Re: [sc-users] Gendy UGens guest star on iPhone

[Fredrik Olofsson <f@xxxxxxxxxxxxxxxxxxx>]

sorry for reopening such an old thread.  and not at all meant to  
belittle nick's fun gendy app.

but here are some tests.  on my ipod 2nd generation os 3.1.2 with  
recent isc build, i get these numbers...

{Pan2.ar({Gendy1.ar}.dup(20).sum,0,0.2)}.play
avg cpu: 62%
peak cpu: 64%
so that's 20 gendy1s but with more the ipod becomes unresponsive.

{Pan2.ar({Gendy2.ar}.dup(10).sum,0,0.2)}.play
avg cpu: 39%
peak cpu: 41%
and here 10 gendy2s.  more and the audio starts to crackle.


last here's a quite fun patch for the ipod/iphone.  takes between 25  
and 40%
{var x=AccelerometerX.kr(1,499,1).clip(1,499);var  
y=AccelerometerY.kr(500,999,1).clip(500,999);var  
z 
= 
AccelerometerZ 
.kr 
(0,20,0 
).clip 
(0,20 
);Splay.ar({Gendy1.ar(minfreq:x,maxfreq:y,durscale:z)}.dup(12).sum, 
1,0.25)}.play

i had to clip the output out Accelerometer ugen else the sound would  
blow up.  is it generating some inf values perhaps?
