Have a look at the general
Tracking board, several threads about samples there.
edit: About the playback issues, the first half is solved: XMPlay defaults to
higher quality mixer settings than those of the original Fasttracker II and MilkyTracker, therefore you need to go to Options and stuff (right-click the main player window or press F9), then go to MOD and set Ramping from
sensitive to
normal. And while there, also change Interpolation from
sinc to
linear. That'll give you the overall same sound in both programs.
The off-tune notes (I take you mean in some of the 0xx arpeggios) are caused by playing the pretty long chip sample loop (189 bytes), basically a low sample, so high it's banging some of the original mixer limits and the tracked
D#5 04 049 for example isn't what you actually get. It sounding about right in MilkyTracker is in fact a playback inaccuracy that will most likely be fixed which in turn will make your notes sound off in Milky as well. So, the module would also need a little fixing but maybe it's not important as it's your first one and you don't want to get stuck in it.
Thanks for unearthing the issue though.
I attached your module rendered from Fasttracker II, the way it technically should sound.
