Thanks chb. I will contact Carsten.

Hi Alex. Thanks. I already found the mentioned text file via way back machine. You can find it now here and the module format here. I also decoded more of it like the mentioned wavetables and found some bugs. For example the order of the effect values is loaded in a slightly different order than documented.

I also found out some additional things like how the song speed really affects tempo and sampling rate etc or how long one note entry is played.

But I can't get my head around the wavetable stuff. For example the first Ambermoon song uses a wave that is only 32 bytes in size. It forms some wave. But the resulting song has a very diverse sound with that little wave while I only hear some short beeps in my reimplantation. I don't know how such a small wave could even produce such interesting sound even with an ASDR envelop or LPF.

I also created a new song with an instrument that only has a 32 byte sine shaped wave. It sound pretty nice in SA but is only a boring beep when playing it on PC. There must be something else which shapes that wave. Maybe some algorithm which dynamically affects the wave.
