack and the next to start the release.
There are 4 clocked envelopes.


NLC words of wisdom.








--------------------
When installing the pots, you will need to decide how snappy you want the envelopes to be,
Andrew suggests the best setup is
100k pots for Attack and 1MA pots for Release.
The 100K pots are type B, linear taper.
jACKS , LEDs and pots.
The underside.
Nice one andrew

Divide & Conquer - NLC - Build notes.

These are my build notes for the Nonlinearcircuits eurorack Divide & conquer module.
Obviously this is a clock divider.

4 different dividers:
1. /2, /4, /8, /16, /32, /64, /128, /256
2. /1.5, /3
3. /2.5, /5
4. /3.5, /7
 Its super flexible as you can patch outputs into inputs to get crazy divisions.

 Some NLC words of wisdom
Broke Down Engine and Other Troubles with Machines. This is a book by Ron Goulart.
 "Thirteen wry and terrifying tales of homo mechanicus (what we are becoming) versus the machines we have created." 1971.
I haven't read this, but it sounds a bit like The Terminator.
La Grande Bouffe is a 1973 French–Italian film directed by Marco Ferreri. "The film centers on a group of friends who plan to eat themselves to death. It satirizes consumerism and the decadence of the bourgeoisie." Wikipedia.

 ======================
Back to the build.
The CMOS chips you will need are: 4013, 4024, 4070.
They are all SOIC format.

CD 4024


The second from the left is the CD4070

I don't have any 4013s so I've ordered these:
Mouser No:
Mfr. No:CD4013BM96G4
Mfr.:Texas Instruments
Flip-Flops CMOS Dual D-Type Flip Flop
----------------------------------------------------------------------

I used 810 Ohm resistors for the LED resistors.

I ended up using these.

These rectifiers are for protection only .. against plugging the module in backwards.

If you are building lots of the NLC modules, buy these diodes in bulk. Andrew uses these in almost every project.


Soldering the headers.

I use standard 40pin male/female headers. The are cheap as chips on ebay. Cut them to size.

Jacks

The LEDs before soldering. Solder them only after you have secured the panel.
Ready to put it all together




Yes it lights up like a Christmas tree. That's a good sign.

Sly Grogan - NLC - Build notes

These are my build notes for the nonlinearcircuits Sly Grogan.
Its a envelope generator Eurorack module based on a design in Electronotes #86.

Some pick of the virgin PCB & panel

Get those ICs on first.

-------------------------------------
On Order:
Mouser No:
Mfr. No:
BZX79B2V7
Mfr.: Taiwan Semiconductor
Zener Diodes 2.7 Volt
 ----------------------------------

 The SMD version of the 4148
 Almost there, just waiting on some parts.
 Japanese slang term meaning "butt poke".

While waiting for those components do contemplate the ancient Japanese Art of Kancho.

The 2.7 V zener diode

The 100k trimmer







I used a 820 ohm resistor for the LED resistor. -----------------------------------------
