CM in Yosemite


I tried to compile CM with fomus and sdif in OS X 10.10.5 (after some changes in source code and updating the Juce library) got the following error:

ld: can't link with bundle (MH_BUNDLE) only dylibs (MH_DYLIB) file '/usr/local/lib/' for architecture x86_64
Is sndlib i386 only or a compiler flag needs to be set?

BTW, It did compile (after some work ) in Ubuntu 14.04 with Fomus, sdif and jack but it would be great to have a dmg for OS X with all the libraries included.

[snd] Is there a way to add dc offset to a file?

Snd newb here. I'm editing some impulse files for use in a convolver and
some of them have unwanted LF superimposed on them. As a result the
part of the impulse I'm interested in is further away from zero than
I'd like, making it difficult to trim the ends without a discontinuity.
I tried a HPF but it changes the shape of the impulse too much. Is there
a simple way to add a constant dc value to every sample?

Wonderful program BTW.

s7 on raspberry pi


I'm trying to compile only s7 on Pi, but if (Bill for sure) or someone 
else  knows, how to create mus-config.h with Pi, without premake or 
other stuff using just make and gcc, I'd glady would like to know.

Pi has audio out, also possibility to use usb-audio sticks & others. 
Chipkit Max32 (Arduino improved) works fine, so it's much easier for me 
to use arduino code to read and write i/o, as I haven't checked yet GPIO 
of Pi. I got Pi only few days ago, but ssh to Pi via WiFi works fine, my 
Pi usb <-> Chipkit works fine, too.

And also is there good (and cheap) ssh-client for Android? It would 
easier to use tablet for controlling Pi, than always MBP or Ubuntu laptop.

Python is out of question, I just know almost nothing of it.

Setting Y axis label position in Snd

Hi everyone!
Is there a way to change the Y axis label position in Snd?

I'm using, for instance, (set! (y-axis-label 0 0 transform-graph) 
"frequency") to create a label to make it clear that the sonogram is a 
graphing time in the x-axis and frequency in the y-axis, but the new 
label is created to close to the axis line! I want to move it slightly 
to the left. How can I do it?

SuperCollider Example Not Working

Hello All,  I'm new to Common Music and have been going through the examples and tutorials with fair success.  I'm stuck on getting the SuperCollider example to work, though. I *think* I'm stuck on this recommendation in the code: "Make sure SC booted port 57100 in the Post window." I've not been able to locate instructions for how to set the port.   I would appreciate any tips!

Thanks and can't wait to start coding some music!

Snd 15.8

Snd 15.8:

changed make-iterator with a closure argument -- the closure
  is now called without any arguments, and it should
  contain a variable named 'iterator? with a non-false value.

s7 now calls setlocale(LC_NUMERIC, "C") at startup.

What used to be called the run macro (clm optimizer) has been
  completely rewritten for about the sixth time; many changes
  in s7.h, etc. 

  1990: CL version (from Mus10 from MusicN)
  1993: CL + FFI
  1994: CL->C
  2002: Guile+Snd run macro
  2008: s7+sndlib
  2015: This time for sure!

  This change is about 1/3 complete, so view this version of
  Snd with grave suspicion.  

checked: gtk 3.17.4|5, sbcl 1.2.13

Thanks!: Anders Vinjar, Tito Latini, Greg Santucci, Mike Scholz

scheme, snd, cm_patterns.scm

Yes.  This is helpful, insightful.  I'm still trying to get used to scheme in snd.

how to set the working directory in grace?

Hi List

How can I set my working directory by code?

(set-working-directory! "/users/michael/Desktop") gives me an Error: 
set-working-directory! unbound variable

If I just open grace, there is no working directory by default, so I 
would like to make a load-file with, amongst others, this command.

scheme, snd, cm_patterns.scm

re: finding myself s7 challenged for CM_patterns.scm in Snd without Grace process, sprout etc.

I've kept digging with this and got something working, but it's not very pretty.  It uses 'list-ref'
in with-sound (), but that could be improved, I'm sure.

(load "snd/CM_patterns.scm")

(definstrument (examp1 start-time duration frequency amplitude sampling-rate)
  (let* ((beg (floor (* start-time sampling-rate)))
     (end (+ beg (floor (* duration sampling-rate))))
     (sine-wave (make-oscil :frequency frequency)))
     (do ((i beg (+ i 1)))
         ((= i end))
     (outa i (* amplitude (oscil sine-wave)))
     (outb i (* amplitude (oscil sine-wave)))

 (define xxx '(160.0  600.345  1000.0  400))
 (define aaa (make-heap xxx))
 (define bbb (next aaa #t))

(with-sound (:output "MyTest.wav" :srate 48000 :channels 2
             :header-type  mus-riff :statistics #t)
  (do (( i 0.0 (+ i 2.0)))
      ((>= i 2.0))
 (examp1   0        0.25    (list-ref bbb 0)    0.5 48000)
 (examp1   (+ i 1.0)    0.25    (list-ref bbb 2)    0.5 48000)
 (examp1   (+ i 2.0)    0.25    (list-ref bbb 3)    0.5 48000)
 (examp1   (+ i 3.0)    0.25    (list-ref bbb 1)    0.5 48000)

s7, cm_patterns

I'm finding myself  s7 challenged, trying to do an example using CM_patterns.scm in Snd using the listener. 

Seems that Snd doesn't have process, sprout etc. which Grace allows for working with patterns, so trying to figure out how to set up a control loop in with-sound in Snd using the patterns, but getting a bit confused.

I understand with-sound can use do for a control structure
(with-sound ( )
    (do ((k 0 (+ k 1)))
    ((= k 10))

But I'm confused about getting from the CM_patterns.scm prototype into a with-sound control loop.

 (define xxx '(100.0  22.345  3000.0  400))
 (define aaa (make-heap xxx))
 (next aaa #t)

I tried something like this just to test, but it prints everything, not just the heap pattern values.
(define (do-loop n)
 (do ((i 0 (+ i 1)))
  ((= i n))
 (next aaa #t)
  (display aaa))

(lambda (n) (do-loop n))
(list 10 20))

I'm wondering if anyone might have a simple working example to share?

snd15.7 on osx10.10

Dear Bill 

Thanks for the advice, fortunately on one machine the compilation went through !
on the other machine with the same OS version 10.10 I got a ld or linker error:
ld: library not found for -lXt
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [snd] Error 1

do you have any idea what I could check here?

all the best
