As of 2013-09-30 I will be unemployed. Can’t tell any details here but I’m already very busy looking for new job opportunities, applying for jobs and doing job interviews. If all goes well I can start right away at a new employer. I even had to take my CV offline because I risked getting too many offers.
I’ve also accepted an offer to do some Linux audio consultancy work. Just received my contract and I’m stoked about it. And no, can’t share any details on that either. When it comes to details this is a lousy blogpost, leaving you a bit in the dark, sorry about that. But as soon as I can tell more I’ll do so. For the moment I think it’s ok to say that I’ll be doing consultancy work for a project to create an instrument based on an ARM device. It’s a bit of a dream come true, doing paid Linux audio R&D. So back to work, I also have to set up a website for my consultancy activities. And get everything ready for the first workshop at De Bakkerij.
Starting September 7th I’m going to conduct a series of 6 workshops on music production with open source software at De Bakkerij in Castricum. With software I also mean the operating system so the OS I’m going to use will be an open source based one (probably Ubuntu or Debian). So basically it’s a series of workshops on music production with Linux Audio.
Last week I had something like, what the heck, I’m just going to mail De Bakkerij to ask if they’re interested since they host more DIY initiatives like the workshops inititiative I proposed. I didn’t expect much of it but I immediately got an enthusiastic e-mail back from the promotor of De Bakkerij. So after a few mails back and forth it was a done deal.
Rough outline of the workshops:
Introduction and base principles of open source software and using it for music production. What is open source, why use it, how does the open source audio ecosystem look like and will my hardware work?
Recording with open source software. What software is available (DAW), how to use it during the recording process, base principles of recording instruments and vocals (I’ll be focusing on home recording and not recording complete bands).
Making music with open source software. Softsynths, samplers, drum machines, amp/cabinet modeling, sequencers, trackers, DAWs, MIDI/OSC, plugin frameworks etc.
Mixing and mastering with open source software. What software is available, what kind of hardware do I need, base principles of mixing and mastering.
Showcasing the possibilities of the usage of open source software with the focus on low-cost solutions like the Raspberry Pi and RockChip based devices.
Concluding workshop: listen to and discuss the musical projects made by the attendees, discussion on music production with open source software.
There’s no fee for attending the workshops but you do need a notebook or netbook and an empty USB memory stick of at least 4GB.
Somehow I managed to arrive just in time to set everything up for my workshop, like always. I’m very good at stumbling in at the very last moment. The Nvidia binary blob didn’t like a beamer attached to it so I couldn’t properly display my slides. The well-filled room didn’t seem to care, they were more interested in what I had to say and the equipment I brought with me. I talked and talked and only briefly demonstrated the Raspberry Pi I brought with me. Guess I could’ve done a whole workshop about the RPi because apparently that little device caught most of the attention.
Right after my workshop I rushed to Rui’s intercalated workshop about the software he develops. I missed his first workshop which took place on Thursday. But since Rui had so much more to show after that initial workshop the LAC2013 organization decided to allot him more time for an extra workshop. But I also didn’t want to miss Jörn’s workshop so I decided I also wanted to see part of that workshop too. Even though I’ve been using Rui’s software for years (I’m a QA, Qtractor Afficionado) he showed things I had never seen before. And I probably attended one of the best parts of Jörn’s workshop where he showed and made us listen to what he did with a live recording. An ear opener, really, amazing what you can do with a good pair of ears, years of experience and the right tools.
Then it was lunchtime already. Missed out on the warm lunch but when that was all cleared the alternative food stand was set up again which had probably even better food. They had great salads, fruit juice, bread and other tasty things, all for free. Many, many thanks to the organization for setting this up, it really added up to the overall positive vibe of the conference.
Now I had a bit of a problem. I needed to go to the Forum Stadtpark to do a sound check for the Linux Sound Night. But walking was not an option with all my stuff and public transport would take too long as there was no direct connection. Luckily I could tag along with the guys from SuperDirt² so I hopped into their car and off we went. SuperDirt² had to play last so they did their sound check first. I watched their sound check in awe, these guys were good! I was up next. Everything went smooth, monitors were good, the sound guy was a really cool guy and so was the stage manager for the event. All omens were very positive!
