[sc-users] Pattern question: How to set parameters of generators inside a local pattern scope during runtime and similar like the usage of the class Synth args and .set?

[Marinus Klaassen <marinus_klaassen@xxxxxxxxxxx>]

Hola list, 

I have a question about setting parameters of Patterns during realtime.
Normally I have a fixed set of patterns assigned to several slots of a
dictionary wich I can call up again to assign to more pattern processing or
to play and stop. I want to extend this by also to be able to change some
parameters in realtime when I play live with patterns. But still have the
advantage of calling up an unit with a set of default arguments and so, just
like: b = Synth(\stuff); a.set(\par, 2) to load an unit and to change the
parameters afterwards. 

Is this also possible with patterns in an easy way? 

// something like this: 
a = Pstuf({ arg freq = 100, amp = 0.1
                               Pbind(\freq,freq,\amp, amp)
}).play; 

a.set(\freq, 1000); 
a.set(\freq, Pexprand(100,1000)); 



// I tried it with Pdef but then I am bonded to also use name slots with
pdef wich preferably I want to avoid.

(
a = Pdef(\testa,
	Pbind(\freq, Pexprand(Pkey(\freqLo),Pkey(\freqHi)),\dur,0.1)).play
)

a.set(\freqLo, 100, \freqHi, 10000); 

// but then with durations it becomes a bit unhandy. since there are not
default values for it.  
(
a = Pdef(\testb,
	Pbind(
		\freq, Pexprand(Pkey(\freqLo),Pkey(\freqHi)), 
		\dur, Pexprand(Pkey(\durLo),Pkey(\durHi))));
a.play
)

a.set(\freqLo, 100, \freqHi, 10000, \durLo, 0.1, \durHi, 0.7); 


with kind regards,marinus
