I am currently looking into getting a keyboard to use in jamming sessions. I have so far been partial to Roland GO:KEYS 5 (this over the 3 due to the additional inputs and an acceptable imo price difference). This (around 500 EUR) is around the max I want to give for it.

But, as far as I can tell, it does not have a proper loop function. It has a layered recording-function, but this would require me to play through the full song.

So I have two questions:

1. Are there any keyboards anyone of you would recommend in roughly the same price range that has a looper?

2. Could I use my Boss RC-5 for this, plug the keyboard into input A and plug it back into the keyboard from output A? I would like to avoid buying a new speaker for this, and tge loop pedal would also be connected to my guitar and to the amp.
