snd & inf-snd.el: multiple lines

Hi all,

Anyone working with the aforementioned combination? (snd as an emacs 
subprocess through if-snd.el). If I evaluate single lines all is well. 
If I highlight a region and try to get it evaluated in the snd listener 
through "Send Region" I get errors. Line breaks split the region in 
multiple subregions that of course don't make sense individually to the 
scheme interpreter.

Any way around this?
Thanks,

deconvolution in snd

Hi,

 before doing it myself in a probably less than optimal and
computationally inefficient way:

Has anybody implemented functions to perform deconvolution in some
straightforward way (with given two files) in snd, similar to
"convolve-files" and would be willing to share them, or does somebody
have some insights about how to use snd's internal machinery for
implementing it efficiently?

The files are fairly big (200-300 MB).

Don’t know if someone is interested, but the Grace-maxanneal -code is now on github

Was a good way of learning git commands :-)

[Algorithmic composition] Looking for examples for a book chapter

	[Apologies for a bit of cross posting]

Dear friends and colleagues,

For a forthcoming Handbook on Algorithmic Music I have been invited to write a chapter on knowledge-based
algorithmic composition. In this chapter I would like to focus on actual compositions that employ
techniques like grammars, constraint programming, techniques from machine learning like Markov
chains or artificial neural networks etc., and then discuss technical details in the light of such
examples. 

I am looking for material on relevant compositions. I am particularly looking for compositions that use
these or other relevant algorithmic composition techniques in a characteristic way. For example, there
exist compositions where filter movements are controlled with rhythmic constraints, where
multiphonics are composed with a constraint-based system, where rules control the resulting formats of
an overall orchestral sound to make the orchestra “speak”… So, on the one hand, pieces that use such
techniques in a somewhat unconventional way by going beyond the generation of mere note pitches and/or
durations are interesting for me. On the other hand, of course also the generation of note pitches and/or
durations can of course be characteristic, e.g., by further developing an underlying technique (e.g.,
by combining some knowledge-based technique with another technique), or simply the resulting music is
convincing. You get the idea.   

So, I would be grateful if you point out relevant compositions. If this is a composition of your own, I would
welcome informative details (e.g., score/recording, and a description of your algorithmic
composition technique(s)). 

I am looking forward to your responses. Thank you very much! 

Best wishes,
Torsten

Hi Anders,

I configured --with-gtk --with-pulseaudio; now the sound is working.
(actually, I dont need real-time).

Hello,

I installed snd from the tarball (on Debian 7.6 & Xfce):

This is Snd version 15.1 of 5-Nov-14:
    s7: 3.14 (18-Sep-14), Xen: 3.22
    ALSA 1.0.25
    Sndlib 24.1 (10-Aug-14)
    CLM 6.5 (31-Oct-14) 
    without any graphics system <===
    Compiled Dec  1 2014 11:39:21
    C: 4.7.2
    Linux 3.2.0-4-amd64 x86_64

How to add a graphics system?

Thanks,

rené

regds : s7 scheme -> embedding scheme


How do you embed a 'large' scheme program  with s7 .
Do you run any macros before you compile the c code to do the escapes for the scheme text? (see below)
I will appreciate if i can get access to those macros.


int main(int argc, char **argv)
{
  char *scheme_program = "(define (hello src)"
                            "(display src))"
                  "(hello \"joe\n\")";
  s7_scheme *s7;
  s7 = s7_init();
  s7_eval_c_string(s7, scheme_program);
}

Plot paths with gnuplot

Hi,

Learning to use dlocsig the possibility to plot paths in gnuplot seams like a useful feature. However, I can't quite figure out how to go about it. From reading the documentation (dlocsig) I understand that I use a list of functions, but I'm not sure how. I'm mainly using snd.

Best,
/Henrik

inf-snd.el

Hi!

I've successfully loaded snd from emacs but now I can't seem to get it to work. I'm using snd from planet ccrma (64) and emacs 24.3.1. Trying to run M-x run-snd-scheme yields:

Symbol's value as variable is void: $!

Same for run-snd-ruby.

Any help appreciated!
/Henrik

loading .so file in Grace

hi all,

How to load a dynamic .so file? I compiled S7 with HAVE_C_LOADER, but 
loading with load gives undefined symbol some hex-numbers and ELF, if I

Running just S7, load works giving  (load "xx.so" (envir....

I'm trying now on Linux, but should be the same on OSX.