We got back right on time for Albert Graef’s talk on creating LV2 plugins with Faust. We witnessed a glimpse of the future. If I got it right it will be extremely easy to create your own LV2 plugins in the near future. Just throw some Faust code against it and upload it with your browser and within moments you can download your own LV2 plugin! Time to learn some Faust I guess. One lightning talk later we witnessed another glimpse of the future. No, not my acrylic guitar in the hands of Bruno Gola but the world premiere of the MOD Quadra digital pedal board. The excitement was tangible. But the MOD guys quite easily redeemed the high expectations. The MOD Quadra is simply an amazing device, the web GUI looks stunning and it’s all so easy. And it runs on Linux people, using the LV2 framework. If this doesn’t propel LV2 into mass adoption then what?
For dinner we ended up in a nice Italian restaurant. The Gösser tasted good, same for the dish I ordered (Calamari alla griglia). After dinner we walked to the Forum Stadtpark where we were welcomed by the pleasant chaos of Android drummers. I installed the app and joined the concert. It was fun. Then the beamer got switched on showing us two terminal windows with vim on the right side and something compile-ish on the left. On stage a person in front of a notebook, coding live. The result? Really cool stuff if you ask me, just watch for yourself.
Algorave to the max all y’all!
Then it was time for something remotely dance related, namely me. Really enjoyed the gig even though my voice let me down after the third song. The guy that came after me unfortunately was a bit the odd one out so the contrast with the last act, SuperDirt², couldn’t have been bigger. As soon as Käpt’n Dirt hit the strings of his cello we knew this was going to be a blast. And when Ras Tilo kicked in the party was complete. What a great show!
After the encore of SuperDirt² it was time for the Open Jack Session. Not Jack as in JACK but Jack as in 3.5″ mini-jack. It was lying there on the table on stage and after ClaudiusMaximus Marije Baalman plugged in. Live coding in SuperCollider with every once in a while Marije stretching her arms because of the anti-RSI alarms that kept popping up. Great stuff, very enjoyable to listen to and the added humorous note of the anti-RSI alarms perfectly summed up what this conference was all about: having a great time. Despite the submerging inebriation I was enthralled.
We stayed until we got kicked out. That’s how it should be. Sole minor blemish: the beer. That Murauer stuff was close to undrinkable.
“Hello, I’d like to know if I can take my electric guitar with me as hand luggage, would that be possible?” “Well that depends on the whims of the cabin crew.” “So if I can’t take it with me in the cabin would that cost me extra?” “Yes, that will be €200.”
So I decided to take my guitar apart, wrap it in a big towel and put in my suitcase so that I could take it with me as standard baggage. I didn’t want to run the risk of having to pay €200 extra. When I arrived at the airport I was sitting next to a young lady with, yes you guessed it right, a guitar as hand luggage. She didn’t have to pay anything extra. Grmbl. You’ll see that when I unpack my stuff in Graz the neck of the guitar will be broken or something. Let’s hope not.
I had a transfer in Munich which went smoothly. The whole journey went smoothly actually. Thanks to 3G internet, QR codes of my tickets sent to my mobile phone and Google maps. Especially those QR codes are very practical, they save time and paper. Every counter and gate has QR scanners and the personnel just puts your mobile phone in the scanner and you’re done. Maximum efficiency. Google maps helped me out on quite some occasions too although the Grazians were very helpful too.
So on Friday around 2 PM I walked into the main conference building. I couldn’t be there on Thursday because of my son‘s birthday. So I already missed quite some interesting workshops, presentations and lightning talks. I was kind of bummed about that at first but as soon as I entered the building I forgot about all that. It was still lunch time and everyone got together in the main building to eat something. It was a warm welcome and great to see all those people again. I immediately spotted the MOD guys (my goal for this LAC was to get a MOD endorsement) and got acquainted with the one and only Kirill Alferov which was quite a nice surpise. After having something to eat I decided to check on the status of my guitar and to put it back together again. Luckily the guitar had survived the journey unharmed.
