Hi All,

I've put together a solina_chorus UDO that emulates the Solina String
Ensemble's chorus module.  The UDO and test file are available at:

https://github.com/kunstmusik/libsyi/blob/master/solina_chorus.udo
https://github.com/kunstmusik/libsyi/blob/master/tests/solina_chorus.csd

and an audio rendering of the test is avaialble at:

http://kunstmusik.com/solina_chorus.mp3

It's based on information from J. Haible's Triple Chorus:

http://jhaible.com/legacy/triple_chorus/triple_chorus.html

and the Reaktor Solina-V module by Hugo Portillo:

(sorry, accidentally hit send before finishing the email!)

and the Reaktor Solina-V module by Hugo Portillo:

http://www.native-instruments.com/en/reaktor-community/reaktor-user-library/entry/show/4525/

The UDO takes in an audio signal and a pair of LFO frequency and
amplitude values.  The output is a mono chorused signal.

The Reaktor module implements a pair of delay lines for L+R stereo
processing, but I went with a mono implementation as it seemed closer
to what would have been found on the String Ensemble and in the J.
Haible Triple Chorus.  It sounded good to my ears in its current shape
so I thought it worth releasing, but any suggestions for improvement
are welcome.

Thanks!
steven

Very nice! I'll use it.

Thanks,

Very nice! I'll use it.

Thanks,
Mike

Thanks all, hope you all find it useful!  One thing to note, it should
be easy to modify the UDO to output the results of the three delays in
case you want to pan those or what not.  I'll probably just stick to
the current implementation for my own uses, but though it was worth
mentioning.

All best!

Thanks Iain for the kind  words and of course for your work! I'm catching up with studying your CSDs and learning plenty.

Cheers!

Hey hey Steven,
I finally had a chance to give it a listen and tweak the example a bit. The chorus sounds very good! At first I was confused by the reverb, which smeared it a lot. Thanks for sharing these lovely UDOs. They sound beautiful, are very usable and sometimes an education. <3

Hi Ffanci,

Yes, that's a good point: I added the reverb to the example but it is
not a part of the chorus.  I'll look at updating that example during
my next csound programming session to demonstrate various parameter
settings and to have both dry examples and ones with reverb.

Thanks and enjoy!

Steven, thanks for writing and sharing this!  I'm already enjoying the
unique characteristic it adds.

I have a comment and two questions for you about this:

First, the comment; I ran into a problem adding this into a cabbage
effect.  I had to make the following change to get it to compile:
  ;a0   = tablei(aphs, gi_solina_parabola, 1, 0, 1)
  ;a120 = tablei(aphs, gi_solina_parabola, 1, 0.333, 1)
  ;a240 = tablei(aphs, gi_solina_parabola, 1, -0.333, 1)
  a0    tablei aphs, gi_solina_parabola, 1, 0, 1
  a120  tablei aphs, gi_solina_parabola, 1, 0.333, 1
  a240  tablei aphs, gi_solina_parabola, 1, -0.333, 1

It looks like in the original function style of your version for some
reason in cabbage is outputting krate when an arate is expected...
but I have no idea why.  It works fine function style in csound from
the console, and changing to opcode style works fine in cabbage.
Without that change I got the following errors form cabbage:
INIT ERROR in instr 1 (opcode sol_lfo_3): table: index type
inconsistent with output
#k0 tablei.k aphs gi_solina_parabola 1 0 1
INIT ERROR in instr 1 (opcode sol_lfo_3): table: index type
inconsistent with output
#k1 tablei.k aphs gi_solina_parabola 1 0.333 1
INIT ERROR in instr 1 (opcode sol_lfo_3): table: index type
inconsistent with output
#k3 tablei.k aphs gi_solina_parabola 1 #i2 1
INIT ERROR in instr 1 (opcode sol_lfo_3): table: index type
inconsistent with output
#k0 tablei.k aphs gi_solina_parabola 1 0 1
INIT ERROR in instr 1 (opcode sol_lfo_3): table: index type
inconsistent with output
#k1 tablei.k aphs gi_solina_parabola 1 0.333 1
INIT ERROR in instr 1 (opcode sol_lfo_3): table: index type
inconsistent with output
#k3 tablei.k aphs gi_solina_parabola 1 #i2 1


For the first question, I think I found a typo/bug.  I noticed where
the delay is being applied "at2" is being used twice, and "at3" isn't
used at all.  Adding in at3 for the last delay line seems to add even
more to the sound.  I'm assuming this was just a simple copy paste
mistake, and that at3 is actually supposed to be used?

Next question, I noticed in the solina_chorus UDO that the audio input
variable is named "aLeft".  This made me wonder, what do you think
would be the best way to make a stereo version of this effect?  My
first guess would be a half phase shift of the sol_lfo_3 phasor on
only one channel.  Did you plan on implementing a stereo version, or
is that meant to be an exercise left up to the user for the sake of
simplicity?

Sorry for the bonus question, thanks again for this great contribution!

Yeah, I realized typecasting to a-rate was an option just minutes
after I sent the email.

I found the difference between console and cabbage very odd too.  I
just about have the cabbage effect cleaned up enough to share, so I
might start a topic on the cabbage forums with an example
demonstrating this for you.  My guess is it's really a problem
upstream in csound, but it'd still be nice to figure out the details
of the problem.

Hi Kevin,

Thanks for pointing out the copy/paste issue!  I've corrected that now
in the github project.

I originally used aLeft as I worked on making the UDO more along the
lines of what was done in the Reaktor ensemble by Hugo Portillo. In
that project, at1, at2, and at3 are used to control two sets of two
delays, with the left channel using at1 and at2 for two delay lines,
and the right channel using at2 and at3 for two delay lines. Hope that
helps!

steven

I took a few liberties to allow both traditional chorus and some more
non-traditional uses... but here's my first (hopefully release-ready)
cabbage version of this.  Thanks again Steven!

The lfo frequency and amp controls are 0-1 ratios of whatever the
overall scale is set to.  Enabling stereo chorus phase shifts the
phasor used for timing by half on the right channel, giving some
stereo depth.
