Johan Kotlinski (he of LSDJ fame) wrote a extensive overview of Amiga Music programs for a college course. It ahs now been translated to english and posted on chipflip:
As it was written for a technoculture-course at university, there is a relatively extensive historiography of the early demoscene and how it evolved from cracking. This means that the specific Amiga software part starts only half-way through the text. It starts with describing the brief birth of Amiga-trackers in the commercial sphere: Soundtracker didn’t sell well but was reverse engineered and appropriated in the demoscene. It became the dominant software on Amiga, and set standards still used in contemporary trackers such as Renoise.
