might have a *lot* of high frequency content.<br>
<br>
you could replace the counter in the above fexpr~ with a slower<br>
counter and it would have a coarser effect. That would reduce the<br>
pitch of the noise. If the counter got slow enough, it would sound<br>
more like abrubt panning between the signals instead of mixing the<br>
signals and adding noise.<br>
<br>
fexpr~ ($y1+$f4)-3*($y1+$f4>=3);<br>
$x1*($y1<1)+$x2*($y1>=1&&$y1<2)+$x3*($y1>=2)<br>
<br>
That adds a $f4 inlet, set to a float less than 1 to slow down the<br>
counter. It will pitch the noise down into a more usable range. At<br>
around 0.01-0.1, you'd start to hear some tones pop out (80-800 Hz).<br>
Probably at around 0.0001, it would start to sound like an arpeggio.<br>
<br>
Replace the counter with a random walk with drift on [0,3] might also<br>
be good. It would smear out the high frequency noise. It would give<br>
you 2 parameters to control the effect, speed and noise amplitude.<br>
<br>
Or you could try to add some cross-fading with another parameter that<br>
would cut down on the clicks. I don't know what you had in mind for<br>
this effect<br>
