Sequences spillover when redefined

[ianhattwick]

When redefining a sequence, the previously defined sequence continues to play (sometimes for a whole pattern) while the new sequence plays.

I've noticed this in various contexts, some worse than others. I'll try and add more examples as they come up, but the example below seems repeatable:

f = Freesound(577698, {maxvoices:8})

//execute this first
f.note.seq([7,6,5], 1/4)

//then execute this
f.note.seq([1,2,3], 1/2)
