Hi list,
I have a script that needs to disconnect various jack connections. Works

fine with client/port names without spaces, like this:
jack_disconnect pure_data_0:output0 system:playback_1
Other port names (specifically, ALSA MIDI port names) however have

spaces in them and don't seem to work with jack_disconnect. Have tried

putting quotes around the names, eg.
jack_disconnect 'Pure Data:PureData Midi-Out 1' 'Hammerfall DSP:HDSP

MIDI 1'
and 
jack_disconnect 'Pure Data':'PureData Midi-Out 1' 'Hammerfall DSP':'HDSP

MIDI 1'
Tried double-quotes too as well as underscore characters between the

words but none of these techniques work unfortunately. They result in

error messages like this:
ERROR Hammerfall DSP:HDSP MIDI 1 not a valid port
Nor have i found a way to rename the ports.
Some more detail:
In qjackctl, these ALSA client and port names include numbers. eg.
129:Pure Data
and the port:
1:Pure Data Midi-Out
The HDSP has this too:
20:Hammerfall DSP
and 
0:HDSP MIDI 1
I've tried I think all the permutations of names with numbers, numbers

without names and names and numbers together but I can get none to work;
Any suggestions?
Cheers,
Iain
