*From "Sean Wolfe" <swolfe AT spindlex.com>
I've been kinda reading and thinking about Additive Synthesis quite a bit
lately, but unfortunately I don't know that much about it.  Almost all the
Synth tutorials or teachings i find on the web deal with Subtractive
synthesis. (most synths use Subtractive synthesis). another thing, I'm
stating this and this could be an obvious question, but again, I only know
very little about Additive Synthesis, but it's possible to do on the Nord
right?

Has anyone tryed to do any patches to sound like some of the sounds out of a
Kawai k5000?
In the same sense has anyone tried doing Phase Distortion Synthesis like in
the Casio CZ series?

I'd like to try and jump out of the Subtractive Synth rut(but a very nice
and flexible rut that is).

And info would help. Thanks.

Sean

Hey Sean..

This has to be a quicky, otherwise I would attach some patches, but additive
synthesis is basically adding sinewaves ontop of each other till you get the
exact sound you want. Since a sine has only its fundamental frequency, you
build from the ground up. The sine bank is very nice for this, but you can't
place different envelopes per osc. The CZ styled synthesis is basically a
modification of the yamaha FM, and that can be reproduced in the FMB sine
wave module. Place an envelope (or several), between the carrier and
modulator(s) to get more interesting sounds. with slightly different
settings or time delay you can create some interesting noises.

When I get back later tonight I'll send you some simple constructs + a few
weird extentions of these ideas..

Sean,

FWIW, the awesome book "The computer music Tutorial" by Curtis Roads 
has an
excellent section on additive synthesis. I too, have been thinking a lot about
it lately. I have an old Kawai K-5m, but have never been brave enough to do
more than noodle on the surface with it. I just can seem to figure out a good
system to keep track of all of the control sources necessary to make all of
those frequency and amplitude changes over time. I too am looking for a source
that might give some tips about it. Does anyone know of such a source?

Cheers!

Sam E.

Sorry for my exuberance,
You must understand ...I used to have a Kawai K5 which allowed you to
controll 64 harmonics (sine wave oscillators) at once but only had four
amplitude envelopes to assign to them all. Im working on a patch that uses
eighteen harmonics each with it own envelope! Much more dynamic than
anything created by the lowley K5.  I *love* this little red box!

             Re: Additive Synthesis (...long) from hugo.haesaert AT skynet.be


*From Andreas Gaunitz <gaunitz AT konstfack.se>
Considerations about Additive synthesis:

I once had a Kawai K5. There are several inherent problems with 
Additive that manifest themselves in the K5, the greatest 2 being: a) 
It's impossible to know what harmonics to use to get the sound you 
want and b) you need to control a very large amount of data 
simultaneously.

a) In theory you can build any sound by adding harmonic sinewaves 
with different phase and volume to a 'base sine wave' whose frequency 
is 1/2 of the cycle frequency (that sine wave is called the 
fundamental). This is called Reversed Fast Fourier Transform. This 
might and might not be true. I've been reading up on inharmonic 
sounds lately (when studying cymbal synthesizing) and according to 
some sources you need to add inharmonic frequencies to get the noisy 
metallic sound of a crash cymbal. If so you could say that this kind 
of sound consists of a couple of harmonic sounds that are detuned 
relatively. Anyhow it's difficult to picture what harmonics need to 
be used to make a certain sound. This could be avoided by sampling a 
sound that is pretty much like the one you want and applying FFT to 
it to get its harmonic sinewaves. Then you could edit each sinewave. 
Unfortunately this will feel pretty much like applying EQ to the 
sound, instead of actually synthesizing. I once began writing an FFT 
applcation to port samples to the Kawai K5, but there were 2 problems 
that made me quit: 1) You can't decide the phase of the sinewaves on 
the K5 and 2) 64 harmonics is not much when you want sounds that are 
longer than 1 cycle  AT  20 Hz, for example a drum loop. So I quit. 
Another big problem with the K5 is that you can't detune individual 
sine waves, so you can't really do the inharmonic sounds - cymbals, 
that is ;-) ...

b) To make a sound that varies over time with Additive, you don't 
need envelopes. If your fundamental cycle time is 10 seconds, then 
you will get (at least) 5 seconds worth of time variant sound. 
However, most additive synths don't  use this paradigm because in 
most synths a sound is made up from 1 cycle in audible range, that 
repeats infinitely. If you made one of those 1 cycle = 5 seconds 
sounds it would sound like a loop that repeated after 5 secs. This 
would add a lot of problems like getting a non-clicking loop and 
such. So synth manufacturers concentrate on short waves but a time 
variant amplitude of the sine waves. In the K5 you have 4 volume 
envelopes. You can assign any number of the 64 sines to one of the 
envs. The problem is: How do I know which of the 64 sinewaves to 
fade, when I don't even know which sine produces which part of the 
resulting spectrum? The answer is: Filters = subtractive synthesis! A 
filter can be described as a device wich takes a range of sinewaves 
(selected by the filter charachteristics: HP, LP, Notch etc) and 
attenuates them at once... while editing the individual sine waves is 
exactly the same as using a very detailed EQ on the sound.


