How to rewrite example from book that uses omn-dictum

[jon]

Greetings,

 

I've been working my way through the "Fundamentals of Composition with Opusmodus" book since my copy arrived on Monday. It's been a great help adjusting my brain from OpenMusic to Opusmodus. I'm currently working through section "2.4.2.5 Rhythm 5."  In the code on page 92, there are a series of 8 lines that use "omn-dictum" to change all the pitches for each of the previously-generated rhythms to the correct general-midi pitches for the non-pitched percussion sounds (bass drum, bongos, congas, etc.). For example:

(setf bass-drum (omn-dictum '(:all b1) rhythm1))
(setf low-wood-block (omn-dictum '(:all f5) rhythm2))

 

I found release notes indicating "dictum" had replaced omn-dictum, so I attempted to use "dictum" in its place. My attempted version of those same two lines:

(setf bass-drum (dictum '(:apply b1) rhythm1))
(setf low-wood-block (dictum '(:apply f5) rhythm2))

 

results in all notes and rests being changed to b1 or f5, not just the notes/chords. Is the use of an all-encompassing ":range" the only way to target all of the pitches, separate from the rests? I was able to get it to work like this:

(setf bass-drum (dictum '(:range (c3 c6) :apply b1) rhythm1))
(setf low-wood-block (dictum '(:range (c3 c6) :apply f5) rhythm2))

 

but I was hoping there would a way to either ignore rests or do something like "(:any :pitches)". Is there another way of targeting just any/all pitches?

 

Thank you,

Yes, the function name has change, the next edition will fix this.

Please give me an example with input and output (what you are looking for) and I will see what I can do.

 

(setf omn '(q c4 - d4 - e4 - f4 -))

(dictum '(:apply b1) omn)
=> (q b1 mf b1 b1 b1 b1 b1 b1 b1)

you looking for:
(q b1 mf - b1 - b1 - b1 -)

here it is:
(dictum '(:range (c1 c8) :apply b1) omn)

Thank you @opmo. The second example is what matches the output in the book (where the rests are retained). I'll keep that in mind for future use.

 

Incidentally, is there a forum for posting errata for the book? There's at least one example in the English version of the book where a function is using an Italian name, rather than the English name.

Thank you @jon.

Please send me an personal post on any typos etc... you find in the Book 1.

P.S. There are two more books in making. One by Julio Herrlein and one by Fabio De Sanctis De Benedictis.

Looking forward to see the new books !

 

All the best !
