The Sirius and MIDI
105
Example 4: Co Expander
In this example we are already dealing with a small MIDI-studio. This example expands on what we
have previously discussed and assumes that you have one MIDI-IN and one MIDI-OUT on your com-
puter only.
In order for the computer to send data not only to the Sirius but also to the Expander you have to
connect it to the socket MIDI-THRU on the rear panel of the Sirius. The MIDI-THRU socket passes
on all Midi-data received through the MIDI-IN socket to the expander without changing it. To avoid
doubled up sounds you should adjust your expander so that it will only receive on the MIDI-
channels which are not already being used by the Sirius. The factory setting for those on the Sirius
are MIDI-channels 1-7. Let´s assume that you have set your expander to the MIDI-channels 8 to 16.
If you now want to play the sound of the expander, located on channel 8, and you are using the key-
board of the Sirius, you will have to select a free track in your sequencer-programme and set it to
MIDI-channel 8. Naturally the Sirius is in this example in Local-OFF mode.
If your expander also has a MIDI-THRU socket, you can connect another expander to this. Instead of
the expander or sound module you may of course connect a sampler or another midi-synthesizer.
