Here are a few software projects I've done or been involved in.

Tutka

Screenshot of Tutka Tutka is a tracker style MIDI sequencer for GNU/Linux. I wanted to continue composing the songs I had written using an Amiga program in a modern environment so I decided to write a similar program of my own. Tutka is my main project.

Siepura

If has 24 voice polyphony, 3 oscillators, 2 ring modulators (can be swapped for frequency modulators on oscillator 3), noise generator, 2 LFOs capable of oscillating at audio rates, 3 ADSR envelopes, 24db resonant lowpass filter and a comprehensive modulation matrix with 130 possible routings. It uses the ALSA sequencer API for MIDI input and ALSA for audio output.

Major Release

Screenshot of Major Release Major Release is an Amiga 500 demo for the Assembly 2004 oldschool demo competition. Technically it is the most demanding personal project I've done so far. I tried to push both the old computer and myself as far as I could. The result was satisfying and reached the second place in the competition. The source code is also available.

Hätä

Screenshot of Hätä Hätä is a cross platform demo for the Assembly 2002 demo competition. It is also an example of what I can do on the multimedia front. It uses JRm-core, my portable demo engine. An Amiga 500 version is also available.

Noir
