Roland RPU-3
Here's a super-convenient 3-pedal piano pedal from Roland. The PRU-3 piano pedal takes three of Roland's high-quality piano pedals and combines them in the a unit that's super convenient and easy to use. What's really cool about the PRU-3 is that it's got three discrete outputs, so you can use the PRU-3 with lots of different digital pianos and keyboards. Even better, when you use the PRU-3 with your Roland FP-7F or RD-700 series piano (or any other Roland keyboards equipped with half-damper capability) you get even more out of your rig. You can even use it to access the FP-7F's looper and harmonizer on the fly.
