Sample slices pattern_timed

I’ve sliced a sample and am using the same slice at 3 different pitches.
I’d like to be able to store each of those pitched slices eg as a variable and then play them using something like play_pattern_timed.
How can I achieve this?

I’ve had a play with this this afternoon, and have got a solution. I’ve actually taken it quite a long way and had a lot of fun playing various pieces of music using sliced samples to get the note(s). Just needs a little more tidying up. I’ll post something tomorrow!
EDIT Better late than never…still just the next day, and here is the function that I came up with plus some examples below it.

#slicedSampleFunction.rb by Robin Newman, Feb 2023

#This function implements two things.
#first it uses a sample name, followed by parameters for a list of rpitch offsets,
#and a list durations, and thus is akin to the play_patterned-timed function for synths
#These three paramteres are required as listed below
#secondly it allows you to select a sample slice, and/or use start: and finish: paramters
#to adjust the characteristics of the sample source being used. In particular the :release
#parameter is useful if the slicing or start finish values give rise to clicks. YOu can reduce
#the value of release: until they disappear. Similarly atack can be used to reduce initial clicks.

#call splaytimed with args:
#sample name
#pitchlist: list of rpitch values
#durlist: list of durations for each sound
#offset: (added to pitchlist values)
#num_slices: (if not using default 16)
#slice: (slice to be played)
#start: and finish: (defaults are 0 and 1)
#sustain: (default is 0)
#release: (default will be current duration for durlist) can be reduced to eliminate clicks
#any other parameters such as pan:, amp:, cutoff: etc
#splaytimed is wrapped in a in_thread do...end which can be removed if you prefer
define :splaytimed do|sn,*args| #this plays patterns of notes with supplied associated durations
  av =args[0] #extract supplied args for pitchlist,durlist and offset
  pl=av[:pitchlist];offset = av[:offset];dur=av[:durlist]
  offset=0 if offset==nil #deal with missing offset
  if pl==nil or dur==nil
    raise "you must supply both pitchlist: and durlist: arguments"
  #puts "av",av
  #now delete pitchlist and durlist from remaining args
  #puts "av stripped",av
  #use a loop to play the sequence of relative pitches and durations
  pl.length.times do
    #put next rpitch and dur (and offset if there is one)  values into p1,p2
    #puts p1,p2
    #now create opts list for calling the sample by merging in rpitch sustain and release values
    opts=( { :rpitch=> p1,:sustain => 0,:release => p2 } ).merge(av)
    #note these values can be overriden in call to splaytimed eg add sustain: 0.1
    #puts opts
    #play thesample
    sample sn,opts if ![:r,:rest,nil].include? pl.look #don't play if a rest
    sleep dur.look #sleep current duration value

#example pitch list and duration list
#sample misc_crow starting at 0.2 (no slice)
splaytimed :misc_crow,pitchlist: p,durlist: d,start: 0.2
#sample misc_crow slice 0 of 2 slices  with pitch pffset -12
splaytimed :misc_crow,pitchlist: p,durlist: d ,offset: -12 ,num_slices: 2,slice: 0
#sample ambi-glass_rub slice 0 of 12 offset -24 starting at 0.8 through slice also added attack release and amp
splaytimed :ambi_glass_rub,pitchlist: p,durlist: d ,offset: -24 ,num_slices: 12,slice: 0,
  start: 0.8,attack: 0.01,release: 0.2,amp: 3
#sample ambi_glass_rub offset 12, slice 0 of 2 starting 0.4 through slice with attack and amp setting
splaytimed :ambi_glass_rub,pitchlist: p,durlist: d ,offset: 12 ,num_slices: 2,slice: 0,start: 0.4,attack: 0.01,amp: 2
#same as above but using sample ambi_glass_hum
splaytimed :ambi_glass_hum,pitchlist: p,durlist: d ,offset: 7 ,num_slices: 2,slice: 0,start: 0.4,attack: 0.01,amp: 2

#it works very well with external samples. If using a defined path to a folder and a numeric sample offset use sn = path,3
#and splaytimed sn,pitchlist:...... to enter the sample name

Also in a separate post I will publish some mixed up Bach that I have produced using the function above.
I hope the comments help you to follow what is going on. Please ask for further explanation if you want more.

Thank you, this is really very helpful, and I’ve been able to use external samples to gain the effect I was hoping for.

That’s great. I too have found it very versatile with a range of external samples.
