Subject: recording patterns aka pattern.record

so i need to record to disk some music ive done with patterns, which could
be modeled by the first example in "Pattern examples" (but usingt Ppars,
see below..)

i know sc3 has live recording, should I spend my time taking my code to
sc3? or is there a simple method in sc2?  

i _have_ been searching the mailing list archives (thank you bbedit!)
without finding a simple example.  am i searching the mailing list in
vain?  

the closest i could find was at the end of Streams-Patterns-Events 4..

stream = pattern.asEventStream(Event.new);

Synth.play({ ...

where in the example you can put Synth.record, add some paramaters, and it
records. but it fails with a Ppar. "Primitive '_Event_Delta' failed."

should i move on to sc3? i would do that already, but it appears my work
doesnt port as quickly as just wrapping it in {...}.send;.  

should i just record on another mac connected with an audio cable?<sad>
should i run away and join the circus?

still searching...thanks - j

Because that patch is setup to use a value pattern that returns Functions,
and a Ppar is an event pattern that returns Events.

asUGenFunc is what you are looking for.

(
var p;
p = Ppar([
    Pbind(\dur, 0.2, \midinote, Pseq([62, 65, 69, 72], inf)),
    Pbind(\dur, 0.4, \midinote, Pseq([50, 45], inf))
]);

Synth.record( p.asUGenFunc( nil, 2 ), 10, "mysoundfile.aiff" );

You're right, sorry about that..

Plazy : Pattern {
    var <>function;
    *new { arg function;
        ^super.new.function_(function);
    }
    asStream {
        ^function.value.asStream;
    }
}

Plazy is a Pattern that, when asStream is called, calls a function to create
the Pattern from which a stream is made.
Thus it is a way of creating and using patterns dynamically.

Just from my brief exposure the examples look pretty cool. Doesn't look

Isn't OpenAL primarily for doing specialized audio?  Is it suitable
for doing realtime composition/processing?

As far as software out there to that might nicely augment
SuperCollider, the old NeXT MusicKit looks like a possibility (thanks
for mentioning that, Jeff Shell).

Unfortunately, none of the DSP ugens run on Apple hardware, but it
could be fun to try to implement them.  I hope to take a look into
this sometime soon...

No I dont think openAL is for real time composition. My guess from briefly 
perrusing the examples and reading a little is that it will play around with 
spatialized audio, play soundiles, and bla bla. I was thinking of it as a way 
to use sound support on PC, although the SDK is cross platform, C++ programs 
without digging through directX docs, (which I've heard is a real pain). 
Looking back at my post I should have mentioned that that is what I was 
looking to do, not really for real time audio. SC is Where is the Next 
MusicKit located? Is it a C++ SDK?  (I must have missed that post)

Thanks for the quick response,

Andy

Subject: [OT] OpenAL 

OpenAL (http://www.openal.org) is an API that was developed to complement
OpenGL (Open Graphics Library) for the Audio world. Its main focus is to
provide a low-level API for virtual reality audio rendering. That means the
focus is audio for games. It is a powerful standard though and supported by
a large portion of the industry.
It is in no way comparable to SuperCollider in terms of functionality for
doing realtime electronic music though.

Are there people who use SuperCollider for room simulation and/or
HRTF-convolution?

Subject: [OT] HRTF

I found a set of "impulse responce" of HRTF, done by somebody at some 
university. that was lots of files, big files. (like, combination of
direction, azimth, and head type.) To do HRTF, you can do it either: 1.
impulse responce or 2. filter based on approximated graph (less data, I
guess.) Sound hack use #2 I guess (you choose direction and height, or draw
a graph) SC has Azimth panner no? can we hack it?

for the filter, you must use some sort of impulse responce, maybe by
direction, and simulate azimth... don't trust me.

First question:
Sequencing.
How can I record MIDI IN data in S.C.?
Pitch values are easy to print out by writing (note.midicps).post inside the
Voicer object.
It seems more tricky to store other data like durations values as Delta time
is 0.


