python-sonic 0.3.0

Programming Music with Sonic Pi or Supercollider

python-sonic - Programming Music with Python, Sonic Pi or Supercollider
=======================================================================

Python-Sonic is a simple Python interface for Sonic Pi, which is a real
great music software created by Sam Aaron (http://sonic-pi.net).

At the moment Python-Sonic works with Sonic Pi. It is planned, that it
will work with Supercollider, too.

If you like it, use it. If you have some suggestions, tell me
([e-mail]).

Installation
------------

- First you need Python 3 (https://www.python.org, ) - Python 3.5
should work, because it's the development environment
- Then Sonic Pi (https://sonic-pi.net) - That makes the sound
- Modul python-osc (https://pypi.python.org/pypi/python-osc) -
Connection between Python and Sonic Pi Server
- And this modul python-sonic - simply copy the source

Or try

$ pip install python-sonic

That should work.

Limitations
-----------

- You have to start *Sonic Pi* first before you can use it with
python-sonic
- Only the notes from C2 to C6

f = s + (1.0/number_of_pieces)
sample(LOOP_AMEN,beat_stretch=2,start=s,finish=f)
sleep(2.0/number_of_pieces)

An infinite loop and if

KeyboardInterrupt:


If you want to hear more than one sound at a time, use Threads.

.. code:: ipython3

import random
from psonic import *
from threading import Thread

def bass_sound():
c = chord(E3, MAJOR7)
while True:
use_synth(PROPHET)
play(random.choice(c), release=0.6)
sleep(0.5)

def snare_sound():
while True:
sample(ELEC_SNARE)
sleep(1)

bass_thread = Thread(target=bass_sound)
snare_thread = Thread(target=snare_sound)

bass_thread.start()
snare_thread.start()

while True:
pass

Every function *bass\_sound* and *snare\_sound* have its own thread.
Your can hear them running.

.. code:: ipython3

from psonic import *
from threading import Thread, Condition
from random import choice

def random_riff(condition):
use_synth(PROPHET)
sc = scale(E3, MINOR)
while True:
s = random.choice([0.125,0.25,0.5])
with condition:
condition.wait() #Wait for message
for i in range(8):
r = random.choice([0.125, 0.25, 1, 2])
n = random.choice(sc)
co = random.randint(30,100)
play(n, release = r, cutoff = co)
sleep(s)

def drums(condition):
while True:
with condition:
condition.notifyAll() #Message to threads
for i in range(16):
r = random.randrange(1,10)
sample(DRUM_BASS_HARD, rate=r)
sleep(0.125)

condition = Condition()
random_riff_thread = Thread(name='consumer1', target=random_riff, args=(condition,))
drums_thread = Thread(name='producer', target=drums, args=(condition,))

random_riff_thread.start()
drums_thread.start()

input("Press Enter to continue...")


.. parsed-literal::

Press Enter to continue...




.. parsed-literal::

''



To synchronize the thread, so that they play a note at the same time,
you can use *Condition*. One function sends a message with
*condition.notifyAll* the other waits until the message comes
*condition.wait*.

More simple with decorator \_\_@in\_thread\_\_

.. code:: ipython3

from psonic import *
from random import choice

tick = Message()

@in_thread
def random_riff():
use_synth(PROPHET)
sc = scale(E3, MINOR)
while True:
s = random.choice([0.125,0.25,0.5])
tick.sync()
for i in range(8):
r = random.choice([0.125, 0.25, 1, 2])
n = random.choice(sc)
co = random.randint(30,100)
play(n, release = r, cutoff = co)
sleep(s)

@in_thread
def drums():
while True:
tick.cue()
for i in range(16):
r = random.randrange(1,10)
sample(DRUM_BASS_HARD, rate=r)
sleep(0.125)

random_riff()
drums()

input("Press Enter to continue...")


.. parsed-literal::

Press Enter to continue...




.. parsed-literal::

''



.. code:: ipython3

from psonic import *

tick = Message()

@in_thread
def metronom():
while True:
tick.cue()
sleep(1)

@in_thread
def instrument():
while True:
tick.sync()
sample(DRUM_HEAVY_KICK)

metronom()
instrument()

while True:
pass

Play a list of notes

.. code:: ipython3

from psonic import *

play ([64, 67, 71], amp = 0.3)
sleep(1)
play ([E4, G4, B4])
sleep(1)

Play chords

.. code:: ipython3

play(chord(E4, MINOR))
sleep(1)
play(chord(E4, MAJOR))
sleep(1)
play(chord(E4, MINOR7))
sleep(1)
play(chord(E4, DOM7))
sleep(1)

Play arpeggios

.. code:: ipython3

play_pattern( chord(E4, 'm7'))
play_pattern_timed( chord(E4, 'm7'), 0.25)
play_pattern_timed(chord(E4, 'dim'), [0.25, 0.5])

Play scales

.. code:: ipython3

play_pattern_timed(scale(C3, MAJOR), 0.125, release = 0.1)
play_pattern_timed(scale(C3, MAJOR, num_octaves = 2), 0.125, release = 0.1)
play_pattern_timed(scale(C3, MAJOR_PENTATONIC, num_octaves = 2), 0.125, release = 0.1)

The function *scale* returns a list with all notes of a scale. So you
can use list methodes or functions. For example to play arpeggios
descending or shuffeld.

