Re: [sc-users] pkey resolution

[James Harkins <jamshark70@xxxxxxxxx>]

There's a distinction between operators that get promoted into patterns, e.g.

Pkey(\x) + 1 turns into Pbinop('+', Pkey(x), 1)

... and other operations that have to be done as a function. Env.new().asArray instantiates an object, then converts it into an array, which is very different from the way a math operator applied to a pattern turns into a unary, binary or n-ary op pattern.

hi all,

i have some troubles accessing event keys via Pkey, when generating an

envelope:

p = Pbind(

\a, Pwhite(1, 10, inf),

\b, Pwhite(1, 10, inf),

\c, Env.new([0, 1, 0],

                    [Pkey(\a), Pkey(\b)]

                   ).asArray

\c2, Pfunc({|e| Env.new([0, 1, 0],

[e[\a], e[\b]]).asArray}, {})

).asStream;

in this case, Pkey isn't resolving the symbols for \c. in order to

resolve the symbols, i need to wrap it into a Pfunc pattern (like \c2).

i am curious, why is this the case?
