Pif question

[Roc]

i have a Pif controlling a parameter of a synth based on duration, so
whenever \dur is above 0.3 it triggers the Pbrown:

Pif(Pbinop('>', Pkey(\dur), 0.3), Pbrown(0.25, 0.8, 0.05), 0.5);

but i'd like to make that more specific, so that whenever \dur is above say
0.5 it runs another pattern instead of the Pbrown above.

mmm?

not 100% sure but do you mean like this?
Pbind(\dur, Pseries(0.1, 0.1, 10), \amp, Pswitch1([Pbrown(0.25, 0.8, 0.05), Pseq([0.1, 0.2, 0.3], inf)], Pkey(\dur)>0.5).trace).play;
when dur is less than 0.5, then use Pbrown for amp. when dur is above 0.5 use the Pseq.
Pswitch1 is very a useful class.

not quite what i was after, cause i think that's equivalent to what i
already had.
what i want is (warning, pseudocode ahead):

if \dur > 0.3 -----> Pbrown(0.25, 0.8, 0.05)
if \dur < 0.3 -----> 0.5
*but then (this is the tricky bit):*
*if \dur > 0.5 -----> Pbrown(0.1, 0.3, 0.1)*

cheers, Fredrik

aha, i see. yes, Pswitch1 and Pif are similar.
but then Pswitch1 with a Pfunc maybe...

Pbind(
\dur, Pseries(0.1, 0.05, 20),
\amp, Pswitch1([
0.5,
Pbrown(0.25, 0.8, 0.05), //between 0.3 and 0.5
Pbrown(0.1, 0.3, 0.1) //over 0.5
], Pfunc({|ev|
case
{ev.dur<=0.3} {0}
{ev.dur>0.3 and:{ev.dur<=0.5}} {1}
{ev.dur>0.5} {2};
})).trace
).play;

or shorter...
Pbind(
\dur, Pseries(0.1, 0.05, 20),
\amp, Pswitch1([
0.5,
Pbrown(0.25, 0.8, 0.05), //between 0.3 and 0.5
Pbrown(0.1, 0.3, 0.1) //over 0.5
], Pfunc({|ev| (ev.dur>0.3 and:{ev.dur<=0.5}).binaryValue+((ev.dur>0.5).binaryValue*2)})).trace
).play;

there's probably a more elegant way though...

For a small number of cases, you can nest Pif.

That is, if you can write:

if(dur < 0.3) {
branch1
} {
if(dur < 0.5) {
branch 2
} {
branch 3
}
}

Then there is no reason why you can't write:

Pif(Pkey(\dur) < 0.3,
branch 1,
Pif(Pkey(\dur) < 0.5,
branch 2,
branch 3
)
)

It may not be super-convenient for large numbers of conditions, but it does work.
