#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

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.

#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

#slidiing arpeggios by Robin Newman 7th December 2014
#This piece generates major and minor arpeggios in C major and Minor
#created with different random octave settings
#and incorporates them with a sliding note and a variable cutoff
#each with a rising volume,
#using three separate synth voices, which is repeated 10 times
#before finishing with a C major chord
#the whole has a reverb effect added
