libpd and BUG Labs
by Andrew Turley 26 Apr '11

26 Apr '11

I work for BUG Labs. In my spare time I've been playing around with some ideas for using libpd on our device. I put up a blog post about my work here: http://community.buglabs.net/aturley/posts/240-libpd-Embedding-Graphical-Pr… Nothing revolutionary, but I thought people might enjoy seeing Pure Data on yet another platform (in this case, running in OSGi on ARM). andy

Re: [PD] Toggle Status
by Saul 26 Apr '11

26 Apr '11

Hi All, I'm sure this has been asked many times, but nothing comes up in an archive search. I'm using a multiple toggles to activate each element of a sequence. Is it possible to interrogate the status of a toggle or in fact any gui object. Thanks for any help, /S

Thank you all for your prompt responses. I've managed it with select and float, a bit messy. many and gridflow look very interesting and the addition to toggle would be a good one. Cheers, /S

jf/data - Data Structure Abstractions
by JF 26 Apr '11

26 Apr '11

I've a work in progress which could do with some feedback if anybody would like to take a look. It is basically a set of helper abstractions a little bit like FB's list-abs but for data structures. I wanted to use data structures as arrays of information but not be limited to floats like regular tables and also to have the ability to extend the functionality with graphical interfaces, nesting and other data structure advantages. They assume that one of the data field values in your defined template acts as an index for lookup and uses this index to perform operations with the other data field values of the scalar that index addresses. jf/data/append - Like append. jf/data/change - Changes values at a particular index. jf/data/clone - Clones a data subpatch window. jf/data/delete - Deletes a scalar at a particular index. jf/data/drip - Serializes objects in a data subpatch window like list-drip. jf/data/filter - Serializes objects in a data subpatch window that match a cross-connected boolean test like list-filter. jf/data/map - Maps a cross-connected operation onto objects in a data subpatch window like list-map. Download link and instructions on the jf abstractions page... http://chopstickkk.posterous.com/pages/jf-abstractions ...Please open the OVERVIEW.pd first which shows the abstractions in action using a step sequencer example. Any thoughts you guys might have would be greatly appreciated. Cheers, John.

potential fix for denormals in freeverb
by Ivica Ico Bukvic 23 Apr '11

23 Apr '11

All, Couldn't this be solved simply by adding -O2 compilation flag to the object, as per intel's document found at: http://software.intel.com/sites/products/documentation/hpc/compilerpro/en-u… Any thoughts? Ico

Re: [PD] Data Structures - Delete specific scalar?
by JF 23 Apr '11

23 Apr '11

Thanks João, I'm looking into a brute force workaround whereupon I drip the data structure and copy it to a buffer structure but with the scalars that I want to delete filtered out - then I clone this buffer back to the original thus deleting certain scalars. This should work for my needs. Also as an aside, I'm just reading Frank's data structure tutorial patches (I'm a beginner to this topic!). I really think that these should be added to the official vanilla documentation.

Re: [PD] (dynamically, temporarily) suppressing error message printing
by JF 22 Apr '11

22 Apr '11

As a follow up to this post which was the closest info I could find in the search... http://lists.puredata.info/pipermail/pd-list/2010-02/076198.html ...is there a way to suppress certain errors? I see in 0.43 I can change the log level but there seems to be no level that allows me to print messages but hide errors simultaneously. This would suit me and perhaps others very very well! Cheers, John.
