petri-foo/specimen license formalizations/clarifications

by James Morris

hi, sorry for cross posting (again), but i want to try and get this out to all people who've been involved in specimen development over the years. i've add a gpl header to all source files with (where appropriate) copyright attributed to Pete Bessman as original specimen author and myself as current developer of petri-foo. there are some files i claim to be my own work, these are listed in PETRI-FOO_ORIGINAL_FILES along with short explanations. the changes can be found in the latest git commit. https://github.com/jwm-art-net/Petri-Foo if anyone has issues, or finds a lack of attribution to their work, or thinks how it's done is unfair, speak up.... but please don't get all esoteric about it ;-) regards, james.

wiki page: dead projects

by Renato

Hello, I created this wiki page http://wiki.linuxaudio.org/apps/all/dead_projects which stems from a thread I had started about a year ago here on LAD, asking for people to tell what software they found very valuable but no longer maintained. I have no prior experience with the wiki so I probably have made some mistakes, first of all for example I'm not sure if the page is placed in the right place. Would someone with more experience kindly point out or even better correct these mistakes? Also, maybe a distinction should be made: for example, while jack-rack AFAIK doesn't have a dev periodically maintaining it, I think no one would call it "dead", since it is quite usable and used; I'm pretty sure that if in the future it wouldn't compile anymore due for example to some gtk libraries not backwards compatible, someone would pretty fast come up with a patch. So, does it belong to the list? Or should we just change the name to "abandoned projects", and thus even examples like jack-rack would fit in? As of now there are two problems with the content of the page: 1) Tau physical modelling is a software that was mentioned in the said LAD thread, but I couldn't find it anywhere online. links anyone? 2) Softwerk by Paul Davis was mentioned, but then Paul chimed in and said he had just committed to svn, however I couldn't find the svn address... So, Paul, could you kindly provide us the svn address, to add maybe here http://apps.linuxaudio.org/apps/all/softwerk or if you're no longer working on it, could we add it to the list? Ideally this page would be a place where developers in search for a nice project would go, so I would find it good to link to it in some places, but I'm not sure where... probably here http://wiki.linuxaudio.org/apps/categories/development would be a good idea, but I wasn't able to edit the page. Then maybe even some place more upfront like here?: http://www.linuxaudio.org/resources cheers renato

Petri-Foo preview release: 0.0.2

by James Morris

Hello hello, The second official source code release Petri-Foo is now available. IMPORTANT: I have designated this release as a 'preview' release to indicate this is still a work in progress so that users may be aware things may change and their files may not be usable without alteration in future versions. HOWEVER: I feel Petri-Foo has moved along quite nicely since 0.0.1 in April and would like to share that work with a few more of you than are subscribed to the Petri-Foo developers list. WHAT'S NEW.... and good (since 0.0.1): * Default Patch A default patch using a looped generated triangle wave sample, with an ADSR, LFO, and MIDI CC setup with sensible/default values so a new user can immediately hear audio. * Selectable MIDI controllers MIDI controllers are now selectable amongst all the other modulation sources. This has two benefits, the first is being given the choice (of course), and the second is that you can now control how much effect the controller has. * Patchlist context menu You can now right-click on the patch list to get a context menu to allow you to perform add, remove, rename, and duplicate operations on patches. * Keyboard tracking Keyboard tracking has been added to all the parameters, and additionally, to the envelopes where it modifies envelope duration. * LFO Amplitude modulation The LFOs now have amplitude modulation so that. For example, the default patch uses this in combination with the MIDI Mod Wheel controller to control pitch modulation. * RAW sample format loading Allows one to load files never intended to be heard :-) * Removal of LASH support * Removal of ALSA *audio* output (note: ALSA MIDI still supported) * Miscellaneous bug fixes and GUI clean ups.

Determining Phase

by pshirkey＠boosthardware.com

Hi, Can anyone point me to a simple code example for how to determine the phase at a specific time in a waveform? ex. if I have a sample that is 5 seconds long and want to know the phase at 2.5 seconds I'm open to code in any language or a scripted example if such a tool exists. If there is an ui which has that feature I am also interested. Cheers -- Patrick Shirkey Boost Hardware Ltd

[OT] Comparison recordings of CoreSound Tetramic and Soundfield ST450

by Jörn Nettingsmeier

Hi *! For those interested in Ambisonic surround sound: finally I've managed to upload some side-by-side recordings of a Tetramic and the new ST450 which have been sitting on my harddisk for way too long. http://stackingdwarves.net/download/TetraMic_vs_ST450/ Hopefully the recordings are worth your time even if you're not currently shopping for a new surround microphone. Attached is a README that goes with the audio files. Enjoy, Jörn

I would not want to install system-wide though, so I tried to run from the local dir but got: renato@acerarch ~/src/yoshimi-midi-learn/prove/yoshimi/src $ ./yoshimi Default instrument tar file /usr/local/share/yoshimi/yoshimi-instruments.tar.gz not found Failed to establish program bank database Bad things happened, Yoshimi strategically retreats. Serious problems dealing with the instrument database Flushing log: Default instrument tar file /usr/local/share/yoshimi/yoshimi-instruments.tar.gz not found Failed to establish program bank database Bad things happened, Yoshimi strategically retreats. Serious problems dealing with the instrument database should I point it to the yoshimi-instruments.tar.gz that's found one directory up (in the root of the cloned git)? how? cheers renato
