wip song using lmms, timemachine and a korg r3

by Bruno Gola

Hi there, I started working on this song yesterday using LMMS, some ladspa effects for the drums and a korg synth. It's electronic, inspired mostly by Moderat/Apparat and also kraftwerk. I'm working on some lyrics and more synth maybe. http://soundcloud.com/brunogola/wip I would love any feedback about the directions I'm taking. Also, does LMMS kinda suck on playing samples? I recorded the synth lines using timemachine and imported into a sample track but lmms can't play the samples at any position, only from the start of the sample. Am I doing anything wrong?

xruns no matter what

by Sebastian Rose

Hello, I'm quite a bit puzzled and so I'm hoping to find something I haven't considered yet. I'm using a FireWire Saffire LE Audio Interface, connected to the following PCI card: NEC Corporation uPD72873 [Firewarden] IEEE1394a OHCI 1.1 Link/2-port PHY Controller (rev 01). Software information: ffado built from svn, jack 1.9.8, kernel 3.5.3 PREEMT (no realtime patch) or 3.4.9-rt17 (with realtime patch), libraw 2.1.0. No matter what I configure jack to run with, I get regular xruns every few seconds whilst doing nothing. The last settings I tried were: Frames/Period: 4096 Sample Rate: 96000 Periods/Buffer: 3 (Latency: 128ms) And still no avail, results are like this, just after starting, without actually doing anything: 19:02:48.093 XRUN callback (1). 19:03:03.002 XRUN callback (2). 19:03:05.713 XRUN callback (3). 19:03:08.257 XRUN callback (4). 19:03:12.160 XRUN callback (5). Interrupt information: 21: 0 1 1 33 1087 339542 IO-APIC-fasteoi firewire_ohci Things I tried: Basically everything suggested by the realTimeConfigQuickScan tool, like changing CPU governor to "performance" or decreasing swappiness. I am member of the "audio" groups, which has the following permissions, as per limits.conf: @audio - rtprio 99 @audio - memlock 8388608 @audio - nice -5 /dev/rtc and /dev/hpet are both read- and writeable by group "audio". # /etc/init.d/rtirq status PID CLS RTPRIO NI PRI %CPU STAT COMMAND 1075 FF 90 - 130 0.0 S irq/8-rtc0 1407 FF 85 - 125 0.4 S irq/21-firewire 1063 FF 80 - 120 0.0 S irq/1-i8042 [...] Any advice on what I could be missing? The same system was working some time ago, so I really don't know what I did wrong this time.

