Pulse/Frequency Division With a Sequencer – Serge Synthesizer Tutorial

April 23, 2014 · Posted in Uncategorized · Comments Off on Pulse/Frequency Division With a Sequencer – Serge Synthesizer Tutorial 

Use a sequencer to create polyrhythms and pitch divisions.

Though this is illustrated on a Serge the concepts apply to many modular synthesizers. Let me know how you apply this on your modular synthesizer.

Serge From Melodic to Krellodic

November 22, 2013 · Posted in Uncategorized · Comments Off on Serge From Melodic to Krellodic 

‘djangosfire’ has been experimenting with a semi-diatonic TKB patch on the Serge, details below:

Thought of a pretty weird idea:

– take the “KV” voltage out and patch it into the scaleable inputs of 2x VCO’s.
– scale the VCO inputs so that you have a semi-diatonic octave.
– THEN add a single row CV out from the TKB (I used row A)… patch it to the 2x VCO’s
– tune each step of row A out to bring the sum of the KV output CV to = a more accurate diatonic step.

Also, by patching the TKB “Reset” to different stage inputs … I created sub loop sequences that have a pretty, kind of doppler tuned sound…. since when you are not holding a stage pad, the TKB is transmitting ONLY the scaled KV output.

I need to fully notate this one.

And finally, I wanted to make a quick improv video that shows how easy it is to take a pretty sound into chaos…….. “Krellodic” AKA melodic Krell :)

Thanks for listening!

Serge Modular Sounds 10

Background video description:

The WAD was in a very sedate mood today, so I used it as a standard rhythmic delay. Delay A to out (center), delay B to the Frequency shifter with Up and Down outs panned hard left and right.

Modular synthesizers: Serge Creature TGO Demo

May 13, 2013 · Posted in Uncategorized · Comments Off on Modular synthesizers: Serge Creature TGO Demo 

As there didn’t seem to be too many basic demo’s of Serge modulars, ‘pjoris2’ tries here to document his discoveries of Serge. He’ll start with the most recommended “starter” M-class pannel: the Creature; and more specifically with the basic noisemaker in there: the Voltage-Controlled Timegen Oscillator (TGO). All noises are made with +/- only the TGO. X-Fader used as output, and sometimes the SSG als LFO. An overview of the video:

Basic Functions of the Left Oscillator (Osc 1)
(00:05) Saw wave output
(00:20) Square wave output
(00:30) Frequency modulation using variable CV input
(01:10) Audio-rate frequency modulation
(02:00) 1V/Oct CV input
Basic Functions of the Right Oscillator (Osc 2)
Trigger on (to the right)
(02:15) Triangular wave output with variable rise and fall
(03:00) Frequency modulation using variable CV input
(03:30) Pulse output, varying frequency and duty cycle
(04:30) Demonstrating trigger switch
Trigger off (to the left)
(04:45) Triggering Osc 2 with pulse out of Osc 1
(05:00) Depending on the relative settings of Osc 1 & 2, the frequency of Osc 2 is now controlled by Osc 1. We can vary now Rise & Fall without changing the pitch of the Osc 2 output.
(05:40) Now using the Pulse output of Osc 2: pulse width modulation.
Using Right Section as Filter
(06:00) Plug in saw of Osc 1 in the lower Sig In (black jack). The Rise pot changes filter cutoff. The Fall pot only makes signal more quiet.
(06:30) Filter cut-off modulation using the VC in of Osc 2.
(07:30) Audio-rate filter cut-off modulation
Saw of Osc 1 in Input of Osc 2 and Trigger On
(08:00) Filtering was with Trigger Off. Now see what happens with Trigger On for Osc 2. No idea what it does, but sounds interesting …
(08:40) Adding frequency modulation of Osc 2.
Feedback on Osc 2
(10:00) Feedback the output in the CV In: that way you get exponential (+ modulation) and logarithmic (- modulation) slopes
(11:00) Feedback of the output in the Sig In. No idea what this is.
(11:30) Add an LFO to the CV in. Even more noise.
(12:00) Certainly if you take the modulation into audio frequencies !
And finally: some more feedback:
(12:45) Osc 1 out in Osc 2 Sig In, Osc 1 Pulse in Osc 2 Gate in, LFO in Osc 2 CV in.

Serge TKB Controlling Oberheim SEM and Moog Voyager

September 1, 2012 · Posted in Uncategorized · Comments Off on Serge TKB Controlling Oberheim SEM and Moog Voyager 

Routing separate sequences to separate analog synthesizers in different formats the Serge tkb oversees all control voltage tracking tasks. These sounds were created and tweaked live.

Additional info about the Serge:

A few words about Serge sequencers. Note that Serge/Sound Transform does not make a traditional keyboard like you see on most other synthesizers, such as Moog, Roland, etc. You can get a traditional vintage control voltage keyboard (Roland, Moog, Polyfusion, etc.) and interface it to the Serge, since the Serge adheres to the 1 volt/octave standard. Or you can generate a control voltage from your MIDI keyboard and an interface.

Sound Transform follows the Buchla model of offering a touch sensitive keyboard/sequencer unit, as well as more traditional simple sequencers. Originally, they offered a sequencer whose stage was selected by push buttons. This is what’s called a sequencer-programmer: you could use it in an automatic mode as a traditional sequencer, or use it manually to select/program voltages you set. So you can mimic a traditional keyboard if you want by tuning each stage to various notes. Or discard the traditional keyboard concept and simply use it to fine-tune different parameters in your patch for later recall.

The TKB is the hub of the sequencers – each stage has a corresponding output that goes high when it’s selected. This complements the other sequencers, which have an input that, when high, causes that stage to be selected. So the TKB can be used to control another sequencer, or whole sets of other sequencers, regardless of the number of stages they might have.

Sound Transform offers a set of Serge sequencing programmers, from four to eight stages, plus the Sequencer with eight stages, and the TKB with sixteen stages. Confused? What they call their regular Sequencer is not a sequencing programmer in that each stage is selectable by a button but not by a stage select input. The sequencing programmers have stage select inputs. And the TKB has stage select outputs.

The sequencers are a little ‘bare’ in that none of them have an internal clock. You must use another module as a clock source, and typical sources are the DSG, DTG, and the Smooth section of the SSG, patched to oscillate. But they do have cute features such as step trigger inputs for RESET, UP/DOWN, and HOLD.

Most of the Serge sequencers are optionally available with an internal connection to a quantizer. Why would you want that? The quantizer forces the range of the stage pots into stepwise note intervals. So as you turn the pot, it isn’t a continuous rise or fall, but steps up and down a scale. This makes tuning much easier and more reliable. The variable outputs are still available on quantized sequencers also.

Here’s a new video featuring a Serge modular:

“This was the first sounds made on my system. Recorded 10 minutes after plugging it in. I have no idea what is going on, but it sounds nice.”
