Default pitches are very high

This is only noticeable with economy mode off, so not of high priority.

Patching the code so that the final VCA never closes yields high pitches from the oscillators before the voices have been assigned. The MIDI pitch has a default value of 30 but the oscillators are playing much higher.

The high pitch means that the as-yet unassigned voices consume slightly excessive amounts of CPU time as the antialias code is run more often.
