Re: [PD] Textual pd primer
This seems reasonable to me... I'm trying it out :) Miller I found the loadbang workaround doesn't always fix the no sound problem with -gui. This patch (which I posted to pd-dev in April) does: http://chrissie.fedorapeople.org/pd-nogui-startup.patch 2. (this is the really weird one) The expr object doesn't work if we launch Pd on startup ( init.d ) with nogui, BUT if we run it with -nogui in a command line over SSH it does. - we're running a custom build of Ubuntu, we had to do this to get the built in audio and outputs on the Gumstix to work. not sure how this is on the Pi. I'll get Tim to publish it soon anyway.

Re: [PD] Textual pd primer
I'm not sure, either. I've never really gotten around to running it. But it does seem to have an advantage on pd text files in that you can 'name' pd objects as ruby objects. So you can make it usable. not sure what FUDI, is, but it may well be a better solution.

Just a thought : wouldn't it be useful to create a pd-Raspberrypi@iem.ataddress ?

Nobody actually develops Pd in text mode, but gettin things running in an embedded way involves a good deal less graphics and can be intimidating or confusing at first.

Re: [PD] Textual pd primer
Hey Andy Pure data text files are not human readable, this is a simple fact of their existence, while you can tell what an object is and where it is on the canvas (although subpatches make even this difficult), the objects and inlets/outlets for wires are numeric, and you have to add anything new at the end of the file to avoid them pointing to the wrong place. I have come across this library for ruby https://github.com/nagachika/ruby-puredata/, which will remember objects by name and hopefully would be usable to make some pure data work in text. Although I've never gotten into it, so I don't know if it will be of any use. https://github.com/nagachika/ruby-puredata/ Andrew Date: Thu, 16 Aug 2012 20:58:07 +0100 From: padawa...@obiwannabe.co.uk To: sam.ra...@gmail.com CC: pd-list@iem.at Subject: Re: [PD] Textual pd primer I guess this is a case of working out best practices for development.

Re: [PD] Textual pd primer
Sam, we've been building and developing Pd on the gumstix embedded platform recently. I'm also running on a Mac so I can give you some of the knowledge I've learnt (it's been an uphill struggle for us too!) which may also apply to working on the Pi. - As Andy said you can use ssh to run pd remotely. You need to have installed Xcode on your mac, then use X11 and then log in as Andy describes. You can then run it just by typing pd, but don't forget your flags! we're currently using pd -alsa -nomidi -audiobuf 25 -r 22050 -blocksize 128 Tweaking all these will help! - The gui can be pretty slow this way so I generally build the patches on my mac locally, then copy them over to see how the processor on the Gumstix handles them. - couple of bugs we found when trying to run pd with -nogui 1. tables and delread objects behave badly unless you delay turning on the dsp. So in the patch that opens with no gui put a 1 or sec delay after a loadbang to turn on the dsp. 2. (this is the really weird one) The expr object doesn't work if we launch Pd on startup ( init.d ) with nogui, BUT if we run it with -nogui in a command line over SSH it does. - we're running a custom build of Ubuntu, we had to do this to get the built in audio and outputs on the Gumstix to work. not sure how this is on the Pi.
