The only time I use Step record is for editing purposes and Control/Program change messages.
>"when i sample some thing and chop it up i.e vocals, string,guitar sound and record it in a sequence it sounds choppy like when i switch form pad to pad there is like a space in the seq. when i switch from pad to pad it alsmost sound like the quantizzation is off....."
Provided your samples are tightly chopped and your tempo is correct, you can use Step record to edit the duration value of the sample (if the overlap is set to Note Off). Sometimes the note isn't held long enough for a smooth transition and sometimes its held too long and either cuts off the next sample or sounds sloppy.
You could set one sample to mute the previous sample (the way you'd set up your program for the "open/close hi hat" effect). If it don't sound smooth then, you know you got chop or tempo issues to deal with.
Editing advantages with Step record:
Easily isolate events to be altered/erased. For example, if you liked your performance in real time, but there are small details you wanna change (notes played too loud things of that sort), you can adjust them there.
If you use a synth for guitar parts its useful to input pitch bend data in Step record. It sounds more realistic.
If I use the sliders on my controller keyboard to alter sound I can input values that I couldn't posibly do in real time (good way to make syth parts sound like samples).
I'ma quit ramblin... but to make a long story short. I build tracks in real time and freak 'em out in step.
