Acorduri

Sonic Pi ofera suport pentru denumirile standard ale acordurilor. Incearca singur:

play chord(:E3, :minor)

Asa mai merge. Acum arata mai bine decat o lista bruta (si e mai usor de citit pentru altii). Ce alte acorduri mai suporta Sonic Pi? Ei bine, o multime. Incearca-le pe acestea:

• chord(:E3, :m7)
• chord(:E3, :minor)
• chord(:E3, :dim7)
• chord(:E3, :dom7)

Arpegii

Putem transforma usor acordurile in arpegii cu functia ‘play_pattern’:

play_pattern chord(:E3, :m7)

Ok, that’s not so fun - it played it really slowly. play_pattern will play each note in the list with a call to sleep 1 after each call to play. We can use another function play_pattern_timed to specify our own timings and speed things up:

play_pattern_timed chord(:E3, :m7), 0.25

Putem sa ii transmitem o lista de intervale de timp care va fi citita circular (dupa ultima valoare o reia de la inceput):

play_pattern_timed chord(:E3, :m13), [0.25, 0.5]

Aceasta linie este echivalenta cu:

play 52, sustain: 0.25
sleep 0.25
play 55, sustain: 0.5
sleep 0.5
play 59, sustain: 0.25
sleep 0.25
play 62, sustain: 0.5
sleep 0.5
play 66, sustain: 0.25
sleep 0.25
play 69, sustain: 0.5
sleep 0.5
play 73, sustain: 0.25
sleep 0.25

Cum preferi sa scrii?

Note that play_pattern and play_pattern_timed alter the sustain of the notes to fill the times. You can remove this behavior by setting the sustain: opt to 0:

play_pattern_timed chord(:E3, :m13), [0.25, 0.5], sustain: 0
