Try getting to work "MIDI Test" from the Demo menu first. That one
should work if the events get there on the right channel. You will see
that the "MIDI Test" consists of two parts (see Combobox): The
instrument (which is _not_ configured as auto activate network - that
will not work), and a "MIDI Synthesizer" (these can be created with
Project -> Add MIDI Synthesizer).

Now for the SID: besides loading a SID instrument, create a "MIDI
Synthesizer" or a "Song" (using the project menu), depending on whether
you want to use beasts internal sequencer or an external event source.
Then configure the SID as instrument in the newly added "MIDI
Synthesizer" (or a track in a Song) with the desired polyphony,
postprocessor (effect) and midi channel, and things should work fine.
