Is the John Chowning Reverberator not a part of the STK? And can it perhaps
be encapsulated like the STK opcodes?

Same goes for JCRev, you can easily make one using Csound opcodes 
(alpass, comb + delays).

Hello,

You can do what you want with Csound, but in the case of Chowning's reverb,
using Music 10, fomulas are not the same: REV2 and REV1 require a gain
factor and a delay, whereas alpass and comb compute the gain factor from a
logarithmic formula involving delay and loop-time.

About Risset and Chowning's works (and all pioneers of sound synthesis), you
can read my book "Pionniers de la musique numérique", Delatour France, 2012.
There is notably a correct translation in Csound of the beginning of the
famous Risset's work "Mutation", and all references (and attempts of
translations) about Chowning and Risset's works.

Best,

Olivier Baudouin, PhD.

Hi Olivier,

Fascinating details, thanks.

Are there any plans to translate your work into English?

Cheers,
Andrés

Hello Andrés,

A translation would be very hard to realize... so not for the moment but perhaps one day?

English quotations have been kept in footnotes.

Thanks for your interest.

Olivier.

My wife reads French, but doesn't do computer music. I do computer
music, but don't read French! If there was ever a case for the Vulcan
mind meld, this is it.

Much of Risset's work is in Dodge and Jerse _Computer Music_, and
Risset's _Introductory Catalogue of Computer Synthesized Sounds_, from
1969, is reprinted in its entirety in the booklet that comes with the
Wergo CD: The Historical CD of Digital Sound Synthesis. It's pretty
easy to make Csound instruments based on the info in these sources.

Yes, the "Wergo CD: The Historical CD of Digital Sound Synthesis" is a very good source. But I have found mistakes in some Music V codes... that is in my book!

Best,

Olivier.
