this thread got me curious :)

an example using xbindkeys:

setup a script like this for the desired midi switching:

#!/bin/bash
if [ $1 = a ] ; then
    jack_disconnect 'Non-Sequencer:midi_out-1' 'yoshimi-01:midi in'
    jack_connect 'Non-Sequencer:midi_out-1' 'yoshimi:midi in'
elif [ $1 = b ] ; then
    jack_disconnect 'Non-Sequencer:midi_out-1' 'yoshimi:midi in'
    jack_connect 'Non-Sequencer:midi_out-1' 'yoshimi-01:midi in'
fi

for testing, invoke it with its arguments

./jmidiswitch.sh a
./jmidiswitch.sh b

install xbindkeys

create an appropriate file ~/.xbindkeysrc, containing:

# xbindkeys configuration
"$HOME/jmidiswitch.sh a"
  Alt +a
"$HOME/jmidiswitch.sh b"
  Alt +b

run xbindkeys,
     and happy switching.

IIRC only jack2 allows for click-free port switching,
the tests I ran with jack1 and jack2-svn confirm this.

best,
d
