[PD] Question newbie mulit-dim array
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.

Re: [PD] soundfiler
Hallo, [EMAIL PROTECTED] hat gesagt: // [EMAIL PROTECTED] wrote: 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: 1. 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.

See the list fifo thread from last week or so for one such trick. If you want a list of lists data structure in Pd, you can do it with Pd's data structures however.

[PD] reverse delay for live signal processing?
Hello listy, A lot of my friends play instruments I would like to process in realtime. I understand that one popular approach is with delay objects. At first I was wondering if there was a special array that didn't give dropouts when it was rewritten in realtime. I don't think there is? But similar things could be accomplished if there was a way to access a [delaywrite~] buffer as dynamically as you can an array. One example would be reading the buffer backwards? I'm eventually looking to build something similar to one of those Boss Loopstations where you can overdub, reverse, etc in realtime. Granted, I know next to nothing about how these things are actually coded inside, but I thought I would pose the question and ask for ideas. Thank you!

Re: [PD] reverse delay for live signal processing?
Hi Kevin, i think you are getting dropouts when using arrays since the graphical data in the array object is being updated. Use the [table] object (which is the same as an array, but without the graphical display right visible. The waveform is accessible once you double-click it). Using arrays/tables you can also loop backwards, which is not possible using delread/write. So you would have to write into an array cyclically (phasor~ is your friend here), and read at the same position, feeding back the audio signal from the tabread to tabwrite, thus creating a loop. You would have to force pd to do this one after the other (order forcing) by putting the into a subpatch each, and connect those subpatches via audio patch cords. (there is also something on this topic in the help patches in you doc folder i think). Once you got this working, don't forget to check out the vasp library!

Re: [PD] reverse delay for live signal processing?
Peter! You're the man. That opens so many possibilities for me. Thanks! Always wondered what the difference was there. I will look into vasp.
