Try my Digital Waveguide Synthesis patches!
by Kim Taylor 04 Jun '07

04 Jun '07

Hello all, I've found this board very useful while doing my university project, I thought I'd show you what I've done with Pd. Any feedback at all would be really useful at this stage in the project. It'd also be nice to get some comments from you Pd guru's on how I've put it together. See attachment, or failing that http://www-users.york.ac.uk/~kt503/3yp/KimsWaveguides.zip My project is based on Digital Waveguide Synthesis (a type of physical modelling synthesis) which works principally on delay lines and feedback networks. My goal was to create a set of objects with which a user could build various types of plucked string models- essentially a basic modular framework. There are a few pre-made patch demos in the object set which you can load up and fiddle with instantly, which should sound plucked and string-like: check out 'demo1.pd', or 'demo2.pd'. Sliders and number boxes affect sound, and I hope it is obvious what they represent. I suggest try changing delay lengths, input/output positions, playing with different excitations (click excitation) or scattering impedances. For a quick guide to the theory have a glance at the readme. I haven't gone into great depth because I doubt there will be too many interested in it, but if you want to know more about how to use the objects, let me know and I'll try and explain it better. Cheers! Kim -- Kim Taylor www.puppydust.co.uk

Pd and Edirol UA-25
by Ede Cameron 04 Jun '07

04 Jun '07

After reading on the list about Edirol UA-25 I went out and got one on run on Debian. I can get sound when running in standard mode or midi in advanced but can't get both. I read on the list that some- one is running both midi and sound. Problem is the UA-25 seems to force 24bit in advanced mode which Pd won't run at or is there a way to get around this. Debian Etch Power Book 1.5 Edirol UA-25?

Re: [PD] what distinguishes a numeric symbol as an argument

I agree with Mathieu. Maybe one doesn't meet (or even need) those symbols *a lot*, but that would only imply that is not a *big* issue, not that it is not a *real* one. Also, it should be up to the programmer/user (I mean the PD user) to choose whether s/he needs or not to use them. If there are things that PD can load from a patch but cannot save, I think that is an issue that should be corrected. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=6588&d=1-6

Because it's cheaper to implement. If well done, it's also an intermediate step towards automatic threading. It's important to cut hard goals into easier goals, because it reduces required investment and gives quicker returns. Also, I wouldn't trust automatic threading to make use of the CPUs in the best possible way all of the time, *especially* for real-time. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada

Py/pyext
by David Powers 03 Jun '07

03 Jun '07

Hi list, I installed the latest pd-extended specifically hoping to finally use py/pyext. But py/pyext don't work I guess. Anyone know why? I'm on WinXP RC1. Specifically, I get two seperate issues: 1. pyext simply can't be created 2. py gives me the error "This application has failed to start because pthreadVC.dll was not found. Re-installing the application may fix this problem." Adding python scripting to PD is the single coolest thing I can think of to extend my PD abilities. Do I need to try to compile from the source? That's still a little scary for me, even though I code for a living it's all web stuff PHP/Ajax etc., so I'm not really used to it. I have cygwin installed, and MinGw, but I'm kinda clueless how to use them. I think I have M$ Visual C++ too... I did get something to compile once but it was a year ago and I forgot how I did it. ~David

Update - success
by David Powers 03 Jun '07

03 Jun '07

Hi list, My VJ patch now is working quite nicely, the only thing missing are the freeframe plugins. But hopefully there are some new Gem pix modifiers that can take replace this for me... So, if any of you have been holding off like me on upgrading pd-extending, I recommend you go for it. RC1 seems to be in quite good shape of winXp. ~David

loading wav.samples with readsf
by sebastian1981＠gmx.net 03 Jun '07

hi list, i`ve been trying to play wav.samples using the "readsf"-object but don`t have no luck "error: readsf: start requested with no prior 'open' ... you might be able to track this down from the Find menu." maybe its due to my message-box "open"!? + i couldn`t put the wav.files into the sound-folder of pd - using a mac with `PD-0.39-0` i can see the pd-folders only via "help > browser" - but can not paste something here... thank you very much sebastian -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.
