I just got round to looking seriously (well almost) at Rosegarden Midi 
Sequencer. Got it linked to jackd which was fortunately installed 
effortlessly by Mandrake. Rosegarden suggest a series of command-line 
arguments producing:

/usr/bin/jackd -d alsa -d hw -r44100 -p 2048 -n 2

It is clear that jackd has been invoked since the odd message appears saying 
it's being overloaded. However, it is also clear that there is absolute 
silence when playing a midi file and all system sounds are switched off and 
stay so until the system is re-booted. CD plays normally.

Any suggestions please?