.. code:: ipython3

import random
from psonic import *

s = scale(C3, MAJOR)
s




.. parsed-literal::

[48, 50, 52, 53, 55, 57, 59, 60]



.. code:: ipython3

s.reverse()

.. code:: ipython3


play_pattern_timed(s, 0.125, release = 0.1)
random.shuffle(s)
play_pattern_timed(s, 0.125, release = 0.1)

Live Loop
~~~~~~~~~

One of the best in SONIC PI is the *Live Loop*. While a loop is playing
music you can change it and hear the change. Let's try it in Python,
too.

.. code:: ipython3

from psonic import *
from threading import Thread

def my_loop():
play(60)
sleep(1)

def looper():
while True:
my_loop()

looper_thread = Thread(name='looper', target=looper)

looper_thread.start()

input("Press Enter to continue...")


.. parsed-literal::

Press Enter to continue...Y




.. parsed-literal::

'Y'



Now change the function *my\_loop* und you can hear it.

.. code:: ipython3

def my_loop():
use_synth(TB303)
play (60, release= 0.3)
sleep (0.25)

.. code:: ipython3

def my_loop():
use_synth(TB303)
play (chord(E3, MINOR), release= 0.3)
sleep(0.5)

.. code:: ipython3

def my_loop():
use_synth(TB303)
sample(DRUM_BASS_HARD, rate = random.uniform(0.5, 2))
play(random.choice(chord(E3, MINOR)), release= 0.2, cutoff=random.randrange(60, 130))
sleep(0.25)

To stop the sound you have to end the kernel. In IPython with Kernel -->
Restart

Now with two live loops which are synch.

.. code:: ipython3

from psonic import *
from threading import Thread, Condition
from random import choice

def loop_foo():
play (E4, release = 0.5)
sleep (0.5)


def loop_bar():
sample (DRUM_SNARE_SOFT)
sleep (1)


def live_loop_1(condition):
while True:
with condition:
condition.notifyAll() #Message to threads
loop_foo()

def live_loop_2(condition):
while True:
with condition:
condition.wait() #Wait for message
loop_bar()

condition = Condition()
live_thread_1 = Thread(name='producer', target=live_loop_1, args=(condition,))
live_thread_2 = Thread(name='consumer1', target=live_loop_2, args=(condition,))

live_thread_1.start()
live_thread_2.start()

input("Press Enter to continue...")


.. parsed-literal::

Press Enter to continue...y




.. parsed-literal::

'y'



.. code:: ipython3

def loop_foo():
play (A4, release = 0.5)
sleep (0.5)

.. code:: ipython3

def loop_bar():
sample (DRUM_HEAVY_KICK)
sleep (0.125)

If would be nice if we can stop the loop with a simple command. With
stop event it works.

.. code:: ipython3

from psonic import *
from threading import Thread, Condition, Event

def loop_foo():
play (E4, release = 0.5)
sleep (0.5)


def loop_bar():
sample (DRUM_SNARE_SOFT)
sleep (1)


def live_loop_1(condition,stop_event):
while not stop_event.is_set():
with condition:
condition.notifyAll() #Message to threads
loop_foo()

def live_loop_2(condition,stop_event):
while not stop_event.is_set():
with condition:
condition.wait() #Wait for message
loop_bar()



condition = Condition()
stop_event = Event()
live_thread_1 = Thread(name='producer', target=live_loop_1, args=(condition,stop_event))
live_thread_2 = Thread(name='consumer1', target=live_loop_2, args=(condition,stop_event))


live_thread_1.start()
live_thread_2.start()

input("Press Enter to continue...")


.. parsed-literal::

Press Enter to continue...y




.. parsed-literal::

'y'



.. code:: ipython3

stop_event.set()

More complex live loops

.. code:: ipython3

sc = Ring(scale(E3, MINOR_PENTATONIC))

def loop_foo():
play (next(sc), release= 0.1)
sleep (0.125)

sc2 = Ring(scale(E3,MINOR_PENTATONIC,num_octaves=2))

def loop_bar():
use_synth(DSAW)
play (next(sc2), release= 0.25)
sleep (0.25)

Now a simple structure with four live loops

.. code:: ipython3

import random
from psonic import *
from threading import Thread, Condition, Event

def live_1():
pass

def live_2():
pass

def live_3():
pass

def live_4():
pass

def live_loop_1(condition,stop_event):
while not stop_event.is_set():
with condition:
condition.notifyAll() #Message to threads
live_1()

def live_loop_2(condition,stop_event):
while not stop_event.is_set():
with condition:
condition.wait() #Wait for message
live_2()

def live_loop_3(condition,stop_event):
while not stop_event.is_set():
with condition:
condition.wait() #Wait for message
live_3()

def live_loop_4(condition,stop_event):
while not stop_event.is_set():
with condition:
condition.wait() #Wait for message
live_4()

condition = Condition()
stop_event = Event()
live_thread_1 = Thread(name='producer', target=live_loop_1, args=(condition,stop_event))
live_thread_2 = Thread(name='consumer1', target=live_loop_2, args=(condition,stop_event))
live_thread_3 = Thread(name='consumer2', target=live_loop_3, args=(condition,stop_event))
live_thread_4 = Thread(name='consumer3', target=live_loop_3, args=(condition,stop_event))

live_thread_1.start()
live_thread_2.start()
live_thread_3.start()
live_thread_4.start()

input("Press Enter to continue...")


.. parsed-literal::

Press Enter to continue...y




.. parsed-literal::

'y'



After starting the loops you can change them

.. code:: ipython3

def live_1():
sample(BD_HAUS,amp=2)
sleep(0.5)
pass

.. code:: ipython3

def live_2():
#sample(AMBI_CHOIR, rate=0.4)
#sleep(1)
pass

.. code:: ipython3

def live_3():
use_synth(TB303)
play(E2, release=4,cutoff=120,cutoff_attack=1)
sleep(4)

.. code:: ipython3

def live_4():
notes = scale(E3, MINOR_PENTATONIC, num_octaves=2)
for i in range(8):
play(random.choice(notes),release=0.1,amp=1.5)
sleep(0.125)

And stop.

.. code:: ipython3

stop_event.set()

Creating Sound
~~~~~~~~~~~~~~

