ok cool, that helps. so what scales have a suitable mood / feel for techno. major seems too bright, minor a bit sad...are modes the way forward, and if so which ones?

i heard that the whole tone scale gives good results for acid lines. but where i get confused is how to harmonise it - say you made an acid line for the whole tone scale, i dunno but let's say a loop using c, e# & f# - then how would you fit this against a background chord? or do you just have to forget using a chord under it? confused!
