Just arrived

Just arrived: prototype board and panel for a modular trigger to DINsync module. This one got so dense, i had to place a 74HC125 on the Backside of that board. But – finally – i had the opportunity to sneak in the first chip i ever used some 37 years ago, the glorious 7400 in a design. BTW its the proof in former times everthing was bigger; back then it was a DIP, now its SOIC. Big plus for this one: theres is no firmware do write.

Size does matter

Size does matter, indeed.

Thats what i routed for an upcoming project. Can you spot the tiny IC labeled 74HCT1G126?

On the Screen it looket quite feasible, maybe because i’ve got a big screen. But i got nightmares as the part got delivered.

See below:

What i did at the Weekend

Who doesnt loooove blinking LEDs on a Module?

I got some WS2812bto evaluate and what can i say – i love the idea having every LED as full color RGB, saving loads of PINs on the Teensy and make routing much easier. Just to proove the routing theory i redesigned an upcoming module to take advantage.

Brackdraft is you will have to solder some more SMT parts and possibly glue lightpipes. But hey – its full color!

Godfried’s Turing Sequencer

Godfried Alan Tourissaint

I couldn’t resist. I thought it would be nice – besides generating CVs and quantized Notes – having a Turing Sequencer at hand as an option for Godfrieds CV-Track.

Then it somehow got out of control, at least a bit, and it came out like this:

  • Shift Register with configurable length up to 32 Bits, content is lockable
  • DAC Register with configurable length up to 12 Bits
  • CV Output 0-5V independant of the DACs Register length
  • Polyrhthmic – as everything else
  • everything including the Shift Registers content is saved with Godfrieds Snapshot

Thinking about, maybe i should add an Direction Feature, so you can choose shifting the Shift Register either left to right or the other way round?

What do you think?

Triples

Triples is a labour of Love. Starting 2013 with the RED LFO, Triples has a long list of Ancestors. It is the first module i ever did with an Microcontroller, and there always was something lacking. At least to my taste.

Finally with the 5th incarnation it is where i intended id to be.

Check out the Manual to see what its all about

Now its getting serious: i migrated the old Blog to a more or less full Blown Site with its own URL.

Besides learning the WordPress way of doing things i also finished a longtime Project, that started 2013 with the Red LFO:

Triples

Triples is finished and im quite satisfied the way it turned out. Full Kits will be available in February, if you like you can preoder now.

As you might have noticed theres a lack of photos for now. So i’ll leave now to make some…

Godfried’s Algebraic Clock Generator

One of Godfrieds track types is being a clock generator thus generate periodic trigger pulses somehow dependant to the master clock. You got it, “Clock Divider” or “Clock Multiplier”

The classic Clock Divider divides a master clock by a given number, mostly a perceived musically usefull. So it generates a trigger every 2, 4, 8…etc master clock beats, some do even weired things like uneven numbers. Similar goes for Clock Multipliers that mostly generate 2, 4, 8… etc evenly spaced triggers for one beat of the master clock.

But what about Polyrhythms, which means uneven or even prime fractions off the classic musical timing, thats based on powers of 2 ( if you don’t to evil things like triplets ) ?

So here is what Godfried does, you might want need to remember some basic algebra from way back in school.

Godfried doesn’t differntiate between Divider and Multiplier, it uses an Algebraic Clock Generator, that calculates the tracks clock in respect to the internal master clock (the one that you set by the Tempo parameter in the Clock Menu).

It generates a Trigger pulse every n counts of a fraction of the master clocks beat by using “Counts” and “Fraction” parameters (numerator and denominator mathematically speaking).

Here are some examples:

Counts = 4, Fraction=1 generates a trigger every 4 beats of the master clock – a classic Clock Divider

Counts = 1, Fraction= 4 generates 4 triggers for every single beat of the master clock – a classic Clock Multiplier

Counts=7, Fraction=2 generates a trigger pulse every 3.5 beats of the master clock – not sooo classic anymore….

Counts=13, Fraction=7 generates a trigger pulse every 13/7 beats of the master clock, that is a 0,4642th note given a 4/4 bar on the master clock which means a trigger every 0,9285s with a master tempo of 120.00 bpm. No sign of classicness anymore, huh? Instead severe Polyrhythmitistm.

Please note, that the Fraction parameter goes all the way up to 32, so it divides a beat of the master clock into 32 slices – thats a 128th note if you consider a 4/4 bar. Please further note, that Counts=4 and Fraction=8 is the same as Counts=1 and Fraction=2. And so on, remember?

Since a digital clock is always quantized rounding errors might occur. And since i know you clever modularists will do self playing patches, that last forever and these tiny weeny fractions will add up after some days rendering your art offbeat – whatever offbeat means in polyrhythms – these are as evenly distributed as possible to the single steps (Counts).
