Sure this has been mentioned before.. a per track setting to retain parameter locks when disabling a trig would be an excellent addition for live jamming of sequencer steps. Right now I don't even bother cause as soon as a trig is disabled, all the parameter locks are lost.. IMO this one feature could unlock (no pun) a lot of live playability of the OT.
Some usage examples would be:
-specific trigs with mad modulations for transition sounds etc.
-trigs locked to specific samples to bring in and out on the fly
-quickly bring in and out sections of sliced loops
-lots of finger ninja oportunites ..
-less staring at the OT waiting for the right time to move the crossfader
