John Option: Where is my car? - New song and new Ardour project available

by Massimo Barbieri

Hi, today we have published the video of another single of John Option: Where is my car?. The song is published under the terms of the Creative Commons License (CC-BY-SA) and it's completely produced with free software: Ardour, Hydrogen, Jack, Qsynth, CALF, and many other great free audio software that we used under Debian GNU/Linux. Here you can listen the single and see the video (made with kdenlive): https://youtu.be/mj3qrMQZIHk As for the previous songs we have done a little more in the direction of freedom and we published in our website[1] the single recording tracks and the complete Ardour session. All this material is published under the terms of the Creative Commons license Attribution Share alike so that anyone can use our tracks to produce a remix of our song or even a new song that have to be published under the same license. You can find all about our project here: http://johnoption.org I hope that you like our choice of freedom. If you feel like I'd love to read your feedback, because the encouragement of the people who listen to us and appreciate the philosophy of our project is the only fuel for us to continue. And if you like to be updated about our next release, please subscribe to our YouTube channel or any other social network you like (see link to our profiles on our website[1]).

Latency tests (not really... it's music)

by Lorenzo Sutton

So I was doing some latency tests with jack and realtime kernel... But the email isn't related to kernel, hardcore realtime settings, etc. Sorry :-) Wile testing I hooked an old Pd patch I had which simply generates random pentatonic notes to Yoshimi. Totally forgot of the tests I had planned, added just a bit more randomness, added just a bit more release to a couple of yoshimi voices and this came out (yes also some (lots of) reverb). https://soundcloud.com/lorenzosu/latency-test-random-pentatonics-with-pd-an… I'm always rather impressed by the sound palette and control Yoshimi offers... Lorenzo. PS: Overall no massive xruns so latency looks good for now - :-)

mcpdisp 0.0.1

by Len Ovens

For those of you who use a bcr2000 or other control surface with no display and miss the 55x2 display that the Mackie Control has. This utility provides that display. It can fit quite nicely at the bottom of the screen under the Ardour mixer or editor window. http://www.ovenwerks.net/software/mcpdisp.html This the initial release on which I learned how to use the jack ring buffer. I use this with my $3 midi controler http://www.ovenwerks.net/hardware/index.html -- Len Ovens www.ovenwerks.net

Focusrite Saffire Pro 40 - reliable?

by Ben Bell

Hi all, My dual Delta 1010 setup is on its last legs and I'm thinking (again) of retooling with a Saffire Pro 40. I've been bitten in the past by upgrades like this which is why I'm still on the 1010s, but there's only so many times I can repair them before I have to admit defeat. Is anyone out there actively using a Saffire Pro 40 in a serious setting? Is it reliable for low latency, with all channels working at once? Does it work with any recent ffado, or do you need specific versions, patches or anything else? I've read plenty of vague comments about which firewire chipsets might be good or not, but are there known-good PCI Express firewire cards that are a sensible price and work well? I'm really hoping for "Yes, I've been using one for a year and it's rock solid," rather than "I've googled and it claims to be supported," or "Yes, it's fine if you pull the latest beta7 branch from git and only use Acme 2000 firewire interfaces." Sorry to sound unduly cautious or skeptical ;) In short, if I bite the bullet, retire my Delta 1010s and buy a Pro 40, are the drivers and tools now at the stage where I reasonably expect to be up and running again in a day rather than still fighting problems a week later? Cheers, bjb

First multitrack project: midi tracks and plugins

by Ivan K

I have a 5 minute four channel midi file that I essentially want to orchestrate and add a spoken audio track to, and perhaps add a few other audio tracks. I first began experimenting on this file with qtractor. One thing I would like to do is to switch plugins on the same midi track. That is, say one particular midi track is first synthesized with plugin x, and then the next region of the same track is synthesized with plugin y, etc. After working with the qtractor and searching the web, I am pretty sure that qtractor cannot do this. And so now, I have begun working with Ardour. Is Ardour capable of using different plugins for different regions of the same midi-track? I realize I can copy portions of an original midi-track to another track and thus, achieve the same effect, but for organizational reasons, I think I would prefer to not do this as my project may expand to more midi tracks than I could personally keep track of. Or is switching plugins on the same midi track something people generally do not do, and if you feel you need a different timbre at a particular place, is the preferred method just to create a new track? Thank you for listening to my perhaps naive questions.

[ANN] Vee One Suite 0.6.3 - A sixth beta release

by Rui Nuno Capela

[UPDATE] As a micro dot release override, the current sixth beta release is out and crunching the earlier fifth to oblivion ;) Howdy, The 'Vee One Suite' of 'old-school' software instruments, aka. the 'gang of three' have bumped over another tiny notch: synthv1 [1], as one polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as one drum-kit sampler, are now being released to the masses. Again ;) There's no big audible changes, if any at all, yet this fifth beta release is rather a probable bug fix drumkv1 LV2 on Ardour. Anyway, it's all gone as follows: - Sample file drag-and-drop support has been added to the note element list widget (drumkv1 [3] only). - Main widget layout changed as much to allow sampler display and element list to expand or grow vertically as needed (samplv1 [2] and drumkv1 [3]). - Sample file path mapping has been fixed for LV2 plugin state restoration, which were preventing Ardour to reload any of the saved session or preset sample files in particular (drumkv1 [3] only). - Custom knob/dial behavior mode options are now introduced: linear and angular (aka. radial) as far to avoid abrupt changes on first mouse click (still the default behavior). - Fixed for some strict tests for Qt4 vs. Qt5 configure builds. We're still available in dual form, as business as usual: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. Enough to tell, the Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later. As always, have (lots of) fun :) **synthv1 - an old-school polyphonic synthesizer [1]** synthv1 0.6.3 (sixth official beta) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Jack ports

by Will Godfrey

I seem to recall someone saying there is a limit to the number of ports jack can handle. What is the limit? For audio, would I be right in thinking L & R as far as jack is concerned are simply added to the total? What about MIDI, how many MIDI ports can jack handle? -- 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 Version Question: 2 versus 3?

by Ivan K

I have some question regarding versions of Ardour that people are using. Currently, I am running Fedora 20, and their software repository has two versions of Ardour available: ardour-2.8.16-12.fc20 ardour-3.5.403-1.fc20 I seem to recall that in the past, despite Ardour3 being available, some people were still preferring to use Ardour2. This seems to be supported by the fact that Fedora offers both versions. Why might one prefer Ardour2 over Ardour3? Thanks

By the way, it makes a long time we plan to do that, but each time we're working on stage on this setup, we finally spent hours on other things (like music and show!!! ;) ), and finally don't do that. But we surely should, and once again I'm going to say that's we're going to try. OK let's say this time we'll find the time! > > Thanks for sharing.
