"CLICK CLICK"
i am not sure what you mean about "click click". what type of controller do you use? if you have a control surface there is no "click click". if you have the bare minium of hardware controller(s) i do understand exactly what you are saying but with a control surface there is no "click click".
to each its own but my problem with mpc is that it take too long to get the music going. for "me" with software once the app is open i have access to all my sounds/samples. whether battery for drums or lounge lizard for electic keys or trilogy for bass, i have those sounds/samples at my finger tips. flipping thru the load page on the mpc takes away from "my" inspiration, it just takes too long.
it also depends on your workflow. if you sample from a turntable/cd player/ipod into your mpc, set loop points and add drums/hits to the loop the mpc is ideal (no question about that). if your workflow is more like a band (drum, bass, guitar, keys, horns, strings) the mpc is not ideal for this workflow. yes, it can be done on the mpc but done easier with software (especially saving the project).
p.s. no fames today not in the mood but i am talking from experence. i have own yamaha b200 (keyboard sequencer), roland mc-50 sequence, roland mc-50 xl (the one with the sounds included) mpc 2000 classic, cubase 1.5 (now sl 3), band in a box, pro tracks, live4, reason, acid, cakewalk and have own a project studio for over 20 years basically i have "personally" seen the growth in technology and if you do not like the "click click" of sofftware get a control surface and there will be no "click click".
last point, what is "midi learn" for?
