This is only going to work if you use the 'wait until the 'one'' system, unless your timing is supernaturally accurate. The slightest inaccuracy will throw off the groove badly.

However, the Roland also does the other, 'instant on' system if you need it, as well. Handy for throwing special effects into a song, for instance.

But the 'wait for the one' system seems best for most uses, because if you change the tempo, the timing of the start of the loops (and their time-stretching) will all remain constant.

AJ... can the Ketron play multiple loops at the same time (for layering say a conga pattern with a tambourine loop for instance)? If so, can it be defeated? One of the important things about this idea is that the first loop MUST stop as soon as the second starts, or you will have two sections of the song playing at the same time.

I have been in contact with Roland about this, but it occurs to me that moving the loops OFF the keybed to say the FC-7 (or in the Audya's case, the touchscreen) would make a lot of sense. With something as critical to the backing as this would be, hanging out on the notes where you might accidentally play them is making more risk than it needs! Imagine the train wreck that might occur should you inadvertently hit the wrong key..!

It makes sense to offer an alternative way to trigger these other than keys.