.. code:: ipython3

from psonic import *

synth(SINE, note=D4)
synth(SQUARE, note=D4)
synth(TRI, note=D4, amp=0.4)

.. code:: ipython3

detune = 0.7
synth(SQUARE, note = E4)
synth(SQUARE, note = E4+detune)

.. code:: ipython3

detune=0.1 # Amplitude shaping
synth(SQUARE, note = E2, release = 2)
synth(SQUARE, note = E2+detune, amp = 2, release = 2)
synth(GNOISE, release = 2, amp = 1, cutoff = 60)
synth(GNOISE, release = 0.5, amp = 1, cutoff = 100)
synth(NOISE, release = 0.2, amp = 1, cutoff = 90)

Next Step
~~~~~~~~~

Using FX *Not implemented yet*

.. code:: ipython3

from psonic import *

with Fx(SLICER):
synth(PROPHET,note=E2,release=8,cutoff=80)
synth(PROPHET,note=E2+4,release=8,cutoff=80)

.. code:: ipython3

with Fx(SLICER, phase=0.125, probability=0.6,prob_pos=1):
synth(TB303, note=E2, cutoff_attack=8, release=8)
synth(TB303, note=E3, cutoff_attack=4, release=8)
synth(TB303, note=E4, cutoff_attack=2, release=8)

OSC Communication (Sonic Pi Ver. 3.x or better)
-----------------------------------------------

In Sonic Pi version 3 or better you can work with messages.

.. code:: ipython3

from psonic import *

First you need a programm in the Sonic Pi server that receives messages.
You can write it in th GUI or send one with Python.

.. code:: ipython3

run("""live_loop :foo do
use_real_time
a, b, c = sync "/osc/trigger/prophet"
synth :prophet, note: a, cutoff: b, sustain: c
end """)

Now send a message to Sonic Pi.

.. code:: ipython3

send_message('/trigger/prophet', 70, 100, 8)

.. code:: ipython3

stop()

More Examples
-------------

.. code:: ipython3

from psonic import *

.. code:: ipython3

#Inspired by Steve Reich Clapping Music

clapping = [1, 1, 1, 0, 1, 1, 0, 1, 0, 1, 1, 0]

for i in range(13):
for j in range(4):
for k in range(12):
if clapping[k] ==1 : sample(DRUM_SNARE_SOFT,pan=-0.5)
if clapping[(i+k)%12] == 1: sample(DRUM_HEAVY_KICK,pan=0.5)
sleep (0.25)
