If, during the shutdown process, the Instrument objects get deleted before the
Hydrogen instance, that would cause such an invalid read (because I altered
Sampler::stop_playing_notes() in a way that it accesses the instrument
attached to each note, in order to update the instrument's reference count).
I'll try looking into it later...
