I have needed a latch or unlatch pedal for some years and kept putting it off - luckily as it happens as there is now a combined pedal. The pedals also have assignable functionality so if you need two latches, two unlatches or one of each- it can be done.
As with all Roland prducts it is very robust and very quiet, sure footed and not cumbersome.
I use it for triggering drum machines, Boss pedal interfacing, punching in for guitar soloing etc.,
It really is a great pedal and worth the price. Also, remarkably easy to recommend. Roland and Boss says it all!
