RE: bbcut2 effects set value

[Marinos Koutsomichalis]

I just repost it in case sb who can help hasn't noticed it...

.....................

Hello,

I have a gui that adds effects to a BBcut synth that runs.

f.e. 

var gr,bits;

gr=CutGroup(....);

gr.add(CutBit1.new(bits))

*where bits shall be avariable whose value depends over a slider

The last line adds a CutBit1 with first arg  set at bits. My problem is that it gets bits value when created and then it fails to adjust if I change that value.

If I had a synthdef I would just make a slider with .action_(|val| xxx.set(val.value))

How can I change CutBit1 first arg value after it is initiated??

if you study the many bbcut examples more carefully, you'll see how a  
function often is used as an argument.  the cutbit1 class is no  
exception.
so then instead of function {x} below, you can do {slider.value} (and  
probably you also need a {}.defer around it)

(
var sf, clock;
clock= ExternalClock(TempoClock(2.5));
clock.play;
Routine.run({
sf= BBCutBuffer("sounds/break",8);
s.sync; //this forces a wait for the Buffer to load
g=CutGroup(CutBuf1(sf));
a=BBCut2(g, BBCutProc11.new).play(clock);
});
)

x= 4; y= 8192; z= 1;
g.add(CutBit1({x}, {y}, srmult:{z}));
x= 2
x= 8
y= 4096
y= 1024
z= 0.05
y= 8192

Once you defer the function, its execution becomes asynchronous so the slider value will not be available to the CutBit.

Better to set the slider's action to set an external variable to the new slider value (and probably map the value onto a range other than 0..1 using a ControlSpec), and then refer to the variable instead.
