The Sirius and MIDI
103
Should the midi TX of the sequencer track of the Sirius correspond to the Midi RX of the selected
part of the external device, simply activate the "Part/Sequence to MIDI"-function of the Sirius for the
relevant Part.
Naturally this example will also work for a keyboard-synthesizer.
Despite the extensive possibilities of the Sirius-sequencer maybe you´d rather use your usual se-
quencer software. Again the Sirius is well suited to this because its synthesizer can be addressed and
controlled via MIDI. Because this subject is quite extensive we´ll have to go far afield to get to some
particularities resulting from a connection of Computer and MIDI. You will find a diagram for this ex-
ample on the following page.
The basic requirement for this MIDI-connection is that your computer is equipped with a MIDI-
interface. The ATARI ST has the MIDI-interface built in. PC and MAC need an additional interface,
usually in the form of a card or an external Midi-interface unit connected to the printer or modem-
port. Modern PC-s often have a sound card built in which includes a MIDI interface. In this case you
will need the MIDI connection cable that goes with the sound card (obtainable at your Computer-
Specialist or the manufacturer of your sound card). Unfortunately it is important to note that the
MIDI-interfaces of sound cards are not always terribly reliable. Should you plan on getting further
MIDI-instruments later you should also consider the purchase of a "proper" MIDI interface. These de-
vices often offer several MIDI-interfaces in one casing so that you are not restricted to 16 MIDI-
channels anymore. There are interfaces with up to 128 MIDI-channels or 8 MIDI inputs and outputs
(8 X 16 channels in, 8 X 16 channels out).

This diagram shows you
how to connect an ex-
pander, a sampler or any
other synthesizer with MIDI
to the Sirius. This way you
can play the sounds of the
connected device with the
keyboard of the Sirius.
