remove all midi connections from plugin

[VirToReal]

I'm using a novation Launch Control XL and connect it's knobs to a plugin, for example Triple OSC. After generating a nice sound, I have to disconnect every midi knob in order to save my creation as a preset. Because the midi connection will be saved in the preset-file (which is really great), but all knob positions will be set to zero. But even while removing the connection, the value of the knob which been set by the midi-input gets lost.

If there would be a button to erase all midi-connections, and set its last midi-value as it's actual value. I would be able to save one preset as midi-preset, using this for creating sounds via launch control. Then deleting all midi connections while setting its last value to the actual value of the plugin and save it as a real preset.

Are there more use-cases for "remove all midi connections"? If preset saving is the only one, I can't find a reason for that button.

Not really... just leaving the last midi-value on the knob while removing the connection would be great. Removing every connection would be nice, if there are, for example on the triple oscillator, all knobs connected to a midi-controller. Or maybe just a keyboard shortcut for removing the midi-connection while pressing the connected button/knob.

In each case of course, the midi-value should be placed on the actual value of the knob/button while removing the midi-connection.
