Re: [LAD] Yoshimi Midi Learn: 1st testing release
Hi Renato, it's me, licnep, i just recently joined this mailing list after the post about the midi learn branch of yoshimi. Thanks for the feedback. My midi learn branch is built on top of the new 0.62 branch (that will be the next official yoshimi release) so some of the changes you see are not made by me. For example about the UI i only changed the way knobs look and, of course, added the midi controllers window. In particular i agree that I don't like the fact that you have to right click to edit an instrument, i find it counter intuitive, even after a lot of time of using it i still get it wrong, so i hope it will be reverted back to normal before the next release. As for the annoying scale bug, i think it was corrected in the previous 0.60 branch, maybe the correction has just not yet been added to the 0.62, but it will, i think. I haven't yet personally asked for a merge, the code is not really ready yet, and the main devs don't have much time to review it now. Anyway i hope the midi learn feature will join in the main branch sooner or later, it was not my original intent to create yet another fork.

Re: [LAD] Android audio plugins
Hi, Reading this thread again, I feel like clarifying a few points. On 06/29/2011 10:03 PM, Nick Copeland wrote: No, technically, an app can load a native shared library provided by another without caring about any kind of signature. An app can freely dlopen() a library provided by another app. Hm, are the issues related to that library being in an APK? I don't see how you can have Android give you access to somebody else's library unless you have been signed with the same private key. If you are saying 'technically' accessing system libraries then I agree but in that case you have an issue with distributing the library as you cannot distribute system libraries via the Android processes. You are confusing a real lot of things here. The APK package signature have nothing to do with accessing another package data files or libraries. I am not talking about accessing system libraries. I am talking about one application accessing the shared libraries provided by a third-party application. When an application gets installed, the Android Manager installs the libraries that it provides into the application data directory, in the lib/ subfolder. And these libraries are world readable and executable. In the past I was also puzzled by this, and thought it was risky to rely on it, but I discussed this many times on the android-ndk mailing list, with Android lead developers, and it came out to be reliable. These are not suppositions. There have been numerous discussions. And here's the conclusion about accessing another app's libraries, by Dianne Hackborn (a Software Engineer who sits very near the exact center of everything Android), answering my questions: http://groups.google.com/group/android-ndk/msg/05aae4aafb266cf1 Now, on Andraudio, I have indicated that there's a security issue. Indeed, Dianne insists a lot on the fact that altough loading and running a third party .so is absolutely feasible, it happens at 100% under the responsibility of the app which executes the code. What this means is that, if an app loads a malicious plugin, then it could be reported as a malicious app, and be banned from the Market, etc... Perhaps I have missed the point, Android security prevents you accessing resources that you have not been given a priori permission to use to ensure the system cannot be compromised by malicious code. If you want to root your device and hack it to get to the point where you can overcome that security then that can be achieved but that comes back to another point I made: Yes, you misunderstand the permission system and the Android security model. I'm not implying any kind of rooting and all that. I'm talking about plain non-rooted standard Android. On Android, the security model regarding applications is based on sandboxing. Such sandboxing in turn relies on the fact that each application gets assigned a unique user ID. And permissions (internet access, sdcard write access, etc...) are bound to the user ID. Reading data from another application directory or APK is not affected by this permission at all. Actually, preventing such read access is considered futile: http://groups.google.com/group/android-ndk/msg/15a412a317a034bf But this doesn't allow a given application to perform what another application has the permissions to do. App A can read/execute the data and code provided by app B, but it doesn't grant the permissions of app B to A, because of user ID sandboxing. For this very purpose, an application can actually define custom permissions, that third party apps have to request explicitly (and the user agree), so that another app can for example call a restricted remote API through (Binder) IPC. -- Olivier ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

This will give the community a very good chance that many apps will get JackSession support soon (or later). However, it's still reasonable to expect that not all LAD applications are going to be patched with JackSession support. In other words, there are and will be apps which might be useful (for one or more of us) to use in a session but which won't have JackSession (JS) support. From a users perspective, it would be very useful to be able to use that application (without JS support) in a session in some way nevertheless. At the moment one Session Manager (SM), Pyjacksm (Qjackctl will follow soon, and also Patchage I expect) makes this possible by manually adding 'infra clients' to a configuration file, .pyjacksmrc. See example below. Infra clients are designed for applications without a state, like a2j. But it is also possible to use apps without JS support as infra client. Amsynth is an application without JS support and in this way I am able to load amsynth, with project A. The SM makes sure that Amsynth is started and that the Jack connections are restored (that's the only thing the SM can do for you for apps without JS support). But I don't want to use Amsynth with Project A always (Session 1). I might be working on a totally different project and want to make a session for that also (Session 2). This time I want to load amsynth as: amsynth -b /home/user/projectB.amSynth.presets (I don't use Session 1 and 2 together in this example). To be able to load Session 2, I have to edit my .pyjacksmrc file or make symlinks. *Feature request*: It would be nice if the SM could provide me a way to load a different configuration file. For example: JackSessionManagerX --load configurationfileSession2 Thanks in advance, \r I think I have mentioned it before somewhere, but another good feature for a Session Manager would be the possibility to start (and / or use?) a session via the command line. Like: qjackctl --session session1.session or something. In Qjackctl, the save button in the session window, works as 'save as' atm. A real 'save' button would be nice (saves time).

Would you believe, how cumbersome it's been to track, follow and install LV2 releases ? (The same unfortunately applies to some of your other apps, ingen, ...) Unreleased is unreleased. On purpose. Unreleased things are not *supposed* to be as widely distributed as released things, because they are not stable. Stable in this case does not mean it might crash, it means that everything related will break catastrophically in the future. They are not useful unless you are a developer seeking to participate in the implementation of a new extension, in which case you use SVN. There are all sorts of things in that repository that are rotten crap and most definitely should NOT be widely distributed and used. If it was release suitable, it would be released :P Extensions are not released until there are at least 2 independent working implementations of them. I think most would agree this is a good rule. For users, there are tarballs of all released extensions, and packagers have been doing their thing nicely with them.

Plugins are written by diverse authors in diverse languages with diverse build systems. That's sort of the point. Anyone is welcome to create a meta-package, though, and it would be nice in some cases, but that is a much more messy task than doing so for extensions, since there is no standard format for plugin sources (nor could there be). The scope of plugins is much wider than this wish implies. For example, LinuxSampler is a known LV2 plugin these days. Ingen will be as well. Including these things in such a release is clearly inappropriate. I think actively maintaining, hosting, distributing, and guiding the development of *extensions* is a job that lv2plug.in should strive to do, to keep the LV2 ship sailing straight, so to speak. Plugins, however, are independent projects. The point of a good plugin specification is to enable independent developers to implement whatever plugins they see fit. Centralization is not a win.

My thought: If there was a central collecting point, most maintainers could simply download one tar and make the content ready for their distro.
