EMU ESI-4000: Setup of SPDIF Output

MIDI & MULTIMODE

SPDIF and FX can also be utilized but are not separate busses and cannot be used to expand the number of discrete outputs. In the case of a multiple output setup, SPDIF or FX would be used as an alternative to the analog Main Output bus. This is an advanced configuration which is explained later in the SPDIF/FX section.

SETTINGS CONFIGURATION

MASTER/SPECIAL/OUTPUT FORMAT —
Main Output Format: analog

MASTER/MIDI/MULTIMODE ENABLE —
Boot in Multi: yes
Use Bank State: no

MASTER/MIDI/MIDI MIX —
Change the bottom lines from ‘zzzz zzzz zzzz zzzz’ to ‘M123 zzzz zzzz zzzz’ (for 4 stereo busses) or ‘MM11 2233 zzzz zzzz’ (for 8 mono outputs).

This is assuming MIDI channels 1-4 for stereo output, or MIDI channels 1-8 for mono output. Different MIDI channels and stereo/mono combinations can be configured, but–for the sake of simplicity–this guide will assume either all stereo or mono instruments and MIDI channels 1-4 or 1-8.

 

Effects Setup

To configure SPDIF/FX to be a mirror of the main output bus instead of the entire effects processor output:

MASTER/EFFECTS/EFFECTS SETUP —
Effects: Bypassed
Multimode Control: master settings

Alternately, SPDIF/FX can be used as a wet version of the main output bus. Either Effects A, Effects B, or A & B can be applied to the main output signal and routed to SPDIF/FX.

To configure SPDIF/FX as a wet main output bus:

MASTER/EFFECTS/EFFECTS SETUP —
Effects: Enabled
Multimode Control: master settings

MASTER/EFFECTS/MASTER EFFECT A —
(cursor right twice)
Sends:
Main = 0-100% (set to taste)
Sub1 = 0%
Sub2 = 0%
Sub3 = 0%

MASTER/EFFECTS/MASTER EFFECT B —
(cursor right twice)
Sends:
Main = 0-100% (set to taste)
Sub1 = 0%
Sub2 = 0%
Sub3 = 0%

The important concept when using the SPDIF/FX outputs is that the effects processor either needs to be disabled entirely or effectively disabled for Sub1, 2, and 3 by having all submix FX sends set to 0%. Also, since this type of multiple output setup make it impossible to use (in any meaningful way) the ESI’s internal effects on the submix busses, any patches needing internal effects should be assigned to the main output exclusively.
