Parameter lock for patch loading

This actually goes for FM8 and ABsynth as well.

Use it to lock a parameter, say you set the filter and envelope
just the way you want it, but the sound it self is not perfect, so you lock the filter and Attack,Decay,Sustain,Release. and start loading patches. now it will load patches and change all parameters Except the filter and ADSR it will stay just the way you left it.. This would also be a superb tool for sound designing. i thought of this because i got annoyed of having to turn of the FX Off on every preset and/or that the tempo changes in the global settings for each patch,, unless its set to sync. but maybe im looking for something running at half tempo
would realy be nice to have an Ignore patch value when you right click on a knob,button etc..