As soon as I started screwing the neck back on the MOD guys approached me to ask if they could borrow my guitar for their lightning talk on Saturday. Sure, but only if I could play around a bit with the MOD Quadra they brought with them. This was no problem so a few minutes later I found myself happily noodling and tapping footswitches on this amazing device. Even though it still had some rough edges it all felt, looked and sounded very professional to me. Yes, the MOD is a fine example of my view on Linux audio development: world domination. And I mean it. Within 10 years Windows and Mac OS will only exist for tablets or other small portable devices with touchscreens and Linux will be the only viable alternative on both other ends of the scale: embedded devices and fully fledged audio workstations in professional studios.
Right after that I headed off with Marc Groenewegen to the Linux/Ardour in a Recording Studio workshop where I soon found myself going through the mixing console manual together with Frank Neumann to find any references to GPL clauses as the console was running on Linux (see how quickly world domination is approaching already?). Of course we found nothing. The workshop was a bit too specialized for me so I decided to check in at the hotel and get rid of my baggage. The plan was to eat Schnitzels for dinner but when it was time to go to the restaurant it was pouring so we (me, Funs & girlfriend) arrived at the restaurant completely soaked. But I couldn’t care less when I got served my Schnitzel XL with a big pint of Puntigamer.
After dinner we went to the Mumuth. Amazing building. But me and electroacoustic music don’t go together that well. It’s not that I don’t like it. I’ve seen Sachiko M once and she blew me away with just a sine wave out of a sampler. Not just with the sine wave but more with her performance, her being there and getting totally absorbed by the sounds she was making. They had to carry her off the stage after she was done. Well, that didn’t happen at the Mumuth. Or I should’ve stayed until the end because now I’m basing my judgement on a mere three perfomances because I left earlier as I didn’t really dig the vibe.
I’m planning on writing a nice and lengthy epistle on LAC2013 but for now you’ll have to do with some videos captured by rncbc and alg0rhythm. Thanks for uploading the vids!

Using your electric guitar with Linux – workshop excerpt
During LAC2013 it became clear to me that I have quite some non-Dutch blog readers. So I made up the balance and decided to switch to English as the main language for this blog. Other factors that got me around:
Blogging in English will hopefully improve my proficiency of the Englsih language
There are more people doing Linux audio that master English than those that master Dutch
Apparently I write articles sometimes that deserve some broader attention
The main language within the Linux audio community is also English
So there we are, I’m going to start writing English blog posts from now on. The blog itself will go into a transitional phase now, I have to translate some captions and I need to rethink the whole category and tags part of the blog.
Twee mailtjes in mijn inbox vanochtend. Allebei mijn submissions voor LAC2013 zijn geaccepteerd! Dus op LAC2013 ga ik een workshop doen over je electrische gitaar gebruiken met Linux audio tools en ik ga een optreden doen op de Linux Sound Night.
Ben blij dat m’n submissions zijn geaccepteerd, heb alles al geboekt en zou zonde zijn als ik niks had kunnen doen. Die kans was er want kennelijk waren er best veel aanmeldingen.
Submission #34: Using your electric guitar with Linux
Almost 20 years of experience with playing guitar and over 10 years of Linux experience, one day that just had to come together. With the advent of guitarix, a virtual guitar amplifier for Linux, this became reality and coupled with the modularity of the Linux audio ecosystem a whole plethora of possibilities became accessible. In this workshop I will show the current possibilities for a guitarist with Linux audio in a hands-on, live setting.
Submission #35: The Infinite Repeat
A musician with over 20 years of experience and a computer with Linux. That’s what it boils down to. The result: conventional, decent song-writing, different sounding because of the choice to not walk the threaded paths and because of an autodidactic background, an outspoken personal taste and a open-minded worldview.
Een alleszeggende titel. Vorige week kennis gemaakt met iemand die bij mij om de hoek woont (en dan ook echt om de hoek) die een complete educatieve muziekomgeving onder Linux heeft gebouwd met behulp van JACK, mididings, QMidiRoute, QmidiNet, Qsynth en Bash scripts. Waanzinnig. En werken als een trein. Hele klassen kunnen via het netwerk met elkaar muziek maken, meespelen met backing tracks of gewoon lekker rommelen met diverse instrumenten. Heel bijzonder en je begrijpt wel dat ik heel graag wil meewerken aan het verder perfectioneren en professionaliseren van deze leeromgeving.
