Hi,

maybe this could also be done with Pbindef ?
A thing to ensure would be proper naming of
Pbindefs generated (e.g. symbol + index)
and using these names with replacements


(
~makePbindefs = { |name, num|
	num.collect { |i|
		Pbindef((name ++ i).asSymbol,
			\dur, 0.2 * (i+1),
			\midinote, rrand(60, 90)
		)
	}
};

~setPbindefs = { |name, num|
	num.do { |i|
		Pbindef((name ++ i).asSymbol, \midinote, rrand(60, 90))
	}
}
)


~makePbindefs.(\a, 4).do(_.play)

// try several times

~setPbindefs.(\a, 4)

	
Set functions could be generalized to set an
arbitrary key to an arbitrary Pattern	and / or
differentiate for the index.

	
Greetings

Daniel