Second question:
Real-time programming.
Does ayone know if it is possible to write some code in real time 
(while the main synth's code is already running)
for instance using a pause object with its own synth that would only be
activated
when the new code is ready?

You could send a function to a TSpawn via extra arguments (or modify the
TrigXFade class to take extra args).  You could then modify the function and
resend it to the TSpawn to dispose the old function and install the new one.

Subject: sc3 patching ugens

hi james and everybody.
i am recently getting into understanding SC3 but i could not figure out
the following:

how can i pass the output of an ugen to the input of another ugen that
has been started inside a
closed function sent to the RTVM at a different  time ?

i managed to use common variables for different closed functions (in the
RTVM) , they accept to point to
an ugen , but when i use setInput and the source is not in the same
function as the destination is, a 'notEnclosingGroup'
error occurs . I alspo tried using Plug and it's .source method , but
same result (of course).

a word about topSpawner , groups , transferring synths from one spawn to
the other (why?), would be of great help.
Thanks

You can't at this time.

Here are two links:

  http://ccrma-www.stanford.edu/CCRMA/Software/MusicKit/MusicKit.html
  http://musickit.sourceforge.net/

You can d/l it from the second.  They also explain what they are
trying to do with the MusicKit on OS X.

The MusicKit is written Objective-C and runs against OpenStep/Cocoa.
They say that there is a Python/Objective-C bridge that can be used to
access the MusicKit from Python.

Hmm ok cool. I was aware it wasn't really for composition, but I didn't know 
how standardized it was getting, although I knew creative labs supports it.

Part of what I'm doing right now opens up a nice way to record events of any sort.
(I have a previous event recorder, but the implementation is messy.)

This is part of the Player system I will be posting soon.
 briefly:
    Patch - can play an Instrument
    SFP - can play a sound file
    EventStreamPlayer - can play a pattern

for recording time-specified events of any sort, I will do a PriorityQueue based event
player.
normal patterns use a delta based system (each event determines when the next event will
happen).

so the time-specified event recorder could be written to by midi, wacom tablet or mouse
clicks.

the delta time zero problem you have is because you are checking the synth inside the
Voicer ?
check the synth immediately outside the voicer (if that makes sense)

schedSynth = thisSynth;

Voicer.ar({
        
    schedSynth.beats.postln;

    ...
})

errr... i worked with tucker-davis machines (DSP modules...) when i was
contracted by the DOD.  the physicist i worked with did most of the work,
since he knew what he was doing.  anyway... we worked with MatLab and did a
buttload of little projects involving HRTFs.  if anyone would like, i can
contact him and snag the MatLab code.  not that hard to go from MatLab (well,
there were some calls to another program he wrote in Pascal... i can try and
get that as well) to SuperCollider.


mainly research that involved normalization and some 'tricky' FIR/IIR
mathematics.  very cool stuff though.

Subject: text file i/o

I have a large array of literals, e.g.
z = [1,2.123, 44, "text", [2,3,1]];

that I want to simply read in from a file each time rather than 
include in the SC file.

I see how to read it in as a string, but I don't see how to read it
in as an array of literals, or convert it to such.  Is it necessary
to first write it as a binary file, and then read it in that way?

thanks

You can have a text file containing

#[1,2.123, 44, "text", [2,3,1]]

and then do this:

z = thisProcess.interpreter.executeFile("myFileName");
z.postln;

Hi,
This is a question about collections in S.C with a bit of Maths.
 
First, what I am trying to do: 

Since I have discovered Pswitch, I use it live to change patterns with a
GuiWindow.
It is very useful since it waits until the normal end of the current pattern
before 
starting the next pattern that I have selected manualy (so all my new
patterns start in perfect rhythm).


I have prepared a few duration patterns (in beats) tochoose from, in a live
situation: 
 Pseq([2,3,1,1],1)
 Pseq([3,3,2],1)
 Pseq([5,3],1) etc...

The queestion:

I would like to have the option of selecting  random patterns, 
with (7.rand+1) elements in the array and whose sum of elements
 always gives 8(which stands for 8 beats).

