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. There's a video of it in YouTube and the source code is also available.

Megane Rellu

Megane Rellu is an Amiga 500 40 kilobyte intro for the Finnish Amiga Party 2009 40 kilobyte intro competition. It features most of the effects from the Major Release demo, a software synthesizer and a 328 kilobyte song, all in 40 kilobytes. There's a video of it in YouTube and the source code is also available.

Siepura is an "analogue sound modelling" software synthesizer for GNU/Linux. It 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.

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.
