Dan Simmons - Hyperion - introduction

Hyperion by Dan Simmons was published in 1989.

It has won Hugo (1990) & Locus awards, but  never received the attention of books like Herbert's "Dune" or  Asimov's "Foundation". 

Rumors are that it will soon be a movie.
Maybe this will give it the attention it deserves.

There are 4 books in the series:
Hyperion, Fall of Hyperion, Endymion, Rise of Endymion.

The structure of the novel and it's influences are interesting.
It's composed of a series of tales told by a group of 7 travelers .. kind of like Chaucer's "Cantebury Tales" and Boccaccio's "Decameron".
The title, Hyperion is taken from one of John Keat's (unfinished) poems "Hyperion" which used as a source, the Titan wars of Greek Mythology. 
The poet Keat's is really important. It's the name of one of the cities of the planet Hyperion and the second book "Fall of H" is a series of dreams of the poet.




There are 6 tales in the novel.
1. The Priest's tale
2. The Solder's tale
3. The Poet's tale.
4. The Scholar's tale
5. The Detective's tale.
6. The Consul's tale.

These travelers relate their interlocking tales while on a pilgrimage organized by the "Church of the final atonement" to the Time Tombs of Hyperion.
Each story relates to the the planet Hyperion and gives the opportunity to tell who they are and build
the Simmon's universe.
Their journey takes them to the evil creature known as the "Shrike".... The Lord of Pain.
Each pilgrim has their own unique reason for the journey and they all suspect they will probably never return.

The pilgrims are:
1. Father Lenar Hoyt - a Catholic Priest.
2. The Martian soldier Colonel Fedmahn Kassad (of Palestinian descent).
3. The poet Martin Silenus who was born on Earth (and wrote a book about Earth before it was destroyed).
4. Sol Weintraub, a Jewish professor, with his infant daughter Rachel.
5. The detective Brawne Lamia.
6. The Consul, Merin Aspic.
 
The story is set in the 29th  century.
Old Earth has been destroyed, and humanity has colonized the stars forming the "Hegemony of Man".
Mankind  is allied with the Technocore AIs. This alliance is not all that it seems and I suspect The Technocore doesn't have Mankind's best interests at heart.
The Technocore manages the "All Thing"  ...the connection between all humans. Through this connection, humans can vote on legislation, communicate with each other, and access information instantaneously......reminds me of the internet. Remember, this book was published in 1989.

On the extremity of "Colonized Space" live the "Ousters". These are modified humans (who are at war with the Hegemony of Man).

Clocking the Buchla 252e (with a 225e)

 
 The Buchla 252e has no midi or analog clock input as it was designed to be THE master clock.
 

 The 252e manual says it supports MIDI clock, sync receive and sync transmit.
Transmit is straightforward, but syncing and receiving MIDI from something like a DAW,
needs a module like a 225e.
There may be other modules which could do the same job but I think the 225e module is a great pairing for the 252e. They communicate with each other using i2c.
 
The 225e has 16 busses, but the last 6
are impt in syncing things. These are busses J to P.

These handle controller and clock messages. They are translated into 0-10V CVs

Each controller Bus is divided into 2 groups: (a) or (b).....(two controllers for each of six busses).

Controller output bus P(b) is actually not a controller, but is a dedicated MIDI Clock output.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If Channel is set to “Clock” (after 16 and before 0) a different interface is displayed:
 


The Div fields allow the 225e to generate 10 volt pulses based on rhythmic divisions of an incoming MIDI clock. The numerator represents a count; valid values are 1-8. The denominator represents a note length.

1: Whole note                                                     8: Eighth note
2: Half note                                                        12: Eighth note triplet
3: Half note triplet                                               16: Sixteenth note
4: Quarter note                                                   24: Sixteenth note triplet
6: Quarter note triplet                                          32: Thirty-second note
 
 
Str = Sync Transmit
Src = Sync Receive


So if you wish the 252e to receive and be controlled by external midi clock follow these steps:
1. On the 252e, press and hold the Master BPM knob until the display reads Off.
2. Turn the Master BPM knob on the 252e until it reads Src (Sync receive).


 ----------------------------------
 
If you are trying to clock a larger modular system from the 252e  (without a 225e) use Cell1 output.
This will supply a pulse every time  the cells return to step 1.
 

