WaveTracker is a free and open source music-making software for Windows. It uses basic wavetable synthesis and sampling to generate sounds, with endless combinations of effects to warp, modify or distort waves and sounds.
It's just a week old and looks super dope. Wavetracker is inspired by Famitracker and pxTone Collage.
Dn-FamiTracker that is also open source[1]
Still I hate the trend when something is done by .NET is mostly only for Windows.
