Hi!
I had to realize in many cases, that the Renoise Amiga Mod compatibility is not very good.
For Instance…
Space debris.mod
joyride.mod
serial killer.mod
serial-killer(eps2).mod
and much other…
2 questions to this.
Why is the Amiga Mod Playback compatibility from Renoise so bad.
Are there plans to fix/improve this in the future, or are this abadoned functions?

Here’s the cold hard truth… We’re living in 2022, not the 90’s… And Renoise is attempting to provide a modern “DAW” solution with some oldschool tracker vibes.
Renoise has never pretended to be, nor advertised itself as, a 100% accurate oldskool MOD player engine – So please forget that notion, because it will never happen…
Renoise provides you with the “pretty good” ability to import some classic old tracker MOD formats, purely as a convenience to help you bring your old stuff into a modern environment – that’s it! – Import your oldstuff and then build on top of it.
If you really require 100% MOD playback accuracy, then you should simply use an Amiga/Atari emulator, or DosBox, or whatever it takes to run the original software – whether it be NoiseTracker, SoundTracker, OctaMed, FastTracker, ImpulseTracker, ScreamTracker, or whatever…
Renoise will never, ever be the 100% perfect MOD playback engine that you desire – END OF STORY.
When it comes to playing back old MODs, you might have better luck with MilkyTracker, or ModPlug Tracker, or (my personal favourite) XMplay.
I love the MODs you mentioned – Space Debris in particular, which I grew up with as a kid – but Renoise is trying to look forwards, not backwards…
ok thx for clearness on this point.
