How is it made
Initially I did the music in MIDI format. I used Tinyseq for composing and Winamp for converting MIDI audio to .wav files. Unfortunately I did not have skills to do it for "Öö" and "Mure" and they were made prior to moving to another operating system... so I apologise if they tend to sound worse.
Nowadays I use LMMS with ZynAddSubFX software synthesizer. In this way, I can also play directly on the computer keyboard and "experiment" with sounds. Recently I have also used FluidR3 soundfont by Frank Wen as well as built-in instruments in LMMS.
