A review by Enrico Cosimi

To be On, to be OFF, that’s the SWITCH – una lezione di Roland Kuit

After being in Rome, last autumn, for an intensive seminar on virtual modular synthesis, Roland Kuit decided to publish – for an almost symbolic price – the content of his lecture by placing it at the disposal of those who feel ready to face the complexities of unconventional programming.

By Enrico Cosimi

Although the topic may seem exhausted in a matter of minutes, thanks to his formative experience at the Institute for Sonology Utrecht--where, we recall, was one of the first resident event generators, the result of the genius of Stan Tempelaars – allowed an approach and an absolutely unconventional setting, both in tone generation, as in the construction of complex structures.

Modular synthesis, Logic

Without going too much into details, we anticipate that the density and expertise poured in the text are absolutely worth the few euros required to purchase; we can list a few programming and finesses demonstrated by Kuit:

* Switching from raising events to design sound structures;
* The articulation, event after event, switch after switch, control mechanisms that enable functional tonal variation in the instrument;
* The use of a simple event generator as the switch for the construction, along with programmable delay lines of low-level oscillators (i.e., lightweight impact on CPU);
* Treatment applied to an audio signal - internal or external - achieved through switching on and off of the individual bits of the AD and DA converters available on the Clavia NMG2
  (from this point of view, you can put your OTO Biscuit to the attic.....;)
* The production of fierce sound treatments obtainable through numerical signal through rearrangement.

All this, through conscious and stylish use of simple structures concentrated around the on/off switch.

As with other educational texts produced by Kuit, again from a PDF with the patches ready to auto-loading in the Clavia Nord Modular G2 Demo Editor: apart from Safari, any browser 2.0 can open the PDF – or its html version – and to ensure, with a simple click, the reading and listening in real time of the patches.
The text contains all information necessary to the proper functioning of the mechanism and, as you can imagine, is a real mine of programming tips also applies in other contexts.

Review by Michael Ed
"Finished exploring ON/OFF. Tough and demanding!
Using the Stage 2 is like mixing existing chemicals, results are often predictable ... tweaking the Lead 2X is like focusing more on the molecular level, but you almost can "see" what's going... on ... but ON/OFF-ing is like going down to sub atomic level, like quantum mechanics, you experience new stuff, impossible according to classic Newtonian physics, but feasible anyhow, doing things that "can't be done" ... strange and fascinating!"
