I think the whole "Minimal" tag is a bit of the wrong word to use Si, id just say "simple" because Minimal is a style which people will get confused by - "minimal acid techno"?? more pigeon-hole-ing..

I think if the percussion was simpler, but not just a 909 / 808 kit, that would be halfway towards the sound your after.

Theres thousends, nay..Millions of drum kits to be used in tracks, so thats an option to consider.

A few loops maybe, but not obvious..

I very much agree with the use of more Eerie de-tuned synths and FX, thats one elements which is missing, that and a nice analogue bass melody :D