Different paradigms to explain the behavior of Additive synthesis:
1) Adding sinewaves with different volume and phase
2) Putting noise through a very detailed equalizer


Orthodox additive: Use only harmonic sine waves. Unorthodox additive: 
Detune any sine wave individually.


Additive implementations of different synths:

Kawai K5: Lots of sines, but a limited and slow interface. Might be 
better with 'puter editor. Sounds thin.

Casio VZ10m: Not an additive, but I tried to use 8 totally individual 
sines and add them together as a sound. Flexible but cumbersome. 
Sounds thin.

Yamaha FM synths: Putting the operators in paralell yields a flexible 
sine bank with control over pitches and volumes and possibly even 
some unorthodox feedback. You know how fun it is to edit FM on a 
small display though...

E-Mu Emax SE & Emax II: By far the most productive implementation for 
me. Altough it takes several minutes to compute a sound it produces 
an unexpectedly high number of high quality (lead) sounds. Emax uses 
a scheme called 'time slices'. You define at least 1 - the start - 
time slice and set volume and pitch for a number of sines. I don't 
think you can use more than 8 sines... (it's been a number of years 
since I had an Emax). You'll wait while the sampler computes 1 cycle. 
Then you play. If you define 2 or more time slices you set a time 
offset between them, and Emax computes the samples between the 
slices. I don't know why this works so well, but it might be that the 
default values are well chosen. I think the Emax mirrors the 
resulting wave to get a nice loop. In theory you would get a click 
when looping or mirroring a sound that has inharmonic sines in it, 
but somehow I haven't heard it very often on the Emax.

Nord mod: Allows only a few harmonics but offers excellent control 
capabilities. Don't need as many sines as you can detune each 
'harmonic'.
You could do an Emax with the NM: 8 sine oscs, 8 pitch ramps and 8 
volume ramps all ramps have the same time but different start and end 
levels. (think I'm gonna try tonight!). Don't use the sine bank 
though, 'cause you can't control the pitch of each sine.

forget the keyboards, what is that cat on your shoulders?  I have an Oriental
Short hair that looks similar....

for those of you who didn't back up on the site past the photo, take a look at
the digital images in the 2 galleries, some very impressive creations. I
particularly liked http://www.geocities.com/SoHo/Studios/7411/steve.html and
http://www.geocities.com/SoHo/Studios/7411/balcony57.html

and I have nothing to say about the modular in this reply. But given how off
topic this list became this week, I don't feel too guilty for my one post.

I got the enhanced Memory ME-1 for my K5000S this week, am installing it
today.  But an Oberheim Echoplex also arrived yesterday, so perhaps I'll hold
off on the memory and just get lost in loop land for the weekend.  I think
some of my Nord patches will work well with the echoplex.

Final note - add my thanks to Justin for offering to maintain this list even
though he just joined this community.  He is an active and respected member of
many other synth related groups and an excellent knowledge resource.

Hi All !

One should not forget the Synergy and it's rack successor (name 
escapes me) .  Used extensively by W. Carlos .  Only 32 partials per 
machine, but tunable .  Can use waveforms with somewhat more harmonic 
content than a simple sine, to make up for the small no of partials .

Then there's the Tekcnos Axcel Resynthesiser (sp?)

My K5m is capable of a good number of weird and wonderful timbres, 
but the most beautiful girl in town can only give as much as she's 
got ;-)

I reckon the ultimate additive synth has not been built yet .  DSP 
seems the way to go .

Bye for now .


Keep 'em oscillating :)

Threading: Additive Synthesis from swolfe AT spindlex.com
      • This Message

here are some designs. The additive patch is "Massidonia".. It is an
elaboration on the additive style of sound creation, with some added
elements (like a phaser) to make it enjoyable for me. Loops some notes, play
& tweak...
Not the average additive sounding patch.. (I'm about to go work on some
infinitely evolving pads).. Kees additive patch was not used as a template,
but this has a similar design (not sound though).

