Sample accurate timing.

All driven at signal rate now, and resettable with a signal as well.
This should tighten up timings in sequences so there isn’t any lag from
the scheduler.
Sample accurate timing / fix for dict crash

I swapped in multi sliders in blob mode instead of the single dict.
This will keep the audio processing from going through the gui, and
will let the whole thing run faster.  The metros are now outputting
click~s into the gen~ object which counts them.
