Yes... I'm sorry the guy chose such a 'karaoke' (or let's be kind and call it 'remix'!) style loop. One can imagine SO many truly
musical uses for these loop features, and this guy trots out Gangnam Style! Cliche...
I noticed the 'one loop at a time' limitation, but given that there are 7 of them available, you could always think of it as '4 loops and 3 combinations' if you mixed the loops together in an audio editor (very easy to do) in different combinations. Yes, not QUITE as good as having four loops you could layer, but closer than you realize.
I still hope that we can get some pressure put on Roland to allow the FC-7 to trigger them. One hates to have ponied up for a 76, then have the top 7 keys (more like 9 or 10, because you really don't want to be playing anywhere NEAR where you might accidentally hit a loop key!) unavailable for your RH sound...
