Hi All,

Happy to share a generative music work "Autumn Meditation":

https://ide.csound.com/editor/1kR35B00GeRRmnGIFcwQ

It continues on with recent explorations of modal synthesis for its
plucked string instrument (file comments should explain the recursive
modal filter and parameters used). The instrument is performed using a
generative melody process together with feedback delay.

All best and happy autumn to you all,
Steven

Thanks all, glad you enjoyed it!

(Sidenote: It was kind of amazing to me that I could put that together
in the Web-IDE on my modestly powered Chromebook (Lenovo Duet) and
share it easily with everyone.  Just neat to have that ubiquitous
access to music making in the moments when you have an idea to try
something new. :)  )

Thanks Aaron! I've been using the newer style a number of years now
and find it quicker to write for live (and non-live!) coding and
easier for me when I switch between languages (i.e., JS, Java, C,
Python, Ruby, etc.). It might be just my own experiences and style
that shape my preference, but I can say at least for me I find it
pretty efficient. I particularly like using += and *= for summing and
multiplying signals as well as judicious uses of functional call
expressions for arguments.

Cheers!
Steven

no you can use array() and fillarray() in the same way.  i think in 
general csound avoids opcode names starting with a___, but steven 
prefers it because of readability.

Thanks! I thought I'd mention I was getting some crackles here and
there I found bumping ksmps up to 64 addressed it for me.  That's now
been updated:

Thanks Bernt!  I need to run this on desktop sometime to profile
Csound and see if there's performance bottlenecks. That said, I think
some of the glitches I thought were from init might actually just be
moments of clipping so I dropped the note amplitudes a couple of dB
and that seems to have helped. (Will keep looking at it when I have
some more free time! :) )

I did some profiling on my Mac and two things came up, one expected and one not.

The top-most cost actually came from using pan2.  It looks like it
will always calculate the coefficients for multiplication using
sin/cos (with the default itype of 0) which is a bit costly if a pan
value is constant.  Having a caching system for coefficients should
help with that in the constant pan value case but should add a small
cost for changing pan values.  I would suspect the benefit for the
constant case to be worth more than the cost in the changing pan case.
Anyone see any issues for implementing this?

The second-most cost came from copying asig variables which is due to
using UDOs which have copy-by-value.  Since the recursive mode filter
can instantiate up to 72 filters per instrument, the cost can be high.
The fix for that should go into CS7 to permit passing by reference.

Thanks John! Sorry I've gotten behind here on this thread. I'll try to
put together a test csd to measure performance before testing.

I had a chance to run the profiler and pan2 seems improved, thanks!
The performance now is dominated by copy-by-value with UDOs which was
expected.  Will plan to look at pass-by-reference in the intercession
between semesters.

I could make pan2 even more efficient with more code.  Might but it on the list.
