The Sirius and MIDI
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.
Example 5: SIRIUS as Expander + Synthesizer (Keyboard) + Computer
This example corresponds more or less to the previous examples. The only difference is that now the Sirius is taking on the part of
an expander. Should your master-keyboard be a synthesizer you will only pay attention to the fact that the MIDI-receive channels of
the Sirius do not conflict with those of the synthesizer. The MIDI receive channels of the Sirius can be set in Edit-System menu page
3.
With this configuration you will unfortunately have to sacrifice some of the advantages of the Sirius.
It is, for example, not possible to record the dial or wheel movements of the Sirius because the MIDI-OUT of the Sirius is not
connected with the MIDI-IN of the computer. It is the same for the data storage using MIDI-Data-Dump. If you absolutely depend
on this connection-setup you will have no choice but to change the connections before a data-Dump can be performed. In our
example you would have to connect the MIDI-IN of the computer with the MIDI-OUT of the Sirius. (In a lot of cases it is not
advisable to change midi connections while the equipment is still powered up.)
This configuration is also open to expansion. If you want to connect a further Midi-device in addition to the Sirius connect the
MIDI-THRU of the Sirius to the MIDI-IN of the extra Midi-device.
