Lange Anna - ST Modular

 These are my build notes for the Lange Anna.
 

 
It's 84HP long.


 
Its basically  a mult  for distributing cv and audio...like the one on the Makenoise skiff.
There are 3 channels. 
Each channel has a pot to set polarity.
Each channel has 1 input and 4 outputs.
Each output has LEDs to indicate polarity
If nothing is connected to an input of a particular channel, its outputs will supply either 10V or 5V (there is a switch to set this).

Some details from the ST modular website:

The BOM is here

You can find files for the rest of ST Modular's modules here:
 

Most of the parts are pretty standard.
Op-amps :
4X TL072
3 X TL074 


There are 24 SMD LEDs
All 0805 size
* It´s best to use different SMD LED colours per channel,
e.g. circle = white, square = orange, triangle = green
 
I guess this means 8 of each.
I ended up just using 1 colour.

Time to solder the LEDs
They are polarised of course.

 
Most often you can not see any of the LED markings.
They are super small. I use a microscope or the zoom function of my mobile phone.
A small notch or dot will usually indicate the cathode side of an led. 
This also goes for markings on a board too.

 
Note, I've read the opposite to this on some sites... so check the supplier data sheets
before soldering

The LED Ive purchased is this:
630-hsml-c170-t0000
This is a screen shot from it's data sheet:
And surprise ---- the notch points to the anode ????
Confusing 



If you look closely, you can see a small dot (top view) indicating the anode (according to the data sheet.
Looking from the bottom, there is a T shaped line with the middle pointing to the anode.

 I thought there must be a mistake with the data sheet.
But as it turned out in this case the dot does point to the anode,

STOCHASTIC sequencers

 I've been coming  across a few STOCHASTIC sequencers recently.

The other day a friend showed up with a Oxi One

This has many more modes other than Stochastic, but I found that mode really interesting.

So what are Stochastic patterns?

These are patterns that are generated randomly, allowing for endless generative ideas in music production. These patterns can be used to create unique melodies, rhythms and structures in music.
There are quite a few systems and sequencers, eurorack modules that embrace this idea, and the list is growing.
I think we should embrace these new tools.
so musicians can explore new soundscapes and create unique compositions that would otherwise be impossible to achieve.


This is a eurorack module from Stochastic Instruments.

Below is the O-Blek
Its a MaxforLive stochastic sequencer with individual length options to offset and produce dynamic ever- changing patterns easily in Ableton Live.


Another Eurorack module which uses Stochastic ideas is Vermona's Melodicer

The two primary modes are dice and real-time.
- dice mode creates a melody and holds it until a new rhythm or melody is seeded into memory.
- real-time mode continuously generates random patterns based on the current settings.

The 12 sliders each have an associated note, and turning up that slider will increase the 
probability that the corresponding note will be played. 
Note value sets the clock division from whole to 32nd notes.

This sequencer uses cycling '74


Radioaktivnost is a 16 step sequencer for software and hardware which is clocked by radioactive decay.
How cool !!

These are just a few examples Ive found using a quick google search.
Im sure there are many more.

So in summary the Stochastic sequencer isn't your standard sequencer.
It doesn’t repeat itself and you don’t program fixed steps for variation.
Instead you duet with it by starting with the fundamental musical settings such as  pitch, 
duration, octave and various transition events. 
By changing the basic probability of these settings the melody will evolve.

I think Stochastic patterns allow for a level of creativity that is unprecedented in music production. 

By leveraging the power of randomness, musicians can explore a variety of musical ideas and find inspiration for their own compositions. With this approach, musicians can also create compositions with an ever-evolving structure - making sure that no two performances are ever the same!

Kos- Greece Part 1

 Some pics of the Island of Kos, in Greece.
Part 2 is here:
   - Kos - Greece - part2


Kos is a Greek island located in the Aegean Sea, near the coast of Turkey. It is part of the Dodecanese island chain and has a population of approximately 33,000 people.





..






The island has a rich history, with evidence of human habitation dating back to prehistoric times. Kos was an important center of learning in ancient Greece, home to the famous physician Hippocrates, the founder of the Hippocratic School of Medicine.



Kos is known for its beautiful beaches, crystal-clear waters, and picturesque landscapes. Its mild Mediterranean climate makes it a popular destination for tourists throughout the year








Today, visitors to Kos can explore many ancient ruins and historical sites, including the ancient agora (marketplace), the Castle of the Knights of St. John, and the Asklepieion, a temple dedicated to the god of healing.




The Castle of the Knights of St. John, also known as the Castle of Neratzia, is a medieval fortress located in the port town of Kos on the island of Kos, Greece. The castle was built by the Knights of St. John, also known as the Knights Hospitaller, in the early 14th century.



The castle was constructed to protect the town and the island from attacks by the Ottoman Empire and other enemies. It is located on a small island connected to the mainland by a stone bridge, which was built in the 1930s.



The castle has a rectangular shape and is surrounded by a moat. It features several towers, including the Tower of the Great Master, which was the tallest tower in the castle and provided a vantage point for defending against attacks.



Today, the Castle of the Knights of St. John is a popular tourist attraction and is open to visitors. It has been partially restored and visitors can explore the castle's walls, towers, and other features, including a small chapel and a museum dedicated to the castle's history. The castle also offers stunning views of the surrounding sea and town of Kos.

Temps Utile - basic (micro temps)

 When you power the module up you will enter the global input configuration.

Using a micro temps here

To reach the Main (channel) page 
1. long press the right encoder.
2. scroll to the saved setting you want to recall using the right encoder. 
    (in this case 6 clocks)
3. press the right encoder.


To set the BPM 
1. press the left (up button once)
2. turn the right encoder to adjust the BPM
