I decided to take a break from my more serious musical projects (and my studies) and write a piece based around the very first duet I learnt on the piano. I wanted to make something fairly cheesy, but still fun to listen to. It kinda morphs from cheesy chip into cheesy fifties jazz.

Reflections on what’s going on in my life at the moment. I feel as though I’m on the threshold of not only a new chapter, but a whole new book. I’m finishing uni this year and getting married soon after – I can see the landmarks up ahead, and I feel as though I’m on the brink of forever. Whilst everything ahead is positive, there’s always some sadness in losing a lot of what I have at the moment. But part of living is making sacrifices and moving on.

This is my first project using Mobile Processing. It’s essentially a MIDI drum machine, with five preset drums: kick, snare, open/closed hihat, and cowbell. Each row represents a ‘tick’, and when you press play, each tick is played in turn. It has been tested on a Sony Ericsson K800i.
Note that at the moment, you can’t change the tempo, can’t load or save patterns, can’t have more than one pattern, and can’t choose which drums to use. I might include those features in a later release. For the moment, though, it’s a fun way to waste a few minutes.
A musical project.
The first thing you’ll notice is that this is atonal. I did initially work with a fixed key (E minor, in fact), and experimented with a variety of other keys, too; everything from simple triads to pentatonics, seventeen tone equal temperaments, and even a completely random set of frequencies, but overall, I think that a three octave span of twelve tone equal temperament frequencies is the most effective.
The sounds are generated on-the-fly; they are simple sine waves with a decay. Internally, the x-coordinates of the particles are broken into a series of ‘frequency bars’. Particles move along, building up energy, and eventually release this energy as a musical tone; the frequency is determined by the bar they are in. The frequencies are randomised.
Left clicking will create a ‘beat-particle’ for the frequency bar under the cursor. These particles will emit a tone every 2, 4, or 8 quantisations. Right clicking creates a ‘pulse-particle’, which emits a tone every x quantisations, where x is randomly determined.
Also in the code, but not enabled in the applet, are ‘orbit particles’ – these are the same as normal particles, but they choose a normal particle to follow as quickly as their current energy level will allow them to. They have a 5% chance of changing their target every tick.
If you run the applet, you will probably notice that the audio and the visuals are not perfectly in sync; unfortunately, this is a drawback of the Java sound API in conjunction with all of the maths and rendering going on every drawing cycle (at around 60 frames per second).
