Hi everyone, changing a bit of the subject in this list, is anyone here going to the ICMC? I'll be in Montreal for a week from 17/08, it'll be nice to meet some of you there. Regards Victor

dbus using up resources

by Patrick Shirkey

Hi, A recent observation has been made of the jack + pulse audio union that it uses up a lot of resources when running. It's not the first report that running pulse + jack causes things to overheat and lockup. The report was posted to the jack-devel list a couple of days ago. According to the original poster it is hald and dbus which are taking on the extra load. To me this sounds like an implementation bug in the jack or pulse code as neither hald or dbus should consume extra resources beyond their standard footprint. Does anyone have an idea of why this could be happening? It's probably a very simple oversight somewhere. I'm gonna spend some time now to test my system and see if I can reproduce it. Cheers. -- Patrick Shirkey Boost Hardware Ltd

Impro-Visor packages now on SF

by laseray＠gmail.com

Hi, After numerous back and forth emails with the Impro-Visor guy I realized there was no way to get through to him. This was even after a number of people on the Yahoo group for the program sided with him and I set them straight on the facts. Each one of them changed their position, but this guy would not despite any statement of facts, evidence, etc. So no point in trying to reason with unreasonable people. Thus, I have started a SourceForge project to host Impro-Visor stuff (yes, with the source code) and possibly a new line of development on a fork. Right now it is just important to make the binaries/code easily available for everyone (as guaranteed by the GPL). Only the last stable version is up at the moment (version 3.39). If anybody wants to join the project feel free, even people from the original project are welcome because this is about opening it up, not taking it over (which is sort of a slam I received from that guy when I let him know that the application binaries/source would be hosted on another project). I wanted to cooperate with people, but it was just too difficult for them to admit being wrong. So instead of just posting the source code for their latest preview, it was pulled. In spite of all their protests that they were completely in the right, the application was removed. Basically, an admittance that the GPL was being violated. Anyway, I still have that preview and the source code (via disassembler) and can possibly still put that up a little bit later. Raymond Improvisor: http://sourceforge.net/projects/improvisor

Email from Beat Kangz

by Michael Fisher

For what its worth... I received this from AJ at Beat Kangz. Could have just been an honest mistake really. I still have mixed emotions. --- *Hey Guys* * * *I have personaly contacted the creators of the LADSP plug ins we used and let them know our plans etc. In a rush to get the product out the door we forgot to include those credits. Which is now corrected on everyone that goes out the door. If you notice we didnt include the manual either lol. We are finishing that today and will be posting it as well as emailing it to all our customers so far. It will also include the list of credits. We regret not having it in the initial release and we have corrected that. in addition we will send them free copies etc.* * * *"That would be pretty awesome if they decided to open development"* This is exactly why we chose to go with LADSPA instead of VST. We want to shine a big spotlight on that dev community and also Donate funds to further help them create cool plug ins. We would even love to create a dedicated page on our site where they can sell or give away their creations and benefit from our marketing efforts. The more plugins the better for all of us! We are also now looking for talented programmers to write cool synths we can use too...... If you guys know who can do that, send them my way. We appreciate your biz Michael and hope you enjoy the product. Ronald I also appreciate your call today and hope we can find ways to work on projects together in the future. Give me some time to get this Thang off the ground and by 2010 i may be able get you those angels you are looking for. Peace and Respect AJA Prez of tha kangz

Impro-visor source code and fork

by laseray＠gmail.com

Hi all, If anybody is interested, I have decompiled the latest Impro-visor version, which has only been provide as a binary (in contradiction to the terms of the GPL). So if you want the source code just let me know and I will send it. I'm sure it won't compile immediately, since there are a number of incorrect constructs returned by the decompilation. I will work on this in the next while to have it compile. I think someone else mentioned they posted the older binary/source somewhere. Perhaps this can be hosted at the same location (have to look back to see where that is/who posted). Apart from that, I will be looking into forking Impro-visor in the next few days. After making contact with the responsible parties about the GPL violations, I have received no reply and the source code has not been posted along with the binaries as is legally required. I also contacted the department head at the institution responsible for this work to see if they would look into the matter. Perhaps they can sort this out in the next little while. Failing that, I will probably start a new project on SourceForge and be looking to put together a development team. Contributions to the software by users will also be welcome. There will be a need for new leadsheets, transcriptions, documentation, and even translations of the user interface. Cheer, Raymond

GPL Violation Alert! - I talked with the President of Beat Kangz Today

by Ronald Stewart

GPL Violation Alert! - I talked with the President of Beat Kangz today his name is A.J. and he is a sweetheart and his head is on straight. He is currently going to work on an official statement and he wants to embrace and thank the developers and give the authors credit on their software and materials moving forward. Additionally, Beat Kangz is interested in opening up development with authors to make Beat Kangz even better including funding open source development and projects. I think the hiccup is that they didn't know how to properly thank/engage in regards to GPL and such. It's sounds like more of a noob thing and definitely not a jerk thing. Let's give these guys the benefit of the doubt because their heads are on stragiht. Stay tuned. Much Love. Thank you Ronald Stewart Creative Director Trinity Audio Group Inc. 9854 National Blvd. #322 Los Angeles CA 90034 310-733-9285 ronaldjstewart(a)gmail.com www.indamixx.com

Re: [LAD] [LAU] Python and MIDI orientation for a project

Just to clarify, mididings is primarily intended as a standalone MIDI processor. Usually its sole input/output is MIDI, and it just happens to use Python for its configuration. It's not really a MIDI API to be used in larger Python programs, and I'm pretty sure it completely sucks for that purpose. Now... who's going to finally write proper Python bindings for JACK MIDI? :) Dominic

Re: [LAD] Python and MIDI orientation for a project

by Carlos Sanchiavedraz

Hi Harry. It's curious... you got the point I had in mind :) My main idea is to extend the configuration dialog so that, same as you can map wiimote keys/events to keyboard keys, you could map wiimote keys/events to CCs helped by a select box with a list of available CCs; first maybe a usefull and comprehensive subset and then the whole set in later versions. Maybe we can add the "advanced" section as well. But first I'm trying to get information about the other topics on my list :) Thanks Harry. //On my mobile device.
