Re: playing a NodeProxy with an envelope

James Harkins — 2013-05-25T07:06:13

Drifting a bit off of the original topic -- the request that often comes up
is to hot-swap pieces of a SynthDef in and out, without stopping the UGens
that don't need to change. JITLib is made for this, but I haven't seen that
it can spawn groups of interconnected proxies polyphonically, where each
group behaves like one note. As Lewis said: each event from Pbind would
trigger a single modular group.

Instr can build modular units, but I haven't seen that it supports
hot-swapping: e.g., Pspawner triggering some Pmono patterns where the
\monoSet events can replace the type of LFO instead of only the parameters.
With Instr, you could have a different LFO type on the next note, but not
change it during an existing note. The thing I wish I had time to write
would support the latter.

I'm fairly sure there isn't an extension library that handles both
requirements cleanly. If there were, the question would not arise so often
:-)

Re: PID of process run using Pipe

James Harkins — 2013-05-25T06:36:46

controlling a movie player that's playing a movie :) In that case the
process is being used all the time and I could use its pid to eg. see if
it's still running. Sometime it crashes end exits by itself and then when I
try to write to a pipe - sclang obviously hangs.

I have no strong objection to a pid getter, just wanted to be sure it
wouldn't be one of those things that's less useful than it seems at first
(because of the synchronous behavior of pipes, at least "r"eading pipes).

If the behavior is different for "w"riting pipes -- if sclang doesn't block
on a write request -- then sure, I can see how it would be useful.

To avoid the problem you mentioned, where the child process stopped and the
next write into the pipe causes sclang to hang, probably Pipe should detect
internally if the process died and close the pipe. It could also run a user
callback function, passing the exit code as an argument. That would take
some work on the primitive side, which I don't know much about.

Ah yes, so that means something like alt-[ will not be possible on the german keyboard, because [ itself already requires alt there, right?

Anyways, if you want me to try something out, schick's rüber.

Re: PID of process run using Pipe

Marcin Pączkowski — 2013-05-24T22:48:36

Thank you for answers.

The problem is that I can't use .unixCmd because using the pipe I'm
controlling a movie player that's playing a movie :) In that case the
process is being used all the time and I could use its pid to eg. see if
it's still running. Sometime it crashes end exits by itself and then when I
try to write to a pipe - sclang obviously hangs.

For closing things, I'd kill it first just to be sure

"kill %".format(p.pid).unixCmd;
p.close;

and that way I guess the process won't hang afterwards.

So would it be possible to request adding pid as a getter?

Best,
Marcin

I'll of course have to test how things work - so far I've only been able 
to test the (default) German and US keyboard under Linux and OSX here on 
my macbook. As far as I could see results were consistent (e.g. swapping 
z and y worked - z in querty layout and z in quertz layout yielded the 
same keycode). But there may be more difficulties waiting...

well, it looks like keys and keys with modifiers are mixed. I'll try to 
sort that out (of course 0.asAscii doesn't make much sense but there are 
useful resp. the ones that I need as well in the list).

I've now added the dictionary in which I store the keycodes and

see modifiers under Linux and Windows seem to be the same but keycodes 
differ. I'll try to sort it it out.

Object.writeArchive and precision

Michael Dzjaparidze — 2013-05-24T15:54:03

I just found out that .writeArchive used on (an array of) float(s) only saves up to 6 decimal places... 

a = 0.000273125;
a.writeArchive("~/Desktop/test.txt".standardizePath);
b = Object.readArchive("~/Desktop/test.txt".standardizePath);

// truncated to 0.000273
b.postln;

Is there a reason for this? And is there a way to force more precision? I had a look at .asTextArchive as this is used by Object in response to calling .writeArchive, but I can't make much sense out of it that quickly.

Hi GNU/Linux user,

Not that I am a Windows user…

Not entirely sure what you wanted in the second part, and also not sure if you wanted the normal, alphabetic keys with other modifiers than shift too. But the printouts don't look particularly helpful for that case anyways. I've given all for the letter a at the end of the attached list. The main part is just base-key and then shift-ke.

If you need more let me know

hello Windows users

Stefan Nussbaumer — 2013-05-24T15:01:48

hi,

I'm currently working on a shortcut-editor for a class of mine. 
unfortunately I don't have a machine running ms-windows resp. sc on 
windows. So, I' wondering if any of the windows users here on the list 
could do me a favour and run the following code for the blue keys in the 
attached screenshot:

(
w = Window("keyDown action");
w.view.keyDownAction_({ |view, char, mod, unicode, keycode, key|
"\t\t\t% -> \t\t\t\t%,\n".postf(char.asCompileString, keycode);
});
w.front;
)

also, I'd need the keycodes resp. modifiers for the arrow-keys (up, 
down, left, right).

for the modifiers - shift, alt resp. alt+shift - it would one can 
execute the following code - possibly modifiers for arrow-keys are not 
the same as the ones for other keys (at least on mac this is the case).

(
w = Window("keyDown (arrow) modifiers");
w.view.keyDownAction_({ |view, char, mod, unicode, keycode, key|
"\t\t\t% -> \t\t\t\t%,\n".postf(char.asCompileString, mod);
});
w.front;
)

Thanks a million to anyone willing to help me!

What do you mean by "mainstream framework" ?

The exampIe given quite clearly shows

I haven't extensively tested this approach

Pfunc { ~i } doesn't contain "proxy" in its name,
but in fact it acts like a proxy pattern, just as PL(\i).

With just a minimal bookkeeping effort
(which could also be automatized by simple methods/functions) ...

~s = Instr(\saw, ...);
