@Stevo:

Hippel7V works fine, really strange!

These are the versions I'm using:

- Delitracker 2.27
- AHI Noteplayer 1.08
- TFMX 7V 1.90
- TFMX Pro 1.98 (altough this shouldn't matter, it's the 7V one I use)
- Hippel 7V 1.00 (tested with the great Amberstar intro song)

I use those genies:

- AHI Noteplayer 1.08
- Decruncher 1.30
- Deli-Wizard 2.20 (whatever this is *g*)
- ModuleInfo 1.70

I will try the TFMX replayer from Aminet, thanks for the hint!
