Finally got around finishing a new track. And it’s just 65BPM so no four to the floor this time. I posted the demo a while ago, this is more or less a definitive version (definitive is a fluid term in my dictionary).

This song is about one of the most beautiful places I know on this
planet, Cala Del Aceite in the most southern part of Spain:

http://www.conilplaya.com/fotos/playasd … eConil.htm

Tools used:

Qtractor for recording and mixing
seq24 for sequencing
The necessary plugins:
- drumkv1 to hold the drum samples (drum samples are all from
- http://samples.kb6.de/)
- a lot of plugins that are part of Distrho or Carla: Noize Maker, Tal
- Reverb III, ZynAddSubFX-LV2, Nekobi
- MDA subsynth
- FluidSynth DSSI for the Rhodes
- linuxDSP plugins (EQ500, DYN500, MBC2B on the master bus)
- Calf Vintage Delay
- LADSPA comb filter, Fast Lookahead Limiter
- GxZitaReverb

The background vocals for the choruses are sung by my wife. The ocean
sample is from Freesound:

Cádiz is pretty close to Conil, hence the choice.

Thanks to everyone for making this possible. Especially falkTX and rncbc, couldn’t have done this without your valuable work.

Making promises that I can’t keep
It’s pushing me, pushing me into a deep
State of sadness, state of doubt
A state of awareness I can’t live without

Making mistakes, so hard to bear
It’s driving me, driving me to a point where
I can’t escape, I can’t shy away
From the daemons I refuse to obey

All is forgiven, all is well…

Awaiting the day that I’ll be relieved
From this burden, this burden that has grieved
So many loved ones, so many friends
All the people on which I depend

Stand up, act now, it’s time for a change
Lingering won’t help, help to rearrange
The current imbalance, the current state
Of things so rush now don’t hesitate

All is forgiven, all is well…

Wolfson Audio Card for Raspberry Pi

Just ordered a Wolfson Audio Card for Raspberry Pi via RaspberryStore. I asked them about this audio interface at their stand during the NLLGG meeting where I did a presentation about doing real-time audio with the RPi and they told me they would ship it as soon as it would become available. They kept their word so I’m hoping to mount this buddy on my RPi this very week. Hopefully it will be an improvement and allow me to achieve low latencies with a more stable RPi so that I can use it in more critical environments (think live on stage). It has a mic in so I can probably set up the RPi with the Wolfson card quite easily as a guitar pedal. Just a pot after the line output, stick it in a Hammond case, put guitarix on it and rock on.

Raspberry Jam Review

Last Thursday the first Dutch Raspberry Jam took place at the Ordina HQ in Nieuwegein. I offered to do a presentation slash demonstration about realtime audio and the the Raspberry Pi so I promised myself to be there at least an hour before the scheduled starting time of my demo. That way I could also join Gert van Loo‘s presentation. When I arrived at 19:15 there was no Gert van Loo though so that should’ve triggered some alarms. Also I didn’t look out for members of the organization as soon as I came in. Instead I chose to dot the i’s and cross the t’s with regards to my demo.

Wrong decision.

About half an hour later the event was closed.

WTF?

I approached the person who closed the event and introduced myself. He replied that they thought I wasn’t coming anymore. Apparently they misinterpreted my e-mail I sent earlier that day that I didn’t manage to produce something workable for the laser show guy. They took it for a cancellation. But immediately the event got kind of reopened and I set up my stuff. We had some audio issues but in the end everything went quite well actually. I showed off what is possible with a Raspberry Pi and realtime audio with the use of some of my favorite software. Guitarix featured of course. I grabbed my guitar, fired up guitarix on the RPi and played some stuff. Hooked up my MIDI foot controller and showed how to select different presets. I also demonstrated the use of the RPi as a piano with the help of LinuxSampler and the awesome Salamander Grand Piano samplepack and did some drumming by using drumkv1. Before the realtime audio demo I presented an overview of the Linux audio ecosystem and talked about the alternatives of how to get sound in and out of your Raspberry Pi. These alternatives are not bound to the onboard sound and USB, since recently it is also possible to hook up an external audio codec to the I2S bus of the Raspberry Pi. I got one in myself this week, a MikroElektronika Audio Codec PROTO board based on the WM8731 codec, so more on that soon. It’d be awesome if I can get that codec to work reliably at lower latencies.

