Re: [PD] Jack OSX latest beta and Pd jack midi
Very true, I have used this method fairly successfully although jitter is unavoidable. What this new beta brings to the table however is sample accurate midi as it creates a bridge between core midi and jack.

[PD] [PD-announce] electronic music ( with Pd ) event in London tomorrow and Tuesday night ?
Hi all, I will be in London tomorrow till Thursday, we will do an interactive dance performance, I will have Monday free and other days busy. Can anyone recommend/suggest me any electronic music ( with or without Pd) event happening in London tomorrow ( Monday 07.02) and Tuesday night ? Especially any Pd related event or any club event with good experimental music? I would appreciate any suggestions, please send them directly to my email :) thanks to all!!

YOu're probably much better off using the new Makefile template, it handles the OSX build issues. By default, it'll build universal for i386, x86_64, and PowerPC, and build targetting 10.4 so that you can easily use your objects on any Mac OS X machine that is running 10.4 or better.

Re: [PD] keyword/regexp search of documentation in a plugin
I'm making some more changes, like removing the checkboxes and using a combobox for the genres. Also using a combobox to enter search terms which has the benefit of a more user friendly drop-down menu for a search history (plus less code). Also, I changed the search function so you can type: foo bar and it will match if both foo and bar appear in the document (regardless of order). -Jonathan --- On Sun, 2/6/11, Hans-Christoph Steiner h...@at.or.at wrote: From: Hans-Christoph Steiner h...@at.or.at Subject: Re: [PD] keyword/regexp search of documentation in a plugin To: Jonathan Wilkes jancs...@yahoo.com Cc: pd-list PD-list@iem.at Date: Sunday, February 6, 2011, 11:29 PM Wow, that's really nice!

Ideally, this would use a search engine like xapian, then it could do keyword searches.
