[CM] midi on Ubuntu

[adam]

I´m trying the pre-compiled  Grace-3.7.2-ubuntu.zip  version 
on a fresh install of Ubuntu DreamStudio by MacInnis. 

So,  
Audio>Audio Settings> Test   and a tone is heard, 

Audio>Midi Out> Test Output  (TiMidity (1) selected)   and no 
output is heard. 
Nor when either; SB Live! (CT4620), or Emu10K1 (wavetable 1) 
is selected. 

In Help>Tutorials>Sal>Midi Output; 

ports()  -> 
> {{"midi.port" {0 -> "Midi Through" #f} {1 -> "SB Live! [CT4620]" #f} 
> {2 -> "Emu10k1 WaveTable {1}" #f} {3 -> "Emu10k1 WaveTable {2}" #f} 
> {4 -> "Emu10k1 WaveTable {3}" #f} {5 -> "Emu10k1 WaveTable {4}" #f} 
> {6 -> "TiMidity {1}" #t} {7 -> "TiMidity {2}" #f} 
> {8 -> "TiMidity {3}" #f} {9 -> "TiMidity {4}" #f} 
> {0 <- "Midi Through" #f} {1 <- "SB Live! [CT4620]" #f} 
> {2 <- "Juce Midi Output" #f}}}


send("mp:open", out: 0)  ->
> 0

send("mp:open", out: 6)  ->
> 6

send("mp:midi", 0, .5, 60, .5, 0)  ->
> #<unspecified>


Running Timidity -iA at a commandline elsewhere simply adds {5} {6} 
{7} {8} to the Ports() list. 

Any help or suggestions much appreciated.
