what exactly do you mean by 'get tonal rhythms out of euclidean circles'?
do you mean melody? - I'd suspect that is really bloody difficult considering that euclidean circles is a trigger sequencer and as such does not sequence pitch...

What Jim said ;-)
I do, you can, use Euclidean patterns to drive other things that create pitch.... send those Euclid triggers to an Arpeggiator or other pitch sequencer, even send them to a Turing machine + Quantizer or Marbles etc. You can dial in different patterns on the Euclidean or control those via CV for always evolving patterns.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
