Applicators

apple - Probability-Based

Modify a generator with a certain probability

Example

(sx 'ba #t 
    (apple :p 10 (skip 2) :p 9 (rewind 2) ;; skip with probability of 10%, rewind with chance of 9%
        (cyc 'ba "bd ~ hats ~ sn ~ hats ~")))

---

every - Count-Based Generator Manipulators

Every so-and-so steps, do something with the generator or event stream.

Examples

(sx 'simple #t
    (cmp 
        (every :n 20 (skip 2) :n 33 (rewind 2)) ;; <- every 20 steps, skip 2, every 33, rewind 2
        (cyc 'beat "bd ~ hats ~ sn ~ hats ~")))

exh - Event Stream Manipulator

Exhibit event type, that is, mute all other events, with a certain probability.

Parameters

• probablility (int) - exhibit probablility
• filter (filter function) - event type filter

Syntax

(exh <probability> <filter>)

Example

(sx 'simple #t 
  (cmp 
      (exh 30 'hats)
      (exh 30 'bd)
      (nuc 'beat (bd) (sn) (hats)))) 

inh - Event Stream Manipulator

Inhibit event type, that is, mute event of that type, with a certain probability.

Parameters

• probablility (int) - inhibit probablility
• filter (filter function) - event type filter

Syntax

(inh <probability> <filter>)

Example

(sx 'simple #t
  (cmp (inh 30 'hats)
       (inh 30 'bd)
       (inh 30 'sn)
       (nuc 'beat (bd) (sn) (hats))))

pear - Probability-Based

Appl-ys and Pears (don't ask me why it's named like this, I like good pears and found it funny).

Example

(sx 'ba #t
    (cmp
        (pear (freq-mul 1.5)) ;; <- always multiply frequency by 1.5
        (pear :p 10 (freq-mul 0.5) :p 20 (freq-mul 2.0)) ;; <- with a probablility of 10%, multiply with 0.5, and 20% multiply by two
        (pear :p 20 (rev 0.2)) ;; <- with a probability of 20%, apply reverb
        (pear :for 'sqr :p 20 (freq-mul 1.7)) ;; <- only for sqr events, apply a multiplicator with a chance of 20%
        (cyc 'ta "saw:150 ~ sqr:100 ~ saw:150 ~ sqr:100")))
