I thought that reproduced a 'Play' command of HC with RR&QT. I have no idea about external hardware MIDI. At first makeSMF makes a MIDI file ( makeSMF handler ) and then plays it with 'play vc'. ( playPmd handler ) Does this give a hint to you? UDI eudio at chabashira.co.jp http://member.nifty.ne.jp/UDI/
