[LAD] wav composer not toilet non-release

by James Morris

Hello, After an intensive development of my ten year old project Wav Composer Not toilet, from September 2013 up to the new year, I was intending to make a new release in February, and then March, and then... Unfortunately an official release has not materialized so I'm just saying here is the code, do what the kcuff you like with it. -=-=-=-=-=-= What? Wav Composer Not Toilet is a text based non-professional non-realtime non-interactive modular audio synthesis, sampler, and sequencer by a hobbyist developer scratching an itch which has eased off for now. -=-=-=-=-=-= What's new? The main focus of recent development was intended to create greater flexibility for the user in how modules and 'data objects' are specified within a file. This flexibility allows: * arbitrary ordering of items * optional items * optional groups of items * multiple choice items * self connection of optional inputs This is available in the master branch and can be built like so: git clone https://github.com/jwm-art-net/wcnt.git cd wcnt sed -i 's/DEFS=-ggdb/#DEFS=-ggdb/' Makefile make make examples (the sed command above will remove debugging info that should be removed in a release). After running `make examples` look in the examples/ directory to see what wcnt has done. Wav Composer Not Toilet is hardcoded to use a limited selection of LADSPA plugins and no others, these are: * Bode Frequency Shifter * C* PlateX2 * DC Offset Remover * Fast Lookahead Limiter * Glame Low and High pass filters (+ Butterworth versions) * Single Band Parametric EQ The examples will fail to complete if these are not available. They reside in the C* (formerly Caps) and SWH LADSPA plugin suites. However, in the custom_names branch on github a generic LADSPA module is available which allows specification of arbitrary LADSPA plugins. It is working to a basic extent but unfinished. Carry on. char*s James Morris

Re: [LAD] Input/output error alsa api

by Thiago Carísio

Hi Harry, Do you know if there is some rule to compiling using librtaudio? Because, there is an error..and i don't know what's wrong. I'm using g++ 4.7.2 and i'm compiling using: $ g++<programname.cpp> -o <programname> The error is: undefined reference to 'RtAudio::RtAudio(RtAudio::Api)' i'm including the lib in the program, normally! 2014-03-29 11:11 GMT-03:00 Thiago Carísio <thiago.carisio(a)gmail.com>: > Hi, Harry! > > I don't know...hehe...i'm just was searching for api's and alsa seemed to > be a good ideia.

So JACK was built without ALSA support. What version of Ubuntu are you using? I am unable to believe that 0.121 is the latest version available for any reasonably recent version of that distro. --p

[LAD] (no subject)

by Raphaël Mouneyres

hello, thanks to nama and ML archive, i now know about https://github.com/navicore/Jacks perl api I'm missing a callback to know the current transport position (either in seconds or BBT). Is there any way to get it from perl ? (i'm currently having trouble to make jack.osc doing the same job) thanks, Raphaël

[LAD] qjackctl-0.3.11: desktop notification area support (patch)

by Zlobin Nikita

I use sometimes qjackctl to control transport during work in qtractor, because when in qtractor i open track properties to test various plugins, all other gui is unavailable, excepting only plugins gui. But this ugly popup on closing of qjackctl window is a bit annoying. My final goal was to get it with option like "Don't remind anymore", but even getting messages appeared not very easy. My implementation uses notify-send utility, which in ubuntu is packaged in libnotify-bin package. Arch wiki says, that libnotify is good for both gnome and qt4 apps, but it seems, but basic libnotify api, written on C, is glib/gobject-based, and i can't find libnotifymm (same glib, but on c++) in neither ubuntu nor portage. Though in gentoo i found even some kde stuff, using libnotify %).

[LAD] LA mailing list feature request: more error (denial) feedback

by Zlobin Nikita

I just tried to send patch for qjackctl in uncompressed form, which itself is ≈430Kb, and nothing appeared in archive. I'm sure, that it is due to size limit. However, e.g., on gentoo proaudio mailing list it is usual to send patches and ebuilds uncompressed for easier review directly from mail (mailing list web ui and probably some mail clients even display them as part of message). Since it is first time, when i send some materials to this list, i did as usually. It would be better to have some error feedback - those, trying to write to list without registration at least get feedback about denial.

[LAD] Drums - EDrums - Hydrogen

by Aurélien Leblond

Hi all, I have been using Hydrogen for a few years now, both by programming drum patterns or playing live with an e-drums and there are few things I'm missing... I wouldn't mind having a look into coding them, but I'd like to get the feedback/comments/opinions/screams of despair from the community. HiHat & EDrums Hydrogen only deals with close/open for the hihat control. It should be easy enough to mark the instruments as being part of a hihat and provide for each hihat instruments a range to define which one is triggered. For example close from 0 to 10, half-open from 11 to 40, open from 41 to 127. EDrum sends a cc message for how close the hihat is closed. There is already a script to do something very similar (http://www.hydrogen-music.org/hcms/node/2807) using mididings, but having it in Hydrogen would be more user friendly I guess? EDrums & Cymbal choke I believe edrums are using aftertouch for that (to confirm) - sample could simply be muted? Multi-mics drum samples Drums recording often uses several mic placements and depending how they are mixed it changes the mood of the drums. For example mixing using overhead and direct samples. I have drum samples where: - the snare is composed of under, above and overhead takes - cymbals are direct and overhead takes - kick is front, back, inside - etc... Per instrument, we could have groups of samples: - Instrument would have one fader per group and one fader for the whole instrument - Each instrument group would have its own output - Each group would have its fader - if we have multiple instruments with the group "overhead", this fader can control the gain for the overall overhead - I don't know what to do with panner - would anybody have an opinion on that? - Trigger/velocity (programmed or played live) would trigger would trigger all necessary samples What do you guys think of these proposals? Aurélien
