On the standard size keyboard I can play an octave comfortably, but a ninth is a stretch. I have relatively small hands - 7' from joint at wrist to tip of longest finger.
The Casio is a standard size weighted keyboard. I currently have a Casio CGP-700 that I really like to play.
I think I want a small synth like the Yamaha Reface DX. I'm giving up on wanting a small weighted keyboard. I posted the original question months ago.
