hello list,
I am just starting to use Pd and have a lot to learn. I am currently 
trying to build a simple sequencer for controlling 8 speaker channels. I 
use qlist for this where each line is formatted like this.
<millisec> <target> <message>
as example a line is:
1000 que [sp1 on] [sp2 off] [sp3 on]
I process this line and that all works fine.
Next thing I need to do is build some kind of system/interface that 
makes it possible for the user to actually record when a speaker is set 
on/off in time. To do this i want to create a timer that starts running 
when a speaker is turned on Pd needs to set a new line in the textfile 
that I use for the qlist. Problem is that each new line is added at the 
end of the file and evertime the user restarts the timer, all other data 
is lost.
So it seems that when recording, everything should be entered in an 
[list] this list needs to be sorted on the time entry.
Is this achivable in PD and do the real diehards out there think this is 
the way to go for me?
Does [list] have methods for sorting?
I hope all is clear.
Thanx and merry x-mas to all.
Jiri

Is it possible to create a [list] where each item is a [list]?
Thank you

Hallo,

Hi, like sent a message to soundfiler: [read -resize C:\Documents
and Settings\myname\folder\folder\filename.aif tablename]. I forgot
which way slashes go after C: and stuff. This is on PC, windows. K.
then there's a table object. I think that's what they're called,
like where there is a table in the subpatch of the object. I think i
called the table [table tablename 2040]. There's an error that I
believe "Documents and Settings" causes. Windows produces a "don't
change this foldername" alert if you try to change it to
"Documents_and_Settings". With a different soundfiler object and
messages to open up browsers to get the "filename.aif", the
"filename.aif" successfully loads to the "tablename" table. A
solution without opening browser window is preferable. Over and out
The most simple solution is to move the soundfiles to a directory
without spaces in its path name.
If this isn't possible, you need to get the space back into the list
message that is coming from the message box which stores your
space-polluted filename. Attached patch shows one possible way to
achieve this using the [list-l2s] abstraction from the [list]-abs
collection (also attached). The trick is to use [makefilename %c] to
generate symbols from their ASCII values. Sending a "32" into this
will let [makefilename] send a symbol-message whose data is the "
"-SPACE symbol.
[list-l2s] then concatenates every element in an incoming list using
this SPACE-symbol into a single symbol. So the three-element message:

      2.  3.

"C:/Documents and Settings/myname/folder/folder/filename.aif"
will become a one-element symbol:
    1.

"symbol C:/Documents\ and\ Settings/myname/folder/folder/filename.aif"
Here "\ " is meant to indicate the SPACE-symbol. You need to do this
*before* you build the final "read -resize ..." message of course, so
you use [read -resize $1 TABLENAME( afterwards.
As you see this is slightly complicated so again I'd suggest to just
move your files areound and avoid spaces in filenames generally like
the elders did.
