Logic Pro 7: EVB3 produces no sound when using channels 4 to 16

You insert an EVB3 in the input slot of an Audio Instrument, but there is no sound output when playing the organ live with a MIDI keyboard or trying to play back a MIDI region on this track. What's going on?

Unlike all other Logic Pro Audio Instruments, the EVB3 accepts MIDI input only on MIDI channels 1-3. MIDI data with other channels (4-16) will be ignored. If the track's MIDI channel is set to a value beyond 3, the EVB will therefore remain silent.

Because organs usually have two manuals and a pedal, so does the EVB3. MIDI data on channel 1 or 2 plays the upper or lower EVB3 manual respectively, MIDI channel 3 plays the pedal. Set the MIDI channel of the EVB3 track to a value between 1 and 3 to play one of the manuals or the pedal.

The MIDI channel parameter

If you set the MIDI channel parameter to "All," the MIDI channel of your MIDI keyboard will be passed unfiltered to the EVB3. Choose this setting for a split keyboard or a dedicated organ keyboard setup. You may then set a dedicated MIDI mode in the EVB3 graphical interface.

For further information on this kind of MIDI setup, please refer to the EVB3 section of the Logic Pro Plug-In Reference manual.
