Bjorklund Class

I can't seem to embed other patterns within Pbjorklund - is that not supported?

I'd like to do things like:

Pbjorklund(Pshuf([3,5,8,13], inf),16,inf)

But I get...

ERROR: Primitive '_BasicNew' failed.
Index not an Integer

Re: Bjorklund Class

Here is another example of something I'd like to do:

var high = Pbind(
\instrument, \sinepluck,
\scale, scale,
\div, Prand([16,12],inf)
\amp, Pbjorklund(9,Pkey(\div)),
\dur, 1/(Pkey(\div)),
\degree, Prand([0,1,2,3],inf)+3
);

I bet this has something to do with patterns being stateless... I probably need to determine the \amp values a bar a time and insert them into a stream somehow... Plazy?

Re: Bjorklund Class

hi Bjorn,
i must say i cheated a bit when writing the pattern version of the
Bjorklund class. the sourcecode is just ^Pseq(Bjorklund(k, n),
repeats, offset); and that won't work with patterns as arguments as
you've discovered. i'll try to rework and will let you know.
meanwhile, below are two slightly ugly ways around your issues.

first issue...
(
var arr= Pshuf([3,5,8,13], inf).asStream;
a= Pbind(
\dur, 0.25,
\degree, Pseq([0, 5], inf),
\amp, Pn(Plazy({Pbjorklund(arr.next.postln, 16)}))
).play
)

your second example makes less sense to me. are you sure you want to
switch bjorklund's n every event? better to let it finish the n= 12
or n= 16 it was doing and then select a new n at random me thinks.
like this...
(
var high = Pbind(
\div, Prand([0, 1],inf),
\amp, Plazy({Pswitch([Pbjorklund(9,16), Pbjorklund(9,12)],
Pkey(\div).trace(prefix: "ampindex "))}),
\dur, 1/Pswitch([Pn(16, 16), Pn(12, 12)], Pkey(\div)).trace,
\degree, Pseq([0,1,2,3],inf)+3
).play;
)

Re: Bjorklund Class

right, i've now updated the Pbjorklund class to also take patterns as
arguments.
please download again: http://www.fredrikolofsson.com/f0blog/?q=node/434

now your two examples can be written like this...

(
a= Pbind(
\dur, 0.25,
\degree, Pseq([0, 5], inf),
\amp, Pbjorklund(Pshuf([3,5,8,13], inf).trace, 16)
).play
)

(
var high = Pbind(
\div, Prand([Pn(16, 16), Pn(12, 12)],inf).trace,
\amp, Pbjorklund(9,Pkey(\div)),
\dur, 1/(Pkey(\div)),
\degree, Pseq([0,1,2,3],inf)+3
).play;
)

thanks for noticing,

Re: Bjorklund Class

I actually figured out the Penvir solution myself and am happy to see that's a sensible way to do it.

Thanks for updating the class, and for having written it in the first place!
