I have pushed to GIT a first implementation of Nasca's "pad synth"
algorithm, as a C++ plugin function table. More will need to be done
to bring this up to the functionality of the CSD implementation, and
also documentation is still to be done. There is a padsynth_gen.csd
test file in the Opcodes directory.

Playing with the VST plugin ZynSubAddFX renews my appreciation for
what this code can do.

Please note, the Travis CI build breaks on this because the CI C++
compiler is not up to date. Could somebody with more familiarity with
the CI system see if this is a question of configuration (then please
reconfigure it to use C++11) or simply being behind (in which case I
will rewrite the code so Travis will compile it).

Regards,
Mike

Hi Michael,

Thanks for looking into this, I look forward to trying it out!
However, John has reported a failure to build on his system that is
the same as what is on CI.  I also just tried to build here on OSX and
got:

It also says fareygen.c in the padsynth_gen.cpp file. If I remove that
Include, I get essentially the same error as John.  Also, if I add
-std=c++0x or -std=c++11, I still get the same error.

I managed to get things to compile on OSX, using both -std=gnu++11 and

the build file change, but trying to run the example I get a crash

Hi Michael,

i did some experiments, and a few remarks and questions pop up. I hope you
can give me some answers:

- a remark about the example: ibw_cents = 56.96943 is redundant, because it
is p6_partial_bandwith in the ftgen

- in the example: ibasefreq = 440 ; can be lower or higher frequency; close
to played frequency is said to be best
Why? Is it 'in tune'?
And how does ibasefreq to fundamentalFrq in a sensible way, like A=440Hz?

- When comparing GENpadsynth with ZynAddSubFX:
    1. "gispec_len init 2^16" is samplesize in GENpadsynth, as i understand
it. This is Sample Size setting in ZynAddSubFX. The range there is 16k to
1M. My math is not great, but does that mean that the range possible in
GENpadsynth = 2^number of partials to 2^infinty - as long as it is a power
of 2 or 2+1?
    Of course, infinity takes a long time to compute, like forever, but this
means the range is larger than the 16k <-> 1M size in ZynAddSubFX? 
    
    2. the number of partials (hamp) are displayed in Csound when i run a
GENpadsynth.csd - but what does 
    maximum at 0: 0.369430
    maximum at 15: 0.383506
    maximum at 17: 0.396409
    .....
    stand for? How is this called in ZynAddSubFX?
    
    3. partialScale and harmonicStretchScale in GENpadsynth, are they the
Width and FreqMlt settings in ZynAddSubFX?

I did not express my gratitude to Michael for this opcode yet: thanks a lot!
Interesting sounds can be made easily and without too much CPU power.

Experimenting further and bringing the GENpadsynth back to its basics in
order to understand it, i made a csd that should result in a sinewave:
/gi_padsynth_1 ftgen 0, 0, gispec_len, "padsynth", 440, 1, 1, 1, 1 ;only 1
partial - sine?/

When i run the csd (attachment  sine_harmonics.csd
  ) i
do hear the sine but also a high pitched distortion (attachment 
padsynth_sine_close.jpg
 
). I do not get this distortion in ZynAddSubFX.
Can you explain this? Is my csd not correct?

Hi Menno,

I just saw this in my spam folder (I have no idea how to get Gmail to
not do this; happens with other emails to mailing lists from yahoo
accounts too).  I tried your CSD and am getting buzzing sound too.
I'm uncertain as to why this is.

The fault is with Yahoo not Gmail. Yahoo DNS entries explicitly tell
mail receivers to not accept mail from @yahoo.com addresses that are
not coming from a yahoo server. That means that mailing list messages
from a yahoo address will always be flagged as spam (actually we are
lucky the gmail servers are not draconian and outright discard the
messages). Very very annoying.

and googling "yahoo dmarc" have more info in case you are interested.

I was thinking, perhaps this bit of information could be sent in the

that is good to know, Felipe.
A lot of the messages that i sent to the Csound mailing list are never
answered - sometimes i think nobody has an answer, or nobody wants to
answer. I even have gotten to the point that i do mail a question or
something, but i do not expect a reaction back.

My mails however do show up in the Csound Nabble Forum, and that is exactly
my default Csound forum.

I will make a Gmail account and post from there in the future. (hoping that
somebody will actually react to my messages...sob...sob)

Sorry for the delay in my reply.  This thing is far from done, and the 3 sources of code that I looked at do things somewhat differently. I have a lot of other things that I need to do in the next 3 weeks, then I will go back and finish this up properly. I will add more types of bandwidth profile, write some documentation for the manual, and compare the output to other implementations to make sure I got it right.

Best,
Mike
