-- region Lesson 1: exploring the ‘every’ function, including tackling the meaning of ‘$’
-- every
-- 'every' is one of a family of Tidal functions, that takes another
-- function as one of its inputs.
-- Let's say we had a simple pattern like this:
d1 $ sound "bd sd ~ cp"
-- ... and we wanted to speed it up like this:
d1 $ fast 2 $ sound "bd sd ~ cp"
-- ... but only one cycle out of three.
-- Here's how we'd use 'every' to do that:
d1 $ every 3 (fast 2) $ sound "bd sd ~ cp"
-- You can read this as "every 3rd cycle, make 'sound "bd sd ~ cp"',
-- go faster by a factor of two."
-- We'll take this apart to work out why we sometimes use (), and
-- sometimes '$' later. First, lets look at more, practical examples
-- of using 'every'.
-- We can use every with any function that takes single pattern as
-- input (and returns a transformed version as output). For example,
-- we can use 'hurry' instead of fast:
d1 $ every 3 (hurry 2) $ sound "bd sd [~ bd] [cp bd*2]"
-- Or use 'rev':
d1 $ every 3 (rev) $ sound "bd sd [~ bd] [cp bd*2]"
-- Because 'rev' is a single word, we don't actually need to put it in
-- parenthesis:
d1 $ every 3 rev $ sound "bd sd [~ bd] [cp bd*2]"
-- Here's a trick with using effects as functions..
-- Lets look at this:
d1 $ sound "bd sd [~ bd] [cp bd*2]"
# squiz "5"
-- We can treat the '# speed 5' bit as a function. If you think about
-- it, it does something to a pattern, just like 'fast 2' does.
-- So.. does this work?
d1 $ every 3 (# squiz 5) $ sound "bd sd [~ bd] [cp bd*2]"
-- Yes it does!
-- You can also add more than one 'every' manipulation, giving them
-- different periods for their first input, to create longer form
-- variety:
d1 $ every 3 (# squiz 5) $ sound "bd sd [~ bd] [cp bd*2]"
d1 $ every 2 (hurry 2) $ every 3 (# squiz 5) $ sound "bd sd [~ bd] [cp bd*2]"
-- keep going..
d1 $ every 4 rev $ every 2 (hurry 2) $ every 3 (# squiz 5)
$ sound "bd sd [~ bd] [cp bd*2]"
-- In Tidal, the pattern that a function is manipulating is generally
-- its final input, which makes it easy to 'chain together' functions
-- like this.
-- Ok as promised, lets go back to our original, simple example:
d1 $ every 3 (fast 2) $ sound "bd sd ~ cp"
-- Lets go through the three 'inputs' (also sometimes called
-- 'parameters' or 'arguments') for every.
-- [a] 3 - how often a function is applied
-- [b] fast 2 - the function that is applied
-- [c] sound "bd sd ~ cp" - the pattern that it's applied to.
-- Looking again at this pattern, you can see that the inputs are
-- given in three different ways:
d1 $ every 3 (fast 2) $ sound "bd sd ~ cp"
-- '3' is just on its own. It's a single number so tidal has no
-- problem knowing it's a single input.
-- 'fast 2' is in parenthesis '(fast 2)'. Then the word 'fast' and
-- number '2' are grouped together into a function, _before_ being
-- passed to 'every' as its second input.
-- 'sound "bd sd ~ cp"' has $ in front. We *could* have done this
-- instead:
d1 $ every 3 (fast 2) (sound "bd sd ~ cp")
-- That works fine, but '$' does the same kind of job. It passes
-- what's on its left, to the function on its right, as a single
-- parameter. '$' has really low priority, which means everything on
-- its right is worked out first before being passed to the left.
d1 $ every 3 (fast 2) $ sound "bd sd ~ cp"
-- This saves you from having to match up ( and ) around a function's
-- final input. It doesn't work with anything other than the final
-- input, so unfortunately this _doesn't_ work
d1 $ every 3 $ fast 2 $ sound "bd sd ~ cp"
-- The above would work out 'fast 2 $ sound "bd sd ~ cp"' first, and
-- would then try to pass that to 'every' as its second parameter,
-- which doesn't make sense to tidal, so it returns an error.
