Oktalyzer
Oktalyzer is a commercial tracker for the Amiga computer by the German developer Armin Sander and distributed by Mayer Verlag in 1988. The latest version (1.57) was published in 1991.
Oktalyzer is able to do software mixing of audio channels. For each of the four audio channels available on the Amiga, you can choose to have normal playback or two downmixed virtual channels, at the expense of reduced audio quality. This way it is possible to play up to eight channels in total, but the decreased audio quality and required processing power makes software mixing unusable for situations where CPU consumption was an issue, such as games and demos.
Oktalyzer has a bigger and more intuitive user interface than most trackers at that time, but it also sufferes from severe limitations like the inability to address add-on soundcards or utilize any extra processing power of faster CPUs. Also, Oktalyzer does not work on modern add-on graphics boards.
