[sc-users] very heavy click problem with this synth/routine

[sc <mailofdjeho@xxxxxxxxx>]

Hello, list

I found this synth from old time, (it's not mine, it's from this list, 
kindly offered by Batuhan Bozkurt) and having fun to play with it.

SynthDef(\junglism_mono, {|out = 0, pan = 0, bufnum, div = 16, slice = 
0, gateRatio = 1, stutter = 1, amp = 1, rate = 1|
    var needle, snd, addFrame, sliceDur, bufDur;
    bufDur = BufFrames.ir(bufnum);
    sliceDur = bufDur / div;
    addFrame = (slice * sliceDur);
    needle = Phasor.ar(0, BufRateScale.kr(bufnum) * rate, 0, bufDur);
    snd = BufRd.ar(1, bufnum, (needle % (sliceDur / stutter)) + addFrame);
    FreeSelf.kr(needle > (sliceDur / gateRatio));

    OffsetOut.ar(out, Pan2.ar(snd, pan) * amp);
}).add;

I wrote a nice GUI for it, running this routine with bunch of Pseqs.

~len =16;
~min = 0;
~max = 8;
~slice = Pseq(Array.fill(~len,{|i| rrand(~min, ~max)}), inf).asStream;
...etc.

Routine({loop({
            Synth(\junglism_mono, [\bufnum, ~buf.next, \div, ~div.next, 
\slice, ~slice.next, \gateRatio, ~gateRatio.next, \stutter, 
~stutter.next, \amp, ~amp.next, \rate, ~rate.next, \out,~ch[1]], 
~synthGroup);
~dur.wait;
    })}).play;

the only problem is that it's horribly clicky. especially when loading 
not percussive samples. but also with perc samples which has kinda long 
decay.
I tried to track down the source of the problem, but since it's not my 
synth and also that I'm quite bad at DSP stuff, I just can't figure 
out...randomly placing Lag or LPF here and there just mess things up, 
and create even more problems. I don't even know yet if it's my routine 
or the synth itself which produces click problems. I tried to set a 
master node with some filters, but I don't have knowledge on setting up 
filter parameters in a way to remove clicks without changing global ton 
of sound. the clicks are not this short, super high freq pop style, but 
more longer, and more...mmm...'rich' in spectrum...('sorry for my 
ignorance on DSP terms!!!)

I'm horribly lost...do anyone has any idea on how to remove the clicks here?

thanks...
