Tobias Doerffel 2dc02001b7 Instrument: also render sound for MIDI-based instruments when muted
In order to provide smooth muting functionality (i.e. immediate proper
sound when unmuting) always render audio buffers for MIDI-based
instruments. This is more important than potentially reduced CPU usage
while muted.

Closes #69.
