There are signal paths inside EMU10K1 and EMU10K2 called FX buses. The
samples from MIDI wavetable engine go through two FX buses (left and
right) and samples for reverb and chorus go through extra FX buses, so
the signal is not mixed. Check for FX buses in emu10k1.h:
#define FXBUS_MIDI_LEFT 0x04
#define FXBUS_MIDI_RIGHT 0x05
#define FXBUS_MIDI_REVERB 0x0c
#define FXBUS_MIDI_CHORUS 0x0d