M’n Raspberry Pi’s lagen wat stof te happen maar daar is sinds een paar weken wel een einde aan gekomen. Werd eigenlijk getriggered door een post op de Jack-Devel mailinglist met een patch voor ARM platformpjes zoals de RPi. Een vergelijkbare patch was maanden geleden al een keer gepost maar is bijkans niet meer googlebaar dus aan mijn aandacht ontglipt. Door de patch op Jack-Devel kon ik weer verder als in JACK (zowel Jack1 als Jack2) draait prima op de RPi met deze patch. In eerste instantie kreeg ik de boel niet goed draaiende (vooral full-duplex kreeg ik niet voor elkaar) maar na me goed ingelezen te hebben heb ik mijn RPi zo weten te tweaken dat deze bruikbaar is voor real-time, low-latency audio. Afgelopen woensdag m’n bevindingen laten zien en horen op een Horus meeting en de RPi hield zich prima als virtuele gitaarversterker. En dat allemaal op een ontwikkelboardje van nog geen €30,-. Mijn bevindingen heb ik neergepend in de linuxaudio.org Wiki: http://wiki.linuxaudio.org/wiki/raspberrypi
Ook op mijn werk heb ik het erg druk. Heb me gestort op het WebRTC gebeuren en dat begint nu wel te lopen. Klanten zijn bijzonder geïnteresseerd in het videobelplatform dat we aan het ontwikkelen zijn en het werkt gewoon goed. Ook is het altijd fijn om nieuwe dingen te leren (WebRTC, WebSocket, STUN/TURN/ICE) of je meer te kunnen verdiepen in dingen waar je al wel wat van af wist maar die je nooit echt praktisch hebt hoeven toepassen (audio- en videocodecs, encrypten van datastromen, iptables). Ondertussen zijn we al weer verder aan het kijken naar een volgend project waarbij de focus ligt op router-achtige hardware en software, oftewel we gaan proberen zelf eenvoudige network appliances te gaan bouwen. Onze bureaus worden inmiddels bevolkt door RPi’s, MikroTik RouterBoards en PC Engines Alix boardjes. En die mag je dan onder de baas z’n tijd gaan zitten hacken. Hoe vet is dat. Vooral als het werkt en je met elkaar kunt bellen via een boardje met een 400MHz MIPS processor waar zelfgebouwde OpenWRT firmware op draait.
Check ook de andere artikelen getagd met The Linux Setup. Zijn allemaal erg fijn om te lezen en ik vind het ook een erg tof initiatief. Het idee is zo simpel maar het werkt wel heel goed. Ja, er zijn honderden forumdraadjes, blogs en artikelen waarin mensen uitleggen wat voor hard- en software ze gebruiken maar op deze manier is de voorselectie al gemaakt. Bovendien zijn de setups zeer divers en de vragen relevant. Gewoon even doorheen scrollen en lekker lezen die handel.
Na weer een redelijke helletocht (files en heel veel regen) was ondanks mijn late aankomst mijn pizza Sea Passion nog warm. Nou ja, lauw, maar desalniettemenin nog zeer eetbaar, ja smakelijk zelfs. Gelukkig maar dat er pizza was besteld want dat maakte het een stuk makkelijker om het lokaal te vinden waar de Horus bijeenkomst werd gehouden. Je rook het lokaal al van verre.
Spullen uitgestald en na een goeie discussie over Flash, closed source vs opensource en de toekomst van Linux audio heb ik wat laten horen en zien wat je zoal kan met een Linux machine en de nodige audio applicaties. Had ook een gitaartje meegenomen dus begon mijn presentatie met één van mijn favoriete Linux applicaties, guitarix. Daarna was het de beurt aan Qtractor en seq24 en als klap op de vuurpijl werkte het project waar iedereen toch wel nieuwsgierig naar was (mijn KVR contest inzending van een tijdje terug) uiteraard voor geen meter. Linux audio op z’n best. Het blijft een strijd.
Bedankt Marc voor de geslaagde en gezellige avond!
