Hello people,

I have been trying to get my head round the XX-7 sequencer, I like 
it but jumping from 10 years on Cubase / Logic is quite a shift ...

Quick editing of patterns is a must - how do you guys go about it? 
Record, then move off notes..? 
Also I want to be able to shift patterns around, live as its 
playing... is this possible or do you have to stop every time?

Also, for playing live I was hoping I might be able to swap tracks 
within a playing pattern, like swapping a drum track for one with a 
nice fill for an end of a section, then going back to the straight 
loop... It seems the way to do this is use the loop function, having 
say 8 bars of the main loop, then 8 bars of a fill section - keep it 
going round till you want a change then allow it to cross into the 
fill section.

Also, is there any way adding swing to an Arp pattern??
 
Thanks!
