summary:: Index into a table with a signal.
related:: Classes/Index, Classes/Shaper
categories:: UGens>Buffer
Description::
The input signal value is truncated to an integer value and used as an
index into the table. Out-of-range index values are wrapped cyclically to
the valid range.
classmethods::
method::ar, kr
argument::bufnum
Index of the buffer.
argument::in
The input signal.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
(
// indexing into a table
s = Server.local;
t = [ 200, 300, 400, 500, 600, 800 ];
b = Buffer(s,t.size,1);
// alloc and set the values
s.listSendMsg( b.allocMsg( b.setnMsg(0, t) ).postln );
SynthDef("help-Index",{ arg out=0,i_bufnum=0;
Out.ar(0,
SinOsc.ar(
WrapIndex.kr(
i_bufnum,
MouseX.kr(0, t.size * 3)
),
0,
0.5
)
)
}).play(s,[\i_bufnum,b.bufnum]);
)