First impressions of MusE 2.0

by Dan MacDonald

I've just posted my first impressions of MusE 2.0 here: http://linuxmusicians.com/viewtopic.php?f=1&t=10012 I thought most everyone on this list would be interested and not everyone reads or knows about that forum so.. First impressions of MusE 2.0 MusE, dating back to '99, is one of the most mature MIDI sequencers available for Linux. After over a decades development we have seen it evolve into a fully featured DAW and the project finally made its big 2.0 release at the end of June although you're unlikely to have heard anything about it unless you monitor the Linux audio scene closely. This is a shame as with version 2 MusE deserves a lot more attention than it seems to be getting so I'm hoping to rectify that slightly by explaining why I think this is the dark horse of FLOSS DAWs and one of the most promising Linux audio projects going. I'm a subscriber of the Linux Audio mailing lists so I heard about MusE 2.0 as soon as it was released and I promised the project member who made the announcement, Robert Jonsson, I'd be taking a look soon. Sadly it took over 2 months before my curiosity got the better of me and I regretted waiting so long after trying it. Muse 2's feature set sounded good and it looked promising in the screenshots but there were two main reasons I didn't hurry to try the new release. The first and main reason was that I had tried previous 1.x releases of MusE and I had been underwhelmed. I wasn't a fan of Rosegarden's QT 3 era UI but Muse 1 made RG look nice. Rosegarden is also partly to blame for me taking my time in trying the new MusE. Rosegarden, the other long-standing Linux/Qt FLOSS sequencer, predates MusE and as I've just mentioned I'm not so keen on its GUI which is way too cluttered for my liking so when they made the transition from QT3 to QT4 a few years ago I had my fingers crossed it would bring with it a redesigned and more slender UI but it was not to be. Thankfully MusE's transition from QT3 to QT4 was much more fruitful as I now feel comfortable with the MusE GUI which strikes a good balance between having no icons on screen and the full-on icon overload of Rosegarden. If you can live with its interface Rosegarden is a powerful and full-featured sequencer with most of the features familiar to users of commercial sequencers and in this respect MusE fares just as well if not better as it does so without the clutter. I really appreciate that Muse lets you draw lines within its MIDI controller lanes to quickly define fades as this is a feature I have long wanted in qtractor and is also missing from Rosegarden. qtractor lets you draw MIDI automation curves but these are treated separately from any MIDI controller data you record. You can draw 'freehand' on qtractor MIDI controller tracks and it has a resize tool for MIDI events that lets you select a range of controllers then enter its start and end values but this isn't as intuitive or as easy as being able to draw straight lines to define controllers like in MusE. In this respect its only equal in Linux land right now is Ardour 3. My Linux sequencer of choice at the moment is qtractor but I was keen to see the state of MusE because, as I highlighted in my recent qtractor review on KVR, qtractor lacks a couple of features I feel a bit lost without. The worst of these for me is qtractors lack of support for 'tempo ramps' as Rosegarden calls them or 'crescendos' as they're referred to in MusE-speak. A3 also currently lacks the ability to set gradual changes in tempo and this is a shame as they're quite common. My other big irk with the current state of Rui's DAW is the inability to copy automation but there is no such problem under MusE or A3. One of the new features in MusE 2 is a score editor, something entirely absent from Ardour and qtractor although personally I'm not concerned with having a score editor integrated into my DAW as I rarely notate music. MusE's current support for musical score appears basic and doesn't compare with Rosegarden's integrated score support. FLOSS score creation is being handled very well by MusE's sister project so I'm not sure why they bother to be honest as I can't see it catching up to musescore unless the two merge. Enough about MIDI, what about audio? Reading the Ardour forums and having spent much time in its irc channel, I know that one of the most frequent feature requests is integrated wave editing and I'm sure Rui has had more than a few requests for such a feature in qtractor too so I'd say one of the biggest selling points of MusE is that it would seem to be the only Linux DAW to offer integrated audio editing. The editor is basic but it has the most commonly used audio editing features so chances are you won't have to use an external editor much, which is something else MusE supports, should the internal editor not cut it. At this point I'll mention that the only real bug I seem to have found in MusE so far is the audio editor doesn't work for me under 64 bit Deb Wheezy although it works fine under 32 bit Wheezy and Robert says it works for him under 64 bit Kubuntu too. I had trouble working out how to record audio into Muse at first as it wasn't documented at the time but the docs have been updated to cover this since I raised it as an issue. Just looking at this process, compared to Ardour and qtractor Muse is the least user friendly when trying to set up a track to record but once you know how its done its not a prob and this was the only aspect of the program that had me scratching my head. Otherwise I think MusE is the most user friendly Linux DAW and I didn't have to inquire about or refer to the manual for anything else. I was also disappointed that MusE 2.0 doesn't currently support the creation of mono audio tracks although you can change stereo to mono tracks and creating mono tracks is to be added soon. MusE allows the easy drawing of automation curves for gain, pan and LADSPA FX and apart from the two slight probs I've mentioned, it looks like I should enjoy working with MusE for audio as well as MIDI. Observant readers will have noticed that despite my praise for this new MusE I said "My Linux sequencer of choice at the moment is qtractor" because it supports native VST and LV2 plugins, it is more stable and lightweight than A3 and it will likely remain my choice until the big MusE showstopper gets resolved - plugin support. Like Rosegarden, MusE currently only supports LADSPA and DSSI plugins which is fine IF you don't use MIDI, you only use external MIDI sound modules OR you are happy with MusE's integrated synths / the very few DSSI plugins available / LASH sessions. You could use Windows VST plugins via DSSI-VST with it but that isn't an option I'm interested in nor would anyone else who is concerned about plugin performance and stability care much for DSSI-VST. Although native VST and LV2 support is planned, no-one is working on it yet which is a great shame as without such support this very promising DAW isn't usable for me yet. When MusE does gain such functionality I think there's a very real chance it will become my DAW of choice and I highly recommend others give it a go especially if you're looking for a Linux sequencer for MIDI hardware.

SuperCollider 3.6 alpha

by James Harkins

SuperCollider 3.6 alpha is coming out today, with a demo at ICMC and launch party in the evening. http://www.kiberpipa.org/sl/event/unleash-collide-supercollider-ide-preview… The big deal with sc3.6 is a new cross-platform editing environment. I've been doing pre-release testing and gotta say, it's pretty swank. My intent was to do some testing once in awhile and use emacs for most of my coding, but it didn't take too long to switch over to the new editor for everything. And this is coming from an emacs evangelist... It's qt based (like Frescobaldi 2 for lilypond) so it's good in Linux, OSX and Windows 7 (eventually XP too but there's a weird issue that hasn't been fixed yet). I'm using it in Ubuntu 12, clean and smooth. It's alpha but even now, it's hard to crash, so don't be scared of its alpha status. I expect binaries will be uploaded to http://supercollider.sourceforge.net. I doubt that an alpha will go into Linux package repositories, but sc builds easily in Linux (cmake). Enjoy :) hjh