-- Note that when Tidal makes an error, if there was already a
-- pattern running, it will keep that going. If you're live coding
-- in front of an audience, you probably don't want an error to
-- result in silence!

setcps 0.6
-- Hear it straight
d1 $ splice 8 "0 1 2 3 4 5 6 7" $ sound "break:4"
-- Now with a more messed-up pattern
d1 $ splice 8 "6 1 [2 3] ~ 4 1 6*2 7" $ sound "break:4"
-- Try changing the cps to hear it at different speeds
-- Try manipulating the pattern of slices
d1 $ splice 8 (fast "1 [0.5 0.75]" "6 1 [2 3] ~ 4 1 6*2 7")
$ sound "break:4"
-- Now try all the above with 'slice' instead of 'splice'.
-- Slice _doesn't_ do the pitching up/down thing to splice the
-- sound to the step.
-- Here I put six slices from a loop originally in 4/4, to create
-- a 3/4 waltz
d1 $ splice 8 ("0 1 2 3 4 5") $ sound "break:4" # gain 1.1
d2 $ sound "kick snare*2 clap:4" # speed 2
-- endregion
-- region Lesson 4: chop and striate
-- Let's take a nice break:
once $ sound "break:8"
-- We can use 'begin' and 'end' to only play part of the sound, in this
-- case the final quarter of it:
d1 $ sound "break:8*4" # begin 0.75 # end 1
-- We can also use 'unit "c"' to change the behaviour of 'speed' so it
-- changes the playback speed to match the cps
d1 $ sound "break:8" # speed 1 # unit "c" # begin 0.75 #
end 1
-- Lets play four of those to fill the cycle
d1 $ sound "break:8*4" # speed 1 # unit "c" # begin 0.75 # end 1
-- Then play with the cps to hear it change, fitting the cps perfectly
setcps 0.8
-- Normally, I wouldn't use 'unit', 'begin' and 'end' by hand. Instead
-- I'd use splice / slice from the previous lesson, or 'chop' to cut
-- a sound into bits, and set the length of the loop in cycles with
-- 'loopAt'
d1 $ loopAt 2 $ chop 4 $ sound "break:8"
-- The above sounds pretty continuous, but it is chopped into four parts.
-- We can hear that by reversing the chopped up parts:
d1 $ loopAt 2 $ rev $ chop 1 $ sound "break:8"
-- If we slow the pattern we can hear each part separately:
d1 $ slow 2 $ loopAt 2 $ chop 4 $ sound "break:8"
-- Here's a different sample:
d1 $ slow 2 $ loopAt 2 $ chop 4 $ sound "break:9"
-- Now what happens if we put both breaks in the sequence?
d1 $ slow 2 $ loopAt 2 $ chop 4 $ sound "break:8 break:9"
-- With 'chop', it will play all the parts of break:8, followed by
-- all the parts of 'break:9'.
-- If we swap 'chop' for its friend 'striate', then parts from the
-- two breaks are instead interlaced:
d1 $ slow 2 $ loopAt 2 $ striate 32 $ sound "break:8 break:9"
-- Play with that striate value for fun:
d1 $ slow 2 $ loopAt 2 $ striate 32 $ sound "break:8 break:9"
-- If you use the *same* loop multiple times with striate, it kind
-- of stretches it:
d1 $ slow 4 $ loopAt 1 $ striate 4 $ sound "break:1*4"
-- Here's what that normally sounds like:
once $ sound "break:1"
-- 'bev' is an even longer sample..
d1 $ loopAt 16 $ striate 32 $ sound "bev"
d1 $ slow 4 $ jux rev $ loopAt 16 $ striate 128 $ sound "bev*4"