The Germania-tester patchs are more fun, IMHO.. they are basically templates
for FM creation, based on the guts of my Massidonia patch. Just connect the
mixer inputs to the various FMB inputs, play with the slave synchs,  mixer
volume and ENV settings to create some interesting sounds (after looping
some notes in a sequencer). I left one FMB input attached just to keep the
patch in the FM ballpark.

tester-example is just what it sounds like.. an example of a three op FM
synth using the Germaniatester patch (at least I think it was 3 op.. could
be wrong).

I didn't knob everything (wish I could), but the few knobs I did attach are
detailed in the notes of each patch.

Detail in the notes.. None of these synths are "basic" or 
"useful" or
any other type of adjective you could throw at them.. NOTE:

the wave-mayble patches are a stab at pseudo wavetable stuff..It dawned on
me that I was on the wrong track (a complex logic switch needs to be put in
place), so I just made these.. loop some notes (short and long) in a
sequencer and tweak.

Seq-wave and seq-wavesynch are remakes of the above with some self made
oscillators. can't remeber what the difference is between them now.. I have
a crap memory.

Wout's lulliby (ambient noodle remix of massidonia) goes straight to the
output, so cut volume before check it out
(knob 5 in this patch adds a nice alternate synth to the mix.. cut it in and
out ).

btw- all synth patches (& this includes other list member's patches as well
IMHO) sound like ass when solely played from the keyboard. I highly suggest
looping sequenced notes. then again, this is just a personal preference..

I'm trying to create a modular patch that sounds like a Vox Continental.
Seems like this might have already been done - anybody got some old combo
organ sounds, perhaps even the vox?

So here's my attempt. I got some information browsing the web as to the
structure of the instrument, and was also lucky enough to find a sample to
try to approximate. Sounds pretty good I think - certainly believable,
anyway.

Sorry for posting as a .zip, but whenever I post .pch's to the list,
people complain because my mail program doesn't attach .pch's in a
compatible way, apparently.

So have fun, do your remix of the Brady Bunch theme or some of the old
Doors tunes (my interest in the Vox Continental is due to the use of it by
the Doors. next I'll look at the Gibson 101 or.. something like that)

  Very true.  It's quite handy to have non-harmonic partials available, which
is something that I never liked about the K-5m.

  It's not all that bad once you start editing the envelopes of each harmonic.
You can get some fairly substantial timbral changes that don't "feel" 
like
EQ at all.  However it's still a hard thing to master.  I haven't spent
nearly enough time with this.

  Agreed.  It also helps a lot to have complex envelopes.  The Acxel has
128-point envelopes for both oscillator pitch and amplitude.

  True, though you need pretty successful low-frequency reproduction on your
output device to make this work.

  Operator pairs can also be thought of as "additive shorthand", 
allowing you
to create various harmonic spectra quickly.

             Pitch Shifting from knorthern AT previewport.com
             Was Additive Synthesis-> Fourier Series Implementation from dodo AT mindspring.com

Additive syntesis can be useful for "modal" synthesis. It is based on
resonant modes of instruments.
This basic exemple uses the first modes of a circular membrane.
These modes are not harmonic (but their frequencies are mathematically
defined) and their amplitudes depend on the position of the impact.
Here, the amplitudes are pseudo-random, a good model would include
a relationship between the modes and the axial distance of the impact...

Many musical scales are derived from modes...

There have been a number of good pitch shifter patches posted. I don't

They are not perfect, and have clicks and stuff, but they do shift your

Theres just not enough delay available in the nord (unless maybe by using 3
slots in an out->in->out->in->out configuration?)

I tried once too, envisioning several delay lines that cycled through
loading stages (where they are fed by the audio in) then pitched up or down
to match the shift.  I probably screwed up the logic anyway, but mostly I
think you need larger delay lines to make it work.  I got some interesting
distortions though... wonder if those patches are still in my NM?

Wish I had a nord at work so I could check.  We should add a 'How do I get
the accounting department to let me expense a Micro Modular for use at
work?' section to the FAQ in progress....

Hi Chris,

I made a pitch shifter about half a year ago. It can be found here:

Use knob 3 to shift the pitch up or down.

My differential equations book had a solution of the wave equation that gave
the frequencies and amplitudes for the partials of a drum head. Their
amplitudes were functions of the position of where the stick hit the head.
There were also constants describing the head and the stick used to hit it.

I used the solution in a NM patch, but it was nothing special. Better
inharmonic results could be had with FM synthesis.

This lead me to thinking... I'm not familiar with C Sound except a few
tutorials I read. Would it be possible to use it or maybe a Kyma to create a
set of partials based on a Fourier series? I figured it might lead to some
fairly realistic sounds.

It might even be possible to implement a simplified, albeit useful, version
on the modular. I'm not even sure where to begin, though.

Guess I should review those partial diff eq notes.