Use a clock multiplier like the  Northern Light Modular 2TT.
Set an output to be a multiple of 2, 4, 8, 16 etc and you have a master clock while retaining the pulse outs.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

You can also use the 256e  as a clock multiplier
 Buchla Quad voltage processor

















You can of course  use any of the pulse outputs on the 252e as a clock.

Personally, I just think the 225e is the easiest module to use. It allows you to add a midi clock input
to the 252e, is a perfect and flexible clock multiplier/divider and is a preset manager to boot.



Here, bus P is supplying the clock.

P(b) is your unmodified clock.

P(a) is the clock multiplied by 2.



























I'm using abelton as the clock source.


Remember to set it up to transmit midi.

ToneGym Chord Progression Generator

 This looks like a useful site.
And it's free too.
 

 

Is learning music theory going you make you less creative as an artist?
I don't think so.
The more tools and knowledge you possess, the better I feel.

Night Owl Patch

This will be released on my 3rd album - Pursuit of Harmony.

 TRIGGER out of the DFAM ----> Clock in from the SUB H 
This is the sync. The DFAM is master.

This is a interesting patch as adjusting the VCA envelopes on either synth will
have an effect on the other synth.
DFAM VCA EG Out to Subharmonicon Cutoff In
DFAM Pitch out to Sub VCA in 
 
The Trigger from the DFAM effects the PWM of VCO1

Helvetica Scenario - NLC - Build notes - part 2


 These are part 2 of my build of the Non Linear Circuits Helvetica Scenario module.
Part 1 is here:

Its a dual sample & hold module.

The module has a slew circuit added to each channel.

Andrew  has I think used the Buchla SOU for some inspiration.
the Buchla 265 Source of Uncertainty uses as a source,
white noise and a 100Hz oscillator
 
 
 
 
 
This module instead contains a simple jerk chaos circuit running at approx.
300Hz to supply a signal for sampling. 
 
Well what actually is the Helvetica Scenario ??? 
It's all about the calcium molecule

"The calcium molecule contains a triple helix and is based on a semi-permanent structure of four electrons supporting three protons. The protons feed electrical information to the central queen atom, which is vital to the structure of the molecule. Without the queen atom at the centre, the entire structure would collapse causing the Helvetica Scenario."  :-(

Oh my God. Sounds like we are all going to die.

Watch the video to learn more about this dangerous condition:


 
Hopefully, after watching this you will have realised its all a joke.
Your teeth aren't going to fall out , and your bones won't crumble to dust. :-)
 
-----------------------------------
 
 Getting back to the build.
The module uses 3 LEDs
One LED (3mm or 5mm) is for the chaos circuit.
Andrew recommends blue.

The other two LEDs are bipolar indicators that you will see on the front panel
Ive been waiting for some bipolar LEDs to arrive.
 
 These are Red/Blue
Finally. they are here.
If using red/green from Tayda, 1k is ok. 
If using red/blue, probably 4k7 is best.



If using factory vactrols , maybe try 1k for RL.
 
I'm also going to build my own vactrols.
So I Used  4.7k for the RL resistors



 
I'm trying some GL5549s with some yellow LEDs  

Some info about vactrols:


The 1M* at the base of the vactrols set the maximum slew rate, feel free to leave them off or change to suit your needs (lower resistance = less slew). If not sure, just install 1M for now.


Do the headers next.
 
 
These join the two PCBs
 

B100k - linear pots

Jacks


OK ... all done.

The blue LED... part of the chaos circuit

Dustwork - self tuning VCO

Some build notes for the Dustwork VCO.
The  official website is here:
 
And the build guide
 
A super easy build since most of the SMD components are already installed
All parts supplied.
 
This is version 2
Its 6HP
A VCO that can tune itself. Imagine  !!!
 



Just 1 PCB
 
 
The way it works is simple. Send it a ‘C’ note over a 1v/oct CV signal, hit the button and the module will do the rest. It will calculate the offset voltage needed to bring that C up to perfect pitch. It’s recommended (as with any analogue synth) to let the module warm up for 10 minutes or so before tuning up.
 
 
The AS3340 chip is Alfa's modern equivalent of the famous CEM3340 voltage-controlled oscillator. It provides Ramp, Pulse/Square, and Triangle outputs, has inputs for oscillator sync, is temperature compensated and stable, and provides excellent 1V/Oct tracking.
 

Look for the bevel on one side of the chip to help orientation.
The bevel is the same side as the dot on the PCB.

