I'm new to keyboards- the only one I've ever owned is an MT-640 which I really like. I'm curious if there is a similar sounding Casio keyboard with full size keys. I've had the MT-640 since I was very young and I really like the sounds, it's very dear to me but is in rough shape (missing keys and all). Right now I'm looking for an upgrade and curious what you think is best. I've used the MT-640 on a couple recordings, most recently my Christmas album, which was done on a Tascam 414 (link) https://fountaindew.bandcamp.com/album/christmas-in-the-fridge See attached photo. Thanks!
