Is there any way to completely switch off the vertical measure/beat lines in Ardour3's edit window ? Changing the colors to hide them won't do because they are on more than one background. If not, I'd suggest to not draw them when the corresponding bars on top are disabled. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

[LAD] Python Non-Session-Manager Client Module (version 0.1)

by Nils Gey

Dear Developers, I've written a convenience interface to implement Non Session Management as fast and easy as possible in Python 3 applications. It is no magic programming at all, but it makes things just that tiny bit easier that is required to actually implement something, and not only plan it. The real work is to follow the rules of a managed system (see http://non.tuxfamily.org/nsm/API.html ). So implementing the technical side should be a no-brainer to let you focus on the actual task. pynsmclient is open source under the GPL3 or later and can be found on my github page so you can start using it right away. https://github.com/nilsgey/pynsmclient I also have written a short article in my blog about that topic http://nilsgey.de/?id=24 Greetings, Nils

[LAD] [ALPHA] ladspa.m.*

by Florian Paul Schmidt

Hi, after a somewhat productive weekend I'm happy to announce some alpha quality software (i.e. bug ridden, not feature complete) for your consideration and feedback :) But: release early, release often XD I went a little overboard with modularization and separation of concerns, so in the end it became four packages (with possibly one more in the future - a LV2 plugin to load the synths/instruments). Documentation is also very much lacking, but each package contains at lease a single example file to illustrate the usage. * ladspa.m - https://github.com/fps/ladspa.m ladspa.m is a header only c++ library to build and run general synthesis graphs made up out of LADSPA plugins. The interface is kept deliberately kept simple and unsafe, as it is expected that one uses higher level tools to build these synthesis graphs (e.g. using a library on top op ladspa.m.swig or ladspa.m.proto). * ladspa.m.swig - https://github.com/fps/ladspa.m.swig ladspa.m.swig are SWIG generated python bindings for ladspa.m. This allows building and running general synthesis graphs made up of LADSPA plugins from within python. This requires ladspa.m. NOTE: I just saw that the swig interface definition lacks the ability to connect outside buffers onto plugin ports. This will be fixed in the next few days.. * ladspa.m.proto - https://github.com/fps/ladspa.m.proto ladspa.m.proto contains google protobuf definitions for general synthesis graphs made up of LADSPA plugins. It also contains a definition for an instrument file format. This library does not depend on either of the two above. It becomes useful with the last package (ladspa.m.jack) and possibly in the future with an LV2 plugin to load and run these (to be announced when done). The python bindings generated for ladspa.m.proto can be used to generate synth and instrument files that can be loaded by ladspa.m.jack. The instrument file definition allows for polyphony while at the same time putting no constraints on the inner structure of the instrument (each voice is made up out of plugins, they can be identical or not between all voices).. An example is included which defines a simple sawtooth instrument with exponential envelopes and with 5 identical voices except for a different delay setting on each voice. https://github.com/fps/ladspa.m.proto/blob/master/example_instrument.py Pipe its output into a file called e.g. instrument.pb. This you can then load into ladspa.m.jack.instrument. Here's a little example of the generated instrument file loaded into ladspa.m.jack.instrument and playing a little 120bpm loop (from ardour3) with it: https://soundcloud.com/fps-2/t-m This also highlights the need for a higher level interface on top of it to ease the process.. * ladspa.m.jack - https://github.com/fps/ladspa.m.jack ladspa.m.jack is a library which allows loading ladspa.m.proto synth and instrument definition files into jack hosts that are provided as example clients. ladspa.m.jack.synth allows loading a synth definition file and run it in the jack graph. ladspa.m.jack.instrument allows loading an instrument definition file and provides a midi in port which allows playing the synth. But like I said this is all ALPHA software and I just announce it because someone else might have fun with it. Please report all issues that you find either per email to me, on LAD or LAU or on the issue trackers of the github projects.. Have fun, Flo -- Florian Paul Schmidt http://fps.io

[LAD] Is dynamics interpolation available in linuxsampler?

by Nikita Zlobin

Last time i tried to make a roll with G-Town Church Bassdrum, but it appears ugly. Did not try to humanize timing, but expecting it much better with interpolation. May be, it is some hidden feature, which is not used in most freeware gig and sfz banks?

[LAD] A request for a simple app

by Alex Stone

I've been working with large lscp files, over a hundred .idfs for muse 2, etc, for sometime now, and i'm pretty well knackered from manually creating large monolithic instrument config files of some sort or another, for the same sample library set, across apps. I propose the following, and i'm wiling to put some money in someone's pocket for this: A simple app (CLI is ok but GUI based preferred) that: 1) automatically converts lscp files containing single or multiple midi instrument maps into individual midnam files. 2) automatically converts muse2 .idf files into midnam files. 3) converts midnam files into muse2 .idf files Obviously needs to work properly, and create correct ( auto app checked) midnam and .idf files. App needs to be opensource (obviously), and public, for those other poor souls who have to struggle with large instrument files, particularly those using large sample libs with copious articulations per instrument, and for whom automation of these excruciating data processing tasks would save massive amounts of time and effort. Thanks, and if you're interested, contact me privately, Alex Stone.

[LAD] JACK latency chart

by Joel Roth

Hi all, I once saw a helpful chart showing how latency propagates through the JACK graph, through the capture and playback ports of each node. Can anyone provide a link? I want to make sure I understand correctly, that my app's latency callback should be checking capture latency at the input ports and setting playback latency on the output ports. Thanks, Joel -- Joel Roth
