Pseq([array that's changed on every repeat])

[Ali Rustamov]

Here is the code:

(
~seq = [4,2,7,2];

Pbind(
\dur, Pseq(
(~seq * Array.fill(~seq.size,{rrand(0.8,1.2)})).normalizeSum * ~seq.sum
,
inf
),
\degree, Pseq([0,1,2,4], inf)
).play
)


In this example
( ~seq * Array.fill(~seq.size,{rrand(0.8,1.2)}) ).normalizeSum * ~seq.sum
is calculates once and it's result is then repeated

How can I get it calculated every time before next repeat?

Hi,
The most general way to do this (i.e., you can adapt it to lots of other purposes) is to use a Prout,
build the pattern, and use embedInStream to have it run:

Prout({ | ev |
var seq = [1,2,3,4];
loop{
ev = Pseq( (seq * Array.fill(seq.size,{rrand(0.8,1.2)})).normalizeSum * seq.sum).embedInStream;
})

// holding onto the event with the ev variable is irrelevant in this example, but might
// be necessary is you embed a more elaborate pattern

Thanks a lot Ronald, I didn't know about embedInStream method and was
getting silence

Another typical construct is Pn plus Plazy.
The Plazy gets a Function to generate the pattern(s) to be used.
In your example the Function would be independant from the rest
of the Pbind, so it can be written outside.

~seq = [4,2,7,2];

// Pseq defaults to repeats = 1

f = { Pseq(({ rrand(0.8, 1.2) } ! (~seq.size) * ~seq).normalizeSum * ~seq.sum) }



// shorter durations, 5 cycles

Pbind(
\dur, Pn(Plazy(f), 5)/10,
\degree, Pseq([0,1,2,4], inf)
).trace.play
