bcr harms 0.1

bcr harms takes a model of the quantum harmonic oscillator and adapts it as a soft synth. A little while ago I came across this pretty cool applet that simulates the coherent states (so called Glauber states) of the quantum harmonic oscillator. You can read more about quantum harmonic oscillators on Wikipedia, or perhaps a quantum physics textbook. bcr harms takes this model and turns it into a soft synth. The interface is again based on the BCR2000s knobs and buttons.

There is an applet version for playing with, but the standalone version will definitely perform better.

Instructions:

Download and run with java -jar bcr-harms.jar.

The top row of knobs lets you set the relative amplitude of the first 8 states of the harmonic oscillator. The first row of buttons will select single states. With the bottom left hand knob you can set the average energy and force a Glauber state. Importantly, the stop/start button is situated on the right hand side, where the BCR2000 store button is. There are a few other parameters to play around with too. Furthermore you can select single states by sending MIDI note on messages to the application, this lets you play it somewhat like an instrument.
