by Rui Nuno Capela

Howdy! Modesty on the side, this is the ultimate Qstuff* End of Summer'16 release frenzy. Nothing less than the following gems: * QjackCtl 0.4.3 * Qsynth 0.4.2 * Qsampler 0.4.1 * QXGEdit 0.4.1 * QmidiCtl 0.4.1 * QmidiNet 0.4.1 are now released to the masses.

Calf plugins, setting defaults

by Bill Purvis

Hi folks, I've been playing with the Calf Fluidsynth plugin, but whenever it starts up I haven't been able to find a way to set the default patch set. I have to go through the full selection rigmarole each time. I'd like to be able to set this up automatically, and I'm sure there must be a way. Anyone have any guidance on this? Many thanks in advance, Bill -- +----------------------------------------+ | Bill Purvis | | email: bill(a)billp.org | +----------------------------------------+

LADSPA Plugins from ALSA,would like some help, please !

by bricolodu

Hello, Im trying to implement a kind of MAXXBASS plugin on an headless machine (running in mono). If it works, I would be happy to share it if someone is interrested. However, to do so I need some help to better understand the LADSPA syntax.

Yoshimi - trying to help newbies

by Will Godfrey

Right from V 0.016 we had the default MIDI and audio set for Jack, and soon after that we abandoned the beginners Gui option. Since then a lot has changed, and I'm wondering if we should reappraise these decissions. Fairly recently we gave a nod in the direction of helping beginners by making the virtual keyboard appear alongside the main window on a very first time startup. Personally, I think that's better than a dumbed down Gui. These days, we also have the short Yoshimi guide that tries to get new users started. Now I'm wondering if we should change the first-time startup to an all Alsa configuration. It would make no difference to existing users, as for quite a while these have been re-settable preferences, and are stored in the config file. Would it get us closer to a 'just works' position? -- 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.

Ardour 4 audio export FLAC questions

by Alf Haakon Lund

Hello list, My googling did not provide me with sufficient answers, so I'm directing my questions here ;-) I made a 1 hour long project in Ardour that exports as a 635 MB wav-file. From Ardour the same project exports as a 566 MB FLAC file. However, if instead I use SoundConverter to convert the WAV to FLAC, the resulting file is 269 MB. Since both are FLAC I'd expect them to yield the same playback (though after finding a report at hificritic [1], I wonder...) Is there a way to check if those FLAC files are indeed 'audio identical'? And, obviously - if the audio quality is indeed the same - I much prefer the smaller file. How can I tell Ardour to compress better? Thankful for any and all input, Al F 1. http://www.hificritic.com/flac-wav-sound-quality-research.html

Music made with Linux - Ordo

by Brendan

Hey there, I recently wrapped up a short album I've been working on: http://desertreceiver.bandcamp.com/ The music is instrumental & electronic, and sometimes it veers into more noisy territory. These tracks were first created in Renoise, and then I used Ardour for mixing the final product. There are quite a few sounds from both Yoshimi and from my hardware synth, and I used a variety of plugins that come with Ubuntu Studio, including the Calf plugins. Enjoy.

Music made with LMMS

by ycollette.nospam＠free.fr

Hello, Here is a new "album" made with LMMS: https://www.jamendo.com/album/160826/extreme-limite-de-la-sagesse All other albums are also made with LMMS: https://www.jamendo.com/artist/471813/joseph-curwen/albums I used version 1.1.3 with some patches to enable the Carla rack under LMMS. This package and others are available in this repo: https://copr.fedorainfracloud.org/coprs/ycollet/linuxmao/ This repo works for Fedora 23 and 24. I used samples from: - https://archive.org/ - http://freesound.org/ - http://wiki.laptop.org/go/Free_sound_samples (percussion samples) I feel LMMS is a great tool to play with sounds and I am glad to see that there are still some work done for a new release ... There are some encoding problem on Jamendo. I send them several messages to highlight these problems, but still no answer. So, if the sound feel a little bit strange from time to time, it's maybe a jamendo problem (or this is maybe due to the song :) ). Best regards, Yann

DAW file format

by Alf Haakon Lund

It seems to me that most DAWs on linux are 'operating on' WAV files. However I see there are other options, like in Ardour's session/properties/media tab Except for losing the 4 GB limit on file size, are there other advantages of using for example broadcast rf64? Will Ardour just change the default once I change this setting, and is it safe to change on a work in progress? Regards, Al F
