What was the Roland Arranger that was just a short keyboard, maybe 37 keys ? Made to go on top or next to a piano and played with the Left hand while playing piano with the right. I borrowed one once from my friend who had a small music store but I remember It was too clumsy to use live, at least for me at that time.
