Oktalyzer had a maximum of 8. If I recall correctly it downscaled sounds on the fly to 7 bits to gain a maximum of four more tracks. Its samples were noticeably worse in quality and less loud, but back in the day I still had a lot of fun using it.

I think I get the idea - I remember those trackers for Atari ST that also used some similar tricks to play multitrack audio even though the ST didn't have native multitrack PCM playback[1]. I remember that the sound was worse than ProTracker but still "serviceable" if you get what I mean.
But at the end of the day many ST owners would just use it as a sequencer of external gear (thanks to built-in midi ports and SW like Cubase) - those were actually rich people, they didn't need trackers LOL - my uncle had a Roland sound module and an Akai sampler hooked to the ST! I was just a kid and didn't have money for external gear but I was proud of what my Amiga could do for a fraction of the price.
