clumo

lumo and csound <3 clumo

Clumo is a patched version of Lumo for Csound Score pre-processor.

How to use

<CsoundSynthesizer>
<CsOptions>
</CsOptions>
<CsInstruments>
 
sr = 44100
ksmps = 32
nchnls = 2
0dbfs = 1.0
 
 
instr 1
  out poscil(0.1, p4)
endin
 
</CsInstruments>
<CsScore bin="clumo">
(require '[clojure.string :as string])
(require '[goog.string :as gstring])
(require 'goog.string.format)
 
 
(defn generate-event [n]
  (gstring/format "i 1 %s 1 %s" n (+ 20 (rand-int 1000))))
 
(string/join "\n" (map #(generate-event %) (range 0 10)))
 
 
</CsScore>
</CsoundSynthesizer>
 

• Everything within the CsScore tags is a Clojurescript evaluation block. The return value must be string with valid Csound Score.
• require andrequire-macros. js/require works for node modules. import will be added in next release.
• ns macro will NOT work from within CsScore tags, but can be present in files that are required.
• Classpath is by default only the root directory. Namespaces for external cljs file will therefore have to follow the relative folder-nesting structure from the root folder.
