hi list,
does anyone knows what is the difference(technical and
in terms of sound)between the AS comb filter module
and the classic warm sounding roland analogue chorus
found in keyboards like juno60,jx8p and rs09???
i'm interested to know because i like a lot the warm
roland chorus sound...

I do not know the difference but I made a short demo you can find in
"Files/sound" folder.

hi arnauld,
thanks for uploading the clip but i don't have winamp installed,so i 
can't listen to it...maybe if you can make it a mp3...?
but,please,don't get in trouble i'll buy one,anyway...:-)

Hi Bakis

I used to own a Juno 6 many years ago. The chorus on it was stereo and 
had 2 fixed settings. I too, thought it was very warm and nice. I have 
suggested a stereo patch (below) which should generate some very good 
chorus effects and a whole lot more using the A.S. comb filter 
modules. You can also make use of this in mono if you use only one 
comb filter and skip the inverter.

I hope this is a help:-)

The comb filter module is not actually a chorus unit but it can be 
made to produce chorus-like effects. To get a stereo chorus, you will 
need two comb filter modules, an LFO and an inverter (you can use the 
buffer module as an inverter).

Use the triangle wave of the LFO and input it to the buffer module. 
(set the freq control to a slow cycle).
Take one output from the buffer to the CV vari input (don't use too 
much level here) of one of the comb filters. Take the inverted output 
to the other comb filter.

Input your sound (signal) to a jack multiple and then to the input of 
both comb filters. Also feed the input signal from the multiple to  
one of the input chanels on your mixing desk and set the pan to 
centre.
The outputs of the comb filters should be fed to the desk and panned 
hard left and right. !!! check the input levels to the desk !!! (sorry 
but I'm safety mad).

The interaction between the comb filters and the original signal will
cause you to hear a wide stereo effect. You have to play around with 
the settings until you hear the desired effect (for chorus, keep the 
settings of both comb filters the same) - or find some new very cool 
ones! 

Playing with this patch is such good fun:-)

Dave.

hello bakis,

the rs120 comb filter is a "normal" bbd device.
(bbd = bucket brigade delay = analogue delayline)
the juno-chorus is more like the rs310 reverb/chorus module,
these use another type of bbd. this bbd generates six 
unrelated taps instead of one.
thats why the juno-chorus sounds so fat.

best wishes

thanks selfosc,
that's what i was expecting to find out!
so,now i know that i'll need the reverb/chorus module
in my next integrator order!
