Summary 0007775: unix midiplugin cannot play standard instruments via ALSA midi connection
Description The MIDI plugin is expected to be able to play sounds using the standard MIDI instrument list; on unix with ALSA sound drivers (i.e. on the Raspberry Pi in this case) this seems not to work. Apparently this has been a problem for some time since the Scratch code using it has been commented out since 2009.
The result is that a lot of sounds are very sub-par for the users of Scratch on any unix platform and of course the Pi. This is a pity, since it gives a very poor impression.
Additional Information After gazing at the unix midi code I had to conclude that it didn't look like it could work at all, but what do I know? At the simplest level, querying the number of ports seems to give an answer that classes with related functions that get passed a port number. Compare, for example, sqMIDIGetPortCount and sqMIDIGetPortDirectionality
