Mono Legato Mode
Browse files Browse the repository at this point in the history 
Mono Legato mode differes from Mono Retrigger mode in taht nodes
get moved and rather than terminated and restarted. This implements
that mode by adding two new api points to the voice manager and managing
the internal state accordingly