I want indeed to make sure I get this result of 8 beats because when I will
call a new pattern with Pswitch,this new pattern will for sure start 
on a strong beat (as the previous one had itself 8 beats).
I would like as well this random pattern to keep on generating patterns
(instead of repeating the same one) every time it as created 
a complete one (one whose sum of elements is 8).

I don't really know if I should look for a result in an array [] to then
place in a Pseq()
to obtain: Pseq([])....or if maybe I need to do that in a Pfunc({}) but
then, how can I get new 
results depending on the last ones?

Anyway, here are a few attempts to write the code:
Does anyone know how to debug it or even write it in a simpler way?
 
Cheers 
  Fabs

(
Synth.play({

var randomarray;
var counter;
var randompattern;

randomarray = {var n; n = (7.rand+1);

if (n = 1; {p = [8]; };);    //this part should be ok
if (n = 2; { a = 6.rand+1;
    b = 8-a; 
   p = [a,b].scramble; }; );

if (n = 3; { a = 5.rand+1;
    b = (6-a).rand+1;
    c = 8-(a+b); 
   p = [a,b,c].scramble; }; );

if (n = 4; { a = 4.rand+1;
    b = (5-a).rand+1;
    c = (6-(a+b)).rand+1; 
    d = 8-(a+b+c+d);
   p = [a,b,c,d].scramble; }; );

if (n = 5; { a = 3.rand+1;
    b = (4-a).rand+1;
    c = (5-(a+b)).rand+1; 
    d = (6-(a+b+c)).rand+1;
    e = 8-(a+b+c+d);
   p = [a,b,c,d,e].scramble; }; );
   
if (n = 6; {a = [3,2].choose; b = 4-a; p = [1,1,1,1,a,b].scramble;};);

if (n = 7; { p = [1,1,1,1,1,1,1,2].scramble;};);

if (n = 8; { p = [1,1,1,1,1,1,1,1];};);

   //maybe this needs to be outside the function?
counter=0;
randomarray.value; 
   //maybe I need to write randomarray.asStream and call randomarray.next?
};
     
randompattern = Pfunc({ var output;
     if(   (counter==p.size),{randomarray.value;
          counter=0;
          output=p.at(counter);
          counter=counter+1;
          output
          });

    });


Pbind(
\dur,a,
\ugenFunc, {  arg dur;  SinOsc.ar(200,0,
EnvGen.kr(Env.linen(0,dur,0,0.2),1)); };
 
 ).asSpawn(channels: 1);

})

(
var randomPatternFunc;

randomPatternFunc = { arg totalDur, numEvents;
    var attacks;
    attacks = Array.series(totalDur -
1,1,1).scramble.copyFromStart(numEvents - 2).add(0).sort;
    attacks.rotate(-1).put(numEvents - 1, totalDur) - attacks;
};

p = Pn(Plazy({ Pseq( randomPatternFunc.value(8, 7.rand + 1).postln, 1); }),
inf);


Ppar([
    Pbind(\tempo, 5, \dur, p, \note, Pwhite(0,12,inf)),
    Pbind(\tempo, 5, \dur, 8, \note, Pwhite(-16,-8,inf))
]).play;
)

Two main points.
The randomPattern function can be written much more simply.
Use Plazy to create patterns dynamically.

How randomPatternFunc works:
It takes two arguments, the total duration of the list and the number of
events in the list. It returns a list of durations.

The first step is to create a list of N random attack points in the measure.
First it creates a series from 1 to the totalDur - 1.
For 8 beat duration this would be [1, 2, 3, 4, 5, 6, 7].
It then scrambles the list and takes the first numEvents - 1 of them which
is indices (0 .. numEvents - 2). (If numEvents is 1 then the result of this
is the empty list []).
Then we add 0 to the list and sort what we have left.
This gives us the list of random attack points in the measure.

In order to generate durations from these we need to subtract each from its
right neighbor and subtract the last one from the total duration.
We do this by rotating the list left by one, replacing the last value with
the totalDuration and subtracting the original from this shifted list.

The result is a list of durations that sum to the total duration.
