Re: [PD] PD on a laptop??
by nullpointer 25 Oct '01

25 Oct '01

Hi Jim, I use WinMe on a toshiba satellite 2800-400 PD runs fine except for the strange edit lock that seems to happen on windows machines.. (just close the patch and reopen it to allow editing again...) I use a midiman usb 2x2 midisport box for midi, although the timing isn't great (more windows than the usb I think) it's useable with a bit of tweaking... As for soundcards.. my advice is just to use your onboard card fo the time being cos it will pretty much gurantee compatibility with pd and wont hog any extra cpu time.. Externals.... theres the wami box, the digigram pocket and the almost mythical (here in UK anyway) hammerfall laptopcard... I've heard bad stuff about all of them so I'd suggest getting a trial run (return offer on the hardware e.t.c.) before you commit..There a new motu firewire unit thats sposed to be god,but i haven't got firewire so... anyway.. i hope this helps..I've done quite a few performances, just using the phones socket, and to be honest on an average PA in an average room you don't notice the quality level at all. oh and as far as video cards go .. most newish laptops come with savage video cards (OK) ATI cards (OK again) or NVIDIA geforce (brilliant), they all have decent opengl drivers i think although the nvidia card is kinda geared towards T&L systems like DX..

Implementing a "sustain" extern
by Larry Troxler 24 Oct '01

24 Oct '01

I recently dug up an old MIDI sustain extern that I wrote, which takes packed MIDI note/velocity pairs, and outputs the same, while treating them with sustain according to received MIDI sustain controller messages. I'm attaching this extern, in the hopes that someone can show that the way I implemented it was much verbose than need be. There must be an easier way! Along these lines, shouldn't such an extern be in the core PD distribution? After all, it would seem to be a very common need for anyone using MIDI input to drive audio processes.

Value vs receive names
by Peter Lunden 23 Oct '01

I find it stange that if a value box has the same name as a recieve then there will be an error message "error: value: no method for 'float'" when sending values to the receiver, is this a bug or a feature? --PLu bug.pd -------------------------- #N canvas 362 99 217 159 10; #X obj 26 29 r XX; #X floatatom 75 29 5 0 0; #X obj 75 59 s XX; #X obj 26 58 v XX; #X connect 0 0 3 0; #X connect 1 0 2 0; -------------------------

what is the right path to follow?
by Krzysztof Czaja 23 Oct '01

23 Oct '01

puk, puk... jest tam kto? How about score following in Pd? I suspect, that since the famous Dannenberg algorithm is patented, it is probably better to restrain from cooking any smart solution for a while. On the other hand the follow in max is so dumb and obvious, that it is hard to imagine how designing some variant of follow might cause any legal trouble. If this is `right path to follow', I will do the coding. Anyway, looking forward to any advice here. Krzysztof

Pop-up window
by andychen5018 23 Oct '01

23 Oct '01

Hi, everyone, Is it possible for PD object to generate a pop-up window to input arguments upon it's creation? I just think that having a long list of arguments when instantiating an object is cubersome and less clear. People might not even know that they can have arguments for the object. With pop-up window, it will be a reminder for people to put in arguments. And it will be also more clear to show what the arguments are for. If anyone has some ideas of how to do that, please help me. thx Andy Chen

Message boxes?
by Rory Walsh 22 Oct '01

22 Oct '01

Ok, I want ot change the text inside a message box by sending another piece of text to it. I can easily change the contents of a message box with 'set $1' for numbers but what do I have to do to change text? For instance with numbers -------- 1234 | this goes to a message box with set $1 -------- in it | | -------- set $1 | this outputs whatever number comes into -------- in to it | | -------- 1234 | And hey presto, -------- but how do i do this with text? Cheers ROry! ____________________________________________________________ Nokia Game is on again. Go to http://uk.yahoo.com/nokiagame/ and join the new all media adventure before November 3rd.

Midi notes.....analysis?
by Rory Walsh 22 Oct '01

22 Oct '01

Hi list, how about a little early morning teaser to get the heads going! How do I separate midi notes as I play them into pd? Say for example I want to analyse the notes of a chord? With route I can output all the notes of the chord to my pd window, so i figured if I use this with unpack that this will work, but unfortunately it only seems to work when messages containing one or more numbers are sent to it. I figure it doesn't like midi notes because they are sent sequentially. I can think of some rather time consuming ways to do this with counters and timers, but is there an easier way? Cheers! ROry. ____________________________________________________________ Nokia Game is on again. Go to http://uk.yahoo.com/nokiagame/ and join the new all media adventure before November 3rd.

error on closing patch
by Greg Rippin 22 Oct '01

22 Oct '01

Hello all, Using Win98, when I close certain patches, I get the message "error: .x97c600: no such object." The odd thing is that the object name it's giving changes every time--another example is .xa69f60. The patch operates and closes ok otherwise. Any idea what could be causing this? Thanks, Greg -- Greg Rippin, Graduate Assistant Music Technology Program New York University 35 West 4th Street, Suite 777 New York, NY 10012 phone 212-998-5422 fax 212-995-4043 musictechgrad.info(a)nyu.edu www.nyu.edu
