Recorded in Linux: restored from archive: KillVideGill

by jonetsu＠teksavvy.com

Hello, This one dates from 2006. The date is easy to remember since it is in Wikipedia. September 13th 2006. The Dawson College shooting in Montreal. It could have been any other at any other place. That evening I made this and almost uploaded it on the killer's web page which was still active at that time, to share the feelings to anyone touched by this. It is about sadness, expressed against a busy backdrop of events. This is entirely done using Zynaddsubfx synthesizer. The sequences are made of 1 short clip each copy/pasted for the duration of the 1:48 piece. The resonance line and chords were played over. What was done this month was to restore the sequence of clips from an old Ardour session that would not load as it was, by copy/pasting and aligning each clip carefully one after the other. Then Robin Gareus' 4-band EQ was applied to all tracks including master. A touch of reverb was added, as well as echo at one place. The original piece was on-going all the same from the start. This new version has a break near the end that surfaces what would be the expression of sad emptiness before the 'business' restarts. Automation was used on EQ and echo as well as here and there for slight volume control. https://soundcloud.com/nominal6/killvidegill

Hint for people with no HDMI sound.

by james

I have a PC with an AMD APU chip, and I'm trying to send sound to my Audiolab 8200AP processor over HDMI. The system is 'Ubuntu Studio 15.10'. I believe the hardware works - I can boot into Windows 10 and send audio from jriver. With Linux, however: - aplay -L does list the hdmi:Generic device, and pulse is using it - Pulse Audio volume control does detect whether the HDMI cable is plugged in at both ends - speaker_test -c 8 -D pulse loops continuously and thinks its playing - Pulse Audio volume control shows the ALSA plug-in [speaker-test] stream However, the Audiolab is stubbornly said the channel is 'silent' on its display. And then I used 'Settings/Display' to select the 'IAG 6"' and select 'use this display' and to mirror the displays - the computer is actually displaying on an attached VGA monitor. And that made things start to work. Ideally I would only access the system over xrdp - but you can't enable the extra monitor without being on the console. Quite possibly I would not have had the issue if either the display was running through HDMI or the VGA monitor was not plugged in - but it is worth bearing in mind if you are having issues. I guess it would be handy if the display on the volume control could indicate 'plugged in but output is inactive' - or (better still) if the HDMI output were active if either the display or sound system wants to use it, and the display is just an unchanged or black background.

Minor bug-fixes and accessibility improvements of GSequencer 0.6.23

by Joël Krähemann

Hi all Advanced Gtk+ Sequencer release 0.6.23 has defenitily not to be missed. Fixes done so far: * fixed allocation of AgsDial * fixed focus in ags_dial.c * fixed _File mnemonic in menubar * fixed recover of GSequencer project as doing properties * fixed SIGINT while reading XML files including AgsRecallLadspa see ChangeLog for indept view. Further on http://gsequencer.org is an empty project with one drum and two synths connected by a mixer with output panel. So you just have to fill in the gaps. Further the mixer is using LADSPA caps plugins: * drum -> 10 band equaliser * matrix0 -> Mono Phaser * matrix1 -> Noise Gate Would be great to hear from you ... $ wget -c http://gsequencer.org/ags_drum_and_synth.xml $ gsequencer --filename ags_drum_and_synth.xml cheers, Joël

Music Recorded With Linux. 7 step

by set

Hi List! I made a few tracks recently. It's all digital hardware that do not need to be advertised on this list until they open up the source. ;) However, it is recorded in ardour on Ubuntu Studio using a Terratec 88 firewire rack. The one i want to share with you is an instrumental beat in some sort of 7/8 tempo, which was quite a bit of a hustle to accomplish on a very square 64steps stepsequencer. (you will here elements grinding against the rest in a traditional 4/4 on the floor). The genre is some sort of .... cat-hop ballade? You be the judge :) http://sakrecoer.com/music/7step.html (WARNING! music start on page-load) I know the sound is a bit dirty and in-ya-face, I am afraid the truth is that the weakest link in this production-chain is the author, namely yours with kind regards, Set Sakrecoer

Yoshimi 1.3.7.1

by Will Godfrey

A minor bugfix on a low profile release. Yoshimi 1.3.7 is another consolidating release. Nothing dramatic, but general usability enhancements. Probably the most significant one is that command line access has moved from being a proof of concept to a real usable feature. It still has a long way to go though. A nice addition to the gui is that significant window locations are mostly remembered now which makes organising your desktop just that little bit easier. Yoshimi source code is available from either: http://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[CyberSoul] - pinGnu

by public＠sakrecoer.com

Hi list, Made this little jam about a little Pingu, riding on a Gnu, contemplating the world from the freedomgalaxy while singing: I'm a little Pingu, riding on a GNU. Looking at the world, looking at you. Free at the core, i wonder why don't you, Look at me the way i look at you. It would be so nice, if you could take me in. Your computer and i could change the world we're in. Your freedom is being diluted. And your code is being polluted. I'm a big GNU with my little Pingu, Looking at the world, looking at you. Free at the core, i wonder why don't you, Look at me the way i look at you. It would be so nice, if you could compute. Your freedom is not to dilute, Someone has taken your tool into dispute, This is what together we should refute. http://sakrecoer.com/music/PinGnu.html Hope someone finds it soothing. Yours, Set Sakrecoer

Alligning audio without graphics (for phase inversion cancellation)

by F. Silvain

Hey hey, it's easier to describe the problem I think. I hae two pieces, one the song with vocals, the other the exact same song, but only the instrumental. Now I'd love to isolate the voice by alligning them and mixing them with one having inverted phase. Since I can't see, and apparently often instrumentals don't start at exactly the same time, I need a way to synchronise those tracks. time shifting by hand is very tedious and hasn't yet yielded a perfect result. There are other issues, which can cause "confusion", so I'd like to get this one out of the way. Does anyone know of a way to do it from the commandline? Sometimes alligning the beginnen of a piece (the onset of sound) might do, but sometimes it's a little more complicated. Anything from Sox to Csound will do. :) I appreciate any hint in the right direction! Thank you!

Mono tracks to mono or stereo bus ? And sampling rate

by jonetsu＠teksavvy.com

Hello all, When having multiple mono guitar tracks in Ardour and wanting to regroup them in a single bus, would that bus be preferably mono or stereo ? How is this in relation to eventually placing the guitar bus in a stereo field ? Also, is it possible in Ardour to raise the sampling rate of single tracks ? I just followed the part of the Brian Bollman music production (free) course about sampling rates. The higher the rate the more fidelity to the original signal and also the more material to work with when bringing it down to CD or ogg/mp3 level. I would like to try with the guitar and bass tracks as I don't care so much about synths for now. Is it possible to tell Ardour to work with a higher sampling rate for a track ? I don't seem to have found the option. Cheers.

Qtractor vs. dssi-vst?

by James Harkins

I read on some sites that it should be possible to use VST plugins with Qtractor by way of dssi. On my system, Qtractor depends on liblo7 and dssi-vst:i386 depends in liblo7:i386. If I install dssi-vst:i386, I cannot install Qtractor. If I then try to install Qtractor after that, it will uninstall dssi-vst:i386. So... what does one do to handle this? FWIW, I've also tried LMMS's Vestige. There is some graphics bug with particular plugin I need to use, rendering it unusable. So I am in an emergency situation looking for alternatives. hjh
