yes I agree about euclidean waves - but as a starter - I think it's better to get pams and then, if and only if, there is frustration with not being able to change euclidean ratios on the fly , get euclidean waves - Pams forces you a bit more to think about what you are doing, from what I can tell (not having euclidean waves) so may be a better learning tool too - rather than just wiggling away...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
