i would be great to have in chromatic mode the posibility to play with parameter lock for each key.
for instance:
if i play a C in chromatic mode i would play the sample standare but i play the c# i would play the same sample with more delay or perhaps another sample.
I would help me to play live with more creativity.
I don’t think this is possible. parameter locks and conditional trigs are only possible when using the sequencer.
If the DT would have the MULTI MAP mode like the Digitone has, maybe this could be possible, but at the present time you have to use your fingers 
It’s not possible to do that in chromatic.
A little workaround I use sometime is to copy your track on every 8 track on another pattern, and change the parameter I want on each (start point, filter, etc…)
Then I turn on the metronome, go into sampling menu and set source at INT L+R. I press play and I hear the metronome to play my new melodie. I resample it into a new track (the metronome is not recorded when resampled internal)
Set this new sample back into my pattern and voila.
