midi to osc?
by Josh Lawrence 10 Jul '09

10 Jul '09

Hi everyone, I've been considering the idea of playing around with livenoisetools: http://www.pawfal.org/Software/livenoisetools/ ...just for fun. One of the problems I've come across is how to play "it". The software is written to receive nothing but osc messages. For example, the synthesizer, itchy, needs this to play a note (from the doc): /play iiiffffi [timeseconds timefrac ID frequency slidefreq volume pan message] Plays a note at the given time (in ntp format), on the given instrument with the given parameters. if the time is set to 0,0 it will ignore the time and play the note asap. The message parameter is interpreted as a char and if set to a "O" will cause an accent note to be triggered. this will be replaced by something more sane soon :) The slidefrequency gives a frequency to start sliding to (speed is defined by instrument modify commands for voices that support it). I'm wondering if it would be possible to use pd as a bridge between my midi keyboard and this software, i.e. I play a middle C and the correct messages would be translated to the software. Is this possible in pd? (Currently I have access to vanilla...) If so, can you point me to which objects I need to be looking for? If this isn't possible, do you have any suggestions as to a better method for doing this? I appreciate the help, Josh -- Josh Lawrence http://www.hardbop200.com

Pduino 0.5/Firmata 2.1 beta release
by Hans-Christoph Steiner 10 Jul '09

10 Jul '09

http://at.or.at/hans/pd/objects.html#pduino There are some nice updates to Firmata and Pduino. This release mostly adds extensions to the protocol to support more pin modes and their respective messages (Servo, I2C, Shift Registers, etc). Here are some specifics: - Servo support for StandardFirmata - support for using analog pins as digital I/Os for StandardFirmata - new message to set the poll rate of StandardFirmata - I2C Firmata example (needs Pd implementation) - switch back to 57600 for standard bitrate - made Firmata.begin(57600) explicit in all examples Please test and report and bugs or issues. We are trying to get this included in the upcoming Arduino 0017 release. Depending on the 0017 release schedule, we might be able to squeeze in Shift Register/Matrix support too. Also, just to note, this update includes code from (in alphabetical order): Ayah Bdeir Erik Sjodin Hans-Christoph Steiner Jeff Hoefs Shigeru Kobayashi Zach Lieberman (I hope I didn't forget anyone, let me know if I did). .hc ---------------------------------------------------------------------------- "It is convenient to imagine a power beyond us because that means we don't have to examine our own lives.", from "The Idols of Environmentalism", by Curtis White

Saving patch status
by Gabriel Vinazza 10 Jul '09

10 Jul '09

When you save a patch into a file the content of the number atoms for example are not saved, can somebody tell me if it is possible to save the entire status of the patch (kinda snapshot) or at least the numbers? I wan't to know if it is possible without arrays or similiar techniques, what is the easiest way?

looking for a frequency crossover (split a signal in 2 frequency bands)
by stefano.papetti＠univr.it 10 Jul '09

10 Jul '09

Hello, do you know about a ready made external/abstraction allowing to split a signal in 2 frequency bands with minimal crosstalk? I only found an old post mentioning x-equ~.pd but the link to the library doesn't work anymore. Thanks, S

Pd-extended bug
by Chris McCormick 10 Jul '09

10 Jul '09

Hi, At RjDj we're interfacing Pd with Python using a wrapper I wrote, and one of the developers had this bug report when he tried it with Pd-extended (not realising that there is another type of Pd). We're going to be using vanilla only, but I thought I should send a heads-up to the list anyway incase someone else runs into this Pd-extended weirdness. The bug report below doesn't happen on Pd-vanilla at all. See the attached files to try and replicate it. Basically it seems like Pd-extended is crashing, or not starting at all with Pd default command line args. Best, Chris. ----- Forwarded message from Martin Roth ----- From: Martin Roth To: Chris McCormick <chrism(a)rjdj.me>, Resent-Date: Thu, 09 Jul 2009 17:31:56 +0200 I have trouble being able to load pd from the command line with the -open flag, pointing at the relevant scene. That is, pd seems to load normally (though strangely showing only the console and not the editor gui). There is the following command line output: tk scaling is 0.999016715831 Pt_Start() called When I try to send the patch a message from python (to a netreceive object in pd), then python (using Chris' PdSend object) then I receive the following error: >>> pdSend.Send("hello") error: uncaptured python exception, closing channel <Pd.PdSend connected 127.0.0.1:30321 at 0x6f648> (<class 'socket.error'>:(32, 'Broken pipe') [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asynchat.py|initiate_send|219] [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asyncore.py|send|331] [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asyncore.py|send|331]) On the other hand, if I open PD and load the scene manually, then everything works fine. Thoughts? -Martin ----- End forwarded message ----- ------------------- http://mccormick.cx

playing a sample / mac
by Alexandre Bräutigam 09 Jul '09

09 Jul '09

Hi there! I'm using a simple sfplay patch to play a wav's sample. The open message box is: [ open pedra1.wav l ] because the pd file and this sound file are in the same directory. Using this patch in a XP computer, it works. When I try to do the same in a macbook, we hear no sound and everytime I bang the open message box, it says: "error: sfplay: can't open pedra1.wav" What's wrong? Does mac's pd needs some extra information on that open box? I'm using pd-extended 0.40.3 on both. Thanks !
