Lisalo - Linux Sampler Loader - is a command line program that loads entire directories of sample files, a single .sfz file or takes instructions from a meta .lsl file with relative paths to samples. Now you can quickly and easily load sampled instruments without even starting a GUI. This is release 1.4, grab it here, no installation required git clone git://github.com/nilsgey/Lisalo.git [New Features] -Jack Autoconnect-Port for the stereo sum/mix channels can be given from the command line -Can start Linuxsampler with a given server-address and port, which makes multiple instances possible -Jack Midi In for autoconnection is a commandline parameter. There is only so much you can implement into a tool that aims to be small by design. This marks my "feature complete" milestone. Future releases will be bugfixes. One example what you can do now: I use it to load the Salamander Piano shortly after boot and connect it to my ALSA midi port (which is always on, no matter if the keyboard itself is switched on or not). I now have instant piano sound whenever I switch my keyboard on. It does not conflict with other lisalo or Linuxsampler sessions. With this lovely one liner: /usr/bin/lisalo /home/nils/samples/sfz/SalamanderGrandPianoV2_48khz24bit/SalamanderGrandPianoV2.sfz -m alsa_pcm:Hammerfall-DSP/midi_capture_1 -p 7777 -m Salamander > /dev/null [Contact] https://github.com/nilsgey/Lisalo info@... irc.freenode.org #laborejo Feedback and chatting are welcome!

Praxis LIVE screencasts / good screencast software for audio?

by Neil C Smith

Hi All, Firstly, finally got around to some screencasts of Praxis LIVE in action - http://praxisintermedia.wordpress.com/2012/07/30/video-rough-cuts-1/ These are just 'rough cuts', unedited except titles and no voiceover. Only first 2 have audio, and the audio on the second is a little off in places (see below!) Secondly, anyone got a suggestion for screencast software that's good at glitch free audio? These are done with Kazam. First is mostly OK, but the second is a little glitchy. Finding only about 1 in 4 captures is any good - all sorts of weird glitches and sometimes speed issues, though the audio playback while recording is fine.

[Android|OT?] CamSynth - Just an experiment

by Florian Paul Schmidt

Hi, I don't know if this is on-topic or off-topic - technically it runs on a linux, but then, maybe, just, no, no Android on LAD?? :D But anyways: I played a little with Android Development and hacked up a little experimental Synthesizer app. https://github.com/fps/android_camsynth https://play.google.com/store/apps/details?id=io.fps.camsynth It's free and open source and renders 8 voices (on my LG-P500) with a trivial (and wrong :D) synthesis method where the voice gains are determined by the camera image at a 8 x 8 px resolution.. I guess it's somewhat a minimal project which can be instructive to some (the synthesis part is implemented in C via JNI). And the code is very small.. Have fun, Flo

Leslie and convolution

by Julien Claassen

Hello everyone! I have just asked myself, if it is a good idea to use an IR of a Leslie for simulating a Leslie. Correct me, if I'm bloody stupid, but working on the basics of convolution, it doesn't look promising. Since you take the IR of the Leslie and then apply the full IR to each sample, meaning, that you might get more of a whirling reverb? Or is there another technique, to apply an IR and cycles. Just one "sample" of the IR to one sample of the input signal. If I am completely wrong, a simple no will suffice. My knowledge of this is basic. I've only got some knowledge from a lecture called "signal theory' to back me up and it should probably be called "an introduction to" or "basics of" at that. :-) Warm regards Julien =-=-=-=-=-=-=-=-=-=-=-=- Such Is Life: Very Intensely Adorable; Free And Jubilating Amazement Revels, Dancing On - FLOWERS! ====== Find my music at ====== http://juliencoder.de/nama/music.html .....................................

"It's beyond the pale that we today have all the communication technology Gene Roddenberry (August 19, 1921 – October 24, 1991) just could dream about, but the way it could be used today is weak." +1000. I would not say I am against Twitter, rather against all those patents and copyrights that just keep us in the dark ages of digital technology.

samples/symlinks/sessions

by James Morris

Hi, My sampler app has Non Session Mangement implemented but is currently still referring to external files by their original path. I want to use the symlink method as discussed fairly extensively here but I'd like to know if there is any recommended strategy for naming the symlink of a sample. It could so happen that as far as the filesystem is concerned the only discerning uniqueness between two samples is in the path (ie kit1/snare1.wav and kit2/snare1.wav). I've come up with three possible solutions to this (in my current order of preference): 1) symlink-to-sample created in a subdir named using a hash* of the full path to external file 2) painstakingly re-create the full path within the session dir and add the symlink into that. 3) some horrible text manipulation of the full path (ie replace / with _) that is bound to fail. * J. Liles mentioned SHA1 here: http://linuxaudio.org/mailarchive/lad/2012/3/30/189343 Are there other/better options or disagreements about (1) being a good choice over the other options I've presented? cheers, james.

Re: [LAD] setBfree - Fast Leslie is weird...

by Robin Gareus

Hi Fons, I've taken this to LAD, since it's not really a user issue.

Could it be that you've also accidentally sent other MIDI-CCs to setBfree that changed the Leslie's behaviour? The wobble (wrong octaves?) is not unexpected for two independent doppler-shifts and is also present in the real thing(TM). Yet, the Lesie is currently indeed the weakest link in the whole emulation. You're correct in saying that it is wrong. Yet, IMHO it still does sound OKish. It's implemented as a combination of angular dependent IR - measurements of the horn made at CCRMA [1] - which are also [incorrectly] used for the baffle. Plus the optional static IR to add the [feel of the] cabinet - which is also wrong, buts sounds good nonetheless :) - I'm hopeful that we'll get our hands on the IR measurements made for [2] which will make this 2nd stage obsolete. The acceleration is also not [yet] correctly implemented. I'm about to fix this with information provided in [2]. Even though it does sound kind of weird. I prefer it to the mdaLeslie or similar effects which are far too clean. YMMV. Your criticism is just and appreciated. Please bear with us - I suppose that we'll eventually end up rewriting the effects which carry a lot of legacy code. -- If you can spare the time a DSP expert like yourself would be very welcome. Anyway, one step at a time, robin [1] https://ccrma.stanford.edu/~jos/doppler/dafx02.pdf [2] http://www.aes.org/e-lib/browse.cfm?elib=15120
