Esion Xli ST v1.0

About

Esion is another notable early contribution to the Atari demoscene music production pool (Reunanen, 2010). "Esion" (which is "Noise" spelled backward) offered early sampling integration and multi-channel structural playback designed around the ST's precise timing constraints.

Also known as Protracker. It is a 4 channel .mod composer, very much alike Protracker on the Amiga. 50 kHz multiplex replay on 8 MHz STe. Different versions for ST, STe and TT.

A norweigan tracker developed as Esion XLI, and planned to go final as Esion XLII. Well it never happened, and the program changed name to Protracker for version 1.2.