So it all turned out well, I had a great time doing my presentation and judging by the interest shown by some attendants who came up to me after the presentation I hope I got some more people enthusiastic about doing realtime audio with the Raspberry Pi and Linux. So thanks Ordina for offering this opportunity and thanks everyone who stuck around!

More ARM goodies

Bought another Android TV stick based on the RK3066 SoC, the MK808 which is as far as I’ve understood kind of the default board to hack on.

Also bought a BeagleBone Black development board. Why? Because apparently JACK runs well on it, also with USB interfaces (no need for the ALSA softmode option!) so I assume the USB implementation is better than those of the Raspberry Pi and the RK3066 based board I currently own. And I could get it cheaper over here in The Netherlands than other viable alternatives like the pcDuino or Cubieboard, also because of a coupon code I found on tweakers.net so I got a price reduction of a few Euros. Another reason why I bought it are the so-called capes that are available for this board. These capes are basically add-on boards and the cape that has my most attention is the audio cape. I’m thinking about buying that specific cape, solder two Neutriks on the audio in and out and turn it into the easiest DIY guitar effect box ever. Of course with guitarix loaded on it, the devs have done an incredible amount of work recently to get guitarix running flawlessly and painlessly on ARM dev boards like the BeagleBone Black.

Raspberry Pi als virtuele gitaarversterker

M’n Raspberry Pi in actie als virtuele gitaarversterker. Er draait Raspbian op met een gepatchte versie van Jack1 en de laatste versie van guitarix. Als geluidskaart gebruik ik m’n good old Edirol UA-25. Systeemlatency is 256/48000×3 = 16ms. Ik kan nog wat lager (8ms) maar dan trekt de RPi de preset die ik in dit videootje gebruik niet meer.

De gepatchte versie van Jack1 en de laatste versie van guitarix kun je in mijn RPi audio repository vinden. Staan ook nog wat andere pakketjes in die of nog niet beschikbaar zijn in de standaard repositories van Raspbian of die wat meer up to date zijn dan de Raspbian pakketten. Hoe je die repository kunt toevoegen kun je terugvinden in mijn Wiki artikel Raspberry Pi and real-time, low-latency audio op linuxaudio.org.

Ben erachter gekomen dat ik niet de enige ben die hier mee bezig is, er is zelfs iemand die er een complete site aan het wijden is: Amp Brownie – Building a Raspberry Pi Guitar Rig

Nog meer LV2!

Het Portal MOD project is bezig een aantal LADSPA plug-ins om te zetten naar LV2, waaronder CAPS, TAP, SooperLooper en guitarix. En voor zo ver ik begrepen heb werken ze ook aan een van rakarrack afgeleide LV2 plug-in.

CAPS is al omgezet naar LV2 en heb source pakket klaar om up te loaden naar de KXStudio-Team plugins repository. Maar wacht nog even de puntjes op de i af.

Ondertussen is een van de main devs van guitarix ook met LV2 aan het experimenteren. Hij zit alleen nog te dubben of hij heel guitarix in één plug-in gaat stoppen of dat hij alle losse componenten van guitarix om gaat zetten naar LV2.

Voeg daar nog aan toe dat degene achter LV2, David Robillard (aka drobilla), er aan zit te denken om een boek te schrijven over LV2 en je begrijpt wel dat LV2 op het moment best wel een hot item is. Gaat het ooit gebeuren dat er een open source, cross-platform plug-in framework VST naar de kroon gaat steken? De LAD community is er klaar voor, de wrapper tools staan in de steigers (DISTRHO) en met NASPRO is het al mogelijk om eigenlijk alles als LV2 te draaien.

Horus demo

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!

Vakantie

We waren twee weekjes op vakantie. En dan kom je terug en zie je dat er allerlei coole dingen zijn gebeurd:

In de laatste editie van Linux Format staat een zeer prositieve review van Qtractor 0.5.5
setBfree is gereleased, een op Beatrix gebaseerde Hammond kloon, maar dan met een GPL licentie
Guitarix is ook weer een versie verder, 0.23.3. Gebruik guitarix de laatste tijd veel. Fijn stukkie zachte waar.
Rui heeft z’n proto-toys geüpdate naar versie 0.0.8. Zijn al erg bruikbare LV2 plug-ins!

Later meer over dit alles in aparte blog entries.
