Finite State Machine Sequencer

For the last years, I have been working with a drum trigger interaction system based on an acoustic drumset and the Nord Modular G2 synthesizer. The basic idea is to control multiple step sequencers by drum hits. Like that, the musician can interact with preprogrammed note patterns in his own musical feel and timing. People keep asking me how they could reproduce this approach on their own computers and beyond that, the G2 system is somewhat limiting for such a task, especially when the compositions get more complex.

Some weeks ago I discovered the call for works for the CTM.13 MusikMakers Hacklab and proposed my idea for an interactive graph-based step sequencer. The proposal was accepted and I spent the week on CTM Festival building the prototype as a Java External for Max/MSP. The Hacklab was a very inspirational gathering of music, art and visual developers collaborating within their projects and sharing ideas and concepts. For example, Imogen Heap was working with her team on their exciting musical gloves project. I set up an electronic drum kit and my stage LED Light modules as an interface testing environment. In many conversations with other artists in the lab I developed a basic concept for the interaction between the drum kit and my sequencer prototype.

Basically, the graphical sequencer consists of a finite state machine that can be played by a musician. It is a Max object that accepts any signal (e.g. MIDI) as input and sends predefined signals to the outputs. In the graphical representation, the nodes represent musical events or any other signal that Max can handle, e.g. MIDI notes, chords, OSC messages or visualization commands. The edges connecting the nodes define the rules for the transition from one node to another over time. Multiple outgoing edges are interpreted as alternate choices, giving the possibility to express a musical composition in form of a Markov Chain.

I added two more things to that concept to create the possibility of interaction with this graphical composition: An emitter is a start node that listens to a specific event, e.g. a drum pad. When activated, it emits a token into the graph that will transition the nodes when it recieves the “step” signal, e.g. from the bass drum trigger. You can now play this graphical composition with a simple drum interface:

So far, that’s it for the prototype. I can’t wait to try out hacking some more complex compositions in the sequencer and include it into my live setup. But of course, there’s lots of work to do until then, and we developed additional ideas for adding conditions to the graph, to express larger musical parts in a simple graphical way. There will be a free download of the basic Max external and/or a standalone Java application later, but this may take some time.

September Tour

Not only that we have landed on Mars again, discovered the Higgs Boson and found out that a flimsy optical cable can speed up Neutrinos. There also has been written an article about my album artwork which features the stylish TJ Evolette A display font:

And I got a lot of nice reviews for the music: Jazz-House-Schule on, Der Einsame Reisende im Weltraum on and even Noisy Neighbours seem to really like the album in their #36 edition.

In September, I will finally start for another short but exciting Germany Tour. If you’re interested in a hands-on explanation of my setup, come to my Remix Lab Session at #a2n_werkstatt during the Berlin Music Week. I will play an experimental setup together with Steve Pfaff on bass and Bernhard Range on Samples.

New Album: Interstellar Getaway

Today is not only Towel Day, but also the release of my third album “Interstellar Getaway”. It’s supposed to be an astronaut’s soundtrack, travelling in his spaceship between the Planets of nearby solar systems.

It was recorded at Tricone Studios located in Funkhaus Berlin and mixed by Guy Sternberg in his analog Low Swing Studio. I’m very proud of the result and the fact that this is my first album to be available on Vinyl LP!

Sebastian Arnold’s new album “Interstellar Getaway” tells the story of a lonesome space voyager. By no coincidence this relates to Seb’s live show, which may actually feel like watching someone playing the drum kit and driving a spaceship at the same time. Still focusing on the beats, his recent sound developed to a more consolidated and song-oriented form, channeling a wide palette of styles from electronica, jazz and post-rock to dubstep. This time, the great escape into the galaxy features interplanetar travelling, bitchy computer games and fast-paced flights through the stratosphere accompanied by thrilling synth basslines, 8-bit sounds and impulsive drumming with a hint of wanderlust.

You can get the CD or LP+Download on the beeah–music Shop page. The Album is also available for download at iTunes, Amazon and Musicload.

See you tonight at the release party!

Spring Concerts and a Free Download

I have been up to a lot of things lately. In the last months I recorded and produced a new album, which will be released on May 25. It will be available as digital download, CD and Vinyl LP. You can listen to one of the new songs right here! This seems to be another drum-controlled computer game where you have to collect strange purple raspberries. Feel free to download and share it.
