More Dice! (per Instrument)

And then there is the inverse, individual locks:

Locks would be the one-click way to say "don't roll with the big dice, for now".

Individual Dice and Locks are in service of 

1.  lightning-fast auditioning of combinations for later use

2.  careful specification of evolving change during live performance

    

Two situations I find very common when rolling the Dice   -  

1.   Drums and bass sound very good together, the rest not-so-much.
2.   The "rest" sound very good together, drums and bass not-so-much.

I think using individual locks along with individual dice would be the 1-click fastest possible way to keep everything judged good and continue to generate everything that still falls short.
