THESE FILES WERE WRITTEN FOR SONIC PI VERSION 1
THEY WILL REQUIRE REVISION TO WORK ON VERSION 2
I HAVE OTHER FILES FOR VERSION 2 POSTED ON MY BLOG
SOME OF THESE FILES ARE POSTED THERE IN REVISED VERSIONS
http://rbnrpi.wordpress.com


Posted here will be music files for use with Sonic-Pi on the Raspberry Pi.
If you have the Sonic-Pi music program isntalled (it is on the latest distribution for Raspian) you can start it up from the Graphic Desktop (there is a link under Education on the Start Menu). You can then copy and past the contents of one of the play files into one of the 8 workspace windows and click play to play it.

#playing with code loops and c-minor scales. Robin Newman Nov 2014
#this piece controls 7 loops with a metronome loops generating cues
#which also selects a synth name from a given list and stores it in a global variable
#a loop (vset) controls the overall volume of the piece, fading it up and down
use_debug false
set_volume! 0 #set initial volume

The programs were created using a near release beta of Sonic-Pi 2.1
Because of the processing required these programs will not work effectively on a
Raspberry Pi, but require the more powerful resources available on the Mac version of
Sonic Pi, although they should also work on a more powerful Linux box under say Ubuntu.
and probably on the Windows version of Sonic Pi too, although I haven't tested this.

The first program createsamples uses 6 live_coding loops to generate a pattern of notes
related to a c minor scale, together with a background ambi_lunar_land sound. The timing
is controlled by cue and sync commands using the metronome thread metro.

#a Glass Armonica "voice" for Sonic Pi by Robin Newman November 2014
# revised to use rpitch 2018; corrected 2022 for missing tr function
#This simulates the Glass Armonica invented by Benjamin Franklin and for which Mozart
#composed the piece played here
#This version uses rpitch: parameter added to Sonic Pi after the original was written in 2014

#Percussion track generator by Robin Newman, 1st December 2014 for Sonic-Pi 2.1
#Inspired by an article http://www.soundonsound.com/sos/feb98/articles/rythm.html
#This program generates a percussion programme defined over two bars quantised to 32 pulses per bar
#up to 10 instruments can be incorporated
#any instrument can sound on any pulse
#one of three volumes can be chosen for each instrument for each pulse
#a variable p sets the pulse tempo for each programme
#a variable n sets the number of bars the track will play for in 2 bar increments
#In this example three drum programmes are defined num = 1 to num = 3. num=0 plays silence
#These can be chosen in a live_loop by changing the variable num

#bass sample voices for Sonic Pi version 2. With Frere Jaques and chords examples

#sample based voices for any bass_xxx_c samples over 4 octave range from :c2 to :c5 by Robin Newman December 2014

#tidied up tr, pl, plarray definitions and added plchord to play chords.
#all of them now accept symbolic or numeric note entry
