I can't help thinking this just replaces one form of mechanisation with
another. Even when recording step-time I have all forms of grid locking
turned *off*. Notes are very rarely actually on the allotted beat.

For preference I'll input via a MIDI keyboard, and if the part is
particularly difficult I'll play maybe just 4 bars, then rinse and
repeat. Doing this I've learned to recognise the pattern various
rhythms produce in a matrix editor, which is useful in it's own right.

Unless you're doing some techno stuff I regard any form of quantisation
as an admission of failure.
