Thanks guys! I actually tried j2a but now i realise that i forgot the -e option to expose the hw ports. Doh! I'll give it another try tonight. Thanks!

FFADO is a backend that you can run JACK on top of. If you run JACK with the FFADO as the "driver", then JACK will be able to send MIDI commands to your Saffire. ALSA MIDI is a totally different "MIDI". The upside: There's a program "a2jmidi" which will put all your ALSA MIDI ports into the JACK MIDI graph, then you can connect any ALSA MIDI out to JACK MIDI in, and vice versa. "a2jmidid" is the name of the package on debian based systems. Running is usually most benificial like so: a2jmidid -e & so that it keeps scanning the ALSA MIDI graph for changes, and will update the JACK MIDI ports available. Good luck! -Harry On Thu, Dec 8, 2011 at 9:57 PM, thijs van severen <thijsvanseveren(a)gmail.com> wrote: > > > > Hi all > > > > i'm trying to use 'amidi' to send a simple midi message to the midi out > port of my fi... > _______________________________________________ > Linux-audio-dev mailing list > Linux-audio-dev(a)lists.linuxaudio.org > http://lists.linuxaudio.org/listinfo/linux-audio-dev > >

[LAD] FFADO midi ports

by thijs van severen

Hi all i'm trying to use 'amidi' to send a simple midi message to the midi out port of my firewire (FFADO backend) audio device. a Saffire LE. to do this i simply need to specify the port i want to send the data to, however i can only select one of the ALSA midi devices listed under /dev/snd/ and the firewire midi ports are all Jack midi ports and thus not listed here. but where are these listed ? or should i be doing things differently ? grtz Thijs -- follow me on my Audio & Linux blog <http://audio-and-linux.blogspot.com/> !

[LAD] AMS LV2 0.0.4

by Aurélien Leblond

Hmmm, that's a weird one! My only explanation is that you have the file /usr/lib/pkgconfig/lv2-plugin.pc but not /usr/lib/pkgconfig/lv2-gui.pc... Could you check on your system? Btw, what distribution do you use? >From my side, I'm not even sure I need to check for both libraries in my wscript... As you said, they come from the same lv2-c++-tools package. Thanks for the feedback anyway :) Aurélien

[LAD] Ardour3 - strange problem

by Fons Adriaensen

Hello all, Trying out Ardour3 but I'm blocked... I deep-copied an existing A2 session, paradiso-2, to /audio/ardour3-sessions. But A3 complains that it can't find the audio files in /audio/ardour3-sessions/paradiso-2/interchange/paradiso-2/audiofiles which is the right place, and the files are there. ??? -- FA Vor uns liegt ein weites Tal, die Sonne scheint - ein Glitzerstrahl.

[LAD] NASPRO 0.3.0 released

by Stefano D'Angelo

Hi all, I'm glad to announce the release of NASPRO 0.3.0. NASPRO (http://naspro.atheme.org/) is meant to be a cross-platform sound processing software architecture built around the LV2 plugin standard (http://lv2plug.in/). The goal of the project is to develop a series of tools to make it easy and convenient to use LV2 for sound processing on any (relevant) platform and for everybody: end users, host developers, plugin developers, distributors and scientists/researchers. This release introduces a new simple command line effect processor using LV2 plugins called LV2proc, adds experimental translation of DSSI programs to LV2 presets, breaks the API of lower level libraries to make them slimmer and more efficient, and includes as usual bugfixing and improvements here and there. You can find detailed ChangeLogs in the tarballs. It includes: NASPRO core: the portable runtime library at the bottom of the architecture; NASPRO Bridge it: a little helper library to develop insert-your-API-here to LV2 bridges; NASPRO bridges: a collection of bridges to LV2 which, once installed, allow you to use plugins developed for other plugin standards in LV2 hosts; LV2proc: a simple command line effect processor using LV2 plugins. In particular, the NASPRO bridges collection includes two bridges: a LADSPA (http://www.ladspa.org/) 1.1 and a DSSI (http://dssi.sourceforge.net/) 1.0.0/1.1.0 bridge. NASPRO core, NASPRO Bridge it and NASPRO bridges are released under the LGPL 2.1, while LV2proc is released under the GPL 3. Enjoy!

[LAD] AMS LV2 0.0.4

by Aurélien Leblond

Hello everyone, I just posted a new version of the AMS LV2 plugins: https://sourceforge.net/projects/avwlv2/files/latest/download The main change from the version 0.0.3 is a embeded GUI for the VCO. As a reminder, these LV2 plugins are a porting of the AMS internal modules designed to be used in a modular synths (especially Ingen). At the moment, the Analog Driver, normal and Advanced Envelop, Amp, LFO, Mixer, Noise2, Slew Limiter, VCA (Exponential and Linear), VCF and VCO2 have been ported. This should be enough to be able to create basic patches, and two presets for Ingen are available in the package. Testers, comments, feedback....everything is more than welcome! For the ones who wants to create LV2 plugins, the code is written in C++, using Lv2-C++-Tools and GTKMM (the GUI designed with Glade). The code is quite simple, making them examples on how to mix all these things together and be able to design LV2 plugins quickly... Aurélien

[LAD] Cue2ddp Release 0.8.3a

by Andreas Ruge

Hi, I'd like to announce version 0.8.3 alpha of some DDP mastering tools I've written for Linux. If you are interested, and especially if you have other software which reads or writes DDP please test! I'm not a professional C programmer, but a recording producer, so I appreciate any input! http://ddp.andreasruge.de Cue2ddp converts cue/wav CD images into DDP 2.0 images, the format that plants often use internally to drive their glass mastering process. So when using DDP instead of an audio CD plants will usually not mess around with your project anymore, but just press what you send them. (Which can be a good thing.) Aside from the software mentioned I'd like to find out what people think is the best workflow for final CD mastering including DDP. By having cue2ddp as a stand-alone program, it can be used with all programs which can export cue/wav. Is that flexible enough, would you want other input formats? Or would you rather want to see an interface which can be more tighlty integrated into ofther software? Let's say cue2ddp would accept cue sheet *and* audio data from stdin, then any software could simply pipe into it. Very low tech, I know, but reading the DDP license I'm not sure if I can release a proper DDP library as open source (let me know if you think atherwise: www.dcainc.com). Also while we are at it, is there any need for other (proprietary) CD image formats, like .pmi (Pyramix Workstation), or JAM on OSX?

[LAD] for samplecat's dev

by Renato

Hello, is the samplecat dev on the list or does someone have his mail? The feedback form on http://samplecat.orford.org/ is broken and I leaved a comment some days ago, which is still waiting moderation, and I fear it got lost. best wishes, renato

Re: [LAD] Linux Audio Documentaion Effort : (Was "Question 0")

by thijs van severen

Documenting (code) is always a good idea. Its hard enoug to find and motivate people that have good coding skills, so the last thing you need is for those people to get frustrated while trying to find out where/how they should start. Transparent, error-free documentation, website and active mailing list are key here! I dont have coding skills, but if you need someone to help with the documentation as such, i'm willing to help.

I'd be happy to do some contributing too, but like Harry,... Hi, a great idea! I'm sure that you will see valuable feedback from this list if you publish your tutorial, imho this ensures a good quality. Do not discuss to long over question like the correct toolkit. Those can lead away too easily from the core problem.
