Like hand automation

Hello everyone, having a look at SC filter and missing a bit frequency hand automation you find in most DAWs I was wondering what would be the closest way to get a similar result.

Exprand gives a nice result but also produces some artefacts in the code I left below

– WARNING TO NOT PLAY AT FULL VOLUME —

I reduced the range of frequency to also reduce the artefacts but still please be careful with this code

~busCtrl =Bus.control(s);

//the synth for test
(SynthDef(\test,{|freq|Out.ar(0,BHiPass4.ar(Saw.ar(130),In.kr(freq)+30,0.5))}).add;)

//a lfo synth
	SynthDef(\lfoStep, {|out, dur, val| Out.kr(out,EnvGen.kr(Env.step([val,0],[dur,0]),doneAction: 2))}).add;

//the pbind to get the lfo to change normally every 1/4 beat but I did not add a tempo here so set as 1/8
Pbind(\instrument, \lfoStep, \dur,Pseq([1/8],inf),\val,Pfunc({100.exprand(1000)}),\out,	~busCtrl).play

Synth(\test,[\freq,~busCtrl])

would anyone have a suggestion about a way to get a similar result as the screenshot provided?

Many thanks ^^

this works.

({
BBandPass.ar(
		Saw.ar(130),LFDNoise1.kr(15).range(70,2600),0.5)
		
}.play)