For more info

Next add a 300k resistor between pins 15 & 16 of the AS3340 chip
 


2x 10K trimpots
 

The two headers.
A 6 pin and 10 pin.
 

The 10 pin is of course the power supply.
the 6 pin is used in programming


The 3 pots.
they are all B100k
These go on the other side of the PCB
 


two 3.5mm socket jacks

the push button switch


and the LED
short lead = flat side = cathode
 

it’s time to program the module. For this,
you’ll need the USB Tiny programmer, along with AVRDUDESS programming app which you
can find online. 
 
  you need to download the latest firmware (it’s a .hex file) on the product
page on Duskwork.net
 
To be continued....

Moog Mother 32 & DFAM Jam # 1

..

 This will be released on my 3rd album - Pursuit of Harmony.

Some patch notes
The Politics of Trust
I clocked everything to abelton using a touchprone MIDI to Clock converter
The sync:
DFAM Trigger out ----> M32 Tempo in.
This really speeds things up.
 
Another way to sync is:
DFAM Trigger out ----> M32 RUN / STOP in

M-32 & DFAM acid patches

Some New Years Day patching.
Ive been planning to play around with these puppies for ages and never quite had the time.
I guess lockdowns have a few advantages

The Moog Mother 32 and DFAM sound great together. I love acid sounds and its one of the first things I seem to gravitate to whenever I play with a new synth.

Though Moog use transistor filters in comparison to Roland's diode ladder filters, I think they still 
make for good 303 imitations and add a slightly different feel to the acid sounds we love.

Below are a few different patches to try out.
Of course these are just starting off points.
Working through some of these patches is a great way to learn how to use these synths
Actually, I still prefer the acid sound I get from the DFAM, but these are also pretty good. 
https://djjondent.blogspot.com/2021/12/dfam-moog-acidish-baseline.html

The addition of a mother 32 to the setup means its really easy to clock this (using MIDI) from a DAW such as Abelton. 
--------------------------------------------

This first patch combines "Tribal Drums" with the "Classic Acid bass" patch.
 
Patch the gate out from M32 to Clock/adv of Dfam (red)    This is how you sync these two machines.
The M32 is the master. 
 
 This next one is the "Acid is the way patch". from the studio bundle.
 
1. Patch the gate out from M32 to Clock/adv of Dfam (red)
    This is how you sync these two machines.
2. Assign (M32) ---> mult (M32) (orange)
 3. Mult 2 ---> VCmix Ctrl (green)
4. Mult 1 --->  LFO rate (purple)
Thus, the signal from the assign out controls both the mixer and the LFO rate.
 The assign out jack is really impt in this patch.
 This is as the name suggests an assignable output, who's function is programmed in setup mode.
It can be anything from clocks, random voltage steps, triggers, to MIDI CC

5. EG ----> mix 2 (yellow)
   Mix 1 & mix2 are inputs to a voltage controlled mixer.
   Thus, the M32’s VC mix is used as a VCA. It controls the amplitude of M32’s envelope.
6. VCF Mix ---> VCF cutoff (blue)

7. VCO Saw Out ----> Ext. Audio In. (pink)
whenever a cable is plugged into this jack, it overides the noise to this jack (clockwise position on the M32s main mixer. Thus in this case, a sawtooth wave replaces the noise source on M32’s mix knob. 
 
8. M32 LFO Tri Out -----> M32 Mix CV In. (red)
Thus M32’s triangle LFO controls the mix knob. 
 
9. M32 LFO Square Out ----> DFAM 1-2 FM Amt input. (green)
 Thus M32’s square LFO controls the FM depth on the DFAM. 
 
10. DFAM Pitch Out to DFAM Noise Level In. (dark red)
This will make DFAM’s pitch sequencer control the noise level of DFAM.
 
11. DFAM VCF EG Out to Mother-32 VCF Res In. (pink)
This will make DFAM’s VCF envelope control the resonance level of Mother-32’s VCF. 
 
------------------------
 
This last one combines the Da Funk Patch with my variation of the big bottom Bass patch.
The original BBB patch set the seq pitch mod switch to off, which disabled the top sequencer.
The VCF mod knob amt is impt.
The vcf mod polarity of the m32 can be both -ve or positive, but +ve is better
(i have it marked -ve in the pic)
And both square & saw sound good on the m32.
 


The gate from the M32 needs to be multed. One copy patched to the clock input of the DFAM
and another to the VCA CV input of the M32
