granular processor & generator

granular processor & generator

2008-02-17 by gasp_uleg

i am a fanatic of modular concept but i never had the money to build 
the gigantic modular of my dreams so i went into virtual and i 
specialized myself into Reaktor, where i've found everythink i ever 
needed. 

but the thing is that i deeply hate to use computer in concerts so 
now i'm trying to rebuild my reaktor setups into a totally physical 
way. with A100 and the other modulars everything i need can perfectly 
be done EXCEPT granulation which has become my favourite sound 
generator and modifier latelly.

i think not only granular cloud-delay processing is interesting. also 
a granular sample player would be an amazing module. 

i don't know much about DSP but if people like clavia have been able 
to fit all what is inside a micromodular or if pedal manufacturers 
are now using DSP for their new guitar pedals, it must be possible to 
find some cheap DSP technology to be fit into a vc modular format.

of course i understand development and technical expertise is very 
diferent for digital stuff than
for purelly analog electronics design but i'm sure ther are many 
young geniuses running out there with their nice diplomas in "very 
really complicated informatics" just willing to be emploid to program 
the complicated DSP algorithms for our modulars.

The expensive part is not the DSP, but the salaries of these young and 
willing developers. ;-)

Can several A-112s be used to construct a simple granular synth, with the
A-112s in wavetable mode? Each A-112 would represent a grain going into a
filter and then into a VCA, shaped by a ADSR? I guess a 4 grain synth would
cost a small fortune, but it's probably worth it.

Since the A-112s cannot toggle between record and play, my idea of the
granular synthesis can work only on prerecorded samples (assuming it was a
good/feasible idea to start with)

i realise this is slightly unhelpful half advice but i have a very
clear memory of reading - somewhere - instructions on how to install
gate control of record on an a112. it might even have been here. 

soldering gate control of knobs isnt as bad as you think, you're not
tinkering with the circuits, just the wires going to the knobs. if
you've not done it before just practise for a couple of hours on some
crud (and if you're like a professional repairman then my apologies...)

Granular synthesis uses anywhere from a few dozen grains to thousands of them.being able to change the number of grains is essential to get a good variety of sounds, I don't think a few fixed grains would do the trick

Hi Carlos,

As I said in my earlier mail that even a 4-grain system would cost a
fortune. On the other hand, a module that includes a DSP programmed to do
granular synthesis would also cost a lot, given that it will have to be a
powerful DSP to handle a high number of grains. It would also have to
include features like slew, filter, pitch shifting, amp, panning, etc, as
you would not be able to process grains separately with modules.

Weeeelllll.....

there is no reason a DSP-based granular module should not be able to  
output n grains to n outputs. Grains are computed as separate  
entities and get summed just before the output. So skipping the  
summing stage and replacing it with n outputs would not be such an  
issue. It would raise the price of a module because you'd use more D/ 
A's, though. So filter, amp and panning could all be done outside  
such a module, provided the module outputs trigger data etc for each  
grain.

What would really make the whole thing rely on a high-powered DSP (or  
more than one) is if you want to be able to modulate transposition/ 
position etc at audio rate....IMHO a must in a modular (can you spell  
"control rate vs audio rate" in reaktor? ugh)

I personally think that an 8 or 16 grain system would be sufficient,  
provided there was a way to link more than one in an "intelligent"  
manner.

Now what i think is the main issue with a module like this is: what  
control philosophy does it use? You can either have dedicated control  
of every grain or use some sort of "structural logic" that the module  
itself applies (aka "grain density" instead of separate grain  
triggers, "pitch jitter" instead of CV control of every grain pitch,  
"density evolution" instead of variable rate grain trigger signal). I  
personally think that in a modular system you'd want the discrete  
version, if i want meta-control only i can use reaktor or anything  
else.....the cool thing is to have the grain stuff *integrate*  
perfectly into the system, and for that you definitely need access to  
the individual grain's parameters. Now the downside of this is that  
it would  be a large and expensive module, and that doing some of the  
standard meta-attribute stuff would take a lot of patching. Maybe  
here there would be a good opportunity to create some structured data  
modules.....;-)


Now imagine what you could do with a grain thang at audio rate....use  
an audio rate pulse for the triggering of a grain, clock a sequencer  
with the same pulse and have that select playback position and grain  
transposition (or grain duration) of the grain thang, effectively  
getting a waveform that is F*N in length ( F being pulse frequency  
expressed in seconds, N being number of steps in the sequence). And  
we're just talking about grain #1 here :-)

hi Denis,
 
I love granular systems and you have described a very desirable module. I agree that you need as much control as possible and that would indeed make such a module expensive and large as I would prefer 16 grains but would settle on 8.
 
If only :o)

Re: granular processor & generato

2008-03-05 by gasp_uleg

yes denis, that would be a very nice aproach to it.
-every grain could be externally trigered by an lfo or oscilator.
-in case of a grain processor a separate triger for recording and
another for playback so pitch could be controlled by two ways.
-a cv input to control the playback direction of the grain
-a link connector could be included to add more grains if more
complexity is be needed.

Re: [Doepfer_a100] Re: granular processor & generato

2008-03-05 by Korhan Erel

So it boils down to what I say. Modular digital/analog granular synthesis is
expensive! :-)

A work around to this would be to get a multi-out sound card (say 8 outs),
send a grain to each output (easily done with PD, Max, LiSa, etc.) and
connect those outputs to modules... This way, only the source audio would be
digital (as it would be with a DSP module) and the processing would be
analog.

I do have such an audio interface but don't have enough modules to try it
out. Perhaps someone here who owns those monster cases full of modules
could?

Denis, are you Turkish by any chance? Your last name is Turkish, it seems.

Best,

Korhan
